Possible Causes

• •Another active fault code set to Derate
• •Another active fault is set to Derate
• •Generator set KW output exceeds Overload Threshold for Overload Set Time
• •Generator set output frequency drops below Under-frequency Offset for Under-frequency Set Time
• •Incorrect CTs or CT Connections
• •Incorrect CTs or CT connections
• •Incorrect CTs, CT connections, or CT ratio
• •Load Dump parameter is enabled and generator set KW output exceeds Overload Threshold for the Overload Set Time
• •Load Dump parameter is enabled and output frequency drops below Under-frequency Offset for the Under-frequency Set Time
• •Overload Set Time or Under-frequency Set Time is set too low
• •PCC is not running in Load Govern paralleling state when a derate request occurs
• •Under-frequency Offset is set too low

Suggested Actions

1. 1Check the CTs, CT Connections, and CT ratio
2. 2Check the CTs, CT connections, and CT ratio
3. 3Go to Setup > Genset Setup on operator panel and set Overload Set Time and Under-frequency Set Time parameters appropriately for the application
4. 4Go to Setup > Genset Setup on operator panel and set Under-frequency Offset parameter appropriately for the application
5. 5Go to Setup > Genset Setup on the operator panel and set the Overload Set Time and Under-frequency Set Time parameters appropriately for the application
6. 6Go to Setup > Genset Setup on the operator panel and set the Under-frequency Offset parameter appropriately for the application
7. 7Refer to the section on Current Transformer Installation or reference event/fault code 2814 and event/fault code 2815
8. 8Troubleshoot other active fault(s) set to Derate
9. 9Troubleshoot the other active fault(s) that are set to Derate
10. 10Use external devices to reduce the load
