Product Description

The GE Emergency Overspeed Board DS200TCEAG2B features one microprocessor and sockets for multiple erasable programmable read only memory (EPROM) modules. It also contains 3 fuses, 30 jumpers, and a pair of bayonet connectors. The GE Emergency Overspeed Board DS200TCEAG2B also is populated with multiple test points. The test points enable a servicer with the proper equipment to test the circuits on the board. Each test point has an ID. Some of the IDs assigned to the test points are ANALOG OUTPUT, COM, P5, JW, and RESET. Circuit testing is a valuable troubleshooting tool if you suspect that the board is not functioning properly.

Another troubleshooting tool is the series of LED lights mounted in the side of the board. It is visible when the board is installed in the drive board rack cabinet. If the green LED is lit, it indicates that the board is receiving power and is functioning. When the board is flashing, it indicates the board is processing normally. If the LED is not lit up, it indicates that the board is not receiving power or is not operating.

The board is populated with several capacitors that store current during normal operation of the board. Then, the capacitors release the voltage to power some functions of the board. When you power down the drive, the capacitors might have high voltage stored on them. Before you touch the board, wait 30 seconds after you remove power from the drive to allow time for the power to exit the capacitors.
