2814

UnclassifiedGeneral

What This Code Means

Generator set dumps its electrical load; Generator set KW output exceeds the Overload Threshold for the Overload Set Time; Output frequency of the generator set drops below the Under-frequency Offset for the Under-frequency Set Time

Possible Causes

  • •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 CT Ratio Setup Or Feature Code
  • •Incorrect CTs or CT Connections
  • •Incorrect CTs or CT connections
  • •Incorrect Voltage Or kW Rating Setup
  • •Overload Set Time or Under-frequency Set Time is set too low
  • •The CTs Are Incorrectly Sized
  • •Under-frequency Offset is set too low

Suggested Actions

  1. 1Change the CTs to the correct size.
  2. 2Check the CTs, CT Connections, and CT ratio
  3. 3Check the CTs, CT connections, and CT ratio
  4. 4Enter the correct CT ratio via InPower or through the operator panel by navigating to Setup > OEM Setup > OEM Alt Setup > Genset CT Ratio and set the 'Genset CT Ratio primary' and 'Genset CT Ratio secondary' parameters 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 the CT ratio calculator in InPower to determine the correct CT ratio for this generator set.
