Lockout Timer Lockout Timer Lockout Timer Lockout Timer Lockout Timer TL Series HVAC/R Timer Description Description Description Description Description 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. (See the TA Series). Operation Operation Connection Connection Operation Operation Operation Connection Connection Connection Lockout: Lockout: Lockout: On initial closure of S1, the compressor Lockout: Lockout: 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 Lockout Delay--Prevents the lockout time delay. During this lockout time delay Short Cycling of a period, the compressor relay cannot be re-energized. Compressor Reset: Reset: Reset: Reset: Reset: The lockout time delay cannot be reset. After Optional 1 s Delay On Make the time delay is completed, the unit automatically Prevents Contactor Chatter resets.

Less than 15 s will result in proportionally shorter delay periods. NOTE: Cooling anticipator resistor or leakage may cause erratic operation. See TA Series for use with 24 V AC systems that include anticipator resistors or use solid state switches.
