TL120A5T规格书详情
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 (Lockout)
Lockout: On initial closure of S1, the compressor relay energizes
immediately (or after an optional 1s 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.
