Random Start
Plus Lockout
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. 24VAC models can be used with
thermostats that include a cooling anticipator
resistor. It can be connected in series with the load
for delay-on-make operation.
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.
