6 Operation
6.1 General Information
This device may only be operated if the safety-related equipment is permanently effective and not suspend-
ed during operation or altered in its intended effectiveness.
6.2 Operation Instructions / Operating Conditions
CAUTION
Never point the jet at people. The wearing of eye protection is strongly recommended.
The spraying process can create noise depending on the air and fluid pressures used.
Ear protection should be worn, if required.
WARNING
Danger caused by flammable, harmful fluid. Always follow the safety instructions on the
container or the safety data sheet for the fluid.
The valves of the
SMS-18-EH
series generally operate with a control air pressure of 3 - 6 bar. Atomized air
pressure and material pressure should be closely correlated.
6.3 Needle Stroke Settings
The material amount can be set with the stroke regulating spindle (16) as follows:
Function:
Turn to the right: decreasing material amount
Turn to the left:
increasing material amount
IMPORTANT
Accident prevention directions will be
strictly
followed when applying high material
pressures. Please strictly follow the following instructions when planning and
constructing application systems!
Each spraying valve must be equipped with its own pressure regulator for atomizing air.
In case several spraying valves are supplied by one and the same material pressure tank, these
valves must not spray simultaneously.
The supply route for the material between material pressure tank and spraying valve must not exceed
2 m.
If the pause time is a multiple of the spray time, the valve must be sprayed free in a separate location
or the spray valve should be operated several times to optimize the application.
After standstills of 15 min. and more, the valve must be sprayed free by pressing the switch 3 to 5
times.
For longer standstills, the material can remain in the valve, if it remains under pressure (no contact to
outside air.
