INPHASE MONITOR (IPM) SYNCHING

UnclassifiedGeneral

What This Code Means

The two sources did not synchronize within the Fail to Sync time delay

Possible Causes

  • •Generator set frequency misadjustment
  • •Generator set frequency out of sync
  • •Incorrect inphase monitor angle
  • •Incorrect synchronization settings for voltage differential, frequency differential, or phase angle
  • •Inphase monitor angle misadjusted

Suggested Actions

  1. 1Adjust inphase monitor angle
  2. 2Adjust the generator set frequency in order to achieve source synchronization
  3. 3Adjust the generator set frequency in order to achieve source synchronization (refer to Generator set manuals)
  4. 4Check synchronization settings for voltage differential, frequency differential, and phase angle (See TP-6714, MPAC 1500 Controller Operation Manual)
  5. 5Connect IPM Synching output to customer-supplied equipment to boost the generator set if the sources do not synchronize
  6. 6Set the programmed-transition override function to allow a programmed-transition transfer in the event that the sources do not synchronize
