• Power must be applied continuously to timer input voltage terminals and a normally open, dry contact switch attached to timer initiate terminal(s)
• When the initiate switch closes, the timer output relay is energized
• When the initiate switch re-opens the time delay begins

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. Commencement of the time delay is deferred by maintaining closure of the external initiate switch. Opening the initiate switch starts the time delay. 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.
