OPERATION
A cycle progress pointer oscillates between the ON and OFF time
setpoints. As this pointer crosses the zero point on the dial, two internal
10 amp SPDT output switches transfer. The transfer point of the output
switches is adjustable to allow a make before break (overlap) or a break
before make (dwell) switch action. The overlap or dwell time interval is
limited to 1.5% of the total (ON plus OFF) time cycle.
A synchronous unidirectional motor drives the unit through precision
gearing. Instant reversing of the progress pointer is accomplished by
positive mechanical action.

OPERATION
To Set
Move the black pointer to the desired OFF setting and the orange pointer
to the desired ON setting (as shown in Figure 1). The sum of these ON
and OFF intervals cannot exceed the total time of one scale. Switch
contacts are tripped open or closed each time the indicator pointer
passes 0. When the indicator pointer is in the OFF scale to the left of 0
contacts 4-3 and contacts 6-8 are closed and 4-5 and 6-7 are open.
When the indicator pointer is in the ON scale to the right side of 0
contacts 4-5 and 6-7 are closed and 4-3 and 6-8 are open. The indicator
pointer must travel to the preset limit and back to 0 to complete the total
ON or OFF interval. The two switches can operate together or be set to
allow a break before make (dwell) interval or make before break
(overlap) between ON-OFF switching. Refer to the standard time range
chart under specifications for the maximum dwell or overlap interval for
each time range. Figure 2 illustrates the path of the indicator pointer and
the switch action each time the zero point is passed. Figure 3 illustrates
the terminal location on the rear of the unit case.
