Differential Input!
For an input signal referred to ground, terminal X10.7 must be connected to reference potential M.
Notice:
The voltage between inputs and between input and the ground point must not exceed 35 V. If this is not observed, the input will be damaged.
Possible settings p0756[0] and p0756[1]:
= 0: Unipolar voltage input (0 V ... +10 V)
= 8: No sensor connected
