The TL Series provides protection against short cycling of a compressor. At the end of each operation, or whenever power is lost, a lockout delay is initiated. This lockout delay prevents restarting of the compressor until the head pressure has equalized. Compressor relay chatter due to thermostat bounce is eliminated by use of optional one second delay‑on‑make. The TL Series should not be used with cooling anticipator resistors or solid‑state switches.
Operation (Lockout): Lockout: On initial closure of S1, the compressor relay energizes immediately (or after an optional 1 s delay). When the S1 opens or input voltage is interrupted, the output opens and remains open for the lockout time delay. During this lockout time delay period, the compressor relay cannot be re‑energized. Reset: The lockout time delay cannot be reset. After the time delay is completed, the unit automatically resets.
