This manual provides instructions to assemble, connect and set the computers of the BRAVO
300S family.
Any other information is provided in specic sheets to be used exclusively by the installer, containing
specic information of each computer model.
The section of this manual dedicated to the installation contains information for installers. For this
reason we have used technical terms without providing explanations which would be necessary
for end users only.
THE INSTALLATION MUST BE CARRIED OUT BY AUTHORISED AND SKILLED
PERSONNEL ONLY. ARAG IS NOT RESPONSIBLE FOR ANY OPERATION SPECIFIED
IN THIS MANUAL CARRIED OUT BY UNAUTHORISED OR UNSKILLED PERSONNEL.
The descriptions of the assembly phases refer to a "general" computer, so specic models will not
be mentioned, unless a certain installation procedure concerns exclusively one computer type.
The installer must carry out workmanlike installations and ensure to the end user the perfect
operation of the whole system both with ARAG components only and other brands' components.
ARAG always recommends using its components to install control systems.
The installer will be held responsible for any malfunction if he decides to use other brands' compo-
nents even without actually changing the system parts or harness.
The compatibility check with components and accessories of other manufacturers shall be carried
out by the installer.
If the computer or the ARAG components installed together with other brands' components get
damaged because of what stated above, no direct or indirect warranty will be provided.
All installation works must be done with battery disconnected, using suitable tools
and any individual protection equipment deemed necessary.
Use ONLY clean water for treatment tests and simulations: using chemicals during
simulated treatment runs can seriously injure persons in the vicinity.
ARAG has designed and manufactured a diagnostics system for Bravo series computers and the
systems they may be connected to.
BRAVO DSB (Code 467003) provides reliable diagnostics of computer, control unit or the whole
system to troubleshoot any potential problems experienced with the BRAVO DSB system.

Bravo 300S 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 cabin of the
farming machine it is installed in.
This device is designed to work on agricultural machinery for crop spraying applica-
tions.
The machine is designed and built in compliance with EN ISO 14982 standard
(Electromagnetic compatibility - Forestry and farming machines), harmonized with
2004/108/EC Directive.
• Do not aim water jets at the equipment.
• Do not use solvents or fuel to clean the case outer surface.
