TL120A5T工業(yè)自動化與控制的延時繼電器規(guī)格書PDF中文資料

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.
