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 function switch “F3” on the standard screen while
the action level is displayed, the list of the current abnormality
is displayed.
Take appropriate actions by following the message displayed
on the machine monitor.
