What This Code Means
Utility bus voltage is greater than the Utility Overvoltage Drop-Out Threshold and stays there for a time period greater than the Drop-Out Delay; Specific mismatch regarding comparison of some internal data on the microprocessor; Genset Bus Available Event is active; Hardware Failure Warning active; EEPROM Write Failure Warning active; Unsuccessful attempt to save a trim; The Synchronizing System is not in Auto mode
Possible Causes
- •Utility Undervoltage Threshold is not safe for the connected load
- •Utility Overvoltage Threshold is not safe for the connected load
- •Utility Overvoltage Threshold value is too close to the rated voltage
- •Time delay for this fault is set too low
- •AC voltage sensors are not properly calibrated in the SYNC1320 master synchronizer
- •Incorrect VT connections
- •Microprocessor internal data calibration mismatch
- •Control board failure
- •Related faults and events (1328, 1452, 1225, 1224, 1226, 1913) are inactive simultaneously, Genset Stop Command is inactive, and Generator Circuit Breaker is open or closed
- •Calibration Checksum Warning (Fault Code 2416) is active
- •EEPROM Write Failure Warning (Fault Code 353) is active
- •Utility Bus AC Metering Failure (Fault Code 1335) is active
- •Generator Bus AC Metering Failure (Fault Code 1335) is active
- •The hardware version is not compatible with the software version
- •The current value in RAM memory (to-be-written value) does not match its post-written value in EEPROM
- •Attempt to save a trim by using either InPower or the LCD display is not successful
- •The SYNC1320 master synchronizer fails to automatically save data on a periodic basis
- •Misoperation of relevant terminal blocks (TB10-6) on the SYNC1320 master synchronizer and related switches
- •Faulty cabling from the switches to the terminal blocks
- •Control switch operation is not OK
Suggested Actions
- 1Make sure the Utility Undervoltage Threshold is safe for the connected load
- 2Make sure the Utility Overvoltage Threshold is safe for the connected load
- 3Verify that the threshold value is not too close to the rated voltage
- 4Make sure that the time delay for this fault is not set too low
- 5Make sure that all AC voltage sensors are properly calibrated in the SYNC1320 master synchronizer
- 6Use InPower to monitor and make any necessary adjustment
- 7Check VT connections, if used
- 8Cycle power to the SYNC1320 master synchronizer
- 9If the fault persists, use InPower to perform an Initial Calibration
- 10If the problem continues, replace the control board
- 11No action required (this event is for information purposes only)
- 12Identify which of the faults is active by observing the fault displayed on the control panel or observing the lamps on the SYNC1320 control board, or by using InPower
- 13Take corrective steps for the active specific faults
- 14Clear the fault by cycling power to the SYNC1320 master synchronizer
- 15Clear the fault by resetting the processor via an InPower initial calibration
- 16Verify if working in non-Auto mode is intentional
- 17Check relevant terminal blocks (TB10-6) on the SYNC1320 master synchronizer and related switches for misoperation
- 18Check cabling from the switches to the terminal blocks
- 19Make sure the control switch operation is OK
