Rack Control Module Operation
The timer controls the drive motor, wash pump and the CH66, MD66, I66 prewash pump.
The timer is internal to the RCM. The PUMPS output indicator light shows the RCM Timer is
active.
The timer output comes on when the rack switch opens, this turns on the PUMPS output.
When the rack switch closes the timer counts for 90 seconds.
After 90 seconds, the PUMPS output is turned off.
Inserting another rack during the timing resets the timer to 90 seconds.
The red input lights below show how the RCM inputs affect the timer’s operation,
START light ON - Enables automatic operation
STOP light ON - Disables automatic operation
RACK SWITCH light OFF - Starts the timer
TABLE LIMIT light OFF - Pauses the timer. Timing resumes when the light comes back on.
PAUSE light OFF - Pauses the timer. Timing resumes when the light comes back on.
JAM light OFF - Stops the machine and disables automatic operation. The front panel Start
push button must be pressed to resume automatic operation and a dish rack
must be inserted to start the timer.
