Timer - Lockout
TL Series
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) .
Connection:
L1
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.

*Power must be applied for at least 15 s to achieve a full lockout delay. Less than 15s will
result in proportionally shorter delay periods.
NOTE: Cooling anticipator resistor or leakage may cause erratic operation. See TA Series
for use with 24VAC systems that include anticipator resistors or use solid-state switches.
