WARNING:
When Bravo 400S is congured as a GPS GUIDANCE MONITOR (chap. 9) it does not control the valves: any intervention must be
made separately. For valve control see the relevant instruction manual.
The opening / closing of sections must be notied to Bravo 400S with the dedicated switches (par. 12.2) to provide information
on the activity in the eld manually. In this way, Bravo 400S will collect data on the job.

WARNING
When Bravo 400S is congured as a GPS GUIDANCE MONITOR (chap. 9) the switches signal the status of each section
but do not control them: any intervention on the valves must be made separately, by consulting the instruction manual of the
relevant control.
Communicating what happens on the eld, Bravo 400S will collect data on the job.

12.5 Spraying a eld
Let us assume we want to spray a eld
along parallel lines, but only once the
edges of the eld have been sprayed.
Fig.232
• Go the beginning of the eld to be sprayed.
• Switch Bravo 400S on (par 7.2).
After self-diagnostics, Bravo 400S displays
the "Home" screen (Fig. 232).
• Begin a new job, using the function
F3 New job (par. 14.3).
• Enter spraying settings.
When Bravo 400S is congured as a GPS
GUIDANCE MONITOR (chap. 9) the settings
are limited to starting the spraying.

Fig.242
• While moving along the perimeter of the eld, you will mark points A and B
(as described in par. 16.7 F7 New AB).
This operation is fundamental for Bravo 400S to guide you,
during spraying, along tracks parallel to the reference track obtained by
marking points A and B.
We recommend marking points A and B while the machine is
moving, at both ends of a straight line that is as long as possible:
the longer the line marked by points A and B, the lower the error
caused by any deviations of the machine itself.

Fig.243
• Once the line from A to B has been marked (T0), it will be possible to
spray the rest of the eld along parallel lines, (Fig. 243), by following the
reference tracks shown on the display (Fig. 244).

At the beginning of a new job Bravo 400S gives driving directions in the "Straight parallel" mode.

Bravo 400S keeps the set spray rate constant regardless from the changes in speed
and boom section status.
Rate manual regulation shall be carried out with the suitable
switch (par. 12.2).
In this case the spray rate can be set with the function F1 Spray rate (par. 16.1),
or by uploading a prescription map (par. 13.3) from one of the external memories
(SD card or pendrive).
If necessary, during spraying, it is possible to intervene on the dedicated switch
(par. 12.2) to adjust output to crop conditions, increasing
or decreasing momentarily the application rate up to ±50%.

13.3 Importing and using a prescription map
Fig.247
Bravo 400S can vary output by using the data contained in a "prescription map", which indicates
the exact quantity of uid that must be sprayed at every point in the eld.
The map is created thanks to a special analysis and simulation software. The correct spray rate
is established for every point on the map, in order to obtain the optimal yield from a eld with the
minimum expenditure in terms of materials and time.
To enable Bravo 400S to read and use the collected information, the following is required:
- The prescription map must be in " Shapele ESRI® " format.
- The database eld containing the indication of the spray rate that must be applied
to the different areas must be named "Rate".
- The database may include other elds, provided that these contain exclusively numerical
values (the presence of any alphabetic characters will prevent the database from being
imported correctly).
ESRI®isaregisteredtrademarkofESRI,California,USA
At this point you must transfer the prescription map from one of the external memories (SD card or pendrive) onto Bravo 400S:
• Save the map on one of the external memories.
• Copy the map onto the internal memory, through the menu Maps > Copy to internal memory (from SD card par. 14.4.2, or pendrive par. 14.4.3).
• Select one of the functions in the "Home" menu: F1 Continue last job (par. 14.1), F3 New job (par. 14.3) or F5 Resume job (par. 14.5).
• In the job start screen select the desired prescription map.
• Proceed with the job. According to the position detected by the GPS receiver, Bravo 400S will use the appropriate spray rate for the area that is
being sprayed (Fig. 247).
If the tractor is on a "black" area on the map, i.e., without a spray rate indication, Bravo 400S stops spraying.

13.4 How the automatic nozzle selection works (SELETRON system)
In a traditional system, the farming machine speed limits depend on the minimum and maximum pressure of the nozzle in use and on the desired
spray rate.
For instance, if we were spraying 100 l/ha with a violet evenfan nozzle ISO110025, the minimum operating speed shall be 6.9 km/h (corresponding
to a pressure of 1 bar) while maximum speed shall be 13.9 Km/h (corresponding to a pressure of 4 bars).
This operation eld can be restrictive for the features of both crop to be treated and machine.
Operation eld of possible combinations of ISO11002 and ISO110025 nozzles
When automatic nozzle selection is enabled, Bravo 400S (using Seletron devices) will enable the nozzle, or combination of nozzles, according to
the set spray rate and driving speed.
This system allows to widen the machine operating range, i.e. in the above instance, using ISO11002 yellow () and ISO110025 violet () nozzles,
that work correctly at a speed from 5.5 km/h to 24.9 km/h.
Nozzle A
Nozzle B
Fig.248
Fig.249
According to the set data and those detected by the sensors, Bravo 400S selects the suitable nozzle conguration constantly checking that:
- the spraying pressure always remains within the job features set for each single nozzle;
- in case of many possible nozzle congurations, the operating pressure of the conguration in use is as close as possible to the operating range of
the nozzle;
- required number of nozzle changes is as low as possible.
When setting a treatment, make sure to couple compatible nozzles.
Forexample:
• Compatible nozzles:therateat1baroftheISO025nozzleisLOWERthantherateat5barsoftheISO02nozzle(Fig.250).
•NON compatible nozzles:therateat1baroftheISO05nozzleisHIGHERthantherateat5barsoftheISO02nozzle(Fig.251).

Fig.250

Fig.251
In the same way, the overall rate of both nozzles at MINIMUM pressure shall be LOWER than the rate of the high rate nozzle at MAXIMUM pressure.
When setting the treatment (par.12.5 ) Bravo 400S automatically checks the rates and in case the above conditions are not
respected, the computer will display the message Wrong nozzles configuration!
