Information:

System Operation Description:The engine does not shut down when a shutdown fault occurs.There are several possible causes why an engine is not shutting down when a shutdown fault occurs:
Illustration 1 g00519201
System Schematic For Unexpected ShutdownNote: It is extremely important that GSC setpoint P23 is correct for the engine application. Make certain setpoint P23 is programmed correctly for the engine application before continuing with this procedure. Note: It is extremely important that GSC setpoint P01 is correct for the engine. All generator sets packaged in Larne, Ireland with serial numbers (your list of S/N's) must ALWAYS have this setpoint programmed to 0 (ETR fuel solenoid) for both fuel solenoid types (ETR or ETS). There are several possible causes why an engine is not shutting down when a shutdown fault occurs.
Operator Error: The operating conditions of the generator may not be understood by the operator. Ensure that the condition is one that should cause an engine shutdown.
Programming Error - Fault Is Overridden Or Disabled: It is possible to program the GSC in order to override certain shutdown faults. An overridden shutdown fault will be treated as an alarm fault. The YELLOW fault alarm indicator will be FLASHING instead of the RED fault shutdown indicator. If the GSC is programmed in order to disable a particular fault, there will not be any fault indicators or codes shown on the GSC. In these cases, it is a good idea to check any setpoints related to that fault. For example, if a genset is not shutting down when an overvoltage fault occurs, make sure setpoint P104(Overvoltage shutdown enable) is programmed correctly.
Programming Error - Setpoints Incorrect For Application Or Customer Needs: It is possible to program the GSC setpoints to a value that does not allow the situation to be recognized by the GSC as a shutdown condition. In this case, check the appropriate setpoints for correct values. For example, if the genset is not shutting down when a high coolant temperature condition occurs, make sure setpoint P15 (High Water Temperature Shutdown) is correct for the application.
Faulty Component: Some examples of faulty components that could prevent the GSC from shutting down the engine are: PEEC, GSC and a broken or shorted harness wire.. In this case, the GSC or PEEC will be issuing a command to shut down the engine due to a diagnostic code, but the engine remains running. Test Step 1. CHECK FOR DIAGNOSTIC CODES
Check the GSC for a diagnostic code on the upper display.Expected Result:The GSC should show a diagnostic code on the upper display.Results:
YES - The GSC shows a diagnostic code on the upper display.Repair: See theTesting and Adjusting section of this book for the diagnostic code that is displayed on the GSC. Stop.
NO - The GSC does NOT show a diagnostic code on the upper display. Proceed to Test Step 2.Test Step 2. CHECK THE YELLOW FAULT ALARM INDICATOR
Check the display area of the GSC for the yellow fault alarm indicator.Expected Result:The fault alarm indicator should be
