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 above 150°F (65.6°C).

COOL = Total time the hopper (h) and barrel (b) temperature was above 41°F (5°C) during the COOL phase.

PEAK = Highest temperature reading for the hopper

(h) and barrel (b) during the Heat Treatment Cycle.

Listed below are variable failure code messages which could appear on line 2.

HT

HEAT TIME FAILURE

 

Mix temperature did not rise above 151_F

 

(66.1_C) in less 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 for UVC3 units or 120

 

minutes for UVC4 units.

TTTOTAL 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

 

present.
