Appendix D—Modbus Register Map358 Power Xpert C445 Global Motor Management Relay MN042003EN—January 2019 www.eaton.com1030 Undervoltage Start Delay UINT16 RW NVDefault: 20Range: 0 to 60Units: secondsConfig CRCAdmin LockUSB LockBackup MemUndervoltage Start Delay is a delay to prevent this protection, if enabled,from tripping the motor at start up until this time expires. If theUndervoltage condition is still present after this time delay, then a tripwould occur following the Undervoltage Trip Delay Time.1031 Undervoltage Trip Delay UINT16 RW NVDefault: 20Range: 1 to 60Units: secondsConfig CRCAdmin LockUSB LockBackup MemUndervoltage Trip Delay is the time delay following the trip level beingexceeded until a trip occurs.1032 Voltage Loss Restart LossLevelUINT8 RW NVDefault: 70Range: 65 to 90Units: %Config CRCRun LockAdmin LockUSB LockBackup MemVoltage Loss Restart Loss Level is the level of voltage that C445 willconsider a voltage loss to start the time intervals for Voltage Loss RestartAction.1033 Voltage Loss Restart ReturnLevelUINT8 RW NVDefault: 90Range: 80 to 100Units: %Config CRCRun LockAdmin LockUSB LockBackup MemVoltage Loss Restart Return Level is the voltage level that line voltagemust return to for C445 to re-start motors. If the level returns to this pointor above within the time intervals specified by the user (VLR Short Timeand VLR Long Time), a restart sequence will be initiated according to usersettable delays (VLR Short Delay and VLR Long Delay).1034 Voltage Loss Restart AutoTimeUINT16 RW NVDefault: 200Range: 100 to 400Units: msConfig CRCRun LockAdmin LockUSB LockBackup MemVoltage Loss Restart Time Interval for The Auto Time Period. C445 willhold its output relay shut for this time period after voltage loss toautomatically pull the contactor back in as soon as voltage returns. Ifcontrol power is lost, C445 can remain powered for approximately 200msat 70% control power.1035 Voltage Loss Restart ShortDelayUINT32 RW NVDefault: 1000Range: 100 to 500000Units: msConfig CRCAdmin LockUSB LockBackup MemVoltage Loss Restart Short Delay. If voltage returns to the user specifiedlevel within the short time period C445 will send a command to re-startthe motor after the Short Time Delay.Table 128.
