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