Connection diagrams
If controller and valve receive their power from separate sources, only one
transformer may be earthed on the secondary side.
In case of DC power supply, a 4-wire connection is mandatory!

U
Indication of valve position (only if required). DC 0...10 V → 0...100 % volumetric flow V
100
Twisted pairs. If the lines for AC 24 V power supply and the DC 0...10 V (DC 2...10 V,
DC 4...20 mA) positioning signal are routed separately, the AC 24 V line need not be twisted.
Piping must be connected to potential earth!
Factory setting: Valve characteristics ‘linear’, positioning signal DC 0...10 V.
