This manual contains information reserved for the installation technician, and hence makes use
of technical terminology without the explanations which would otherwise be required by the end
user.
INSTALLATION IS TO BE DONE ONLY BY AUTHORISED AND TRAINED TECHNICAL
STAFF.
THE MANUFACTURER IS NOT LIABLE FOR USE OF THIS MANUAL BY UNAUTHORI-
ZED AND UNQUALIFIED PERSONS.

All assembly steps generally refer to a Bravo computer without mentioning any model, unless a
given installation procedure specically concerns a certain model.
 
The installation technician is responsible for implementing the installation procedure in a professional
manner so as to guarantee perfect functionality of the computer, whether supplied solely with ARAG
components or with components from other manufacturers.
ARAG recommends using its own components for the installation of the control systems.
If the installation technician should decide to use components provided by other manufacturers,
even if this should not require the modication of the cabling or other systems, he does so at his
own exclusive risk and liability.
The installation technician is responsible for compatibility with components and accessories provided
by other manufacturers.
If, as a consequence of the above recommendations, the computer or other ARAG components
installed in combination with components provided by other manufacturers should suffer damage
of any kind, no form of liability, whether direct or indirect, will be recognized by ARAG.

The BRAVO 18x computer family includes spraying computers which control all aspects of product
distribution for agricultural applications.
The computer enables the operator to control the valves and all treatment parameters, both in
automatic and manual mode.
The computers are available in a range of congurations for different numbers of sections and for
connection to various types of sensor.
The computer connects directly to the system thanks to a single cable connection to the control unit
valves and the sensors: the cab installation thus includes only the controls required for controlling
the system, giving total safety in operation.
The BRAVO computer display enables the operator to monitor all the operational data, such as the
speed of the tractor, the amount of product being distributed, the total surface area treated, etc.
 
ARAG has designed and manufactured a diagnostics system for Bravo series computers and the
systems to which they may be connected.
BRAVO DSB (article code 467003) provides reliable computer diagnostics (not of the control unit
to which it is connected) so as to enable the resolution of any potential problems experienced with
the system.

All installation work must be done with the battery disconnected, using suitable
tools and any individual protection equipment deemed necessary.
Use ONLY clean water for treatment tests and simulations: using chemi-
cals during simulated treatment runs can seriously injure persons in the
vicinity.
