TM3 Series

Operating Logic:  Input voltage is applied to the timer at all times.  Upon closure of a normally open isolated start switch, the load is energized and remains energized as long as the switch is closed.  When the switch is opened, the timing starts.  At the end of the preset time delay, the output is de-energized.  The timer is now ready for a new cycle.
