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.

If the reason for the soft lock has been corrected,
selecting HEAT CYCLE initiates a Heat Cycle

machine and brush cleaning will be necessary.
