Operating Logic: Input voltage is applied to
the timer at all times. Upon a momentary or
maintained closure of a normally open iso
lated start switch, the load energizes and
the time delay starts. At the end of the pre
set time delay, the load de-energizes and
the timer is ready for a new timing cycle.
(Start switch supplied by customer)
Note: 1) Remote start switch leads should be shielded when running close to other wires; 2) Remote potentiometer leads should
be shielded when running close to other wires; 3) The minimum
time setting on external resistor-adjustable time delay relays is
obtained by shorting together the external resistor terminals of
the relay; 4) The maximum time setting within tolerance limits is
obtained by using a 1 megohm resistor; 5) Timing values between
the minimum and maximum limits are linear with resistance within
10%; 6) Recommend 1/4 W minimum resistor be used.

External Resistance/Time Delay Relationship
1 megohm external resistance is required to obtain
the maximum time for all ranges. To determine the
actual resistance needed to obtain the required time
delay, use the following formula:
Trequired - Tminimum
Rt=
Tmaximum - Tminimum
Note: Due to component tolerances, the actual time
obtained will normally be within 5% of desired time.
