| Code | Meaning | Cause |
|---|---|---|
| 057-243 | Generator Under Volts gives a warning alarm in the event of the generator output falling below the configured Under Volts Pre-Alarm Trip value for longer than the Activation Delay. | |
| 057-243 | Generator Over Volts gives a warning alarm in the event of the generator output voltage rising above the configured Over Volts Pre-Alarm Trip value for longer than the Activation Delay. | |
| 057-243 | Generator Under Frequency gives a warning alarm in the event of the generator output frequency falling below the configured Under Frequency Pre-Alarm Trip value for longer than the Activation Delay. | |
| 057-243 | Under Speed Alarm | |
| 057-243 | Over Speed Pre-Alarm | |
| 057-243 | Over Speed Alarm | |
| 057-243 | Run Away Shutdown alarm is immediately triggered. | |
| IDMT ALARM | If the Over Current IDMT Alarm is enabled, the controller begins following the IDMT ‘curve’ when the current on any phase passes the Trip setting. If the Trip is surpassed for an excess amount of time, the IDMT Alarm triggers (Shutdown or Electrical Trip as selected in Action). The larger the over circuit fault, the faster the trip. | Generator current exceeds the trip level and remains above it for a duration that surpasses the set threshold. |
| IDMT ALARM | If the Over Current IDMT Alarm is enabled, the controller begins following the IDMT 'curve' when the current on any phase passes the Trip setting. If the Trip is surpassed for an excess amount of time, the IDMT Alarm triggers (Shutdown or Electrical Trip as selected in Action). The larger the over circuit fault, the faster the trip. | Generator current exceeds the IDMT trip setting and remains above it for a duration that triggers the alarm. |
| IMMEDIATE WARNING | If the Immediate Warning is enabled, the controller generates a warning alarm as soon as the Trip level is reached. The alarm automatically resets once the generator loading current falls below the Trip level (unless All Warnings are latched is enabled). | Generator current exceeds the trip level. |

| Mains Over Current | Mains output current rose above the Mains Over Current Trip level. | |
| Mains Phase Seq Wrong | Phase rotation of mains was different to configured Mains Phase Rotation Alarm setting. | |
| Over Speed Alarm | Shutdown alarm in the event of the engine speed rising above the configured Over Speed Alarm Trip value for longer than the Activation Delay. | |
| Over Speed Pre-Alarm | Warning alarm in the event of the engine speed rising above the configured Over Speed Pre-Alarm Trip value for longer than the Activation Delay. The Warning is automatically reset when the engine speed falls below the configured Return level. | |
| Run Away | In the event of the generator output frequency rising above the configured Trip value, the Run Away Shutdown alarm is immediately triggered. This is used to protect against engine damage due to uncontrolled speed increase. | Generator output frequency exceeds the configured trip value. |
| Run Away | Immediate Shutdown alarm triggered when the engine speed rises above the configured Trip value. | |
| Short Circuit IDMT Alarm | Generator output current rose above the Short Circuit Trip for the duration of the IDMT function. | |
