Delay on Break
Also 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. 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 Littelfuse SSAC 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.
