For the adjustment, Hall sensor 1 with non-controlled(controlled)
solenoid valve 1 is moved into the required position by turning the
adjustment screw 1. The LED Valve Closed lights up.
Openvalvepositionfeedback–sensor2controlled
FortheadjustmentofHallsensor2,atrst,the(non-controlled)
solenoid valve 1 is controlled. This can optionally be made
manually or electrically. The open valve position and the
