Warning!
In the case of devices approved for use in explosion hazardous areas, error diagnosis cannot be
performed on the open device as the explosion protection would no longer be guaranteed.

Errors occurring during the self test or during operation are shown immediately on the display.
Acknowledgeable error messages are deleted after pressing a key. A fault is present if the hardware
