Soft Lock
If a Heat Treatment cycle has not been initiated within the
last 24 hours, a soft lock failure occurs. 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 goes into the Standby mode. The
following screen appears. The reason for the soft lock is
indicated on the third line.
If the reason for the soft lock has been corrected,
selecting HEAT CYCLE initiates a Heat cycle
immediately. Selecting BRUSH CLEAN hard locks the
machine, and brush-cleaning is necessary.
The following table lists the variable messages for soft
lock failures that appear on the third line of the screen.
Table 5-1
If the following screen appears, a soft lock has occurred
during the Heat Treatment cycle:
A soft lock can also occur anytime 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 1 hour, or the temperature rises
and remains above 41°F (5°C) for more than 4 hours.
If a product over temperature condition occurs during
operation, the following screen appears.
When this screen 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 Cycle key illuminates and the
following message appears on the screen:
If BRUSH CLEAN is selected to clear the lockout by
brush-cleaning the machine, the FREEZER LOCKED
message remains on the display until the brush-clean
requirements are fulfilled. The freezer must be
disassembled to activate the 5-minute timer on the
screen. Once the timer counts down to zero, the lockout
is cleared.
To restore the message that identified the reason for the
soft lock, turn the power switch off for 5 seconds, and
then return the power switch to the ON position. The
original message with the reason for the soft lock
appears.
