Soft Lock
If a heat treatment cycle has not been initiated within
the last 24 hours, a soft lock failure will occur. A soft
lock allows the operator to correct the cause of the
soft lock. The operator has the option of either
starting another heat cycle or brush cleaning the
machine. When a soft lock occurs, the machine will
go into the STANDBY mode. The following message
is displayed on the screen. The reason for the soft
lock is indicated on the second line.
NO HEAT CYCLE START
REASON
> HEAT FOR HEAT CYCLE
WASH TO BRUSH CLEAN
If the reason for the soft lock has been corrected,
selecting HEAT CYCLE initiates a Heat Cycle
immediately. Selecting BRUSH CLEAN when the
previous message is displayed will hard lock the
machine and brush cleaning will be necessary.
Following are the variable messages for soft lock
failures that appear on the second line of the screen.

A soft lock can also occur any time during operation
when the hopper or freezing cylinder temperature
rises above 59°F (15°C), the temperature rises and
remains above 45°F(7°C) for more than one hour, or
the temperature rises and remains above 41°F(5°C)
for more than four hours.
If a PRODUCT OVER TEMPERATURE condition
occurs during operation, the following screen will
appear.
PRODUCT OVER TEMP
> HEAT FOR HEAT CYCLE
WASH TO BRUSH CLEAN
When one of these messages appears, automatic
freezer operation cannot take place until the freezer
is disassembled and brush cleaned, or has
completed a heat treatment cycle.
Once the freezer is unlocked by starting a heat
treatment cycle the HEAT key will illuminate and the
following message will be displayed on the screen.
DO NOT DRAW
If BRUSH CLEAN is selected to clear the lockout by
brush cleaning the machine, the FREEZER
LOCKED message will remain on the display until
the brush clean requirements are fulfilled. The
freezer must be disassembled in order to activate
the five minute timer on the display screen. Once
the timer counts down to zero, the lockout is
cleared.
