Interval
Q4F Series
Operating Logic: Upon application of input
voltage the load energizes and the timing cycle
starts. At the completion of the preset time delay,
the load is de-energized. Reset is accomplished by
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 resistoradjustable time delay relays is obtained by shorting 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 watt 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:
Rt =
Note: Due to component tolerances, the
actual time obtained will normally be
within 5% of desired time.
