No potential separation of the analog inputs to the control voltage!
Malfunction or defect caused by voltage differences.
a) A potential equalizing line between analog value source and analog input is re-
quired if the analog value is outside the common mode range.
b) Connect potential equalizing line with 0V of the control terminal block.
