12 Troubleshooting
The unit has many self-diagnostic options. It monitors itself automatically during operation.
Warnings and error states are displayed even if the display is switched off. Error indications are also
available via IO-Link.
The status signals are classified according to NAMUR recommendation NE107.
If several diagnostic events occur simultaneously, only the diagnostic message of the event with the
highest priority is displayed.
If the measured temperature value fails, the process value for flow rate is still available.
Additional diagnostic functions are available via IO-Link
