5 Initial Start-up
5.1 Installation
The valves can be installed in any position. The distance to the surface to be applied with the medium
depends on the spray pattern.
Vibrations of the valve caused by fast intermitting cycles require solid and tight installation. Machine
vibrations to the valves should be avoided.
5.2 Hose Connection
The two function hoses are to be connected as fol-
lows:
1 control air to plug connection for 6mm hose
(11.0)
2 medium to 1/8"-connection (can be ordered
as accessories)
5.3 Adjustment of the Incomplete Device
The amount of material can be regulated via the stroke adjustment of the needle (7.0). A left turn of the regu-
lating knob increases the material amount. A fine precision thread affects a needle rise that results in an
adjustment of 0.5mm with each turn of the adjusting knob.
IMPORTANT
Do not turn the regulating knob further to the left if no more stops are noticeable while turn-
ing it! The maximum fluid outlet has been reached.
IMPORTANT
Nozzle and needle can be damaged by wrong handling. Only decrease the material flow by
a right turn of the regulating knob.
5.4 Raster-Needle Sensor
Optionally, you can use a raster-needle lock with a pre-installed, inductive proximity switch. It will release a
signal when the needle piston with the needle is open. This will help you in digitally monitoring the status
„nozzle open“.
