Protections 7.7 DC OVERCURRENT WARNING/ ELECTRICAL TRIP/SHUTDOWN ALARM The overcurrent alarm combines a simple warning trip level with a fully functioning IDMT curve for thermal protection. 7.7.1 IMMEDIATE WARNING If the Immediate Warning is enabled, the controller generates a warning alarm as soon as the Trip level is reached.
Page 96
Protections Factory settings for the IDMT Alarm are as follows (screen capture from the DSE Configuration Suite PC software): (Trip setting value) (time multiplier) These settings provide for normal running of the generator up to full load. If full load is surpassed, the Immediate Warning alarm is triggered, the set continues to run.
Protections 7.8 DC SHORT CIRCUIT ALARM If the Short Circuit alarm is enabled, the controller begins following the IDMT ‘curve’. If the Trip is surpassed for an excess amount of time the Alarm triggers (Shutdown or Electrical trip as selected in Action).
