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


CID 500 FMI 12 EMCP Electronic Control (Generator Set) Failed - Test

Usage:

3304 02B
A CID 500 FMI 12 means that the GSC is unable to accurately measure the AC voltage and the AC current. The engine remains able to run. The engine also remains able to start.

Note: On the GSC, the CID 500 FMI 12 will be shown even when the engine control switch (ECS) is in the OFF/RESET position.

Procedure

If a CID 500 FMI 12 occurs, replace the GSC. See Testing And Adjusting, "EMCP Electronic Control (Generator Set) - Replace".


NOTICE

If a CID 500 FMI 12 occurs and the engine is running, the generator output may be at full voltage potential. This could occur even if the GSC display is showing 0 AC volts and 0 AC current for all three phases.
