4 Description of Function

4.1 Designated Purpose of the Device

CAUTION

The use of other media can cause functional failures, damages or even the destruction of the
device.
Danger from ejected medium under high pressure. Depending on the pressure for
atomization and material, the spraying process can be accompanied by loud noise! We
recommend wearing ear protection.

The AUTOMATIC SMS-11 valve is a pneumatic device and is suitable for the application of greases, oils,
separating agents or colors. It will be opened by control air and will be closed by a needle spring in case of
failure or turn-off of the control air. The spray medium will be supplied into the valve from a pressured
container or via a pump. The separately controlled spray air distributes the material into the actual spray jet,
for which the jet width can be individually adjusted. The discharge from the nozzle will be performed through
the selected special air cap as flat or round jet. Depending on the viscosity of the medium to be applied, the
application result can be individually adjusted through the nozzle size, the atomized air pressure or also the
material supply pressure as well as the jet width settings. Supply of spray air, control air and material is
performed through three hoses, respectively four hoses if the jet width settings are performed vie remote
control. The function of the needle is: opening by air pressure / closing by spring pressure. The SMS-11 is
optionally available with raster-needle sensor and material circulation.

 The SMS-11 is optionally available with raster-needle sensor, nozzle extensions, clamping holder,

quick-change board, heating plate and material circulation.

5 Mounting and Start of Operation

CAUTION

Hazard from ejected medium under high pressure. We highly recommend eye protection.
Depending upon the pressure for atomization and material, the spraying process can be
accompanied by loud noise! If necessary, we recommend ear protection. Only qualified
personnel are authorized to start the operation of the device (see also 2.6 Required
Qualification of Personnel), in accordance with the guiding rules and regulations for safety
and accident prevention.

The valves can be installed in any position. A clamping holder or a quick-change board are available for a
solid installation (optional, see accessories). The distance to the application area depends on the desired
application width.

An intermitting working process of the device will create natural vibrations. Therefore, the installation of the
device has to be solid and firm. Try to avoid extreme natural vibrations (transfer from the machine onto the
valve).

5.1 Hose Mounting

CAUTION

Only use hoses which can be used for the maximum operating pressure of the valve (see
also 4.2 Technical Data).

The three functional hoses will be installed as follows:

5.1 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“.
.

Fig.: wiring diagram

5.1.1 Setting of Sensor (Raster-Needle)

1. The screw-in sensor M4 x 0,5 (2) will be glued with a high-strength screw lock into the sensor holder
over a length of 14.5mm (1).

2. Screw in the regulating spindle (5) until the needle is closed and no more material is discharged from
the nozzle.

3. Connect the sensor to a control unit for adjusting.

4. Then slide the spring (3) and the spindle carrier (4) onto the sensor and together screw in into regu­lating spindle until you receive a signal.

5. Open (unscrew) the regulating spindle until the signal stops (up to max. 8 steps). If the signal of the
sensor hasn’t stopped by then, use the spindle carrier of the sensor for fine-adjustment until the sig­nal stops.

6. The spindle carrier has to be pushed backed against the spring for fine-adjustment so the sensor can
be turned in the regulating spindle until the signal stops.
