Analog input for current measurement range
The pin assignment above applies to X1, X2, X3 and X4.
During parameterization, you specify whether the voltage or the current is to be
measured. This determines whether or not a sensing resistor of 500 Ω is to be
connected in parallel to the input voltage divider.
