ACTION LEVEL DISPLAY
Action level display indicates the degree of urgency of the ab-
normality currently generated on the machine by “L01” to “L04”.
The larger the number in the table is, the more serious effects
the abnormality may have on the machine if it is left with no ac-
tion.
If the machine monitor indicates an action level, check the
message displayed on the machine monitor.
By pressing switch F5 on the standard screen while the action
level is displayed, the list of the current abnormality is dis-
played.
Take appropriate actions by following the message displayed
on the machine monitor.
