INTRODUCTION
• MANUAL FOREWORD AND USE
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.
• MANUAL USE MODES
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. THE MANUFACTURER IS NOT
RESPONSIBLE FOR ANY OPERATION SPECIFIED IN THIS MANUAL CARRIED OUT BY UNAUTHORISED OR UNSKILLED PER-
SONNEL.
• LIMITATIONS
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.
• RESPONSIBILITY
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' components 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.

INSTALLATION
1 RISKS AND PROTECTIONS BEFORE ASSEMBLY
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.
2 BRAVO DSB
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.
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 cabin of the farming machine it is installed in.
This device is designed to work on agricultural machinery for crop spraying applications.
The machine is designed and built in compliance with EN ISO 14982 standard (Electromagnetic compatibility - Forestry and
farming machines), harmonized with 2014/30/UE Directive.
4 PRECAUTIONS
• 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.

INSTALLATION

6.2 Monitor position
The Bravo 300S series computer 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 opera-
tor’s freedom of movement or block his view.
Consider all necessary connections of the computer (Fig. 3), 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 (A, Fig. 4) and xed using the supplied screws (B).
Make sure the bracket is securely mounted, t the monitor on it, and push it until it locks in place (C).
Fi g . 4
6.4 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 CONTROL UNIT’S MANUAL.

7 COMPUTER CONNECTION TO THE FARMING MACHINE
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. 5a).
Fig. 5a Fig. 5b
• 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 features suitable for the use to be made of
them.
7.2 Power supply connection
The package includes the power connector (component 6, Fig. 1) to be connected to the farming machine battery; Fig. 6c 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. 6a and 6b.
Use the cable provided with the package (component 3, Fig. 1) to connect the computer to the power supply.
Fig. 6a Fig. 6b Fig. 6c
CAUTION:
To avoid short circuits, do not connect the power cables to battery before the installation 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. 7: the computer must be connected directly to the farming machine battery.
DO NOT connect the computer to key-operated switch (15/54).
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.

8 CONNECTING THE CABLE TO THE CONTROL UNIT AND SERVICES
• Use only the cables provided with the ARAG computers.
• Take care not to break, pull, tear or cut the cables.
• Use of unsuitable cables not provided by ARAG automatically voids the warranty.
• ARAG is not liable for damages to the equipment, persons, animals or things caused by failure to observe the above instruc-
tions.
8.1 Connecting the multi-pin connector
Connect the multi-pin connector to the panel (item 1, Fig. 3) and connect the other end of its cable to the control unit. Make sure that it is correctly
tted and turn the collar clockwise until it locks in place.
8.2 Connecting the control unit valves
• Use ARAG valves: use of unsuitable valves not provided by ARAG automatically voids the warranty.
ARAG is not liable for damages to the equipment, persons, animals or things caused by failure to observe the above instructions.
• All valve connectors must be provided with seals before being connected (Fig. 8).
• Make sure the seals are correctly tted to avoid water inltration when using the control unit.

Connector 1shall control the valve which in turn is
connected to the boom section 1, and so on with
the other valves.
Connect "connector 1" to "valve 1", and then the
other connectors, with rising numbers from left to
right: the boom section 1 is the left one looking
the machine from the rear side (Fig. 7).
Fi g . 8
Fix the connectors to the relevant valves according
to the initials indicated in your assembly general dia-
gram (Par.6.1 - System recommended composition).
• Remove the protection cap (1, Fig. 8) from the
electric valve.
• Place the seal (2) onto the connector (3) and push
the connector fully on (4): be careful not to bend
the contacts upon insertion on the valve.
• Tighten the screw (5) fully home.
If the number of monitor switches is greater than the number of section valves, connect cables as specied in Table 1b.
