Operating Logic: Voltage is applied to the
timer at all times. Upon a closure of a normally open isolated start switch, the output
relay is activated and remains so as long as
the switch is kept closed. When the start
switch is opened, timing starts. At the end
of the preset time delay, the output relay is
deactivated and the timer is ready for a new
cycle.
Note: 1) Do not apply voltage or ground to the start switch; 2)
Switch leads should be shielded when running close to other
wires; 3) If the start switch is reclosed during timing, the timer will
reset and will not start timing until Start switch is opened.
