This is a description of the operation of the new EUCCW flight machine.  This description was written for
models with a prewash, wash, rinse and econo-rinse section.  Blower operations are also included.  Omit
sequences for models with fewer sections.  Electrical Schematic B701974 is the schematic diagram
used as a reference for this sequence of operation.

          
Initial power up sequence:

Turn on the machine by pressing the Power On/Off switch.  This energizes the control circuit.  The 1CR
(Door Safety) relay energizes.

The Rinse Aid Relay (RAR) is energized through the normally closed contacts on the Econo Rinse Fill
Switch Relay (5CR).  The Final Rinse Fill Valve is energized through the normally open contacts on the
Rinse Aid Relay and the Econo Rinse Tank starts to fill.  As the Econo Rinse Tank fills the lower float on the
Econo Rinse Tank Float Switch rises and closes it’s switch.  When the Econo Rinse Tank is full the upper
float rises and closes it’s switch.  This energizes 5CR and the relay contacts change state.  The RAR is
deenergized closing the Econo Rinse Fill valve.  The Econo Rinse Heater Contactor (HC5) is energized
through the normally open 5CR contacts and the tank heaters are energized.  The Econo Rinse Tank
Heaters are now controlled by the tank heat thermostat and the tank heat high limit thermostat.

When the Econo Rinse Tank fills the Booster Heater Contactors (BC1, BC2, BC3) are also energized
through the 5CR normally open contacts.  Before the Start button is pressed BC1, 2 and 3 are energized
through the normally closed contacts of the Hold In Relay (CR).  The booster heaters are now controlled by
the booster thermostat and the booster high limit thermostat.

The Rinse Fill Valve is energized through the normally closed contacts on the Rinse Fill Switch Relay (4CR).
The Rinse Fill Valve opens and Rinse Tank starts to fill.  As the Rinse Tank fills the lower float on the Rinse
Tank Float Switch rises and closes it’s switch.  When the Rinse Tank is full the upper float rises and closes
it’s switch.  This energizes 4CR and the relay contacts change state.  The Rinse Fill Valve deenergizes
closing the Rinse Fill valve.  The Rinse Heater Contactors (HC3, HC4) are energized through the normally
open 4CR contacts and the tank heaters are energized.  The Rinse Tank Heaters are now controlled by the
tank heat thermostat and the tank heat high limit thermostat.

The Wash Fill Valve is energized through the normally closed contacts on the Wash Fill Switch Relay (3CR).
The Wash Fill Valve opens and Wash Tank starts to fill.  As the Wash Tank fills the lower float on the Wash
Tank Float Switch rises and closes it’s switch.  When the Wash Tank is full the upper float rises and closes
it’s switch.  This energizes 3CR and the relay contacts change state

 deenergizing the Wash Fill valve.
