Cma -s Owner's Manual

 

The AH, B and C Operational Cycle have a total cycle time of 90 seconds.  The Timing 
Diagram and the steps listed below detail the individual functions that are executed during 
each Operational Cycle.

a)  When the door closes the timer assembly motor is energized through the normally 

closed contact of the Start/Stop Relay. 

b)  Within a couple of seconds cams 1 and 2 close their respective switches.  Cam 

switch 1 (Start/Stop) maintains power to the timer assembly motor throughout the 
90-second cycle.  Cam switch 2 (Cycle Reset) energizes the Start/Stop Relay. 

c)  The Start/Stop Relay, once it is energized by cam switch 2, is held in by its own 

normally open contact for as long as the doors remain closed. 

2.  Cam switch 8 controls the pump motor.  The pump motor comes ON at the beginning 

of the operational cycle and continues to run until the end of the drain function 
(controlled by cam switch 3), at which time it turns off for about eight seconds allowing 
time for the machine to refill enough to avoid running the pump dry before the pump 
motor restarts and runs to the completion of the operational cycle.
