Check the valve position indicators:
Closed valve position feedback – sensor 1 controlled
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
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” message appears. Re-position the proximity
switch if required.
