Lockout
Wiring Diagram
Description
The T2D Series provides protection against short cycling of
compressors and other motors. At the end of each operation, a
lockout delay prevents restarting the compressor or motor until
the delay is completed.
Operation (Lockout with Random Start)
Connection #1: Upon application of input voltage, a random
start time delay begins. At the end of this time delay, the output
is energized.
Lockout Delay: Input voltage must be applied prior to and
during timing. When the thermostat or initiate switch opens,
the output de-energizes and the lockout time delay begins. At
the end of the lockout delay, the output is energized allowing
the load to immediately energize when the initiate switch or
thermostat closes.
Connection #2: Upon application of input voltage and closure
of initiate switch, the time delay begins. At the end of the time
delay, the output is energized and remains energized until power
is removed.
Reset: Removing power resets the output and the time delay.
