9.3 Maintenance System
The CNC PILOT reminds the machine user of the required
maintenance and repair tasks. Each action is described in brief form
(assembly, maintenance interval, responsible person, etc.). This
information is shown in the “maintenance and repair jobs“ list. A
comprehensive description of the maintenance action is provided if
desired.
As soon as you acknowledge a completed maintenance measure, the
maintenance interval restarts. The CNC PILOT saves the time of
acknowledgment together with the nominal date in a log file. Service
personnel can evaluate the acknowledgment log files. You can see at
least the last 10 acknowledgments.
Maintenance status: The “traffic light” next to the date/time field
displays the maintenance status. The status with the highest priority
is displayed (red before yellow, yellow before green).
„ Green: No maintenance measures necessary.
„ Yellow: At least one maintenance measure will soon be due.
„ Red: At least one maintenance measure is due or overdue.
„ Prerequisite: The machine tool builder must enter the
required actions and provide complete descriptions of
them.
„ All status changes including the acknowledgment of
maintenance measures are reported to the PLC. Refer
to the machine manual to see whether further
consequences must be made from due or overdue
maintenance actions.
