Upper Display With AL Fault Code "AL3"
An alarm fault informs the operator of a condition that could cause a dedicated fault shutdown. An alarm fault precedes certain dedicated shutdown faults. Alarm faults are activated automatically by the GSC and the faults depend on certain setpoints. The GSC does not record alarm faults in the fault log.When an alarm fault occurs, the GSC FLASHES the fault alarm indicator. The corresponding alarm code is shown on the upper display after the alarm codes key is pressed. When the alarm fault is no longer active, the alarm fault code is no longer shown on the upper display.

Troubleshooting AL Fault Codes
AL Fault Code Description Troubleshooting
AL1 High Water Temperature Alarm
Coolant temperature increases to within 6°C (11°F)of setpoint P15 See Testing And Adjusting, "Troubleshooting Dedicated Shutdown Indicators".
AL2 Alarm for Low Engine Coolant Temperature
Coolant temperature decreases to setpoint P16. See Testing And Adjusting, "Troubleshooting Dedicated Shutdown Indicators".
AL3 Alarm for Low Engine Oil Pressure
Oil pressure drops to within 34 kPa (5 psi) of the P13 or P14 setpoint See Testing And Adjusting, "Troubleshooting Dedicated Shutdown Indicators". Troubleshooting Procedure
If the operation of the AL fault codes is suspected to be incorrect, perform this procedure.
Check For A Diagnostic Fault.
Check for an active CID 110 diagnostic code or a CID 269 diagnostic code. See Testing And Adjusting, "Troubleshooting Diagnostic Codes". Expected Result: CID 110 or CID 269 should not be showing.Results:
OK - Proceed to next step.
NOT OK - Correct the active CID 110 or CID 269 prior to proceeding with this procedure. See Testing And Adjusting, "Troubleshooting Diagnostic Codes". STOP.
Identify The AL Fault Code That Is Suspected To Be Incorrect.
If AL fault code AL1 or AL3 is suspected to be incorrect, then see Testing And Adjusting, "Troubleshooting Dedicated Shutdown Indicators".
If AL fault code AL2 is suspected to be incorrect, go to 3.
Check The Function Of The Low Engine Coolant Temperature.
Note the setpoint P16 (low water temperature alarm), see Systems Operation, "Setpoint Viewing OP2".
Check and note the actual coolant temperature that is showing on the lower display.
Compare the two temperatures. Expected Results: The actual coolant temperature that is showing on the lower display should be greater than setpoint P16. This actual temperature should not cause an AL2 fault code.Results:
OK - The actual temperature is greater than the setpoint P16 and the alarm fault indicator does not FLASH and AL2 fault code is not showing on the upper display when the alarm code key is pressed. The problem is not present now. The problem may be intermittent. Check the harness and the electrical connections of the circuit for the coolant temperature. See Testing And Adjusting, "Electrical Connector - Test". STOP.
OK - The temperature that is showing on the lower display is greater than setpoint P16. Therefore, the temperatures are not correct for an AL2 fault code. If the AL2 fault remains active, replace the GSC. See Testing And Adjusting, "EMCP Electronic Control (Generator Set) - Replace" for more information. STOP.
NOT OK - The temperature that is showing on the lower display is less than setpoint P16. Therefore, the temperatures are correct for an AL2 fault code. The GSC is operating properly. Make sure that the setpoint P16 is reasonable for the local climate. Adjust, if necessary. Refer to the Engine Service Manual in order to find the cause of the low engine coolant temperature. STOP.Note: If desired, check the accuracy of the temperature that is shown on the lower display of the GSC. Install an accurate engine coolant temperature gauge with the sensing element in an area of high coolant flow. Also, install the gauge as close as possible to the coolant temperature sensor for the EMCP II.
