The undesignated fault functions may also be programmed for non-shutdown or non-time delay. | |
| Fault lamp lights but no fault exists. Engine gauges show oil pressure, engine temperature, and frequency (speed) are within normal limits. | The monitor board or a sensor may be at fault. Contact an authorized service center for service. | |
| Engine starts from generator control panel but will not start automatically or from a remote panel. | Remote circuit breaker is tripped. Reset breaker and restart. Contact an authorized service center if breaker trips after resetting. | |
| Engine will not crank. | A. Fault lamp on. Correct fault and reset control. b. Poor battery cable connections. Clean the battery cable terminals and tighten all connections. c. Discharged or defective battery. Recharge or replace the battery. d. Emergency stop button (if equipped) pushed in. To reset, pull switch out and move Run/Stop/Remote switch to Stop position. Then push test switch to Reset/Lamp position. e. Contact an authorized service center if none of the above. | |
