INTRODUCTION
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 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.
The computer is directly connected to the system by means of two cables connected to the hydraulic and control unit valves and the sensors. In the
cabin you nd all controls necessary to manage the system ensuring great safety during the job.
Bravo 400S LT features a satellite navigator that – through the external GPS receiver – can be used for agricultural applications and navigation.
Bravo 400S LT is not designed for use on public roads and should only be used on farmland.
This device is designed to work on agricultural machinery for spraying and crop spraying applications.
The machine is designed and built in compliance with ISO 14982 standard (Electromagnetic compatibility - Forestry and farming
machines), harmonized with 2004/108/EC Directive.
3 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 400S LT and disconnect the power cables.
• Only use ARAG genuine spare parts and accessories.
• Bravo 400S LT can control hydraulic valves to open / close the boom.
The computer does not feature emergency stop devices: the manufacturer must provide all necessary safety devices for the
hydraulic boom control.
Any time one hydraulic boom section is opened or closed the computer emits an acoustic signal and the display shows the
relevant indication. The manufacturer should also provide acoustic and optical warnings in the vicinity of the boom.

INSTALLATION
5.2 Computer positioning
•The computer series Bravo 400S LT must be placed in the control cabin of the farming machine. Observe the following precautions:
- Do NOT install the computer 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.
Consider all necessary connections of the computer (Fig. 5), 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.

INSTALLATION
6 WIRING CONNECTIONS
WARNING:
To avoid short circuits, do not connect the power cables to battery before the installation is completed.
Before powering up the computer, make sure the tractor battery voltage is as specied (12 VDC).
• Only use ARAG harnesses suitable for Bravo 400S LT computer.
• 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 or animals caused by failure to observe the above instructions.
6.1 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 cannot 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 down (Fig. 7).
Fi g . 7
Fi g . 8
• 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.

Fig. 15 Fig. 16 Fi g . 1 7
WARNING:
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 400S LT 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 400S LT remains on for a long time with the 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. 18: the computer must be connected directly to the farming machine battery.
DO NOT connect the computer to key-operated switch (15/54).
Fig. 18
WARNING:
• 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 sq. mm.
To avoid short-circuits, connect the power cable connector only
after completing installation.
• Use cables with suitable terminals ensuring correct connection
of all wires.
