This relay distinguishes between control voltagefailures and stop pushbutton operations. Uponexpiration of the restart delay, the internal relay energizes for theduration of the output interval providing restart. If control voltagefils for longer than the under voltage time delay or the motor wasnot initially running when control voltage failed, the unit will notrestart the motor after restoration of poser. Instead a manualrestart is required. Whencontrol voltage drops below the under voltage trip point whilethe motor is running, the under voltage delay begins. If controlvoltage returns above the restart voltage point before the undervoltage delay expires, the adjustable restart delay begins. The MAR series provides automatic restart to a motor by bypassingthe start switch to re-energize M1 starter coil following amomentary drop or interruption of the control voltage. A stop pushbuttonoperation de-energizes the output relay and terminates the timingsequences preventing an automatic restart.
