the 5-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 third line.
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 third line of the screen.
