System Schematic For The Fuel Control Relay On "EUI" EnginesThe GSC uses the fuel control relay (FCR) in order to activate the fuel control solenoid (FCS). The GSC also uses the fuel control relay (FCR) in order to provide power to the optional electronic governor (EG). The FCR is located within the relay module. The fuel control solenoid is located in the fuel system of the engine. The electronic governor (EG) is located on the subpanel.Some generators use the ETR type of fuel system. In the ETR type of fuel system, the GSC activates the FCR. The FCR energizes the fuel control solenoid in order to RUN the engine.Note: There is another type of fuel system which is called energized to shutdown (ETS). In the ETS, the GSC activates the FCR. The FCR energizes the fuel control solenoid in order to SHUT DOWN the engine.Note: Whenever the GSC activates the FCR or attempts to activate the FCR, "K7" is shown on the lower display. When the FCR is not activated, "K7" is not shown. Also, setpoint P01 selects the type of the fuel control solenoid. 0 = ETR. 1 = ETS.The possible cause of a CID0447 FMI 12 is an open coil or a shorted coil of the FCR.The system responses to these diagnostic codes are listed below.
If a CID 0447 FMI 12 occurs and the engine is running, a CID 0566 FMI 07 will become active. A CID 0566 FMI 07 describes an unexpected shutdown. The shutdown mode is functioning. The engine stops.
If a CID 0447 FMI 12 occurs and the engine is NOT running, then the engine can not start or the engine can not run.The GSC treats a CID 0447 FMI 12 as an alarm fault. Active alarm faults are shown on the display when the "Alarm Codes" key is pressed. Also, the ECS must be in any position except the OFF/RESET position. Clear the diagnostic code from the fault log after troubleshooting is complete.This troubleshooting procedure is for an active CID 0447 FMI 12 or the troubleshooting procedure is for an inactive CID 0447 FMI 12.Test Step 1. CHECK THE STATUS OF THE DIAGNOSTIC CODE.
Turn the ECS to the OFF/RESET position and then turn the ECS to the STOP position.
Press the "Alarm Codes" key.
Observe the upper display. Check that the CID 0447 FMI 12 is active.
If the diagnostic code is not active, enter the Service Mode. View the fault log for a OP1. Check that the diagnostic code is inactive.Expected Result:A CID 0447 FMI 12 is displayed as an active diagnostic code or CID 0447 FMI 12 is displayed as an inactive diagnostic code.Results:
OK - The CID 0447 FMI 12 is active or the CID 0447 FMI 12 is inactive. Proceed to test step 2.
NOT OK - The CID 0447 FMI 12 has not occurred. The diagnostic code is not active and the diagnostic code is not inactive. Stop.Test Step 2. CHECK THE INTERNAL CABLE OF THE RELAY MODULE.Note:
