MAR Series Motor Auto-Restart Relay
The MAR series provides automatic restart to a motor by bypassing the start switch to re-energize M1 starter coil following a momentary drop or interruption of the control voltage. When control voltage drops below the under voltage trip point while the motor is running, the under voltage delay begins. If control voltage returns above the restart voltage point before the under voltage delay expires, the adjustable restart delay begins. Upon expiration of the restart delay, the internal relay energizes for the duration of the output interval providing restart. If control voltage fils for longer than the under voltage time delay or the motor was not initially running when control voltage failed, the unit will not restart the motor after restoration of poser. Instead a manual restart is required. This relay distinguishes between control voltage failures and stop pushbutton operations. A stop pushbutton operation de-energizes the output relay and terminates the timing sequences preventing an automatic restart.Features:
