| Symptom | Cause | Remedy |
|---|---|---|
| Battle short mode | If enabled and the battle short switch is active, some shutdown faults will be bypassed. However, emergency stop shutdowns and other critical faults are not bypassed. | |
| Derate | The derate function reduces output power of the genset in response to a fault condition. Commands will be issued to reduce load via contact closures or ModBus if on an isolated bus, and by lowering base load kW to target kW if in utility parallel mode. | |
| Emergency stop | Annunciated whenever either emergency stop signal is received from an external switch. | |
| Low and high battery voltage warning | Indicates status of the battery charging system (failure) by continuously monitoring battery voltage. | |
| Weak battery warning | The control system will test the battery each time the genset is signaled to start and indicate a warning if the battery indicates impending failure. | |
| Fail to start (overcrank) shutdown | The control system will indicate a fault if the genset fails to start by the completion of the engine crack sequence. | |
| Fail to crank shutdown | Control has signaled starter to crank engine but engine does not rotate. | |
| Cranking lockout | The control will not allow the starter to attempt to engage or to crank the engine when the engine is rotating. | |
| Fault simulation | The control in conjunction with InPower software, allows a technician to verify the proper operation of the control and its interface by simulating failure modes or forcing the control to operate outside of its normal operating ranges. | |
| Off load running (protection) | Protects the engine in the event the genset is being called to go off load for too long. | |
| Overspeed shutdown | Default setting is 115% of nominal. | |
| Low lube oil pressure warning/shutdown | Level is preset (configurable with InPower or HMI) to match the capabilities of the engine used. Control includes time delays to prevent nuisance alarms. | |
| High lube oil temperature warning/shutdown | Level is preset (configurable with InPower or HMI) to match the capabilities of the engine used. Control includes time delays to prevent nuisance alarms. | |
| High engine temperature warning/shutdown | Level is preset (configurable with InPower or HMI) to match the capabilities of the engine used. Control includes time delays to prevent nuisance alarms. | |
| Low coolant temperature warning | Indicates that engine temperature may not be high enough for a 10 second start or proper load acceptance. Can be set up to be a warning or shutdown. | |
| High intake manifold temperature shutdown | Level is preset (configurable with InPower or HMI) to match the capabilities of the engine used. Control includes time delays to prevent nuisance alarms. | |
