Long cable
NOTICE!
Risk of faulty measurements!
The negative pole/ground potential at the sensors must not have too large a
potential difference with respect to ZP (max.
±
1 V within the full signal range).
Make sure that the potential difference never exceeds
±
1 V.

The measuring ranges are described in the section Measuring Ranges
“Parameterization” on page 694
Chapter 1.7.3.1.10 “Measuring ranges” on page 703
.
In order to avoid error messages or long processing times, it is useful to configure unused
analog input channels as "unused".
