If the machine has hard locked and an attempt is
made to enter AUTO, the machine will enter the
STANDBY mode and display the following message.
FREEZER LOCKED
To restore the message that identified the reason for
the hard lock, turn the power switch OFF for five
seconds and then return the power switch to the ON
position. The original message with the reason for
the Hard Lock will be displayed.
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.
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

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.
