Undervoltage Start Delay
UINT16 RW NV
Default: 20
Range: 0 to 60
Units: seconds
Config CRC
Admin Lock

Backup Mem
Undervoltage Start Delay is a delay to prevent this protection, if enabled,
from tripping the motor at start up until this time expires. If the
Undervoltage condition is still present after this time delay, then a trip
would occur following the Undervoltage Trip Delay Time.
1031
Undervoltage Trip Delay
UINT16 RW NV
Default: 20
Range: 1 to 60
Units: seconds
Config CRC
Admin Lock
USB Lock
Backup Mem
Undervoltage Trip Delay is the time delay following the trip level being
exceeded until a trip occurs.

Voltage Loss Restart Loss
Level
UINT8 RW NV
Default: 70
Range: 65 to 90
Units: %
Config CRC

Backup Mem
Voltage Loss Restart Loss Level is the level of voltage that C445 will
consider a voltage loss to start the time intervals for Voltage Loss Restart
Action.
1033
Voltage Loss Restart Return
Level
UINT8 RW NV
Default: 90
Range: 80 to 100
Units: %
Config CRC
Run Lock
Admin Lock
USB Lock
Backup Mem
Voltage Loss Restart Return Level is the voltage level that line voltage
must return to for C445 to re-start motors. If the level returns to this point
or above within the time intervals specified by the user (VLR Short Time
and VLR Long Time), a restart sequence will be initiated according to user
settable delays (VLR Short Delay and VLR Long Delay).
1034
Voltage Loss Restart Auto
Time
UINT16 RW NV
Default: 200
Range: 100 to 400
Units: ms
Config CRC
Run Lock
Admin Lock
USB Lock
Backup Mem
Voltage Loss Restart Time Interval for The Auto Time Period. C445 will
hold its output relay shut for this time period after voltage loss to
automatically pull the contactor back in as soon as voltage returns. If
control power is lost, C445 can remain powered for approximately 200ms
at 70% control power.
1035
Voltage Loss Restart Short
Delay
UINT32 RW NV
Default: 1000
Range: 100 to 500000
Units: ms
Config CRC
Admin Lock
USB Lock
Backup Mem
Voltage Loss Restart Short Delay. If voltage returns to the user specified
level within the short time period C445 will send a command to re-start
the motor after the Short Time Delay.
