This manual provides instructions to assemble, connect and set the computers of the BRAVO
300S family.
Any other information is provided in specic sheets to be used exclusively by the installer, containing
specic 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 specic 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.
• Do not clean equipment with direct water jets.
• Comply with the specied power voltage (12 Vdc).
• In case of voltaic arc welding, remove connectors from Bravo and disconnect the
power cables.
• Only use ARAG genuine spare parts and accessories.

6.2 Monitor and control unit positioning
Bravo 300S must be placed in the control cabin of the farming machine. Observe the following
precautions:
- DO NOT install the monitor in areas where it would be subjected to excessive
vibrations or shocks, to prevent any damage or accidental use of the control keys;
- Install the device in 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.
• Remote control unit (RCU): secure the remote control unit on the back of the machine, close to
the control unit and the hydraulic unit.
Consider all necessary connections of the computer (Fig. 4), the cable length, and
make sure there is enough space for connectors and cables.
An identication symbol is located next to each connector to indicate its function.
For any reference to the system conguration, read Par. 6.1 - System recommended
composition.

6.3 Bracket xing
The monitor must be mounted after having xed the bracket at the desired location (the previous
paragraph shows the bracket drilling template).
The bracket must be slid out of the monitor seat (, Fig. 6) and xed using the supplied screws ().
Make sure the bracket is securely mounted, t the monitor on it, and push it until it locks in place ().
6.4 Remote control unit (RCU) xing
Respect the mounting direction of the control unit, as specied in Fig. 7 (connectors shall be facing
down).
No other type of assembly is allowed.

6.5 Control unit position
The control unit must be xed with the special brackets supplied and tted to the unit, positioning it
as shown in the manual provided with the assembly.
MAKE SURE TO FOLLOW ALL THE SAFETY INSTRUCTIONS GIVEN IN THE CON-
TROL UNIT’S MANUAL.
6.6 Hydraulic unit positioning
The hydraulic unit must be xed with the special brackets supplied and tted to the unit, positioning
it as shown in the manual provided with the unit.
ARAG IS NOT LIABLE FOR ANY DAMAGE RESULTING FROM THE INSTALLATION BY
UNSKILLED PERSONNEL. ANY SYSTEM DAMAGE CAUSED BY A WRONG INSTALLA-
TION AND/OR CONNECTION AUTOMATICALLY VOIDS THE WARRANTY.
CAUTION! DO NOT CONNECT HYDRAULIC UNITS OTHER THAN THE SPECIFIED
ONES (SEE ARAG GENERAL CATALOGUE).
ARAG IS NOT LIABLE FOR ANY DAMAGE TO THE PRODUCT, MALFUNCTION
ERRORS AND ANY KIND OF RISK IF THE MODULE IS CONNECTED TO NON ORIGI-
NAL UNITS OR UNITS NOT SUPPLIED BY ARAG.

7.1 General precautions for a correct harness position
• Securing the cables:
- secure the harness so that it does not interfere with moving parts;
- route the harnesses so that they can not be damaged or broken by machine movements or twisting.
• Routing the cables to protect against water inltrations:
- the cable branches must ALWAYS be face downwards (Fig. 8a).
• Fitting the cables to the connection points:
- do not force the connectors by pushing too hard or bending them: the contacts may be damaged
and computer operation may be compromised.
Use ONLY the cables and accessories indicated in the catalogue, having technical fe-
atures suitable for the use to be made of them.

7.2 Power supply connection
The package includes the power connector (component 8, Fig. 1) to be connected to the farming
machine battery; Fig. 9c shows the drilling template of the power connector.
Connect the power connector to the battery wires using two 6-mm faston connectors, as indicated
in Figg. 9a and 9b.
Use the cable provided with the package (component 3c, Fig. 1) to connect the computer to the
power supply.
Fi g . 9a Fi g . 9b F i g. 9c
CAUTION:
To avoid short circuits, do not connect the power cables to battery before the instal-
lation is completed.
Before powering up the computer and control unit, make sure the battery voltage is
as specied (12 Vdc).
Bravo 300S is supplied directly by the farming machine battery (12 Vdc): ALWAYS switch on the
computer through the monitor, and then remember to switch it off using the specic key on the
control panel.
If Bravo 300S remains on for a long time with machine off, the tractor battery could
run at: in case of prolonged breaks of the machine with engine off, make sure the
computer is off, too.
The power source must be connected as indicated in Fig. 10: the computer must be connected
directly to the farming machine battery.
DO NOT connect the computer to key-operated switch (15/54).
Fi g . 10
CAUTION:
• The power circuit shall ALWAYS be protected by a
10 A fuse like the ones for automotive applications.
• All cables connected to the battery shall have a
minimum cross-section of 2,5 mm2.
To avoid short-circuits, connect the power cable
connector only after completing installation.
• Use cables with suitable terminals ensuring correct
connection of all wires.
