The Wash Heater Contactors (HC1, HC2) are energized through the normally open 3CR contacts and the
tank heaters are energized.  The Wash Tank Heaters are now controlled by the tank heat thermostat and
the tank heat high limit thermostat.
The Prewash Fill Valve is energized through the normally closed contacts on the Prewash Fill Switch Relay
(2CR).  The Prewash Fill Valve opens and Prewash Tank starts to fill.  As the Prewash Tank fills the lower
float on the Prewash Tank Float Switch rises and closes it’s switch.  When the Prewash Tank is full the
upper float rises and closes it’s switch.  This energizes 2CR and the relay contacts change state
deenergizing Prewash Fill Valve.
2.  Machine Condition:
Power on, Doors Closed, Tanks Full, Tanks Heated
Starting Sequence:
Start the machine by pressing the Green Start button.  This energizes the Hold In Relay (CR).  If the
Conveyor Switch (CVSW) is closed the drive motor will start and the conveyor belt move.  When CR is
energized the normally open CR contacts close.  The CR contact in parallel with the start button
maintains the CR relay energized.  The CR contacts in the booster heat circuit transfer control of the
booster heaters form the Econo Rinse Fill Switch to the CR relay.  The third set of CR contacts close to
provide a machine running signal.
If the conveyor switch opens the Conveyor Switch Relay (6CR) will deenergize interrupting power to the
Drive Motor Contactor.  This stops the Drive Motor.  Closing the Conveyor Switch reenergizes 6CR and
the Drive Motor starts.
If the Stop Button is pressed the CR relay is deenergized.  This opens the normally open CR contacts.
The Drive Motor contactor is deenergized stopping the drive motor.  The machine running signal
contacts open.  The booster heater contactor control reverts back to the 5CR relay.
3.  Machine Condition:
Power On, Doors Closed, Tanks Full, Tanks Heated,
Drive Running
Timer Operation:
Place soiled ware on the moving conveyor.  As the ware enters the machine the Electric Eye is
triggered and the Electric Eye Relay (EER) is energized. The EER relay is energized only while an
object passes through the Electric Eye.  When the EER normally open contact is closed the Pump
Timer and Rinse Timer are triggered.  The Pump Timer output changes state and the following
components start or become energized:  Prewash Motor, Wash Motor, Rinse Motor, Flushing Valve,
Detergent Signal, Blower Motor, and Heat.
