Product Description
This DS200GSIAG1BBB printed circuit board, as mentioned above, was originally manufactured for the Mark V Turbine Control System, a General Electric-manufactured legacy series. The Mark V Series that this GSIA-abbreviated printed circuit board or PCB for short exists within is classified as a legacy series as it is no longer being manufactured by its original General Electric retailer. With that being said, the Mark V Turbine Control System Series is a relatively recently-developed product that makes use of General Electric's patented Speedtronic technology, as the Speedtronic style of control system was introduced first with the Mark I Series released in the late 1960s. This DS200GSIAG1BBB printed circuit board is more accurately by its official functional product description as a Common Bus Regenerative Card or Common Bus Regenerative Board; the description that it is solely referred to by in original General Electric and Mark V Series instructional manual materials. This DS200GSIAG1BBB printed circuit board is not the original Common Bus Regenerative Board manufactured for placement in the Mark V Turbine Control System Series; that would be the DS200GSIAG1 parent printed circuit board missing this GSIA-abbreviated products three B-rated product revisions.
Hardware Tips and Specifications
As with any General Electric Mark V Series product offering, this DS200GSIAG1BBB Common Bus Regenerative Board necessitates its own particular series of hardware component inclusions and specifications. The GE Common DC Bus Regenerative Board DS200GSIAG1BBB contains three 40-pin connectors, two 16-pin connectors, and 6 jumpers. The board also has 1 8-pin connector, and multiple test points. The DS200GSIAG1BBB alphanumeric product number itself is a strong source of original hardware identification information for this DS200GSIAG1BBB product, containing details such as this DS200GSIAG1BBB PCB's:
- Normal Mark V Series assembly version
- Domestic location of original manufacture
- GSIA functional product abbreviations
- Normal style of PCB protective coating
- Group One Mark V Series grouping
- Full three-fold revision history
All the jumpers on the board are identified with a series of letters and numbers printed on the board. All jumper identifiers begin with the letters JP. For example, JP1, JP2, and JP3. The one LED on the board is identified through the help of the diagnostic label CR, whereas the DS200GSIAG1BBB board's various test point identifiers begin with the letters TP. The test points are useful when the board is not behaving as expected and a servicer is attempting to pinpoint the defective circuit. The board must be removed from the drive to use the test points. One method is to install a replacement board in the drive and if the problem is resolved, you know the board is defective. Next, use the test points to test the circuits and components on the board and if possible, have the board repaired. In that way, you have a readily available replacement board, if a replacement board is required. Original General Electric instructional materials detail the testing process of this static-sensitive Mark V Series printed circuit board. To begin the diagnostic testing process, place the board on a flat surface with a static protective surface under the board. The test points are bare metal spears that you connect to a tester, or touch with a probe. Before attempting a test, make sure the probe is compatible with the testing device and is functional, and that the tester is calibrated correctly and that the controls on the device are set for the test being performed.
