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!

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!
