Questions and answers
the generator with intellite 9 controller starts but it shuts down by itself after 30 seconds of running displaying an ecu alarm code
Generator not energising mains contactor after mains resume
The ComAp InteliLite 9 generator may not be energizing the mains contactor after mains resume due to several possible reasons:
1. Breaker Control Issue: The generator circuit breaker (GCB) output controls the breaker position, and if the breaker does not react within 5 seconds, an alarm is issued. If the breaker feedback is not properly configured, it may prevent the controller from switching back to the mains.
2. Fuel Level and Pump Control: If the fuel level is below the setpoint for the Fuel Pump On state and has not reached the Fuel Pump Off threshold, the fuel pump may not be operating correctly, affecting the generator's ability to run and transfer back.
3. Alarm Conditions: If there are active alarms, such as Generator Undervoltage, Overfrequency, Underfrequency, or Overload, the system may prevent switching back to the mains contactor for safety reasons.
4. Pause Between Repeated Starts: If the system is in a pause state due to repeated start attempts, it may delay the transition back to the mains.
To resolve the issue, check the breaker feedback configuration, fuel level setpoints, and any active alarms that might be preventing the transition.

Generator shut down. Only fault shows a high level which there is not high fuel. Won’t try to restart. Shows stop on the screen.
A ComAp InteliLite 9 generator could shut down with a high-level fault and not restart due to a shutdown alarm activation. Possible causes include:
1. Low oil pressure – If oil pressure falls below the required threshold.
2. High engine temperature – If the engine overheats beyond safe limits.
3. Generator undervoltage or overvoltage – If the generator voltage is too low or too high.
4. Incorrect phase sequence – If the voltage phase sequence is incorrect.
5. Emergency stop activation – If an emergency stop command is issued.
6. RPM issues – If the engine speed falls below the required level.
7. Fuel solenoid failure – If the fuel solenoid is off and the stop solenoid is on.
8. Generator voltage below 10V – If the generator voltage drops too low.
Once a shutdown condition is detected, the generator will not restart unless the fault is cleared and reset.

How to remove Oil presure senser alarm
To remove the oil pressure sensor alarm on the ComAp InteliLite 9, follow these steps:
1. Check the Sensor – Ensure the oil pressure sensor is functioning correctly and that the measurement value is within range.
2. Acknowledge the Alarm – Press the FAULT RESET button to acknowledge alarms and deactivate the horn output.
3. Confirm Active Alarms – If the alarm is still active, it will change to "confirmed" status and will disappear once the issue is resolved.
4. Inspect Wiring and Connections – Verify that the sensor wiring is intact and properly connected.
5. Restart the Controller – If necessary, restart the controller to reset the alarm system.
6. Monitor the Display – Check the alarm list on the Measurement page to ensure the oil pressure alarm has cleared.
If the alarm persists, inspect for hardware faults or faulty sensor components.
