Connection type 3-wire or 4-wire (setting via communication software):
Connection type 4-wire (factory setting)
The set-point value input is designed as a differ-
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.
