Electronic Modular Control Panel II (EMCP II) For PEEC Engines Caterpillar

This is an internal fault of the GSC that can be temporary or permanent. The fault is caused by a component failure in the GSC. The fault could also be caused by extremely severe electromagnetic interference or radio frequency interference. The relays in the relay module are automatically turned off when this fault occurs. This fault will shut down the engine.

1. Reset the GSC.

   1. Turn the ECS to OFF/RESET. If the GSC does not power down, remove the jumper that connects terminals 6 and 9 on the ECS.

   2. Turn the ECS to STOP.

      Expected Result: The GSC should power up with an identifiable display. The GSC should respond to the ECS.

      Results:

      • OK - The GSC operates correctly. Therefore, the fault is gone. STOP.

      • NOT OK - The GSC does NOT operate correctly and the fault shutdown indicator still flashes at a rate of four to five times a second (4 to 5 Hz). Therefore, the GSC is faulty. Replace the GSC. See Testing And Adjusting, "EMCP Electronic Control (Generator Set) - Replace". STOP.
