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
WARNING
Danger caused by flammable, harmful fluid. Always follow the safety instructions on the con-
tainer or the safety data sheet for the fluid.
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 pro-
tection should be worn, if required.
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!
The valves of the
SMS-11
AUTOMATIC series generally operate with a control air pressure of 3,5 - 6 bar.
Atomized air pressure and material pressure should be closely correlated.
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
2000 mm.
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.
The atomizing air pressure should be controlled in such a way that it starts before the opening of the needle
and stops after the closing of the nozzle (guarantees broadest maintenance-free operation). The valves can
be controlled for intermittent or continuous use. According to the individual application, the control air must
be adjusted to the operating cycles and to the higher or lower material pressures. 40 tacts per second can be
reached under appropriate operating conditions (material pressure, control air pressure, needle stroke, and
short conductions.
For longer standstills, the material can remain in the valve, if it remains under pressure (no contact to outside
air).
