Troubleshooting
7Fault codes
| Code | Meaning | Cause |
|---|
| FAIL TO START | FAIL TO START | if the engine does not fire after the pre-set 3 attempts at starting, a shutdown will be initiated |
| HIGH ENGINE TEMPERATURE | HIGH ENGINE TEMPERATURE | |
| LOW OIL PRESSURE | LOW OIL PRESSURE | if the module detects that the engine oil pressure has fallen below the low oil pressure switch after the Safety On timer has expired |
Symptoms & remedies
| Symptom | Cause |
|---|
| BATTERY CHARGE FAILURE | if the module does not detect a voltage from the warning light terminal on the auxiliary charge alternator |
| Engine coolant temperature has exceeded the high engine temperature switch after the Safety On timer has expired | |
| Overspeed, if the engine speed exceeds the pre-set trip (14% above the nominal frequency) a shutdown is initiated. Overspeed is not delayed, it is an immediate shutdown. | |
| Underspeed, if the engine speed falls below 20Hz (fixed) after the Safety On timer has expired, a shutdown is initiated. | |
