1) To assure safety when a trouble is sensed, the machine is
stopped simultaneously.
U4-02, OWF2-33,
3WFW8-01 ,02
POWER OFF-ON
2) To minimize machine damage, when a trouble is sensed, the
machine is stopped simultaneously.
3) To Wow the enct area of the machine where the trouble occured
by using trouble codes, thereby shotiening the recove~ time of
the machine. (For improved repair efficiency, tie repair parts
should be arranged in advance.)
