The following displays pertain to the HEAT cycle:
Effective 12/8/06, a System Alert screen was added to
display an alert and alarm 15 minutes prior to the start
of the heat cycle. The system alert functions similar to
the Fault Description except there is no menu item.
The alarm will sound and show on the display. The
alarm will sound until the SEL key is pressed to clear
the fault. This feature allows the operator time to make
sure the freezer is in AUTO or STANDBY, and has the
proper amount of mix in the hopper before the start of
the heat cycle.

While in the heating phase, you will see this display. It
shows the present temperature of the hopper.
MODE: HEAT
PHASE: HEAT
HOPPER: 140.0 F
BRUSH CLEAN ON: MM/DD
The mix temperature must be raised above 151
_
F
(66.1
_
C) within 90 minutes or the freezer will be locked
in STANDBY, and the cycle failure display will appear.
In the example, the hopper temperature is 140
_
F
(60
_
C). The phase shows that the machine is in the
heat phase of the heat treatment cycle.
When the heating phase is complete, the freezer goes
into the holding phase of the cycle. The holding phase
will hold the temperature above 151
_
F (66.1
_
C) for a
minimum of 30 minutes.
In this example, the hopper temperature is 151
_
F
(66.1
_
C).
MODE: HEAT
PHASE: HOLD
HOPPER: 151.0 F
BRUSH CLEAN ON: MM/DD
The final phase of the heat treatment cycle is the
cooling phase. Now the freezer must cool the mix
below 41
_
F (5
_
C). If the product fails to cool in two
hours, the freezer will lock out.
This example illustrates that the temperature is being
lowered, but has not yet reached the set point.
MODE: HEAT
PHASE: COOL
HOPPER TEMP: 55.0 F
BRUSH CLEAN ON: MM/DD
The entire heat treatment cycle must be completed in
four hours.
When the entire heat cycle has been completed, the
normal display will appear, showing the machine in the
STANDBY mode. The machine may now be placed in
the AUTO mode or left in the STANDBY mode.
MODE: STANDBY
MIX: OK
HOPPER: 41.0 F
BRUSH CLEAN ON: MM/DD
