Technicians Only: Freeze Cycle Sequence of Operation
This sequence begins with a restart after the unit
has shut off with the bin full. Ice has been
consumed, causing the ice sensors to become
un-blocked.
1. The controller (four minutes has to have passed
since the machine shut off on bin full for the
machine to restart)
2. The purge valve is opened and the pump
started.
3. After the purge valve closes the inlet water valve
opens and fills the reservoir.
Note: If the water reservoir does not fill within the
time period expected the controller will shut off and
switch on the water indicator light. It will re-try to fill
the reservoir in 20 minutes. If successful the freeze
cycle will continue.
4. The compressor and fan motor start and the
freezing process begins.
Note: The controller is
connected to two external
relays in the EH222, one
for the CP's compressor
contactor and the other
for the CP's solenoid
valves. A separate 24 volt
transformer is in the CP
supplying power to the
contacts of these two line
voltage relays through the
interconnecting wire.
5. The controller will shut
the water pump off for a
few seconds when the
reservoir's water
temperature reaches a
pre-set point.
6. The freeze cycle
continues until water
makes continuous contact
with the ice thickness
sensor. That signals the
controller to terminate the
freeze cycle and begin
the harvest cycle. The
Water Schematic
Ready to Harvest light will
be ON.
