• PREFACE AND SCOPE OF THE MANUAL
This manual contains all information required for assembling and connecting BRAVO computer,
along with instructions for setting up the computer software.
Any other information is given in specic sheets, for the exclusive use of the installation technician,
which contain special information for each model of computer.
• USING THE MANUAL
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.
THIS MANUAL IS FOR USE EXCLUSIVELY BY AUTHORIZED INSTALLATION TECH-
NICIANS.
THE MANUFACTURER IS NOT LIABLE FOR USE OF THIS MANUAL BY UNAUTHORI-
ZED AND UNQUALIFIED PERSONS.
• LIMITS
The description of the installation process refers to a generic computer without reference to specic
models, unless a particular installation procedure applies only a specic type of computer.
• LIABILITY
The installation technician is responsible for implementing the installation procedure in a professio-
nal 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 pro-
vided 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.

1 RISKS AND PRECAUTIONS BEFORE ASSEMBLY
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 che-
micals during simulated treatment runs can seriously injure persons in
the vicinity.
2 BRAVO DSB
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.
3 INTENDED USE
The device you have purchased is a computer which, when connected to a valve or suitable control
unit, makes it possible to control all phases of treatment in agricultural applications directly from
the cab of the agricultural machine in which it is installed.
The apparatus is designed and realised in compliance with the following European
Directives and Harmonized Standards:
- 89/336/EEC and modications
(Electromagnetic Compatibility)
- EN ISO 14982:1998
(Agricultural and forestry machinery - Electromagnetic Compatibility)

5.2 Locating the computer
• BRAVO series computers must be installed in the cab of the tractor, in observance of the following
precautions:
- DO NOT install the computer in an area subject to excessive vibration or collisions
as this may damage it or lead to its controls being accidentally actuated;
- install the unit is a visible position within easy reach by hand: bear in mind that
the computer should not obstruct the operator’s freedom of movement or block his
view.
• Bravo series 32X:
mount the control unit at the rear of the tractor, near to the control and hydraulic units.
Install the four-pole connector running from the control unit to the control panel.
Note the connections required for the computer to operate (table 8 and 10), the
required length of the cables, and provide adequate space for the connectors and
cable runs.
An identication symbol is located next to each connector to indicate its function;
for the conguration of the systems, refer to par. 5.1 - System conguration.
