ential input, i.e. the GND lines of the set-point value
input and the supply voltage are not identical.
Note: If the GND signals of the set-point value input
and the supply voltage are connected, the 3-wire
connection type must be set in the software.
The set-point value input is related to the GND line
of the supply voltage, i.e. setpoint input and supply
voltage have a common GND line.
