In HVAC systems, this unit Provides protection against premature cycling of a compressor. At the end of each operation, or whenever power is lost, a lock delay is initiated which prevents restarting of the compressor. Compressor relay chatter due to thermostat bounce is eliminated by a built-in 1 second "delay-on-make".
Note: The TL Series should not be used with cooling anticipator resistors or solid state switches.
Operation
Lockout: On initial closure of S1, the compressor relay energizes after a 1 second 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.
