1.
With the machine powered up, toggling the START switch begins a cycle.
a)
Toggling the START switch energizes both the Cam Timer motor and the Instant Start
Relay. The Instant Start Relay latches ON the power to the Cam Timer motor so that
the START switch can be released a moment after it has been toggled without the Cam
Timer motor losing power.
b)
After about 1.5 seconds the Cam Timer’s first cam—the Cam Timer Motor Cam—
latches ON the power to the Cam Timer motor and drops out the Instant Start Relay.
The Cam Timer motor continues to run for a total of 3 minutes, at which time it
switches OFF—resetting the Cam Timer—and waits for the next START command.
2.
The Cam Timer’s third cam controls the Wash Pump. The Wash Pump comes ON about 3
seconds into the Operational Cycle and continues to run for 96 seconds. This 96-second
period is the Wash Cycle.
