The GE Gas Turbine Daughter Board DS3800HCMC1C1C features a modular connector for attachment to a drive and retention levers to hold the board in the drive. The GE Gas Turbine Daughter Board DS3800HCMC1C1C also is populated with 14 jumpers, and 1 amber and 2 red indicator LEDs. The board also has 2 34-pin connectors, and multiple capacitors and resistors.
The resistors and capacitors are embedded on the board and are designed to assist in the processing functionality of the board. The capacitors present a safety concern that the technician or installer must address. The capacitors are included on the individual circuits on the board and they store electric current during processing. When needed, the capacitors release the current. This happens without intervention by the operator. It also presents no danger to the operator or other individuals in the area of the drive. When the board is removed from the drive, special consideration must be given to the fact that power is stored in the capacitors. The current might pose a shock hazard to individuals if the servicer touches the board. However, the current will exit the capacitors, if you wait 30 seconds after power is removed from the drive.
The capacitors and resistors cannot be individually configured. However, the functionality of the board can be configured through use of the jumpers. The jumpers have unique IDs printed on the surface of the board. The suffix of the IDs is the letter J. The suffix is followed by a unique numerical value. Some of the IDs of the jumpers are J1, J10, and J14.
