Diagnostics and servicing

6.1

The instrument is permanently monitored by an internal diagnostic

system. If a malfunction is detected, the respective output signals

change to the safe status (see section "Safe status").

This condition is maintained for at least 1 second. If an error is no

longer detected, the safety function is performed correctly again.

The diagnosis interval is specified in chapter "Safety-related charac-

teristics".

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).

6.2

The procedure is described in the operating instructions manual. Note

the instructions for setup.
