jacking
Closed valve position feedback – sensor 1 controlled
screw
To adjust Hall sensor 1, ensure that the valve is in the closed
position, the solenoid / manual override are not activated. Turn
adjustment screw 1 into the required position. The LED "Valve
Closed" lights up.
Open valve position feedback – sensor 2 controlled
1
To adjust Hall sensor 2, first activate the solenoid valve 1, either
manually or electrically. Then turn adjustment screw 2, to adjust
the open valve position and the corresponding feedback. When it
reaches the required position, the LED "Valve Open" lights up.
Observe the switching hysteresis of the Hall effect sensors!
Therefore, adjust the switch point of the sensors with overlap in
order to permit small variations. We recommend additional 2 x 360°
turns of the adjustment screw.
8. Design with proximity switch holder:

Set the proximity switch holder in position and fasten it with
the screws. Check to see if the "Valve Closed" or "Valve Open"
