6.1 Behaviour in case of failure
The instrument permanently monitored by an internal diagnostic
system. If a malfunction is detected, a failure signal will be outputted
on the safety-relevant output (see section "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.
If failures 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 dangerous
undetected failure (incl. fault description).
