Product Description
The GE RST Extended Analog I/O Board DS200TCQBG2A is populated with a programmable logic device and EPROM modules. The GE RST Extended Analog I/O Board DS200TCQBG1BCB also has 1 OK LED that is viewable from the side, 1 50-pin connector, and 15 jumpers. The GE RST Extended Analog I/O Board DS200TCQBG2A also is populated with multiple test points that are valuable for testing the specific circuits on the board. The test points have IDs that are prefixed with TP and suffixed with a number. For example, the ID for one test point is TP1 and for another the ID is TP12. To use a test point the servicer must have a testing device that is designed for performing the specific test on the circuit board. The testing device must be fully calibrated. Also, the settings on the front of the testing device must be appropriate for the testing. Place the board on a static protective surface, such as a flattened EDS protective bag. And always wear a wrist strap when you work with a board or perform any work in the drive.
The first indication you might have that the board is not functioning is that the green LED on the side of the board is not lit. When the board is receiving power and the board is performing as designed, the LED is lit and is visible from the board cabinet while the drive in operational. When the LED is not lit while the board is receiving power, circuits on the board might be defective and testing the circuits might pinpoint the problem.
