Systems, Controls and Operations
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 FAULT
DESCRIPTION can also be found in the Manager or
Service Menu (See page 22.)
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. (See Figure 16.)
