Indication of valve position (only if required). DC 0...10 V → 0...100 % volumetric flow V100
Twisted pairs. If the lines for AC 24 V power supply and the DC 0...10 V (DC 2...10 V,
DC 0... 20 mA, 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!
Ground only one transformer on the secondary side if the controller and valve
are powered separately.
In case of DC power supply, a 4-wire connection is mandatory!
Factory setting: Valve characteristics linear, positioning signal DC 0...10 V. Details see
"Configuration DIL switches", page 4.
See "Calibration", page 5.
