The GE Generator Control Turbine Board DS200CVMAG1ADB contains two 16-pin connectors and one 2-pin connector. The board also is populated with 6 test points. If you have reason to think the board is not performing as expected, there are several ways to diagnose the board. One method is to replace the board with another, if you have a another board available. If you replace the board and the new board resolves the issue, then you know the old board was defective. If the same problem occurs with the new board, then you must suspect other boards and components in the drive.
You can also use the diagnostics tools that come with the drive to find any problems. The diagnostic tools are accessible from the control panel and they provide a complete evaluation of the drive components. You can download the diagnostic file to a laptop for storage and inspection. After you attempt to resolve the issue you can run the diagnostics again and compare the results. If the problem is resolved, the diagnostics results will show the successful resolution of the problem.
The best practice to finding the cause of a problem is to use the test points on the board to test the individual circuits and thereby find the specific defect on the board. Use a tester that is calibrated for the specific task and make sure the controls are set correctly also. Use only probes that are designed for use with the tester device.
