9.4 Rectify faults
The operator of the system is responsible for taking suitable meas-
ures to rectify faults.
The first measures are:
•
Evaluation of fault messages, for example via the display and
adjustment module
Maintenance
Reaction when malfunc-
tion occurs
Procedure for fault recti-
fication
