Terminal Block
“USE COPPER WIRES ONLY”
Tightening torque 15 in-lb.
The following example shows the
clock set to 2:30 PM.
Turn the outer dial clockwise
until the inner clock hands
point to the correct time.
Each tick mark on the outer
dial represents 15 minutes.
The inner dial is representative
of conventional clock, with the
printed “hand” showing the hour
and the physical hand showing the
minute. The time displayed on the inner dial will always
correspond with the time on the outer dial.
To Set the Current Time
Determine the appropriate cycle
time for your application. Next,
set the switches for each 15
minute interval you require
by moving the switch to the
outer position.
Each switch represents a 15
minute interval and there are
4 intervals per hour.
In this example, the system will
begin one timed cycle at 5:00 PM,
which will last for 45 minutes (3 intervals).
The unit will resume normal operation at 5:45 PM.
If multiple cycles are required, please select the appropriate
dipswitches to represent each 15 minute interval throughout
the 24 hour period where desired.
