Error messages in display (starting from firmware V01.40)
Only 1 error can be shown in the display. In the event of an error, the
first line of the display shows an error message and the second line

Please eliminate the cause of the error.
Note!
Acknowledging the error with the "Enter" button on the membrane keyboard causes a soft-

pin 4: Out Ready and Ethernet protocol: "Status".
The sensor starts automatically and is then ready again. An Ethernet connection must be
re-established.
