Timing Modes Defined

Often called Off Delay, Delay on Release, Delay on De-Energization.Power is continuously applied to the input terminals of the timer. Upon closure of a normally open (N.O.) external initiate switch, the load transfers immediately and remains transferred as long as the external initiate switch is closed. Starting the time delay is deferred by maintained closure of the external initiate switch. The time delay is started instantly by opening the initiate switch. At the end of the delay period, the load de-energizes and the timer is ready for another cycle. Delay time may be reset to beginning, prior to the end of the delay period, by momentarily reclosing (pulsing) the initiate switch.

Current SensorWhen the sensed current increases above or falls below the set-point, the time delay will start. At the end of the delay, the output will be energized.
