The HEAT CYCLE SUMMARY screen displays the
hours since the l ast heat cycle, the hours since the
product temperature was above 150_F (65.6_C),
and the number of heat cycles completed since the
last brush clean date.

The HEAT CYCLE DATA screen contains a r ecord
of up to 366 heat treatment cycles. The most recent
heat cycle data will be shown first.
Each heat cycle record has three screens. The first
screen displays the month and day of the heat cycle,
the start time and end time, and the fault description.
The bottom line displays the record number and
indicates if a power failure oc curred during the heat
cycle (POWER FAILURE IN HC).

Hopper and bar rel temperature records for each side
of the freezer are displayed in the second and third
screens. The second screen shows the left side (L)
side of the freezer.
The third screen shows the right side (R) of the
freezer.
The top line of these screens shows the hopper (H)
and barrel (B) temperatures recorded at the end of
the Heat Treat Cycle and indicates the side ( L or R)
of the freezer.
The remaining lines indicate the following:
HEAT = Total time for the hopper ( h) and barrel (b)
to reach 150.9°F (66.1°C).
OVER = Total time the hopper ( h) and barrel (b)
temperature was abov e 150°F (65.6°C).
COOL = Total time the hopper (h) and barrel (b)
temperature was abov e 41°F (5°C) during the COOL
phase.
PEAK = Highest temperature reading for the hopper
(h) and barrel ( b) dur ing the Heat Treatment Cycle.

The HEAT time indicates the amount of time taken
in each z one to reach 150.9°F (66.1°C). Each zone
must remain above 150°F (65.6°C) for a minimum o f
35 minutes.
Touch the UP arrow symbol to advance to the next
page or the DOWN arrow symbol to view the
previous page. A Heat Cycle Failure message will
display on the first screen if a failure occurred.
Listed below are v ariable failure c ode messages
which could appear on line 2 .
HT HEAT TIME FAILURE
Mix temperature did not rise abov e 151_F
(66.1_C) in les s than 90 minutes.
CL COOL MODE FAILURE
Mix temperature in the hopper and freezing
cylinder did not fall below 41_F(5_C) in less
than 90 minutes.
TT TOTAL TIME FAILURE
The heat treatment cycle must be completed
in no more than 4 hours.
ML MIX LOW FAILURE
The Heat Phase or Cool Phase time was
exceeded and a mix low condition was p res-
ent.
MO MIX OUT FAILURE
A mix out condition was detected at the start
or during the heat cycle.
BO BEATER OLVD IN HC
A beater overload occurred during the heat
cycle.
HO HPCO IN HEAT CYCLE
A high pressure cut-out condition occurred
during the heat cycle.
