Information about the operating manual
This manual provides important information on how to work with the device safely and efficiently.
The manual is part of the device and must always be kept in the immediate proximity of the device
so that it is accessible to the personnel at all times.
The personnel must have read and understood this manual before starting any work. Compliance
with all specified safety information and instructions is a basic requirement for safe working condi-
tions.
In addition, the local occupational safety regulations and general safety rules apply for the area of
application of the device.
Due to optional finishing variants, it is possible that the figures shown in this operating manual

Information about explosion protection
Many of our competitors have been marking their products with the Ex symbol as a matter of prin-
ciple for some time now.
At Krautzberger we do not do that.
We engineer and manufacture our products in line with currently applicable directives.
If the labelling on the product is required, it is affixed to the product as the result of the necessary
analysis of ignition sources. If no labelling is affixed, the analysis of ignition sources and previous
experience with the assessment of the suitability of products for use in a potentially explosive area
have shown that the product described in this operating manual does not represent a potential
source of ignition, with the exception of an electrostatic charge.
Taking into account the potential equalisation (provided by proper earth connection), the use in an
area at risk for explosions is permitted in accordance with the currently valid directives.

1 Function and identification
1.1 Function
In conjunction with an extension, the control unit RA 6v is used for:
nautomatic coating/marking of surfaces
ndosing of fluids
nplacement of adhesive or marking points
Typical spray fluids are paints, dyes, adhesives, glazes, enamels, release agents, etc.
The spray fluid is fed into the control unit under pressure. This pressure is typically generated by
pumps or pressure containers. The control unit is operated via compressed air.
For the precise control of the control unit, for example electrically-activated solenoid valves can be
used.
The spray fluid is atomised using compressed air. The geometry of the spray jet and the sprayed
quantity of the spray fluid can be adjusted with the following measures:
nSelection of the air and fluid nozzle for the extension
nChanging of the atomiser air pressure
nChanging of the spray fluid pressure
nAdjustment of the needle stroke on the regulator of the control unit
Optional equipment:
Adapter:
nConnections: From behind (the connections can be made using nipples, screw-type or plug
connectors of different sizes)
nFastening: Plug or screw-type fastening of the adapter
