9.3 Rectify faults
The operator of the system is responsible for taking suitable meas-
ures to rectify faults.
Therstmeasuresare:
•
Evaluation of fault messages via the indicating and adjustment
module
•
Checking the output signal
•
Treatment of measurement errors
FurthercomprehensivediagnosispossibilitiesareoeredbyaPC
withthesoftwarePACTwareandsuitableDTM.
In many case, the failure reasons can thus be determined and faults
rectied.
