6 Diagnostics and service
6.1 Behaviour in case of failure
The instrument is permanently monitored by an internal diagnostic
system. If a malfunction is detected, the respective output signals
change to the status configured especially for this condition (see sec-
tion " Safe status ").
The diagnosis interval is specified in chapter " Safety-related charac-
teristics ".
A fault message coded according to the type of fault is outputted. The
fault messages are listed in the operating instructions.
6.2 Repair
If faults are detected, the entire measuring system must be shut down
and the process held in a safe state by other measures.
The manufacturer must be informed of the occurrence of a danger-
ous, undetected error (incl. fault description).
The procedure is described in the operating instructions manual. Note
the instructions for parameter adjustment and setup.
