Operating Logic: Power is applied to the
timer at all times. Upon a momentary or
maintained closure of a normally open iso
lated start switch, the output is energized
and the time delay starts. At the end of the
preset time delay, the output is de-ener
gized and the unit 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. (Start switch supplied by customer.)
