OPERATION
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

tion.
If the machine monitor indicates an action level, check the
message of the action level display.
By pressing switch F5 on the standard screen while the action
level is displayed, the list of the Current Abnormality is dis-
played.

tion level display.
