Operating Logic: Upon application of volt
age to the input terminals, the time delay
cycle starts. At the end of the preset time
delay, the relay coil is energized and the
contacts transfer. Reset is accomplished by
the removal of input voltage.
Note: 1) Remote potentiometer leads should be shielded when
running close to other wires; 2) The minimum time setting on
external resistor-adjustable time delay relays is obtained by short
ing together the external resistor terminals of the relay; 3) The
maximum time setting within tolerance limits is obtained by using
a 1 megohm resistor; 4) Timing values between the minimum
and maximum limits are linear with resistance within 10%; 5)
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.
Consult factory for any special requirements not
listed in catalog (minimum order requirement may
apply).
