The GE Gas Turbine Control Board DS3800DADB features one 20-pin ribbon cable permanently attached to the board and 3 pin-type connectors. The GE Gas Turbine Control Board DS3800DADB also is populated with terminals for attaching a variety of components. The board is 3.5 inches in height and 6 inches in length. It is designed to fit inside the drive in a board rack with spaces for many types of boards and other devices. The boards are optional devices that provide different functions for the type of processing the site requires.

The 20-pin ribbon cable provides signals to command the board to perform some processing functions. Some of the signals are sent to the board from other boards for processing. Other signals are transmitted to other boards and components. Because the ribbon cable is short and is attached permanently to the board, it is important that you use good practices when you disconnect the ribbon cable.

Never grasp the board and pull the ribbon cable out of the connector to which it is connected. This action can easily disconnect the fine wires from the connector at the end of the ribbon cable. You will notice that little support is provided to the ribbon cable so care must be used. To disconnect the ribbon cable, grasp the connector at the end of the ribbon cable and pull it out of the connector on the board. Occasionally inspect the ribbon cable for signs of wear between the connector and the ribbon cable. Notice if the wires appear to have pulled free of the connector and replace the ribbon cable if that has occurred.

The GE Gas Turbine Control Board DS3800DADB1A1A also is populated with terminals for attaching a variety of components. The terminals on the board provide you with great versatility when installing the board. Without the need to modify the board or solder new components on the board, you can add components to the terminals that will change the processing performed by the board.

To add a component, use a screwdriver to loosen the screws on top of the two terminals between which you will add the component. Use the information provided with the board from the manufacturer for a description of the use of the terminals. Then, slide the lead wires in the terminals. Tighten the terminals when you are ready. The components can be removed or replaced at a later date, if necessary. Make sure the individual who is adding components to the board has a good understanding about the board and how the addition of the components will change the operation of the board.

Another way to change the operation of the board is to configure the board using the jumpers. The 3-pin jumpers each has 2 positions. One position is when the jumper covers pins 1 and 2. The other position is when the jumper covers pins 2 and 3. The information supplied by the factory describes how the jumper settings change the processing of the board. Each jumper has a default position. It is the position the jumper is set for when the board comes from the factory.

The GE Multi Cony Coordinator Auxiliary Board DS3800DCCB is also populated with 1 20-pin ribbon cable that serves as the main signal connection to other components in the drive. The ribbon cable is approximately 8 inches in length and it is permanently attached to the board. It plugs into a connector near the board in the interior of the drive.

Because of the short cable length and the tight space inside the drive you might attempt to pull the board out of the drive and tug the ribbon cable out with it. However, the ribbon cable is easy to break and cause the fine wires in the ribbon cable to break away from the plastic connector. If the connection is broken the signal will not be completed. To save the ribbon cable from damage, always hold the connector at the end of the ribbon cable when you disconnect it. When you are ready to connect it, also hold the connector at the end of the ribbon cable. Align it with the connector and press it into the connector on the board.

If you have reason to believe the ribbon cable is damaged, inspect the connector at the end of the ribbon cable and look for evidence that the connection is broken. You might see extra space where the wires have pulled away from the connector.

The GE Multi Cony Coordinator Auxiliary Board DS3800DCCB1C1C will provide reliable service when properly installed in the drive. However, the need might arise for you to replace the board. To do that requires some consideration and planning before you start. To prevent electric shock and burn, you must remove all power from the drive as the first step.

The drive will have multiple sources of power and all of them can cause a safety concern if not removed from the drive. If you are not familiar with the power supplies connected to the drive, confer with an engineer or installer who is familiar with the installation of the drive. Rectifiers are used to deliver DC power to the drive and they can be disabled by a switch or by removing the fuses from it. If the drive has an AC power source, the current can be removed by moving a switch or a disabling a circuit breaker.

It is important that you use a tester device after you have removed current from the drive to verify that all power is absent from the drive. Without touching any components, use insulated probes and a reliable tester to check for power.

The GE Printed Circuit Board DS3800DCMB features 1 40-pin connector and multiple erasable programmable read-only memory (EPROM) modules. It also is populated with 4 indicator LEDs, 7 jumpers, and 1 20-pin connector.

The EPROM modules are populated on the board to store the firmware and other code to perform the normal processing functions. When the original board from the factory arrives at your site the EPROM modules include a basic set of code that you can configure for the exact requirements of the site. The configured code instructs the drive to perform the steps you require. To configure the code there are 2 methods available for editing. One is to use the control panel on the drive to edit the configuration file. The control panel has keys that enable the operator to make small edits of the file. The control panel uses a menu of selections as the user interface. The menu selections enable the user to access the various sections of the configuration file.

The most common method to edit the configuration file is to download the file to a laptop or other device. The download is accomplished through a serial cable connected to the laptop serial port. The other end is connected to a serial port on the drive. You can also load a full function editing program on the laptop. When the editing is complete, upload the file back to the drive using an upload function available from the drive control panel.

The ID of the jumpers are suffixed with JP and end with a one-digit number. For example, JP1, JP4, and JP9 are IDs of 3 jumpers. When you replace the board use the IDs to move the jumpers on the replacement board to match the positions on the old board.

There are some important factors to consider when you replace the board relating to the jumpers. When the original board is received from the factory and installed in the drive, the jumpers are set to configure the board for use at the site. Best practice is to review the configuration options with the engineers, management, and operators at the site and decide on the configuration settings to use. Place the board on a clean desk or workbench and use a wrist strap to guard against static buildup. Set the jumpers as required by the site.

The default setting is the position of the jumper when the board is received from the factory. It is the most common setting used for the jumper. The 3-pin jumpers have only 2 valid positions. One position is when the jumper covers pins 1 and 2. The other position is when the jumper covers pins 2 and 3. To move the jumper pull the jumper from the pins it covers. Then, align the jumper with the appropriate pins and press the jumper over the pins. The jumper make a signal connection between the 2 pins it covers.

If the LEDs are not flashing and the board is receiving power, it means that a problem might exist with the board. One troubleshooting step is to use the diagnostic tools available on the drive to determine the health of the board. The diagnostic tools are available from the user interface of the drive control panel. From the control panel you can also upload and down files using a serial connection between a laptop and the drive.

The diagnostic report gives a list of all the errors and warning issued by the drive. It also lists the trip conditions encountered by the board. Trip condition automatically shut down the drive when a threshold is exceeded. They are designed to protect the drive from damage. For example, if the interior of the drive is hot enough to damage components, the drive automatically shuts down and gives the drive an opportunity to cool down. Another trip condition is overcurrent, which is generated when the drive is receiving too much current.

The 40-pin connector is the primary cable by which signals are transmitted from the board and also received by the board. The ribbon cable is approximately 8 inches long because it is engineered to plug into a connector that is only a short distance from the board when it is installed in the drive. A maximum of 40 separate signals can use the cable for transmitting and receiving.

The ribbon cable is easily damaged, so before you unplug it consider the following information. To unplug a ribbon cable, do not tug the cable because it will separate the ribbon cable from the connector. This is the case because the fine wires that comprise each connection are easily separated from the plastic connector. Instead, place your hand on the connector and pull it away from the board to disconnect it. To reconnect the ribbon cable, use one hand to hold the connector at the end of the ribbon cable and align it with the connector on the board. Press it into the connector when you are ready.

Once the board is installed and the drive is operational, you can view the LEDs to monitor the operation of the board. The IDs of the 4 LEDs are TXDA, RXDA, DTSA, and CDA. When the LEDs are flashing, it shows that processing is taking place

Some of the signals are received by the board while others are sent from the board to other boards and devices.

There are several steps you must take to protect the 20-pin ribbon cable when you remove the board from the drive. First, disconnect any of the 10-pin cables and move them temporarily out of the way. Then, grasp the 20-pin connector with one hand and gently unplug it. Use one hand to remove the 4 screws that secure the board in the rack. Use your other hand to hold the board in place. When all the screws are removed, remove the board from the drive. The 20-pin ribbon cable can be damaged if you hold the board and tug the board to disconnect the ribbon cable.

The board is 6-inches in length and 2-inch in height and the interior of the drive is equipped with a location specifically designed for installation of the board.

The GE Excitation Power Board DS3800DEPB1A1B features 1 20-pin ribbon cable and 5 10-pin connectors. The GE LCI Exciter Control Board DS3800DECA1B1B1 also is populated with 4 terminals for adding components, and 2 trimmer resistors.

The GE Excitation Power Board DS3800DEPB1A1B is installed in a drive that can be shut down automatically if the interior of the drive becomes too hot. As a protective feature, if the drive temperature rises above a threshold, the drive automatically shuts down. The automatic shutdown is referred to as an over temperature trip condition. Other trip conditions can also shut down the drive. If too much current enters the drive, an over current condition can automatically shut down the drive. An overload conditions occurs when the workload stresses the motor and other moving parts.

To avoid an over temperature condition, you must carefully plan the installation of the drive. The drive must be located in a room with cool air in an environment that is free of oil, dust, and harsh chemicals. Make sure that open space is available on all sides of the drive. This allows air to more freely and carry heat away from the drive. If fans are required to keep the room cool, make sure enough fans are available and that they are in good working condition. In some environments, hoods are installed to draw heat away from a drive and other devices. Make sure the hoods can move the heat away rapidly and that they exhaust the warm air away from the room.

The GE Excavator Ref Board DS3800DERB features 24 single-pin connectors and 8 trimmer resistor components. The GE Excavator Ref Board DS3800DERB also is 5-inches in length and 2-inches in height.

The 24 single-pin connectors can support up to 24 separate cables and due to the large number of cables consideration must be made to route the cables to avoid problems. The drive generates heat while under normal working conditions and it depends on a supply of cool air to keep all components in the interior of the drive cool. To keep the temperature within a normal range, air enters the drive at the bottom through air vents and removes heated air surrounding the components before exiting the drive at the top. Due to the large number of cables connected to the board, the air might be blocked from cooling the drive. Make sure the air vents are not blocked by the cables and that the cables don’t block cool air from reaching components.

Keep the cables routed along the outside edge of the drive interior and away from any power cables. The power cables will radiate energy that will interfere with information carried by the signal cables. If the signals are interfered with, inaccurate signals will degrade the accuracy of the signals received by the board and transmitted to other boards in the drive.

If the drive overheats, the drive might reach the overtemperature threshold and automatically shutdown. This is called a trip condition that is a safety feature to prevent damage to the board.

The single-pin connectors attach to cables with male pin connectors. Each single-pin connector is designed to carry a specific signal so it is important to refer to the documentation that is available about the board for information about the single-pin connectors and what cables to attach to them. Each single-pin connector is assigned an ID. As you review the documentation about each single-pin connector, use the ID as a reference between the description and the board. To connect a single-pin cable insert it into the connector until it is securely attached to the connector. To remove it from the board, hold it by the connector and pull it out of the connector.

To prepare to replace the board, if the original board has stopped processing or is exhibiting intermittent problems, mark the single-pin cables with the ID of the connector it is attached to. You might plan to use tags on which to write the ID. Another strategy is to use masking tape wrapped around the cable as a surface for writing the connector ID.

When you are prepared to reconnect the cables, connect the cables to the same connectors on the replacement board. You will find that fewer errors will occur and the drive can be restarted without problems. It will also reduce the amount of time the drive is offline.

You can adjust the potentiometers from 0 to 100 using the dials. Only a qualified individual should adjust the potentiometers to avoid damage to the board. The servicer or installer must have a calibrated tester on hand when the adjustments are made. It is best practice to adjust 1 potentiometer at a time. Once the correct adjustment is made for 1 potentiometer, move on to another potentiometer. Keep in mind that, the potentiometers enable you to adjust the amperage, voltage, and other aspects of the circuits.

To use the tester to adjust the potentiometers, touch the probes to the test points on the board and at the same time turn the dial of one potentiometer. It is best practice to record the setting and keep it with the other important information about the board. When you install a replacement board, before you install it, set the potentiometer to the same settings as the defective board. To be sure that the setting is right, use a tester to verify that the circuit readings are the same.

The jumpers on the board enable the installer or servicer to configure the board. The IDs of the jumpers are suffixed with the letter J and prefixed with the letter F. The middle position is reserved for a numeric value. For example, J1F, J6F, and J7F.

The GE Firing Circuit Board DS3800DFCF is installed in a high-voltage drive that can cause a serious electric shock to anyone who touches components inside while the power is present in the drive. Electric burns can also occur. Besides the dangers of electric current, the powerful motor and other moving parts can injure individuals. For these reasons, servicers and all qualified individuals must take precautions before starting any service or maintenance procedures.

First, examine the floor surrounding the drive and determine if it is moist from condensation or has standing puddles of water. Clean up any water and if condensation is a problem, use dehumidifiers to prevent condensation from building up. Inspect the area for ungrounded electric cords. Remove any ungrounded electric wires because of the danger from electric shock. No ungrounded devices should be in the area surrounding the drive also. Clean up oil or grease on the floor with detergents. The oil and grease present a hazard while working on the drive.

Locate all the emergency electrical shut off devices that shut off power to the drive. You should understand that multiple sources provide current to the drive and that the drive is not safe to touch until all power is removed. Make sure the emergency cutoffs are in good working order and that they are easily accessible in an emergency situation.

Cables with the male single-pin connector attach to the single-pin connectors on the board. The connectors provide command signals to the board for processing. Some of the single-pin connectors transmit signals to other boards after processing. The written installation guide describes what signals to connect to the single-pin connectors. Once you have completed the cable connections, it is best practice to make notes on how the cables are attached to the single-pin connectors. If it is necessary to replace the board or remove it for repair, you can easily reconnect the single-pin cables.

Because the board might have a maximum of 17 single-pin cables connected to it, you must consider the proper method to route the cables in the interior of the drive. The 17 cables bundled together can block the flow of air through the interior of the drive. The drive uses the free flowing air to remove the heat generated by the components. Route the cables along the outside edge of the interior of the drive. This will allow the cool air to remove the heat. Also keep the cables from blocking the openings in the drive that allow the air to enter and exit the drive. The cool air enters the drive at the bottom and the heated air exits at the top of the drive.

The GE Circuit Board DS3800DFPH features 1 34-pin ribbon cable and 3 trimmer potentiometers. The GE Circuit Board DS3800DFPH also is populated with multiple test points and 1 transistor-transistor logic component embedded on the board. The board is 5-inches in length and 4-inches in height and it also has 1 hole in each corner because it is designed to be mounted in a rack inside the drive. A space is available in the drive for the 4 holes to align with matching holes in the drive rack, You can use 4 screws to mount the board. Use a screwdriver to attach the screws. However, if you drop a screw while mounting the board, locate and pickup the screw before you continue. If you start the drive with a lost screw inside, the screws might create an electrical short and start a fire or cause serious injuries.

Once the board is mounted, plug in the 34-pin ribbon cable. The ribbon cable is permanently attached to the board on one end. The other end terminates in a 34-pin plastic connector. Plug the connector into the designated connector in the drive and make sure it is fully seated. If you see space between the connectors, press it so that the space closes. Only then can you be sure all connectors have made contact.

When you are prepared to remove the board from the drive, with 1 hand firmly grasp the 34-pin connector and pull it out of the connector in the drive. Do not tug the ribbon cable or put tension on the ribbon cable.

The GE Circuit Board DS3800DFPH1A1A also is populated with multiple test points and 1 transistor-transistor logic component embedded on the board. If you have reason to suspect that the board has stopped processing and you suspect a problem with the board you can first run the diagnostic tools available on the drive.

The diagnostic tools generate a report of all the processing performed by the components. It also lists all the errors and warnings, as well as trip conditions generated by the drive. A trip condition is a serious problem that automatically shuts down the drive to prevent damage. This might be when the temperature in the interior of the drive rises above a threshold or if the drive is exposed to an overcurrent condition. From this information, a servicer or qualified person can in some cases diagnose the drive. If the board is suspected as defective, a qualified individual can use the test points to further narrow the cause of the problem. Unplug the 34-pin ribbon cable and remove the 4 screws that secure the board. Remove the board and have a testing device on hand to test the circuits on the board. There are 2 test points and so you have the opportunity to test 2 circuits.

You can have the board repaired if the problem can be pinpointed to 1 component. However, the board will remain offline while the repair takes place.

The GE Circuit Board DS3800DFPH1B1A also is populated with multiple test points and 1 transistor-transistor logic component embedded on the board. The drive is mounted on the wall of the site and so the selection of an appropriate location must take many factors into consideration. The drive is mounted on the wall using a template for the location of mounting bolts. Use proper hardware for the mounting of the drive because it is heavy and requires sturdy installation hardware. The location must be cool and proper space must be planned for so that the drive has several inches around it for air to flow between all devices.

If devices are crowded on the wall, heat can easily build up and cause the devices to overheat. It is important to inspect the room on the other side of the wall on which you are installing the drive. If it is hot due to drives and other equipment in the room, you might have to cool the room before you install the drive. This can be accomplished in several ways. The installation of fans can force the air to move over the equipment and prevent the heat from building up. Another solution is to install vent hoods that draw heat from the equipment. The air is removed by means of fans that draw the hot air into the hood and it is exhausted from the room.

The GE Circuit Board DS3800DFPH1B1B is installed in a drive that requires special consideration concerning cable routing. The drive is often installed on a wall with other drives. Often other equipment is installed in the room also. All the equipment requires signal cables that carry commands and other information. The drives also require high-voltage power cabling. Also inverters are situated nearby that convert AC current to DC current for use in the drive. The high-voltage current carried by the power cables can interfere with the signal cables. This can lead to corrupted signals and loss of communications between components.

To prevent that, you must route the power cables separately from the signal cables. The higher the voltage, the further separated the cables must be routed. In some cases the power cables can be routed adjacent to the signal cables for a short length. If you are also routing fiber optic cables you can run those along with the power cables because the fibre optic cables cannot pick up the interference. They are immune to interference from high-voltage cables. One solution in some circumstances is to use shielded cable. This stops the interference from corrupting the signals.

Keep in mind that the drive often requires several sources of power so the drive will have several power cables running to it.

To adjust them, use a sharp bladed instrument to open the sealed static protective bag the board is packaged in. Wear a wrist strap and remove the board from the bag. Flatten the bag and lay out the board on top of the bag on a desk, table, or bench.

Have on hand a suitable testing unit to test each circuit and adjust the trimmer resistors for each circuit. Only a qualified installer or servicer will have the knowledge to properly fine tune the board. Another component of the board is a TTL and it serves as the interface logic between integrated circuits.

To install the board once the trimpots are adjusted, have on a hand a screwdriver and the 4 screws with which you plan to secure the board in the drive. Use 2 hands to pick up the board and carefully position it inside the drive. Use one hand to hold the screw in place and with the other hand tighten the screws.

The GE Regulator Turbine Control Board DS3800DGRA1E1C receives control signals from other boards and components in the drive. Once received the signals are processed before being transmitted to other boards in the drive. It might happen that the control signals are unreadable. This can occur if the control signals are out of sequence or have been corrupted by power cable signals or interference from other equipment near the drive. The board is equipped with a restart button that can resolve the issue. When the restart button is pressed, processing ceases on the board for a few seconds. This give time for the control signals to restart and resume in sequence. However, power remains in the board during the restart. This allows the drive to start processing as soon as the board restarts.

The control signals are sent and received by the GE Regulator Turbine Control Board DS3800DGRA1E1C through the 40-pin connectors. The connectors have retention latches that hold the ribbon cable against the connector. To install a ribbon cable, swing the retention latches up and over the connector. Align the ribbon cable with the connector. Use 1 hand to press the ribbon cable into the connector.

If the GE Regulator Turbine Control Board DS3800DGRA1F1C is populated with multiple jumper wires attached to the wire terminals, consider the following information. It is best practice to use short wires if possible. That is, do not use long wires that protrude from the board. The wires might restrict the flow of air over the board. Also keep the wires flat against the board if possible. Make sure the wires are securely attached to the terminals. It is best practice to pull on them to test the connection. Make sure the wires are the appropriate gauge for the current load.

If you are replacing the GE Regulator Turbine Control Board DS3800DGRA1F1C there are several factors to consider before you install the replacement board. Remove the jumper wires from the defective board and install them on the replacement board. Make sure you install them between the same terminals and ensure that the connection is secure. Keep the wires on the board surface, if possible. This will allow the fresh air to remove the heat from the interior of the drive. Another consideration is to set the jumpers to match the settings on the defective board.

The GE Load Balance Auxiliary Board DS3800DLBA also is populated with 7 trimmer resistors and and 1 transistor-transistor logic component embedded on the board. When the board is shipped from the factory, the 12 terminals are not populated with additional resistors or capacitors.

However, under some conditions additional components might be necessary to tailor the board. It is recommended that only authorised installers and servicers add components to the board. To add a component, have on hand a screwdriver and loosen the screw on top of the 2 terminals you plan to use. The terminals are part of various circuits. Don’t remove the screws but loosen them so that the lead wires can be inserted through them. Tighten the screws to secure the components when both lead wires are under the terminals.

The terminals protrude from the surface of the board and so care must be taken that you do not accidently knock the board against the drive or hit other boards in the drive.

The board also is populated with trimmer resistors that can be used to calibrate the circuits on the board. This is useful to tailor the board to process information specifically as required for the drive and how it is used at the site.

Have nearby a small screwdriver and use it to adjust the adjustment screws visible on the trimmer resistor. Use a tester to gauge how the circuit is changed as you turn the screw.

The 12 terminals on the board enable a qualified servicer or technician to add components to the board without modifying the design of the board. It is important that only qualified individuals add components because of the risk of damaging the board or other components in the drive. Also, the servicer and installer must know how to operate a testing device and how to calibrate it before hand.

The 12 terminals enable you to add components to various circuits on the board and so you must know to which circuit to add the component and which 2 terminals are connected to the circuit. You can add a maximum of 6 components between 2 terminals. To add the component, use a screwdriver to loosen the screws on the top of the terminals. Slide the lead wires into the terminals and tighten the terminal screws. Do not overtighten the screws.

Use a testing device to verify that the results you anticipated with the addition of the components are realized. It is important that you perform this activity when the board is removed from the drive and the servicer or installer is wearing a static protective wrist strap. Place the board on top of a static protective bag and work on a desk or table with a clean surface.

The GE Gas Turbine Control Board DS3800DMEB1B1C also is populated with 15 capacitors and 2 trimmer resistors. The board is populated with 2 potentiometers with dial settings and 6 indicator LEDs. It also is populated with test points.

The GE Gas Turbine Control Board DS3800DMEB1B1C is easy to remove from the drive because of the retention levers. The modular connector on the board fits into the modular connector at the rear of the board rack. When you press the modular connectors together, the signal and power connections are made that provide electrical power to the board. The modular connectors also carry control signals. The control signals are received by the board for processing. Then, after processing, they are sent to other boards in the drive for further processing. However, because the board is easy to remove, there a danger of electric shock to the technician.

Before the replacement procedure is started, the drive is removed from all power. The drive receives power from multiple sources. The electrical current can be dc or ac current. It is best to confer with an engineer or other knowledgeable person about the sources of power and how they can be removed from the drive.

However, even when current is removed, the capacitors store power that can cause a shock or burn. Wait 30 seconds for the current to dissipate from the capacitors.

The 20-pin and 34-pin ribbon cables are not cables that can be disconnected from the board. They are attached to the board and they provide the means through which the board receives signals and power from the drive. When you install the drive, you will find that there is a location designated for the board with a 20-pin and 34-pin connectors adjacent to it. First, use screws to attach the board to the rack, then connect the ribbon cables to the designated connectors. Ribbon cables are fragile and require some special consideration.

When you connect the ribbon cable do not put stress on the cable because there is minimal support given to the cable. If you pull on the connector you can easily pull out the strands of wire that connect the cable and the connector at the end of it. Instead, gently grasp the connector and press it into the connector on the board. Make sure there is plenty of slack in the cable. Also, look for space in the connector on the board. Press down on the ribbon cable connector to ensure that all pins are fully seated. When you remove the board, first disconnect the ribbon cable so that it is not damaged if it is pulled out and damaged.

The potentiometers are equipped with dials so that the servicer or installer can easily set the potentiometer to the proper setting. When the original board is received from the factory the dials are set at the default values. These are the settings most often used for the board. However, to achieve another processing value, you can use a testing unit to read the values for the circuit and adjust the dials to refine the board. When you replace the board, you can set the dials for the same values. Best practice is to use a testing device to verify that the dial settings provide the same outcome as you achieved with the original board.

The GE MD Exciter Control Board DS3800DMEC1B1B also is populated with 20 jumpers for configuring the board. The IDs of the jumpers are suffixed with a J and prefixed with an E. The middle section is a numeric value. Some examples are J27E, J28E, and J29E. The jumpers are all 3-pin jumpers. The jumpers all have 2 supported positions. One position is when the jumper is inserted over pins 1 and 2. The other supported position is when the jumper is inserted over pins 2 and 3. The jumper forms a connection between the 2 covered pins and the signal changes the configuration of the board.

The indicator LEDs are a useful tool for the operator to gain insight into the operation of the board. When the board is processing as normal the LEDs are not lit and no further intervention is required. However, if the one or both LEDs are lit, it indicates that a problem has occurred and the board is not processing as expected.

If that is the case, you can first use the diagnostic tools available on the drive. The tools provide information on the processing taking place in the drive. It also provides information on the motor and other moving parts. If any errors or warnings have occurred, the report would also list them. It would also list any trip conditions. A trip condition is a problem that will cause damage to the drive if not resolved. The trip condition causes the drive to shutdown automatically. Some trip conditions are excessive voltage supplied to the drive, exceeding the temperature threshold in the drive, and over loading the motor and moving parts.

The final method of pinpointing the cause of an error is to use the test points to test the specific circuits in the board. This can be accomplished by a qualified individual with a full function testing device.

The GE MD Exciter Control Board DS3800DMEC1D1D is engineered to be installed in a drive that is attached to a wall or other vertical surface. There are several factors to keep in mind when you install the drive that will improve the reliability of the board and lead to a longer life span for the board.

Before you select the location for the drive plan for the power cabling. The main power supply must be equipped with an emergency shut off so that the high-voltage power can be removed instantly. This might reduce injury to individuals or reduce damage to the drive or other equipment in the area. The location you have chosen must also be free of moisture on the floor or puddle of water or other liquid. If the area is prone to condensation or other sources of moisture, use dehumidifiers or other means of keeping the area dry.

Make sure you route and install the proper signal cabling the drive will need. You will also need to have an electrician or an engineer install the high-voltage power supply cabling. This will also include inverters to transform ac current to dc current, if the drive requires dc current for your site.

The resistors are permanently embedded on the board and they are assigned IDs that are printed in the surface of the board. The IDs assigned to some of the resistors are FOC1, FL1, FLD GAIN, FULL FLD, and IA.

The 20 single-pin connectors are typically connected to a device in pairs to complete an electrical circuit. One consideration is that when you plug the single-pin connector into the board, there a potential for damaging the surface of the board by scrapping the pin across it. The best practice is to start by having a good view of the cable and the connector. This is accomplished by looking down on the board. Then, align the pin with the connector and press the pin into the connector. Make sure it is completely inserted into the connector.

The 20 cables attached to the single-pin connectors are bundled together and routed inside the drive. The cables might add up to a large bundle of cables and so care must be taken that they are routed so as to avoid causing problems. One potential problem is that the cables block air from moving through the drive. The air enters the drive at the bottom through vents and exits the drive through vents at the top. The air removes heat from the interior of the drive and exits the drive as hot air.

To use the terminals, refer to the installation instructions that shipped with the original board. It will describe the terminals and the circuits each terminal is part of. Only a trained technician should add components on the terminals because of the risk of damage to the board. Capacitors and resistors can be added to the board and only a highly knowledgeable individual will understand how to obtain a particular result.

Have available a flat-blade screwdriver to loosen the retention screw on top of the terminal. Do not remove the screw or the components of the terminal. Place the lead wire under the retention screws and tighten the screw. It is easy also to switch out the components because they are not embedded on the board. Loosen the screws and remove the component you want to remove and replace it with the new component.

DS3800DMPC GE Mark IV Microprocessor board

The DS3800DMPC is a printed circuit board manufactured by GE for use within the Mark IV gas and steam turbine management system. The MKIV offered triple modular redundant (TMR) architecture with fault-tolerant control, the first of the Speedtronic systems with this type of two-out-of-three voting on critical controls and protection parameters. MKIV boards like the DS3800DMPC can be found in the AX Control inventory as tested, reconditioned units. We also sell liquidated (never used, like new) surplus stock.

The DS3800DMPC is a microprocessor board. It is a smaller board with only a few components on its surface. The board is drilled at least once in each corner and is marked on its surface with the GE logo and with codes like C-ESS. The top surface of the board is cut away to reveal the bottom layer at each corner.

Board components on the DS3800DMPC include two resistor network arrays, metal film resistors, capacitors made from polyester vinyl material and from ceramic material, jumper switches, and thirteen integrated circuits, including oscillating chips. The board has two connectors. One of these is a right-angled cable connector on the top edge marked 218A4637P5, and the other is a ribbon connector on the bottom edge. This is labeled 278A4702P5A. This connector is typically used to communicate with a DS3800HMPF board when the DS3800DMPC is installed as an auxiliary above that board.

For additional information about installation techniques, handling, or maintenance, please refer to publications from GE like manuals or user guides.

To achieve satisfactory results, you must install the drive on a wall or other vertical space that enables the drive to run in a cool environment. Normally the drive operates surrounded by other heat generating devices and so planning is important. There are severals ways that the room can be kept cool, despite the presence of many heat generating devices. Often fans are installed in the room which can be very helpful. The fans allow the air to move over the heated components and allow the air to circulate freely. If you choose to install fans, make sure they are in good working order and you have enough to move air around the equipment. Install industrial fans that mount on the walls so that they are not a trip hazard and can move air from the ceiling where the hot air accumulates.

Another method of keeping the room cool is using hoods that collect hot air above the equipment and exhaust it from the room. While very effective, hoods require ductwork be installed to exhaust the hot air and once installed, the equipment must remain under the hoods. However, they are also useful if dust and hazardous chemicals are also vented by the equipment. The dust and chemical are vented out of the room along with the heat.

The replacement board comes in a sealed static protective bag. It is best practice to keep the bag sealed and in the shipping box until you need it. Wear a wrist strap and slice open the end of the bag to open it. It is best practice to slice it open so that the bag can be reused. Remove the board from the bag with 2 hands and hold the board by the edges only. Never hold the board with one hand so that the components are bent, damaged, or torn off the board. This can easily happen if you put pressure on the components while you hold the board with your fingers on the components.

Place the board on top of static sensitive bag and place the old board next to it. The replacement board comes without EPROMs and it is a quick procedure to move the modules from the old board to the replacement.

The jumpers are one method for the installer to configure the board. Before the board is installed from the factory, the technician must review the information about the jumpers provided in the printed material. It describes each jumper and how moving the jumper will change how the board will process information when it is installed. Each jumper is assigned an ID that is visible on surface of the board. The ID begins with the letter J. The ID is suffixed with a unique number. You can read the information about each jumper in the instructions and find the jumper on the board using the jumper ID.

The jumpers all have 3 pins and are designed to cover 2 of the pins. The jumper can cover pins 1 and 2 for one setting. The jumper can cover pins 2 and 3 for the other setting. The information about the jumper in the written material will describe each option. When the board is manufactured and tested at the factory, the board is set with the jumpers in the default positions. The default is often the jumper position that is most common. To move the jumper from the default position, use your thumb and one finger to lift up on the jumper. Then align the jumper over the new position and slide it completely over the 2 pins.

The EPROM modules contain the configuration parameters that control the operation of the drive. When the drive comes from the factory a basic set of parameters are provided. The initial instructions can be edited to create the configuration parameters you want to apply to the drive. There are 2 ways to edit the parameters. One method is using the control panel on the drive. It is typically used by the operator for making small edits to the configuration. The 2-line display only displays a small portion of the parameters and so makes navigation difficult. Also the keys on the keypad allow limited function.

To create a large or complicated set of parameters, use a laptop that has on it a full-featured editing application. The editing program is available for download. Obtain a serial cable and connect it from the drive to the rear serial connector on the laptop. Make sure it fits the connector on both ends. The control panel is a menu-driven user interface that gives you access to initiate a download function. It will download the configuration to the laptop and when completed successfully it will display a message on the control panel display. The editing program features the ability to search for terms, copy, delete, and paste commands and text. Once complete, you can upload the parameters to the drive.

The GE Power Regulator Board DS3800DOAA features 6 trimmer resistors and 29 single-pin connectors. The GE Power Regulator Board DS3800DOAA also is populated with 20 terminals for attaching components.

The 29 single-pin connectors enable the installer to connect cables that transmit signals from the board to other boards in the drive. Other cables enable the board to receive signals from other boards in the drive. The board receives signals and processes the information before sending it on to other boards for further processing. In this manner, the signals are processed by multiple boards.

The 29 single-pin cables create some issues to consider when you install the board in the drive. The potential exists for a maximum of 29 single cables to be connected to the board. This many cables can block cool air from flowing through the interior of the drive. This can cause the temperature in the interior of the drive to rise above a predetermined threshold and automatically shutdown the drive.

Use good cable routing practices to prevent heat from building up. First, bundle the cables together and route them along the side of the drive interior. Use a port on the top of the drive to route the cables out of the drive. It is also important to separate the power cables and the signal cables. The power cables generate signals that can interfere with the signal cables. This degrades the signals and leads to processing errors. The more voltage carried in the power cables, the farther apart the power and signal cables must be.

The single-pin connectors can be used to connect 1 cable with a male pin connector attached to the end of it to the connector on the board. When you connect the cable, first identify the connector you want to connect the cable to. Each connector has an ID printed on the circuit board. The IDs are a numeric value ranging from 1 to 29. Align the male pin with the connector on the board and insert it until it is firmly attached. The information supplied with the board from the factory describes the purpose of each single-pin connector. Use that information to plan which cable you want to connect to the board.

Because of the high number of cables attached to the board, cable routing becomes a concern for a number of reasons. The cables attached to the single-pin connectors are signal cables which are sensitive to interference from power cables. Both types of cables are present in the board but they must be kept separated. To do this, the power cables must exit the drive along the side of the drive cabinet. The signal cables must be routed along the side of the drive and exit along the top of the drive. Also bundle the signal cables together and plan the routing so that they do not block the free flow of air.

The embedded resistors are installed at the factory and cannot be removed. The resistors have IDs assigned to them. The IDs are R27, R31, R97, and R101. The resistors are different ratings and they contribute to the processing performed by the board. When you install the board for the first time it is important to configure the board to process as required for the installation. One configuration task is to set the trimmer resistors. The trimmer resistors are equipped with a small screw that enables a technician to adjust the performance of the components. A small screwdriver and a testing device are required. The purpose of each trimmer resistor is described in the information supplied with the board. Use it to select the trimmer resistor you want to configure. While the tester is registering performance of the trimmer resistor, turn the small screw to adjust the signal output of the trimmer resistor. The trimmer resistor is also referred to as a trimpot, which is shortened version of trimmer potentiometer.

Another method of configuring the board is to add components on the terminals. You can add resistors, capacitors, and other components to change the signal processing performed by the board. Only a trained service technician can add or remove components because of the testing equipment you must have and the knowledge required to understand how the components change the processing output.

The methods of determining if the board is defective or experiencing intermittent errors is limited because of the lack of test points or indicator LEDs that are helpful as initial troubleshooting steps. If a board is populated with test points, a tester device can be used to ascertain the performance of individual circuits. If a circuit is found to be defective, in some cases the circuit can be repaired and the board reinstalled in the drive. If all circuits are working as normal, you can use the information to eliminate the board from consideration as the source of processing problems.

However, the GE Circuit Board DS3800DOCA1A can be evaluated using the diagnostic tools available on the drive. The diagnostic tools give a complete report on the processing performed on the board. It also provides a report on the activity of the moving parts in the drive. This includes the amount of time the motor has been used, and the load to which the motor has been subjected. Also reported is a history of all errors and warnings reported on the drive. Trip conditions are also included in the activity report. A trip condition is a serious condition that causes the drive to shutdown automatically. For example, if the drive becomes too hot or rises above a threshold, it automatically shuts down. This is also included in the diagnostic report.

The fuses on the board are designed to protect the multiple circuits from being damaged if an over voltage condition arises on the board. If too much current is allowed to be present in the board, the components might be damaged or the current might enter other boards or components in the drive. The fuses are rated with an amperage over which the fuses blow. This means the current melts the element inside the fuse and it stops the current from entering the circuit. The circuits stops processing. The rating means that current below the rating will allow the circuit to remain functional. So, to keep the circuit functional and protect the board from harmful amperage, only replace the fuses with identical fuses with the same rating. The fuses have IDs assigned to them that are printed on the surface of the board. FU1, FU2, FU3, FU4, FU5, and FU6 are the IDs you will find on the board. You will find the IDs printed on the board.

It is best practice to keep on hand a supply of replacement fuses so that downtime for the drive is limited. To replace a fuse, use one hand to remove 1 end of the fuse from the connector on the board. Then remove the other end of the fuse from the connector.

The single jumper on the board has an ID. The ID is J1 and it enables the installer to tailor the processing performed by the GE Turbine Control Board DS3800DPSS1B1B. To learn how the jumper can configure the board, refer to the printed information supplied with the board when you received it from the factory. You received in the carton information about the warranty, about contacting customer support, other flyers and updates, and a booklet about installation of the board. Included in the booklet is a description of the jumper (J1). The jumper has 2 supported positions and each position causes the board to be configured differently. The board arrives from the factory with the jumper in the default position. This is defined by the factory and is typically the most common configuration setting. The jumper covers 2 of the 3 pins that make up the jumper. The jumper is fitted over pins 1 and 2 or over pins 2 and 3. Contact is made between the 2 pins and the board processes the resulting signal to configure the board.

Another way to tailor the board is to add components to the terminals. This changes the processing of the board. However, due to the technical knowledge required to gain the processing results, only qualified individuals can add or remove components from the terminals.

The GE Turbine Control Board DS3800DPSS1C1C has fuses as protection against an over voltage condition. Each of the fuses provides protection to a circuit on the board. The fuse protects the components that are part of the circuit. If you have reason to think that a processing function provided by the board has stopped functioning, you can begin troubleshooting by viewing the board and checking the fuses to see if the elements in the fuses are intact. If the elements are broken it means the fuse is blown and that the function provided by the circuit has ceased to function.

If you see a blown fuse, remove the board from the drive and place the board on a level surface with a static protective bag under the board. Wear a wrist to give the static on your person and on the board a grounded surface to drain to. This can be a metal chair leg or a metal support on a desk. Without a grounded surface to drain the static, the static builds up and can damage components on the board.

Remove the blown fuse and replace it with an identical fuse. Make sure the fuse has the same amperage rating. Have on hand a supply of the same fuses the board uses so that the board can quickly be repaired.

The GE Circuit Board DS3800DSFC is 2 inches in height and 3 inches in length. The board features 1 trimmer resistor, multiple capacitors, and 5 jumpers. The GE Circuit Board DS3800DSFC also is populated with 2 single-pin connectors and 10 resistors embedded on the board.

The single trimmer resistor enables a qualified individual to adjust the components to the exact needs of the drive. The trimmer resistor is sometimes referred to as a trimpot because the trimmer resistor is a potentiometer. The small screw is used to adjust the component. Use a test device that is calibrated for the task and as you turn the screw, refer to the tester until you adjust the trimmer to the requirements of the drive. Once it is set, you can use a clear glue or other agent to fix the screw in place. Use a glue or other substance that can be easily removed, in case further adjustments are required.

The capacitors also require special consideration. The capacitors serve the purpose of storing high voltage current and releasing it as required. This cycle is repeated during normal processing without any safety concerns to the operator or the drive. However, if you remove the board, there is the potential that the capacitors have stored high-voltage current. If that is the case, the technician can be harmed by an electric shock if the board is touched. All that is required is to wait 30 seconds while the high-voltage current exits the capacitors. This happens without intervention by the technician.

The interior of the drive is designed for multiple boards to be installed. The drive is designed with multiple spaces in which to install the GE Circuit Board DS3800DSFC1A1A. The board is engineered with 1 hole in each corner that will align with matching holes in the board rack in which the board is installed. Use a screwdriver to insert the screws in each corner and tighten them to provide a secure installation. If you overtighten the screws it might damage the board or allow the screws to pass through the board material.

Before you install the board, the technician must decide if further adjustment is needed to be made to the trimmer resistor. Use a tester to measure the performance of the resistor trimmer and adjust it, if needed. If necessary, you can install the board and check the performance of the drive and if needed, you can remove the board and adjust the component. Once you have adjusted it, apply a small amount of a clear glue that will dry and prevent further adjustment of the screw. Only use an agent that can be peeled off and not damage the trimmer resistor.

Plug a cable into the single-pin connector, if necessary. To connect the cable align the cable with the connector and slide it into place.

The GE Speedtronic Circuit Board DS3800DSQD is also populated with an erasable programmable read-only memory (EPROM) module. Stored on the module are the instructions and firmware code used to control the processing in the drive. The EPROM module can be removed if required. The EPROM module is attached to an EPROM socket that is embedded on the board. To remove the module, locate the space on each end of the module between the socket and the module. Insert a screwdriver in the space and pry the module off the socket. Move to the other side of the socket and repeat the steps to remove the module.

You must perform this procedure while wearing a wrist strap. This is because the module is sensitive to static and the contents of the module can be compromised or made unreadable by static build up. Your person and the module can store static and the wrist strap provides a route for the static to drain to a grounded object. The grounded object might be a metal support, a metal chair leg, or a metal bench. You connect the wrist strap to the grounded object by attaching a built-in clip found on the end of the wrist strap. Some wrist straps are supplied with a connector on the end that attaches to a matching port on a workbench.

The drive is designed to operate within a range of temperatures and if the temperature inside the drive is above the range the drive will shutdown without operator intervention. Hot conditions can lead to component failure or intermittent errors. It can also lead to a fire hazard.

This is one of several trip conditions that can occur. A trip condition can also be an over voltage condition. This occurs when the voltage entering a circuit is above a threshold. Over voltage can damage components. It can also cause a fire or cause component failure. Another condition that leads to a trip condition is drive overload. This might indicate a problem with the installation or that the drive is underpowered for the work load. Early component failure can occur if the motor in overloaded. It can result in excessive heat and fire.

If a trip condition occurs it is best practice to not restart the drive until the root cause of the failure is understood. For example, you might find that the drive air vents are blocked by cables or that the drive is installed too close to other devices. In that case, move the drive away from other equipment or make more open space by removing heat generating equipment from the room.

The IDs of the jumpers are prefixed with a 1 position numeric value. Following the numeric value is a 1 or 2 position alphabetic value. For example, some of the jumper IDs are 1C, 1S, 1RA, 2RA, 3RA, and 3B. You can use the IDs to reference the installation instructions that came with the board to gain knowledge about the purpose and function of each jumper. You can learn which jumper position is appropriate for the drive. If you find that you must move a jumper, use your thumb and 1 finger to lift up on the jumper and remove it from the pins. Center the jumper over the pins you want to cover and gently insert it over the pins. Do not use force because you might bend the pins or break them off the board.

The 34-pin ribbon cable is approximately 7-inches in length. One end is attached to the board while to other end is a 34-pin connector. It attaches to a connector near the location where the board is installed. There are some considerations to keep in mind to prevent damage to the ribbon cable. When you disconnect the ribbon cable, use one hand to hold the connector and gently remove it from the connector in the drive interior. Never tug the cable free from the drive connector because it can damage the cable.

The ribbon cable provides the means by which the board receives signals from other boards in the drive. It also enables the board to send signals to other boards. The drive is populated with multiple boards that perform the processing for the drive. Signals are received by each board for processing. Then, after processing, the signals are sent to other boards for further processing. The 34-pin ribbon cable also provides the current required to power the board. The 34-pin ribbon cable is easily damaged so it requires some special consideration.

The plastic connector attached to the end of the ribbon cable contains the 34 separate strands of wire but they are easily disconnected from the connector. To avoid damage, always disconnect the ribbon cable by holding the plastic connector and not the ribbon cable. Carefully pull it out without putting stress on the cable.

This is also true when you remove the board. Do not tug the cable out of the connector by pulling on the board. When you attach the ribbon cable, also use best practices. Align the connector and use your thumb and 1 finger to press it into to place. Visually inspect it to find space between the connectors. If you find space, press the connectors again until the ribbon cable is fully seated.

The IDs of the trimmer resistors are R1, R2, and R3. When the board is delivered from the factory the trimmer resistors are set at a standard setting that is used by most installations. However, you might find that further configuration is required to achieve the processing you require. If that is the case, you must remove the board from the drive and place it on a clean flat surface. Only a qualified technician can adjust the settings of the trimmer resistors. The trimmer resistor is also called a trimpot because it is potentiometer. The technician must have a full-function tester on hand with probes that are designed for use with the tester.

The technician must refer to the specifications sheet for the board to understand which circuits the trimmer pots are part of. Use the small screw on the trimmer pot to adjust the resistance. When you are satisfied, it is a best practice to drop some clear glue or other agent on the screws to prevent the screws from being turned again. Also, choose a glue that can be easily peeled off if more adjustment is needed.

Reconnect the single-pin cables to the connector on the board. Bundle them together and route them to avoid blocking the airflow.

Due to the large number of single-pin connectors it is important that you attach the cables to the right connectors. The single-pin connectors have IDs that consist of 1 or 2 digit numeric values. Use the description of the single-pin connectors located in the installation instructions. Be sure to use the IDs to identify the right connector to attach a cable. When all the cables are attached, bundle them together and route them along the side of the drive interior. If any power cables are nearby, route them away from the signal cables. This reduces the opportunity for interference from the power cables.

The DS3800DVRC is a turbine regulator circuit board by General Electric. The DS3800DVRC is a circuit board featured in the Speedtronic Mark IV Series. The regulator boards main function is to prevent the turbine's system from experiencing energy spikes due to power surges. The DS3800DVRC accomplishes this with a variety of detailed parts. There are small resistors around eighty on this board. These resistors have a series of different color band markings. These markings are to show the number of ohms that particular resistor can handle at any given time. The board also features variable resistors or Potentiometers. There are three on this board. They can be identified by the black knobs used to adjust them. Each knob also has a tiny white arrow on top. Each variable resistor can be adjusted individually to allow a certain amount of current or energy flow across the board. Each knob is labeled zero through one-hundred, with small hash marks that indicate ten-degree intervals. The DS3800DVRC board also has ten "power resistors". These resistors are different sizes ranging from small to large. Their purpose is to hold and disperse of high power energy, like the type of jolt the system would get during a power surge. The brains of the operation though are stored in the five small chips on the board called EEPROMs. These chips hold all the programming to tell the board what to do and when to do it. These EEPROMs come preprogrammed for the boards' purpose and cannot be changed. If additional programming is required a sixth EEPROM may be added. This board features a section set aside for just that reason. This spot is labeled "SPARE" and has all the required marking to hook it up and have the current flow to it.

The DS3800DVRC1A is a regulator style circuit board for turbines. The DS3800DVRC1Ais featured in the Mark IV Speedtronic line up from General Electric (GE). A regulator circuit boards purpose is to prevent energy spikes by keeping a steady current or energy flow through the turbine. The DS3800DVRC1A has three Potentiometers or they are sometimes referred to as variable resistors. Each variable resistor has an easy to grab black knob. Each knob is clearly marked with the numbers zero to one-hundred. There are ten-degree increases between zero to one hundred to easily get the current flow you require with a simple turn. There are also little arrows on the knobs for easy identification. Once the current flow is adjusted the board relies on the five EEPROM devices on the board. These EEPROM old the programs for the board to function. These devices, however, cannot be reprogrammed. If more programming is required there is a section labeled "SPARE" on the board where an addition EEPROM may be installed. This section already has current point around it so an EEPROM can easily be installed. The parts of the board that make it a regulator are called resistors. There are two types of resistors on this board. The first type of resistor is small but numerous in number. There are around seventy-six or so on this particular board. These smaller resistors are banded with a few different colors. These colors correspond with a code to left the operator know how many ohms each resistor can withstand. The second type of resistors is called "power resistors". These power resistors vary in size from small to large and handle high power energy that may flow through the board during an energy spike.

The DS3800DVRC1A1 is a very intricately designed board with various parts. The most vital components on this board are the metal power resistors that disperse high power energy. There are twelve power resistors all varying sizes. The DS3800DVRC1A1 also has around seventy-five small resistors. They are a reddish color and each one has a color band like marking. Each band on the resistors is a color based code to calculate the number of ohms that can be passed through each resistor. The DS3800DVRC1A1 is considered a "daughter" board which means it attached to a larger circuit board to function properly. In order for easy installation, the DS3800DVRC1A1 has anchors in each corner, and a wiring harness to allow for communication between boards. The programming of the board is stored in five EEPROMs. These EEPROMs hold all the functional programming the board will need. These units are not capable of being re-programmed. There is a small section on the board where another EEPROM can be installed if needed. This spot on the board is clearly labeled "SPARE" and has the appropriate connection points around it.

The DS3800DVRC1A1 also allows the worker to control how much energy or current flows across the board at one time. In order for this to be accomplished the DS3800DVRC1A1 has three knobs on its face. These knobs are known as variable resistors or sometimes call Potentiometers. These variable resistors each have a range printed on the knobs of zero to one-hundred, (with ten-degree increases in between). The knobs also have a tiny white arrow on top of each one. In order to adjust the current or energy flow, all the worker needs to do is turn each knob to the degree they need it.

The LEDs indicate activity is taking place in different circuits on the board. They provide a quick and easy way for the drive operator to monitor the condition of the board. If the LEDs are flashing or staying lit for a short period of time, the operator will know that the board is in a good condition. If the LEDs fail to light, it provides an indication that the board is experiencing a problem If that is the case, several means of troubleshooting and resolving issues are available.

If the LEDs have stopped flashing and you suspect a problem, a qualified operator can switch the reset toggle switch to restart the board. The reset button doesn’t remove current from the board. Instead, it forces the board to restart processing. Often, if signals to the board are interfered with by high-voltage electricity, the restart process enables the signals to restart and any problems are resolved. However, only a qualified operator or servicer should use the restart switch. This is because using the switch requires the individual to reach into the drive while high-voltage current is present in the board. This exposes the servicer or operator to hazardous conditions that can lead to electric shock or burn.

The 10 jumpers that populate the board are assigned unique IDs. Each jumper is used to configure a different segment of the processing performed by the board. And the purpose of the jumpers is explained in the printed information supplied by the factory. The information is supplied to you with the original board and is found in the shipping carton. Use the description to understand the purpose of the jumpers and then find the jumper to change by locating the jumper with the same ID on the board.

The 3-pin jumpers are designed so that 2 of the pins are covered by the jumper and 1 pin is not covered. The jumper creates a contact between the 2 covered jumpers and this creates a signal that instructs the board to configure the board. Cover the pins 1 and 2 or pins 2 and 3 with the jumper. The factory defines a default setting for the jumpers, which is the settings for the jumper as it is delivered from the factory.

Best practice is to record the jumper settings for the board and keep the information in a safe place. When you replace the board, set the jumpers on the replacement board to match the defective board.

The ribbon cable is the means by which the board receives signals from other boards in the drive. It is also the means by which the board transmits signals to other boards. The ribbon cable also supplies electric current to the board. To prevent damage to the ribbon cable it is important to follow some specific guidelines. The ribbon cable is permanently attached to the board and the cable is 7-inches in length. The ribbon cable is attached to a connector that you plug into a matching connector in the interior of the board. Handle the connector gently because the 20 fine strands of wire that comprise the cable are easy to damage. Align it with the connector in the drive and press it into the connector. Inspect it for space between the connectors. If you see open space, press the two connectors together to ensure the connectors are fully seated.

When you replace the board, first disconnect the ribbon cable before you remove the board. It is important to prevent the ribbon cable from being forcefully tugged. Use 1 hand to pull the ribbon cable connector from the matching connector in the interior of the drive. Then, remove the GE Generator Regulator Board DS3800DXRA1C1C from the drive.

Before the technician can install or service the GE Circuit Board DS3800HACA1A1A it is important that the surrounding area around the drive is inspected for hazards. Look for moisture on the floor and make sure you dry the floor completely before proceeding. If the moisture is caused by condensation from humid conditions in the room, you might have to install dehumidifiers to remove the moisture from the air. Moisture is hazardous because it conducts electricity. Also inspect the area for 2-prong electrical cords and remove them from the aera. They are also a hazard because of the risk of shock and electric burns.

Finally, inspect the area for emergency shut off devices. Make sure they are in good working order. Also make sure they are near the drive and are clearly visible. Finally make sure all servicers know how to operate them. You should always have 2 servicers on site when installing or servicing a drive. The drives are high-voltage devices and a serious injury can happen at any time. If the servicer is alone, emergency aid might be delayed. But if another servicer is on site, assistance can be provided quickly and without delay.

Understand that the drive receives electrical power from multiple sources and that you must shut off all power before you begin servicing the drive.

The GE Turbine Control Board DS3800HACB features multiple pins that are connected through fine wires wrapped around the pins. The GE Turbine Control Board DS3800HACB also is populated with 11 jumpers for configuring the board and 1 20-pin connector.

The GE Turbine Control Board DS3800HACB is engineered with features to make it easy to install in the drive and remove from the drive. The board slides into the board rack in the interior of the drive. The modular connectors at the bottom of the board align automatically with the connectors in the drive and make a secure connection. Retention levers are on the top of the board and they secure the board in the rack.

1 20-pin connector is located on the top edge of the board and you can attach a 20-pin ribbon cable to it after the board is installed. When you plan to remove the board, first disconnect the 20-pin ribbon cable and move the cable out of the way. Avoid tugging on the ribbon cable while it is attached to the board. This can damage the connector and disconnect the wires from the connector on the end of the ribbon cable.

The 11 jumpers are useful for configuring the board for your specific requirements. The jumpers each have an ID. Some of the jumper IDs are RST1, RST2, FRZ1, and WRD3. When you replace the board use the same jumper setting on the replacement board as were applied to the old board.

When the board is installed in the rack, the bottom edge is attached to the module connector at the rear of the board rack. The board is populated with a module connector that fits into the modular connector in the drive. When the retention levers are closed, the retention connectors are fully seated and the board receives power and signals through the module connector. Some of the signals are received by the board through the modular connector. They are processed by the board and prepared to be sent to other boards in the drive. Other signals are transmitted from the modular connector. When you open the retention latches and pull out the board the modular connectors pull apart and the connections are lost.

The 20-pin connector is located on the top edge of the board between the retention levers. If you plan to connect a 20-pin ribbon cable, first install the board in the rack and close the retention latches. Then, plug the connector into the 20-pin connector. When you remove the board, before you open the retention latches, use 1 hand to unplug the ribbon cable and move it away from the board. The ribbon cable is easy to break by putting strain on the connector. The fine wires that attach the connector to the cable are fragile.

The fine wires wrapped around the pins enable signals to be routed to different locations on the board for processing. A qualified servicer or installer can add or remove fine wires to alter the signal routing. Only a qualified technician will have the training to understand how to obtain a specific result from adding wires between the pins. Use the configuration instructions available with the original board to read a description of the pins and how adding a wire can change the processing.

To add a wire, use a sharp knife to open the sealed bag that contains the board. Hold the board from the edges to remove it from the bag. Do not press down on any pins or components when you hold the board. This might bend pins or break them off the board. You must also prevent static buildup.

This requires you to obtain a wrist strap. 1 end of the wrist strap is worn around your wrist. The wrist strap terminates on the other end with a clip that you attach to a grounded metal surface. This surface can be a metal support on a desk or a metal leg on a stool. Some wrist straps end instead with a plug that attaches to a purpose made connector.

The decoder/demultiplexer processes signals on the board and combines several signals into 1 signal for transmission. The decoder/demultiplexer cannot be configured.

The jumpers are 1 means of configuring the board. Best practice is to configure the board before you install it in the drive. The qualified installer must consult with the engineers at the site and review the configuration options available with the jumpers. The jumpers come from the factory set at the default positions. These are typically the most commonly used configuration settings. Also, included with the board is a set of configuration instructions that detail the jumpers and how moving the pins changes how the board behaves.

Once the installer has consulted with the operators and engineers, it is easy to move the jumpers. Just before you plan to move the jumpers and install the board, open the static-protective bag and slide out the board. Place the board on top of the bag. Then, locate the jumpers to move by referring to the jumper IDs. The jumper identifiers begin with the letter J. Use your thumb and 1 finger to pull up on the jumper to remove it. Alternatively, use a small set of pliers or other instrument to pick up the jumper. Slide it over the pins you want to cover.

Some of the multiple pins on the board are attached to each other with fine wires. The fine wires route signals between the pins to obtain a specific processing result. However, when you install the board for use in the drive, a technician or installer can add, remove, and change the position of the wires. Only a qualified individual should attempt to move the wires. This is to assure that the results are appropriate for the site and what the engineers and operators intended. If rework is needed, it will result in more downtime for the drive and added installation expense.

The wires should only be moved when power is removed from the board and the board is placed on a static-protective surface. The details about the pins and how connecting specific pins together can change signal routing are provided by the factory in the hard-copy installation instruction included in the shipping carton. The drive operators and engineers and other knowledgeable individuals at the site should direct the technician in how best to change the wiring of the pins.

Further configuration can be made to the board by using the 8 jumpers that populate the board. The decoder/demultiplexer cannot be configured. It combines signals before they are transmitted to other boards in the drive.

The GE Regulator Board DS3800HAFA also is populated with 11 jumpers, and 4 trimmer resistor components. The board also has 1 20-pin connector and 1 34-pin connector.

The trimmer resistors are resistors that can be adjusted. For that reason they are called potentiometers. The trimmer resistors are sometimes called trimpots. The 4 trimpots on the board have a small screws that a qualified technician can use to adjust the resistance or voltage. Only a qualified technician has the tools and knowledge to adjust the trimpots for the specific results the site requires. Each trimpot is part of a specific circuit in the board so it is important to adjust the right trimpot for the desired result.

The technician must have a tester that is calibrated for the task and the settings on the front of the tester must be appropriate, also. Use a small screwdriver to adjust the trimpot as you monitor the tester and stop adjusting when the appropriate reading is achieved. In some circumstances a small amount of clear glue or other agent is dropped on the screw and allowed to harden. This prevents the screw from accidentally moving. However, the glue can be peeled off if further adjustments are required.

The board is also populated with a 800 vdc capacitor. When you remove the board allow 30 seconds for the current to leave the capacitor before you touch the board. A serious shock can occur otherwise.

The jumpers are assigned identifiers that are prefixed with 1 letter. Following the prefix is a numeric value. The prefix for all jumpers is the letter J and the numeric value is unique for all jumpers. For example, some of the jumper IDs are J1, J2, and J3. The jumper IDs are viewable on the surface of the board.

Because the board is populated with multiple components and can have many cables connected to it, it is important that it have cool air available to freely flow over it. This cool air carries away the heat that can build up on the board. When the installer plans for installation of the board, it must be kept in mind that air flow must be available on all sides of the drive. That is, the top, bottom, and both sides must have space for air to freely flow around the drive. To cool the interior of the drive, cool air must be available to enter the bottom of the drive and exit the top of the drive through the air vents.

However, the ribbon cables can block the flow of air if not routed properly. Don’t route the cables in front of the air vents or around the components on the board.

Under some conditions, the resistors that populate the board must be adjusted to make the board more compatible for the drive configuration. That is, compatible with the combination of boards and other devices installed in the drive. If that is the case, the trimmer resistors on the board are useful because they enable a technician to adjust the resistance. The technician should consult with the site operators and engineers to determine the processing needs of the site. Then, use a testing device to gauge the signal of the circuit that you want to adjust. Use a screwdriver to adjust the trimmer resistor. When the signal is adjusted, an optional step is to drop a liquid on the screw that hardens and prevents the screw from accidentally turning. Use a liquid that will not harm the trimmer resistor and can be peeled off if more adjustment is needed. This might happen if the board is removed from 1 drive and installed in another drive.

The trimmer resistors are also known as trimpots because they serve as potentiometers. When the board arrives from the factory, the trimpots are adjusted for a standard resistance that serves the purposes of most drives. The adjustment is made at the factory during product testing.

The best practice is to connect the 20-pin and 34-pin ribbon cables after the board is installed in the board rack. This is because the ribbon cables can easily be broken if stress is placed on the ribbon cable and the connector on the end of the ribbon cable. The fine strands of wire that connect the cable to the connector are easily pulled from the connector. The signal is lost for any connection that is damaged. If the board is secure in the rack, the ribbon cables will not be subject to stress from moving the board.

Also, the ribbon cables must be routed properly to avoid interference from power cables in the drive. Route the ribbon cables along 1 side of the drive and route any power cables along the other side of the drive. Limit the exposure of the signal cables to the power cables as much as possible.

Also, the servicer will use a testing device to monitor the circuit and at the same time turn the screw of the trimpot. When the target resistance is obtained, you can drop a substance over the screw to prevent further adjustment. The liquid hardens. If the board is remove from the drive and installed in another drive, the substance can be peeled off so that the trimpots can be adjusted again.

The ribbon cables are connected to the 34-pin connectors on the front of the board. Refrain from tugging the ribbon cable to remove the connector. This can damage the ribbon cable and disconnect the signal wires from the connector.

The GE Regulator Board DS3800HAIC1C1B is designed to provide defect free operation in the drive. However, the drive can experience trip conditions that cause the drive to shutdown automatically. The trip conditions protect the drive from damage. One trip condition is caused by an overload condition. That is, the motor and moving parts are performing above the designed workload. In that case, the drive will shutdown automatically to protect the drive from damage. Before you restart the drive, you might troubleshoot the cause of the shutdown. Either reduce the workload or install another drive that can perform the operation within the designed work parameters.

Another trip condition is caused by current overload. This can result in damage to the components and can also lead to fire or injury if the condition is allowed to continue. It is best practice to ascertain the cause of the trip condition before you restart the drive and you might consult with an electrician or an engineer, if necessary. Another trip condition is caused by the interior temperature of the drive rising above a predetermined threshold. Check that the air vents on the bottom and top of the drive are clear and that they are not blocked by cables.

The GE Regulator Board DS3800HAIC1D1B also is populated with 9 jumpers, and 2 trimmer resistor components. The board also has 1 20-pin connector and several test points.

The trimmer resistors are embedded on the board to enable a servicer or technician to configure the resistors to perform as required for the drive. When the board is delivered from the factory, the trimmer resistors are set for a standard environment. However, if you see the need for adjustment, the board can be removed and the resistors can be adjusted. Only a certified technician should attempt to adjust the trimmer resistors because of the opportunity to damage the board or cause suboptimal performance. The trimpots are adjusted by turning a small screw on the top of the component. The trimmer resistors are sometimes called trimpots. This is due to the fact that they are potentiometers.

Once the servicer has set the trimpots to provide the best performance, you must prevent the screw from being disturbed. To do that, it is sometimes best to drop a small amount of a liquid that hardens over the screws. The liquid when dry can be peeled off the trimpot if more adjustment is required. This might be the case if the board is installed in another drive or if other components change the configuration of the drive.

The GE Regulator Board DS3800HAIC1D1C also is populated with 9 jumpers, and 2 trimmer resistor components. The board also has 1 20-pin connector and several test points.

The modular connector is located on the bottom of the board and it is designed to attach to a matching connector at the rear of the board rack. When attached, the connectors provide the current required to power the board. The modular connectors also enable the board to receive signals transmitted by other boards. The board transmits signals through the modular connectors too. It is vital that the connectors are fully seated so that all power and signals connections are complete. To do that, use 2 hands to hold the board by the sides and align it with the board rack. Make sure it doesn’t knock against any components on the board while you slide it into the rack. Also keep the board from scraping against the rack. Use your thumbs to gently press the board into the modular connector and the retention levers will be in position to secure the board. Press the retention levers down to lock the board in the rack. At this point the modular connectors are fully seated and the power and signal connection are complete.

When the board is installed, you can connect any ribbon cables to the 2 20-pin connectors. Press the connector on the ribbon cable into the connector on the board.

Each jumper is comprised of 3 pins that are embedded on the board. The pins are easily bent so care must be taken when you carry the board or insert the plastic jumper over the pins. When you carry the board in your hands, only touch the sides edges of the board. This will protect the pins from accidental damage from bending. When you insert a jumper over the pins, align the jumper over the pins and gently slide the jumper over the pins. If you feel resistance, don’t force the jumper. Instead, make sure the jumper is aligned over the pins.

The 3 pins that comprise the jumper are numbered 1, 2, and 3. When you slide the jumper over the pins it covers 2 of the 3 pins. It covers either pins 1 and 2 or pins 2 and 3. The 2 covered pins form a connection that configures the board to produce a particular result. For a description of the jumpers and the processing options, refer to the installation instructions that are shipped to the site. The instructions come in the same carton in which the board is delivered. The jumper have IDs that help you locate the jumpers on the board after reviewing the instructions.

The GE Turbine Control Board DS3800HCIB also is populated with 1 jumper, and 1 amber indicator LED. The board also has 1 20-pin connector, 1 50-pin connector, and multiple capacitors.

The capacitors on the GE Turbine Control Board DS3800HCIB have IDs that are visible on the surface of the board. They have a prefix of the letter C. The prefix is followed by a numerical value that is unique for each capacitor. C16, C19, and C28 are some of the IDs associated with the capacitors. The capacitors require some special consideration when the board is removed from the drive. The capacitors are designed to store high-voltages during normal processing. When needed, they also release the high-voltage current and this cycle of storing and releasing current is performed without hazard to the operator or other in the surrounding area. However, when the board is removed from the drive, the capacitors might still have stored some high-voltage current. This exposes the technician or others who touch the board to the risk of shock or electric burn.

However, the capacitors will release the current after power is removed from the drive in 30 seconds. In other words, the risk to the technician is eliminated if you wait 30 seconds before touching the board. After 30 seconds, open the retention levers and carefully remove the board.

The 20-pin connector and the 50-pin connector are accessible to the operator when the board is installed in the rack. The connectors are located between the retention levers and are designed so that a technician can remove or connect a cable while the board is installed in the rack. There are some considerations to keep in mind before you plan to install the ribbon cables. First, the ribbon cables can block the airflow in the interior of the drive if they are not routed properly.

The components in the drive generate heat during normal processing and if the heat is allowed to build up, the heat can lead to a shortened component lifespan and increased downtime for the drive. It can cause an overheat trip condition that causes the drive to shutdown by itself. The best way to avoid that is by allowing a source of air to enter the drive through the bottom air vents. The air is heated by the components and exits the drive through the air vents at the top of the drive. Route the cables away from the vents so that the heat does not accumulate in the drive.

The board also has 3 connectors accessible from the front of the board, and 4 trimmer resistors.

The GE Digital to Analog Output Board DS3800HCVA1F1G is populated with an erasable programmable read-only memory (EPROM) module. The module contains the instruction code and firmware that is used to control the board processing. The module is sensitive to static and so when you plan to handle the module you must take steps before hand to reduce the opportunity of static to corrupt the module. Keep the replacement board in the static protective bag until you are ready to install the board. The bag prevents static from leaving your person and entering the board. Wear a wrist strap too. The static exits your person and is drained to the grounded surface attached to the strap.

When you receive the replacement board you will find that the module socket are empty. This is because in most cases the modules from the defective board are moved to the new board.

Using the same firmware and instruction code contained on the module helps ensure that the replacement board will function the same as the old board. If new code and firmware is introduced, the board will operate differently, which might lead to operational difficulties.

The board also has 3 connectors accessible from the front of the board, and 4 trimmer resistors.

The trimmer resistors can be adjusted to change the resistance of the component. The trimmer resistors provide a means for a qualified technician to tailor the board to the exact needs of the drive. The trimmer resistors come from the factory adjusted to a standard resistance value. If you find that the processing provided by the board is in need of tailoring, remove the board from the drive, first. Place the board on a flat and sturdy surface. This might be a desk or table. The surface must be free of dust, dirt, and clutter. Have on hand a full function testing device. The testing device must be calibrated to provide exact results. Also, the probes must be designed for use with the tester and they must be in good condition. Look for missing or worn insulation.

Locate the trimmer resistor you want to adjust. The trimmer resistors are part of circuits on the board. Use a diagram of the board to determine which trimmer resistor is part of the circuit you want to tailor. The diagram is available in the product information supplied by the factory. You will find it package with the original board you receive from the factory.

The board also has 3 connectors accessible from the front of the board, and 4 trimmer resistors.

The jumpers are the primary method for a technician to configure the board to operate most effectively in a drive. The manual supplied with the board contains information about the jumpers and describes how the jumper positions can change the board processing. The jumpers have 2 positions and changing the position changes the board configuration. The jumpers have 3 pins. Change the pins that the jumper covers to change the configuration. The jumper can cover pins 1 and 2 or pins 2 and 3. When the board is manufactured, the jumpers cover the default configuration. The default is usually the standard or typical configuration. However, it can easily be changed if needed.

Use your fingers or a small set of pliers to move the jumper. Pull up on the jumper to remove it from the 2 pins it covers. Then, align it with the 2 pins you want to cover. Gently slip it over the pins. However, do not bend the pins or break them off the board.

The IDs of the jumpers are 2 or 3 position identifiers. The suffix is always the letter J. The remainder of the ID is a 1 or 2 position numerical value. The IDs are printed on the board for easy identification.

The dc to dc voltage regulators are embedded on the board and send and receive signals and voltage through the circuits on the board. However, you will notice that the components are also attached to the board with plastic zip ties. The zip ties wrap around the board and help keep the components securely attached to the board.

The dc to dc voltage regulators send and receive current and so are prone to generating heat. Because of that, the drive must be located in an environment with room air temperature. In a room with multiple drives and other heavy equipment and electrical devices, you must plan head to prevent the drive from overheating. The drive is mounted on a wall and the wall can be a source of heat. Check the wall temperature and if it seems hot to the touch, look in the room on the other side of the wall. If the room is hot, you might consider removing some equipment from the room to reduce the room temperature. Another solution is to add wall-mounted fans to remove heat from the equipment. Consider adding hoods to draw out the heat and dust from the room.

Press down of the levers to lock the board in the rack.

When the board is installed properly, the 2 LEDs are visible to the operator. They are an easy and quick method for the operator to monitor the operation of the board. The LEDs flash when the board is processing information. When the LEDs are off for an extended period of time, it indicates that the board has stopped processing or has an intermittent problem.

If that happens, it is best practice to turn off the power to the drive and wait 30 seconds for all power to exit the drive. Then, release the retention levers and pull the board slightly out of the rack. Wait several seconds and return the board to the rack and press it back into the modular connector and close the retention levers.

The board also has 3 connectors accessible from the front of the board, and 4 trimmer resistors.

The trimmer resistors are often called trimpots. This is because they have an adjustment screw and are potentiometers. The screws adjust the resistance supplied by the component. A qualified servicer can perform the adjustment. The servicer must have a full featured testing device to monitor the voltage while adjusting the screw. Once the proper adjustment is made, cover the screw with a few drops of a liquid that quickly hardens and prevents the screw from moving. The liquid does not harm the components and can be peeled off to allow a servicer to make more adjustments. This might happen if the board is installed in another drive or if additional components are added to the drive.

Never force the board into the rack or force the retention levers. If the board doesn’t easily slide into the rack, reposition the board over the modular connector and gently press down. If aligned properly, the modular connector will slide into the matching connector in the rack.

When the drive is powered on, the LEDs on the board will light for several seconds. This serves as a test to prove the LEDs are functional.

The 2 40-pin connectors are accessible by the operator when the board is installed in the drive. However, any cables attached to the connectors should only be touched if the drive has all power removed.

Removing power from the drive requires that someone familiar with the installation of the drive confirm that all power has been removed. The drive has multiple sources of current and only someone familiar with the installation will know the sources of power and how to disconnect them. Before you touch the board, use a full featured testing device to confirm that all power is removed.

Be familiar with the emergency power shut off devices associated with the drive. In case of an emergency, the shut offs can remove all power from the drive. It is important that 2 technicians are always present to service the drive. If 1 technician is experiencing an emergency, the other can call for help, shut off the power, or assist the other technician.

Before you start the installation, inspect the area around the drive for safe conditions. Make sure the floor is dry and free of oil and debris. If moisture is on the floor, clean up the water first. If moisture reoccurs, you might have to install dehumidifiers so the floor remains dry.

The GE Line Driver/Receiver Board DS3800HDRA1A1A is installed in a drive that contains high-voltage electricity and also contains a powerful electric motor and other moving parts. For this reason, it is a potentially dangerous device. Without proper consideration an individual can be exposed to electricity that can shock or burn. The motor and other moving parts can cause bodily injury. Part of the planning for installing the board must be to inspect the area around the drive and look for unsafe conditions.

The floor around the drive must be dry to the touch. Any liquid can conduct electricity and cause a shock. Dry the floor with towels or use other means to dry the floor. If condensation is the cause of the moisture, you might consider installing dehumidifiers. A floor that is constantly wet is a danger to the operators and servicers that work in the area.

Inspect the area around the drive and if you find ungrounded electric cords, remove them. They can cause a shock because they lack a ground connection. Clean any oil or grease from the floor. Oil and grease are a trip hazard and can injure operators, servicers, and technicians.

The board is populated with a modular connector on 1 end. The modular connector is designed to connect with another modular connector at the back of the board rack in the drive. The 2 modular connectors meet and provide connections for many signals and power supply connections. When the board is removed from the drive, the connections are discontinued without intervention by the servicer. That is, simply removing the board ends the signal and power connections. The modular connections facilitate command signals that are received by the board for processing. The modular connections also provide the means for the board to send command signals to other boards in the drive. During normal processing the board transmits and receives signals multiple times to control the motor and the moving parts.

On the opposite side of the board are retention levers. They fit into slots on the board rack and lock the board in the rack. They keep the board from moving to protect the components. They also maintain the connection between the modular connectors.

The GE Function Processor Board DS3800HFPC also is populated with 8 jumpers, and multiple capacitors. The board also has 1 40-pin connector that is accessible from the front of the board. It also has standoffs for attaching a daughter card.

Another component on the board is a transistor to transistor logic (TTL) device. It serves as the interface logic between integrated circuits. The erasable programmable read-only memory (EPROM) modules come preloaded from the factory with the instructions and firmware the board uses to process information. The modules are installed on a socket that is embedded on the board. The modules can be removed and replaced by a trained servicer. This is useful if the board is to be replaced. The replacement board comes without EPROM modules. The module sockets are empty. This is to enable the servicer to install the same firmware and code on the replacement board. In this way, the new board will behave the same as the defective board. The drive can quickly resume operations after the board is replaced.

However, you must understand that the firmware and code on the modules is easily corrupted by static interference. This can happen when the modules are handled or stored improperly. For example, always store the modules in a static protective bag. The bag keeps static from entering the modules. When you remove the modules, a wrist strap will drain static from your body to the grounded surface the strap is connected to.

The last step in installing the board is to connect a ribbon cable to the 40-pin connector on the board. The connector is accessible to the installer when the board is installed in the rack. The connector is located between the 2 retention levers. They secure the board in the rack and firmly connect the 2 modular connectors. 1 modular connector is embedded on the board. The other is located inside the drive at the rear of the board rack. When you insert the board in the rack, the 2 modular connectors meet and form a connection. When you lock the retention levers, the modular connectors are firmly seated.

To install a ribbon cable, hold the plastic connector at the end and leave slack in the ribbon cable. Align it with the connector on the board and press it into the connector. Look for space in the connection and press the 2 connectors together again. Pull the cable out by holding the plastic connector. If you pull out the ribbon cable by holding the ribbon cable, you might damage the ribbon cable.

Another component on the board is a transistor to transistor logic (TTL) component. It serves as the interface logic between integrated circuits.

If you have a need for additional processing, you can add a daughter card to the GE Function Processor Board DS3800HFPC1M1H. The standoffs provide a means to attach the daughter card. The daughter card has 1 hole in each corner and the standoffs fit into each hole. The power and signals connections to the daughter card are made through the connector at the rear of the daughter card. When you press the daughter card into the standoffs, the power and signal connections are made though the connector.

The retention levers eliminate the need for screws to secure the board in the rack. The screws are prone to falling into the drive. Loose screws might cause an electrical short which can lead to fire or damage to the drive. The other consideration is that the screws might become lodged in the moving parts and jamb them from moving. This might damage the moving parts or the motor by preventing them from moving properly.

Another component on the board is a transistor to transistor logic (TTL) device. It serves as the interface logic between integrated circuits. Because the board is powered with high-voltage current and features a powerful motor and other moving parts that can cause injury to operators and others in the surrounding area, it is important to use all safety considerations to service and install the board. The drive is often located in a site with dust, dirt, grease, and moisture present. This is due to the manufacturing environment. However, when a service task is being planned, it is important to clear the area and create a safe environment.

First, examine the floor and look for moisture or puddles of water. Because water is a conductor of electricity, it is safety hazard due to the risk of shock. Use rags or a wet-dry vacuum to clean up any water or other liquid. Wait until the floor is completely dry before continuing. Clear the area of any debris because it is a safety hazard. If 2-prong extension cords are in use, remove them due to the risk of shock from the ungrounded electrical current.

The board is populated with 4 LEDs that the operator can monitor during normal operation to maintain an understanding of how the board is processing. Each of the 3 red LEDs provide an indication of how the board is processing. When each red LED is flashing, it indicates when activity is occurring on the board. When the red LEDs are off, if indicates that activity is not occurring. If the red LEDs are not flashing, it might be because an error has occurred. The amber LED is lit when power is supplied to the board and the board has passed all startup diagnostic tests.

If the processing activity on the board has stopped and the red LEDs are not lit, it is best practice to troubleshoot the condition.

One troubleshooting step is to run the drive diagnostic program. The diagnostic report will provide a chronological list of the board activities. This includes all errors and warnings. Trip conditions are also listed. For example, if the interior of the drive becomes too hot, the drive will automatically shut down. This is an overheat trip condition.

DS3800HFPG1D1G Drive Control Board

The DS3800HFPG1D1G is a Mark IV board component manufactured by General Electric. The Mark IV significantly reduced downtime caused by parts failure as compared to its predecessor, the Mark II. It did this through its control architecture that features triple modular redundant voting on all protection parameters and critical controls. This type of control allows the system to enlist “two out of three voting” to bypass discrete faults and keep the overall system running. Mark IV boards are no longer actively manufactured, but they can be purchased from AX Control as reconditioned and fully tested units.

The DS3800HFPG1D1G is a Drive Control Board. This is a large circuit board with many board components. The board has two backplane connectors on its leading edge. The opposite long edge is fitted with two extractor clips and one right-angled cable connector. The center of the board also includes a single vertical pin cable connector (male.) The board is fitted with several standoffs to allow the mounting of an auxiliary board. There are two board stiffeners installed along the long dimension of the board, one along the centerline and one along the bottom edge just behind the backplane connectors.

Other board components that appear on the DS3800HFPG1D1G include twelve jumper switches, five resistor network arrays, a single amber LED indicator and a bank of red LED indicators, board-to-board pin connectors, TP test points, spare PTH, capacitors, diodes, and resistors. The board has over eighty integrated circuits; most of these ICs are marked on their top surface with their original manufacturing codes that will allow the user to look up additional information about each chip if desired. For more information about the board, including handling and installation procedures, refer to GE manuals and data sheets.

To understand the exact cause of the error, diagnostics are available on the drive. The diagnostics might be time consuming to run. This can add to the length of time the drive is down and not operating.

When the amber LED is on, the first step is to disconnect the drive from all power. This includes all dc and ac power sources. Use a full feature testing device to test for the absence of current in the drive. Remove the board partially from the board rack and wait 30 seconds. Then, return the board to the board rack. This give the control signal an opportunity to restart and return to the proper signal sequence.

In this way downtime of the whole system is minimized; instead, the system continues to run and the user is given time to diagnose and repair the issue.

The DS3800HIMA1B1B has the following specs:

drilled in three of four corners
one amber LED
small transistors (2) located near one short edge
one larger transistor, located near the opposite short edge in the top corner of the board. This transistor has a marking of LM309K and is DTL/TTL compatible.
2 AM26LS33 quad differential receivers
2 AM26ls30 dual differential circuits
2 HP69137 Dip components
1 Bicron transformer (218A4819P2)
1 capacitor 708D1 8803D 200V
1 capacitor 708A1 m/c 100v 5.0+ 10% 8942

The DS3800HIMA1B1B is built with several capacitors (including those listed,) and multiple diodes and resistors. It is worth noting some diodes are not marked with a prefix; this is noted on the edge of the board.

The GE Input Isolator Board DS3800HIOA features a hole in each corner for installing the board with screws in the drive interior. The GE Input Isolator Board DS3800HIOA also is populated with a microprocessor and multiple erasable programmable read-only (EPROM) modules. The board has 1 34-pin connector that is accessible from the front of the board. It also is populated with test points and 1 40-pin connector on the surface of the board.

The erasable programmable read-only (EPROM) modules snap into a socket that is embedded on the board. They can be removed from the socket if the board is replaced in the drive. They can also be removed if the firmware and code is updated with an updated version. Often code is not updated because once the board is installed and it successfully receives commands signals and processes the signals, the site continues to use the same version of the programming code and firmware. However, the modules are removed if the board is replaced. The board might be replaced if it is defective.

The replacement board is shipped you without EPROM modules installed and so the servicer must remove the modules from the defective board and install them on the new board. Locate 1 short end of the module socket and insert a screwdriver between the socket and the module. Twist the screwdriver and loosen 1 end of the module. Repeat the action on the other short end of the socket and place the module in a static protective bag.

The board has 1 34-pin connector that is accessible from the edge of the board. It also is populated with test points.

Because the board is populated with components that are sensitive to heat, it is important that the drive is installed in a location that is not excessively hot. The drive is installed on a wall or other surface.

When you select a location for installation, check the wall on which you want to mount the drive. If the wall is hot you can take steps to reduce the heat. Inspect the room on the other side of the wall and if it has wall-mounted equipment that generates heat, consider removing the equipment from the wall.

You can also install a hood to remove the heat from the room. Place the hood above the equipment and it will remove excessive heat and dust from the room. Also consider installing free-standing fans or wall-mounted fans. Make sure you add enough fans to remove the heat from the equipment. Another option is to mount the drive in a room with a lower temperature and less heavy equipment.

The drive will automatically power off if the interior of the drive is too hot. This protects the components from damage and prevents a fire hazard. However, it also reduces productivity and increases service costs.

The board has 1 34-pin connector that is accessible from the edge of the board. It also is populated with test points.

A ribbon cable is attached to the 34-pin connector. The 34 separate signals it carries are commands the board sends to other boards for processing. Other signals are received by the board. Those signals are processed by the board. The ribbon cable requires special consideration because it is a wide cable and can block air from moving through the drive. Proper cable routing can help maintain the airflow. Route the cable along the outside edge of the drive interior and avoid blocking air from reaching components and other boards.

The ribbon cable attaches to the board through a connector on the end of the cable. It doesn’t have a sturdy connection to the ribbon cable and can easily be pulled out of the ribbon cable or lose connections. Always maintain some slack in the ribbon cable so that the cable is not strained or pulled. Never pull the ribbon cable out by tugging the ribbon cable. Instead, hold the connector and gently remove it from the connector.

When you are connecting the ribbon cable and installing the board, protect the board from static electricity build up. Wear a wrist strap to protect the components from damage.

The GE Input Isolator Board DS3800HIOA1B1D is mounted on a wall and the installation procedure involves several steps. A mounting plate is included as the back panel of the drive. Specific mounting hardware is required to install the mounting plate. This includes bolts and other hardware, depending on the construction of the wall. You must also have the signal cables prepared for the drive. This includes networking cables and other types that will control the drive. The signal cables must be located near the drive so that the cables can be wired directly to the drive. Power supply cables must have emergency shut off devices installed near the drive. The power cable must have the voltage necessary to power the drive. Route the signal cables well away from the power cables due to the interference that can occur in the command signals. The power supply cables emit intefence that is picked by the signal cables. If proper cable routing is not possible, shielded signal cables can eliminate or greatly reduce the interference.

If you plan to use fibre optic cables, you can route them without regard to the power cables. This is because fiber optic cables cannot pickup the power cable interference.

The board has 1 34-pin connector that is accessible from the edge of the board. It also is populated with test points.

If you find that the GE Input Isolator Board DS3800HIOA1C1D is not functioning as expected, there are several troubleshooting steps you can take. You must remove all power from the board before you start. To do that, you must consult with an installer who is familiar with the installation of the drive. The installer will have knowledge of the various sources of power connected to the drive. You must understand that the drive requires several sources of power and that they must all be disconnected. If a dc power source is connected, you can remove the fuses from the power inverter to disconnect power. If ac power is connected to the drive, you can remove power by pulling a circuit breaker.

Once power is removed, it is best practice to use a full function testing device to check for the presence of power in the drive. Inspect the 4 fuses on the board and if any of them are blown, replace them. If you replace a fuse, restart the drive and check to see if full operation is restored to the board. Make sure the fuses you install in the board have the identical rating as the fuses you remove.

If the board is not operating at full capacity first inspect the fuses. Replace any that are blown. If too much power is present in the circuit or other unusual activity occurs, the fuse will blow to protect the circuit. This removes power from the circuit and the function provided by the circuit will be lost.

Another source of information is to use the test points which are located on the surface of the board. They are available for use by a qualified servicer to test the function of the board. Each test point is associated with a circuit on the board. With use of a properly calibrated testing device, the servicer can check the health of a circuit. The servicer must have knowledge of the board circuitry and the proper safety precautions. In some cases, a board can be repaired and installed in the drive.

The testing can only be performed when the board is removed from the drive. The board must be placed on static protective material. This might be a mat designed for the purpose or on a flattened static protect bag.

The GE Digital I/O Board DS3800HIOD is designed for quick installation in the drive. The board features a modular connector on 1 end and retention levers on the other end. The GE Digital I/O Board DS3800HIOD also is populated with 2 10-pin connectors and 1 40-pin connector located between the retention levers making them accessible from the front of the board. It also is populated with 6 jumpers.

The drive that the GE Digital I/O Board DS3800HIOD is installed in is designed for easy board installation. One feature is that the drive has module connectors at the rear of the board rack. The modular connector automatically connects the power and signals to the drive. This reduces the number of power and signal cables routed in the interior of the drive. One benefit is that cool air is able to flow easily through the drive and keep the components within the allowable temperature range. Another benefit is that the opportunity for connecting the wrong cable is eliminated. When you install the board, the connector on the end of the board meets the connector at the bottom of the board rack. Use your thumbs to gently press the board into the rack and simultaneously the modular connectors are pressed together. The retention levers lock the board in the rack.

The GE Digital I/O Board DS3800HIOD1G1E can be configured for use in many different environments. The configuration is performed by the installer with input provided by the site operators and engineers. The board comes from the factory with a default configuration. This is a standard configuration used in most work environments. However, the 6 jumpers can be changed to suit the specific needs of the environment. The definitions of the jumpers is included in the installation and service document included with board from the factory. Review the information and if you decide to change a jumper, place the board on a workbench or other workspace.

Wear a wrist strap and locate the jumper you want to change. The jumper IDs are prefixed with J. The prefix is followed with a numerical value. For example, J1, J2, and J3 are some jumper IDs. You use your thumb and forefinger to lift the jumper from the jumper pins. Then, gently place the jumper over the new set of pins. Work slowly so that you do not bend the pins or break them off the board.

The GE Digital I/O Board DS3800HIOD1G1G is installed in a drive that requires some specific environmental considerations. The drive has to be installed in a location that is cool and has a supply of clean air. The location has to have an adequate supply of electric power. In some environments, the installation occurs in a room with other equipment that produces heat. If that is the case, you can reduce the number of drives and other equipment in the room to reduce the heat. You can also add fans to keep the air flowing around the drive and keep heat from building up. Use high-powered industrial fans that are mounted on the walls. Make sure they are in good condition and that you install enough of them to move the air and reduce the heat build up.

If dust and dirt in the air is a problem, mount hoods over the equipment to draw away the dust and dirt. The contaminants can be exhausted from the area to keep the air clean.

The GE Digital I/O Board DS3800HIOD1H1G is sensitive to the build up of static electricity. The static enters the board when an individual walks around with the board. However, with specific measures, you can keep static from entering the board. First, the board is shipped to you in a sealed static protective package. It is best to keep the board in the sealed package until you are about to install it. Wear a static protective wrist strap to handle the board. 1 end of the strap is wrapped around your wrist or arm. The other end of the cord ends with a clip that can be attached to a metal chair, a metal post, or any other metal object. The static seeks out the grounded object and drains from your person. Other types of wrist straps end in a plug. This is meant to plug into a purpose build connector on a workbench. It provides a secure and convenient grounded surface.

If you have to move jumpers or perform other tasks on the board before installation, place it on a static protective bag.

The GE Digital I/O Board DS3800HIOD1H1H can potentially have 3 ribbon cables connected to it when it is installed in the drive. The connectors have retention clips to make sure the cable doesn’t accidently come loose. Move the retention clips out of the way when you install the ribbon cables. Then, once the ribbon cables are installed, swing the retention clips over the ribbon cables and lock them over the ribbon cables.

The ribbon cables can block air from entering the interior of the drive. This can cause the heat to build up inside the drive. If the temperature rises above a predetermined threshold, an over temperature condition will occur and the drive will automatically shut down.

Keep the ribbon cables from blocking the air vents at the top and bottom of the drive. The cool air enters the bottom of the drive and the heated air leaves the drive from the air vents at the top. Inside the drive the air removes heat from the components. Route the cables along the side of the drive and route the cables to exit through the top of the drive.

The GE LCI Contact Interface Board DS3800HIOD is designed for quick installation in the drive. The board features a modular connector on 1 end and retention levers on the other end. The GE LCI Contact Interface Board DS3800HIOD also is populated with a reset button located between the retention levers making it accessible from the front of the board. It also is populated with 8 trimmer resistor components and erasable programmable read-only memory (EPROM) modules.

The trimmer resistors are potentiometers because of the adjustment screws that are available for use on the components. When the adjustment screw is turned, it varies the resistance of the trimmer resistor. This is helpful if an adjustment will cause the board to better meet the processing requirements of the drive. The purpose of each trimmer resistor is provided in the service information provided with the board from the factory. When you open the shipping carton, you will find shipping material covering the board. Move it to 1 side and you will find the printed information. This includes contact information for customer service, warranty information, and a service and installation manual. The documment includes complete information about the trimmer resistors. This includes the circuit the components are part of, and how the adjustment will change the behavior of the board.

The technician must have a full featured testing device. Use a screwdriver to adjust the screw while monitoring the trimmer resistor performance with the testing device. Perform the adjustment on a static protective mat or on top of a flattened out static protective bag.

The trimmer resistors provide a means to configure the operation of the board to meet the specific requirements of the drive. When you install the original board from the factory, the trimmer resistors are set to a default adjustment. This means the resistors provide a standard level of signal processing. If you find that further adjustments are needed, the board can be removed from the drive and placed on a static protective surface. This might be a protective mat or a flattened static protective bag.

Use a small screwdriver to make the adjustment and use a testing device to measure the results. When complete, liquids are available to drop on the screw. The liquid hardens and prevents the screw from being accidently turned. The liquid can be peeled off the trimmer resistor and further adjustment can be made. Install the board back into the board rack and return power to the drive.

The trimmer resistors are called trimpots. The trimmer resistors are potentiometers due to the fact that the screws enable adjustment.

The drive uses high-voltage current to processing signals and to power the motor and other moving parts. For this reason only qualified technicians should attempt to service the drive. The drive poses a risk of serious electrical shock and burns. Also, the powerful motor and other moving parts can cause bodily injury.

Before the drive is serviced, the qualified individual completes an inspection of the area surrounding the drive. The floor must be completely dry with no moisture or puddles of water present. Use towels or a wet dry vacuum to dry the floor. If condensation is a constant occurrence, it might be necessary to install air conditioning units to provide the area with dry air. Use detergents to clean the floor of any oil or grease. The oil and grease can pose a trip or slip hazard to the sericers and other individuals. At least 2 servicers should be present to work on the drive. If 1 servicer is injured, the other servicer can call for help, assist the injured servicer, or use the emergency power shut offs to remove all electrical power from the drive.

The drive contains a modular connector at the end of each board rack. When you slide a board into the rack, the 2 modular connectors meet. The connectors have the same number of connectors and are designed to press into each other to make signal and power connections.

Carefully slide the board into the rack and make sure the components on the board do not scrap against the sides of the rack. The components might be damaged by rough contact with the metal rack. Press the board into the rack with your thumbs to seat the modular connectors. Open the retention levers on the board so that they are prepared to lock the board in the rack. Then close the retention levers. This locks the modular connectors together and prevents the board from moving also.

The modular connectors serve several purposes. They enable the board to receive the current to power the board. The modular connectors also provide the means for the board to receive all command signals from the other boards in the drive. The board also sends signals through the modular connectors.

Another component on the board is a transistor to transistor logic (TTL) device. It serves as the interface logic between integrated circuits. The capacitors and resistors are not configurable components of the board and they are embedded on the surface of the board. They are designed to provide a specific function used during processing. They work without any operator intervention. However, the capacitors require some consideration if the board is removed by a qualified servicer.

The drive is powered by high-voltage current that powers the powerful motor and the boards, including the GE Logic Element Board DS3800HLEA1C1B. During normal operation the high-voltage current is temporarily stored in the capacitors. The capacitors release the current and repeat the cyclical multiple times. If the board is removed the capacitor might retain some high-voltage current even if the board is removed from all power sources. This puts the servicer at a high risk of injury from electric shock or burn. A simple method exists to force the high-voltage current in the capacitors to exit and leave the capacitors harmless. After power is removed from the board, wait 30 seconds and the current will exit the capacitors without servicer intervention.

Another component on the board is a transistor to transistor logic (TTL) device. It serves as the interface logic between integrated circuits. The GE Logic Element Board DS3800HLEA1C1C is engineered for installation in a high-voltage drive. The drive is installed on a wall or other vertical surface. Before you install the drive you must prepare the electrical cables and the signal cables that you plan to connect to the drive. The drive uses multiple sources of electrical power and often an inverter is used to convert the ac power to dc power. The drive uses the dc power to drive the motor and the processing components. An important requirement is to install emergency shut off devices on all electrical supplies. The shut off devices must be installed near the drive and be easily reached by a servicer or other technician.

Route the signal cables separately from the power cables. This is to reduce the opportunity for interference disrupting the signal cables. Power cables can emit energy that can degrade the signal in the signals cables. The higher the voltage on the power cables the further from the signal cables they should be installed.

The GE Network Control Board DS3800HLNC is designed for quick installation in the drive. The board features a modular connector on 1 end and retention levers on the other end. The board is populated with 1 40-pin connector between the retention levers. The GE Network Control Board DS3800HLNC also is populated with a microprocessor and 1 amber indicator LED. The board is also populated with 8 sockets for electrically erasable programmable read-only memory (EEPROM) modules and 21 jumpers.

The indicator LED on the GE Network Control Board DS3800HLNC is situated so that the operator can view the LED while normal processing is taking place. When the amber LED is off, it indicates that the board is processing as designed on that no intervention by the operator is required. If the LED is on, it indicates that a fault has occurred on the board and that power is present in the board. A first troubleshooting step is to suspect that the control signals have gotten out of sequence which makes them unreadable by the board. If that happens it is an easy step to attempt to restore the control signals and regain processing activity.

First you must remove all power from the drive. The drive receives power from several sources. Some of the current is ac current which is shut off from a circuit breaker. Some of the power is dc current which is supplied by a rectifier. The rectifier can be shut off by removing the fuse.

The board is also populated with 8 sockets for electrically erasable programmable read-only memory (EEPROM) modules and 21 jumpers.

The GE Network Control Board DS3800HLNC1A1A can be replaced if it is found to be defective. When you receive the replacement board, you will find that the EEPROM sockets are empty. This is expected because it is normal practice to remove the modules from the defective board and install them in the replacement board. During normal operation the microprocessor on the board uses the firmware and other instruction code stored on the modules to process control signals. The firmware and instruction code is used repeatedly and the firmware and instruction code is never changed. This means the code never changes and the processing never varies.

To ensure that the processing with the new board doesn’t change, use the same firmware and instruction code. Consider that the modules are easily damaged by static electricity. To prevent damage, wear a wrist strap when you handle the modules. The socket provides a slot between the module and the socket into which you can insert a screwdriver. Move the screwdriver blade up and down to remove the module. Repeat the action on the other side of the socket.

The board is also populated with 8 sockets for electrically erasable programmable read-only memory (EEPROM) modules and 21 jumpers.

Because the GE Network Control Board DS3800HLNC1B1B can have a maximum of 8 EEPROM modules, care must be taken that you install them in the right socket on the replacement board. Each socket is assigned an ID that is printed on the surface of the board. When you are ready to move the modules to the new board, move each module individually. That is, remove 1 module from a socket and note the ID assigned to the socket. Then, locate the same socket on the replacement board. Align the module over the socket and press it into the socket. Then repeat the process for all the modules.

Another task is to set the jumpers on the replacement board. The jumpers are set when the first board is installed. Engineers and operators supply input about the best configuration to use for the board. To configure the replacement board you can access the written record of the jumper settings and set the jumpers to match. Use 1 hand to lift the jumper off the pins and move it over the pins you want to cover.

The GE Network Controller Board DS3800HLND also is populated with 1 40-pin connector and 1 20-pin connector. When you install the board, the last task of board installation is connecting ribbon cables to the connectors. This is because the connectors are accessible when the board is installed in the board rack. When you install the board, the modular connectors on the board and on the board rack meet and connect. They provide the connection for the current used to power the board. They also enable command signals to be received by the board. The modular connectors provide the means for transmitting signals to other boards.

The 40-pin and 20-pin connectors also enable transmitting and receiving signals. The connectors are attached to other components through ribbon cables attached to the components. The ribbon cable must be routed properly. Keep the ribbon cables clear of any power cables in the drive. The power cables will emit signals that interfere with signals in the ribbon cables. It is best practice to route any power cables through ports in the drive and away from the ribbon cables.

The microprocessor on the GE Network Controller Board DS3800HLNE is a dedicated device that controls the networking functionality. The microprocessor is installed in a socket and the socket is embedded on the board. The microprocessor generates heat during normal operation and so you must consider how to keep the microprocessor cool, as well as the drive in which it is installed. When the board is installed select a rack location with at least 3 inches of open space around it for air to move freely over the microprocessor. If air cannot remove the excessive heat from the board, the drive might overheat. Make sure the ribbon cables inside the drive do not block air flow.

If the drive shuts down, run the diagnostic tools to access a log of the recent errors. You might find that the drive experienced an overheat condition. This will automatically shutdown the drive. Before you restart the drive, check that the air flow is not blocked. This is critical that the air vents at the top and bottom of the drive are clear.

If you find that 1 GE Log Dr Bus Interface Board DS3800HLOA is defective, it is easy to replace the defective board with a new board. This is due in part because of the modular connector on the rear of the board. The drive has a matching connector on the rear of the board rack. When you slide the board into the rack the two modular connectors meet. They are designed to so that when one slides into the other, electrical and signal connections are made to allow the board to function.

The other usability feature is the retention levers on the other end of the board. When you slide the board into the rack, the modular connectors attach and the retention levers align with the board rack. Press down on the levers to lock the board in the drive. This also locks the modular connectors together and ensures power and signal connectivity.

One important consideration is that the drive must have all power removed before installing the board. The drive has more than 1 source of electrical power.

The GE Log Dr Bus Interface Board DS3800HLOA1D1B comes packaged in a sealed static-protective bag. This is because the board can be damaged by static build up. When you carry the board, static accumulates on your person from the air surrounding you and from the friction of walking. The static builds up on the board if it has no grounded surface to drain to. If you wear a properly installed wrist strap, the static will exit the board and your person. One end of the strap is connected a grounded surface. This might be a metal chair leg, a metal shelf, or a metal desk. This serves as a ground which the static electricity is attracted to. The static drains to the grounded surface and leaves the board unharmed.

If the wrist strap is connected to a wooden or plastic object, the static will not exit your person and instead will accumulate on the board. Make sure the wrist strap is properly connected to a grounded surface on one end and firmly wrapped to your wrist on the other end.

The board also features 8 jumpers and 1 erasable programmable read-only memory (EPROM) module.

The GE Log Dr Bus Interface Board DS3800HLOA1E1C comes in a sealed plastic bag. The bag keeps static electricity from entering the board. Static is harmful to the board so it is best to keep the board in the bag. When you plan to install the board, only then should you slice open the bag with a sharp blade. Use 2 hands to remove the board and hold the board by the edges. Do not handle the components when you remove the board. You might accidently press down on the components and bend them or cause them to break off the board.

Align the board with the board rack and slide the board into the rack until the modular connectors meet. One modular connector is at the bottom of the rack. The other modular connector is embedded on the GE Log Dr Bus Interface Board DS3800HLOA1E1C. They are designed to fit together. Some of the connectors carry the current to power the board. Some of the connectors carry the command signals that are transmitted from the board. Others carry the signals that are received by the board for processing.

The GE Network Controller Board DS3800HMPG is designed for quick installation in the drive. The board features a modular connector on 1 end and retention levers on the other end. The GE Network Controller Board DS3800HMPG also is populated with 2 red indicator LEDs and 1 amber LED which are visible from the front of the board. The board also is populated with a microprocessor, erasable programmable read-only memory (EPROM) modules, and a 34-pin connector.

The GE Network Controller Board DS3800HMPG is populated with 4 standoffs that enable a daughter card to be attached. A daughter card provides additional functionality to the board. The daughter card snaps onto the standoffs and a connector attaches the daughter card to the board.

The microprocessor embedded on the board provides the logic used to control the board operations. The microprocessor generates heat during operation so keeping the drive from overheating requires some consideration. Cool air must be available to the drive for cooling. This is a challenge because often the drive is located in a room with other drives and other powerful equipment. When you inspect the space notice if the wall on which the drive will be installed in hot to the touch. If it is hot, the cause might be that the space on the other side of the wall is hot or equipment installed on the wall is generating heat. To cool the wall, you can reduce the number of drives installed in the room. You can also select a wall that is cooler to the touch for installation of the drive.

The GE Network Controller Board DS3800HMPG1C1C is designed for quick installation in the drive. The board features a modular connector on 1 end and retention levers on the other end. The GE Network Controller Board DS3800HMPG1C1C also is populated with 2 red indicator LEDs and 1 amber LED which are visible from the front of the board. The board also is populated with a microprocessor, erasable programmable read-only memory (EPROM) modules, and a 34-pin connector.

The GE Network Controller Board DS3800HMPG1C1C uses the EPROM modules to store the programming instructions and firmware used by the microprocessor. You will notice that the replacement board comes with empty module sockets. This is because best practice is to remove the modules from the old board and install them on the replacement board. Because microprocessor must behave the same as the original microprocessor, it is always best to use the same programming code and firmware. In this way, the board will behave the same. This enables the drive to resume activities and mimic the drive performance experienced when the original board was installed.

The operator can monitor the operation of the board by viewing the indicator LEDs. When the drive receives power and begins operation, the LED on the board all light for a few seconds. This enables a servicer to confirm that the LEDs are operational. If the startup sequence of diagnostic tests are completed successfully, the amber LED is lit and remains lit while the drive is in operation. It also indicates that the board is receiving power. If the amber LED is not lit, it indicates that the board is not receiving power.

The GE CPU Board DS3800HMPG1D1D is designed for quick installation in the drive. The board features a modular connector on 1 end and retention levers on the other end. The GE CPU Board DS3800HMPG1D1D also is populated with 2 red indicator LEDs and 1 amber LED which are visible from the front of the board. The board also is populated with a microprocessor, erasable programmable read-only memory (EPROM) modules, and a 34-pin connector.

The GE CPU Board DS3800HMPG1D1D also is populated with 2 50-pin connectors on the board. Because the board can have a maximum of 3 ribbon cables, the routing of the cables is important. Improper cable routing can cause the flow of air through the drive to be inadequate. This can lead to the drive overheating. An overheat trip condition can shutdown the drive to protect the drive from damage. To resolve the overheat condition before it becomes a problem, route the cable along the inside wall of the drive and keep the cables from blocking the bottom and top air vents. The bottom air vents draw cool air into the drive. The air travels through the drive and exhausts the hot air through the top air vents. Do not allow the ribbon cables to block the air vents.

Also, if any power cables are routed inside the drive, separate them from the signal cables. The power cables can emit interference that degrades the signals. It is best to route the power cables out of the drive through the ports on the side of the drive.

The board also is populated with a microprocessor, erasable programmable read-only memory (EPROM) modules, and a 34-pin connector.

Before you begin any maintenance or service on the drive, including replacing the GE CPU Board DS3800HMPG1G1D, there are some preliminary considerations to keep in mind. The drive is a high-voltage device that can cause serious injury if the servicer is shocked by the electric current. You must also understand the danger caused by the powerful motor and moving parts. They can also cause injury. Visually inspect the area and note any moisture or water on the floor. Because water is a conductor, it is a hazard to have water on the floor while working with high-voltage current. Use towels or another method to dry the floor completely. If the floor is moist from condensation, consider installing a dehumidifier or other device to dry the air. If any devices are attached to 2-wire extension cords, remove the extension cords from the area around drive. They are a shock hazard and are not safe to have in the area.

Locate and inspect all the emergency shutdown devices associated with the drive. Make sure they are functional and are easy to find in an emergency.

The GE Microprocessor Board DS3800HMPK is designed for quick installation in the drive. The board features a modular connector on 1 end and retention levers on the other end. The GE Microprocessor Board DS3800HMPK also is populated with 3 red indicator LEDs and 1 amber LED which are visible from the front of the board. The board also is populated with a microprocessor, erasable programmable read-only memory (EPROM) modules, and a 34-pin connector. It also is populated with 2 50-pin connectors.

The microprocessor is a heat producing component. The 2 50-pin connectors are adjacent to it and they are attached to ribbon cables. The ribbon cables can block the air flow from cooling off the microprocessor. Excessive heat can damage the microprocessor or degrade the reliability of the microprocessor. It can even cause the drive to shutdown if the heat rises above a threshold. To keep that from happening, install the drive in a location with fresh room temperature air. Avoid installing the drive in a room full of other drives and equipment. The drives and equipment generate heat and without proper management, they can allow heat to build up.

Install fans to dissipate the heat. The powerful fans should be wall mounted to prevent clutter on the floor. Make sure they are in good condition and that you install enough to circulate air throughout the room. If more robust solutions are needed, vent hoods can be installed over the equipment. They draw heat and dust out of the room. Another solution is to remove some of the heat-generating equipment from the room.

Because the GE Microprocessor Board DS3800HMPK1B1B is populated with a microprocessor, special consideration must be given to reducing the heat inside the drive. The microprocessor generates heat which must be exhausted from the drive. The drive must be installed in a location with room-temperature air. This is problematic in some locations due to the number of drives and other heavy-duty machines installed in the room.

However, there are some ways to remedy the situation. The drive is installed on a wall or other vertical surface. If the wall is warm before you install the drive, take steps to cool the wall before installation. Inspect the room on the other side of the wall and notice the number of drives installed in the room. If the room temperature is too warm because of the drives, consider reducing the number of drives installed in the room. Another possibility is to install exhaust fans to remove the excessive heat from the room. The exhaust fans can also remove dust, dirt, moisture, and oil from the room air. This would result is a cool and clean environment.

When you plan to replace the GE Microprocessor Board DS3800HMPK1C1B there are some steps to take before you remove the defective board. Notice that the 2 50-pin connectors is assigned IDs that are printed on the board. The prefix of each is the letter J. Following the prefix is a unique suffix. The ID for 1 50-pin connector is JD and the ID for the other 50-pin connector is JC. To avoid confusion when you install the board and connect the 50-pin connectors, label each 50-pin ribbon cable with the ID of the connector to which it is plugged into. This will avoid problems associated with plugging the ribbon cables in to the wrong connector.

The jumpers are set by an installer to configure the board to send and receive signals and process information as needed for the drive function. The jumper positions are recorded and saved with other important information concerning the drive. Before you install the replacement drive, set the jumpers to match the original board as recorded by the installer of the original board.

When the amber indicator LED is lit, it means that the board is experiencing a warning condition. It also means that power is still applied to the board. It is best practice to resolve the issue when possible to restore function to the drive and the board. The first step to resolving the situation is to restart the board. It might be that interference has caused the command signals to be out of sequence or jumbled. A restart button is located on the board near the 34-pin connector. It is for use by a qualified servicer only due to the possibility of a high-voltage electric shock if components are touched while power is present in the board.

The restart button temporarily stops processing on the board without shutting off power. After a number of seconds, processing is automatically restarted without user intervention. Carefully press the button without touching other components. If the problem is resolved, the amber LED will cease to be lit and normal processing will resume.
