• 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 and the time delay begins
• Opening and closing the initiate switch during the time delay is ignored

One Shot

The term “Single Shot” signifies a single pulse output of some duration. Single Shot on Make: Power must be applied to the input voltage terminals continuously. Upon closure of a Normally Open (N.O.) external initiate switch, the load is instantaneously energized and the time delay cycle starts. Maintained closure or actuation of the external initiate switch during the delay cycle will not affect the time delay period. When the delay period expires, the timer will reset to its original position and is ready for another cycle. Single Shot on Break: Power must be applied to the input voltage terminals continuously. Upon closing and opening an external initiate switch, the load is instantaneously energized and the time delay cycle starts. When the delay period expires, the timer will reset to its original position and is ready for another cycle.
