The second screen will have the same page number
and display the temperature recorded in each
hopper, barrel, and the temperature of the glycol
when the heat cycle was terminated. The left hopper
and barrel temperature is displayed on line 2 and the
right side temperatures on are line 3. The time in the
last phase of heat cycle, whether successful or
failed, is displayed on line 4.

Listed below are variable failure code messages
which could appear on line 2.
HT Heat Time Too Long
Mix temperature did not rise above 151°F
(66.1°C) in less than 90 minutes.
CL Cool Time Too Long
Mix temperature in the hopper and freezing
cylinder did not fall below 41°F(5°C) in less
than 120 minutes.
TT Total Time Too Long
The heat treatment cycle must be completed
in no more than 4 hours.
MO Mix Out Condition
A mix out condition was detected at the start
or during the heat cycle.
ML Mix Low Condition
The Heat Phase or Cool Phase time was
exceeded and a mix low condition was
present.
BO Beater Overload Condition
A beater overload occurred during the heat
cycle.
HO High Pressure Cut-Out Condition
A high pressure cut-out condition occurred
during the heat cycle.
PF Power Failure
A power failure caused the Heat Phase,
Cool Phase, or Total Cycle Time to exceed
the maximum allowed time. If a power failure
occurs, but the heat treatment cycle does
not fail, an asterisk(*) will appear on the third
line of the display.
PS Power Switch OFF
The power switch was placed into the OFF
position during the heat cycle.
TH Thermistor Switch OFF
A thermistor probe has failed.
RC Record Cleared
Data has not been written to the page or
cleared due to corrupt data.
OP Operator Abort
Indicates the heat cycle was aborted in the
OPERATOR ABORT option in the service
menu.
PD Product Door Not in Place
A product door is not in place or is loose.
