Description
Undervoltage Trip Delay is the time delay following the trip level being
exceeded until a trip occurs.
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.
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).
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.
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.
Voltage Loss Restart Short Time Interval. 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.
