Voltage Loss Auto
A command to automatically pull a contactor back in to
restart a motor in the event of an undervoltage condition.
No time delay is used in Voltage Loss Restart Auto Time
mode as the voltage dip is considered to be short enough to
avoid out of sync restart of the motor.
Operation
Main Voltage dips below Voltage Loss Level setting.
●
Voltage Loss Level is user-definable but can be set as low
as 65% (default 70%)
●
Contactor may drop out from voltage dip (assuming no 3rd
party device is used to hold it in).
