ALARMS TABLE PARAMETER 70

UnclassifiedElectrical

What This Code Means

Voltage values between genset phases (VG12, VG23, or VG31) are under the minimum programmed limits; Genset frequency is under the minimum programmed frequency limits; No frequency measurement signal detected on the first-phase, second-phase, or third-phase; Unexpected shutdown of the engine; Engine fails to stop (Stop failure)

Possible Causes

  • •Genset phase voltage drops below the thresholds defined in Thresholds table parameter 3
  • •Genset frequency values remain below the thresholds defined in Thresholds table parameter 6 during the stabilization time programmed in Alarms table parameter 65
  • •The controller does not detect all engine starting conditions (regulations table parameters 19 to 22) while the engine is running
  • •All engine stop conditions (regulations table parameters 19 to 22) are not detected 15 seconds after an engine stop attempt

Suggested Actions

  1. 1Stop engine with cooling (automatically triggered action configured by alarms table parameter 63)
  2. 2Stop engine with cooling (automatically triggered action configured by alarms table parameter 66)
  3. 3Disconnect the stop failure alarm (alarms table parameter 70) to allow the device to consider the engine stopped after waiting a maximum of 15 seconds
  4. 4Ensure all engine stopping conditions are detected during the programmed time (alarms table parameter 71)
