About the DS200TCEAG2B
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 adopted by this DS200TCEAG2B Emergency Overspeed Board is the series of LED lights mounted in the side of the board. One singluar green-colored LED is visible when the board is installed in the drive board rack cabinet. If this green LED is lit, it indicates that the board is receiving power and is functioning. When the board's green LED 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. In addition to various LEDs, the DS200TCEAG2B 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 and to diffuse any potentially-damaging surface voltages.
In terms of specialized hardware, this DS200TCEAG2B Emergency Overspeed Board offers several product-specialized circuits in its assembly, including but not limited to flame detection, turbine overspeed, and automatic synchronizing circuits. These circuits must be treated with respect during normative use of the DS200TCEAG2B Emergency Overspeed Board, as they are central to its intended function within the Mark V Series. In addition to the specialized circuits gingerly handled in the internal assembly of this DS200TCEAG2B Emergency Overspeed Board, it also utilizes several different styles of General Electric connector.
