To avoid error messages from unused analog input channels, configure them as "unused".
Connection of passive-type analog sensors (Current) to the analog inputs
The following figure shows the connection of passive-type analog sensors (current) to the
analog input AI0. Proceed with the analog inputs AI1 to AI3 in the same way.

CAUTION!
Risk of faulty measurements!
The negative pole 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.
