MIN. FREQUENCY GENSET

UnclassifiedFuel

What This Code Means

Engine stops; Acoustic alarm activates; Digital alarm output (AL) activates; LED of RESET button flashes; LED of RESET button remains lit (ON); Warning triggered (engine does not stop); Fuel level alarm active; Genset minimum frequency anomaly; RESET button LED flashes; RESET button LED remains ON; Front panel LEDs light up indicating digital/analog sensor alarms; Front panel LEDs light up indicating analog sensor warnings; Display shows MIN. FREQUENCY GENSET in the failure record; Active alarms or warnings displayed on the visualization module screen

Possible Causes

  • •Anomalies detected by digital sensors (digital inputs)
  • •Failure condition continuing for a programmable period of time (Times table parameter 14)
  • •Anomalies detected by analog sensors (analog inputs)
  • •Low fuel level anomaly
  • •Engine generator frequency drops below minimum limit
  • •Anomalies causing the engine to stop (alarms)
  • •Failure condition detected by digital sensors (digital inputs)
  • •Failure condition detected by analog sensors (analog inputs) continuing for programmable period (Parameter 14)
  • •Errors which do not stop the engine (warnings)
  • •Analog sensor alarm threshold reached
  • •Generator set frequency drops below the minimum limit
  • •Low fuel level
  • •Anomaly detected by digital sensor (digital input)
  • •Anomaly detected by analog sensor (analog input)
  • •Failure condition continues for a programmable period of time (Times table parameter 14)

Suggested Actions

  1. 1Press RESET button once to visualize active alarms and warnings
  2. 2Use the UP and DOWN buttons of the display to navigate the failure record
  3. 3Acknowledge and reset the alarm to restart the engine (only if the alarm is no longer active)
  4. 4Press RESET button once to visualize active warnings
  5. 5Reset the warning to erase it from the display (only if the warning is no longer active)
  6. 6Alarm automatically resets (no manual reset required)
  7. 7Press RESET button once to visualize active errors
  8. 8Use UP and DOWN display buttons to navigate the failure record
  9. 9Manually acknowledge and reset the alarm to restart the engine (only possible if the alarm is no longer active)
  10. 10Manually reset the warning to erase it from the display (only possible if the warning is no longer active)
  11. 11Acknowledge and reset the failure message
  12. 12The fuel level alarm is automatically reset once the condition is cleared
  13. 13Press the RESET button once to visualize the record of active alarms and warnings
  14. 14Use the UP and DOWN display buttons to navigate forward and backward in the failure record
  15. 15Acknowledge and reset non-active engine-stop alarms to enable restarting of the engine
  16. 16Reset warnings produced by analog inputs to erase them from the display (provided they are no longer active)
