Description

Operation (Lockout) On initial closure of the S1, the compressor relay energizes immediately. When S1 opens or input voltage is interrupted, a lockout time delay is initiated. During this lockout time delay, the compressor relay cannot be energized. The low voltage (brownout) protection prevents energization of the compressor when the line voltage is low. Reset: The lockout time delay cannot be reset. After the time delay is completed, the unit automatically resets.
