The MAR Series provides automatic restart to a motor. This unit is designed to bypass the start switch to re-energize the M1 starter coil following a momentary drop or interruption of the control voltage. When the control voltage drops below the Under-voltage trip point and the motor is running, the Under-voltage delay begins. If the 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 a restart. If the control voltage remains for longer than the Under-voltage time delay or the motor was not initially running when the control voltage failed, the unit will not restart the motor after the restoration of power. Instead, a manual restart is required. This relay distinguishes between control voltage failures and stops pushbutton operations. A stop pushbutton operation de-energizes the output relay and terminates the timing sequences preventing an automatic restart.
