Differential Input!
For an input signal referred to ground, terminal X10.7 must be connected to reference potential M.
Caution:
The maximum voltage difference between analog input terminals AI+, AI-, and the ground must not exceed 35 V.
<2> Possible settings p0756[0] and p0756[1]:
= 0: Unipolar voltage input (0 V ... +10 V)
= 8: No sensor connected
