4 PRODUCT FUNCTION
Bravo 13X is an atomizer computer specically designed for treating leafy trees, equipped with numerous control and display functions that can be activated from the driver’s cabin:
• Speed of the vehicle;
• Quantity of liquid distributed on the eld;
• Flow rate;
• Surface area treated (4 partials*);
• Distance traveled (4 partials*);
• Number of trees treated (4 partials*);
• Quantity of liquid sprayed (function equipped with 4 partials*, only enabled in the presence
of a owmeter in the system);
• Level of the tank (function only enabled in the presence of a owmeter in the system);
• Battery voltage;
• Pressure (function enabled only in the presence of a pressure transducer in the system).
The BRAVO 13X main operating principle that differentiates it from other BRAVO family computers is the possibility of identifying the presence of plants on the sides of the tractor through the use of ultrasound sensors and, thus, of only spraying plants and avoiding the waste of chemicals. The BRAVO 132 must be equipped with two ultrasound sensors (mounted at the sides of the tractor) to trip the control unit valves (t wo section valves, one pressure control valve and one drain valve) and increase/decrease the sprayer delivery. The model BRAVO 134 can be equipped with four sensors to detect trees of different heights and to spray only where needed. BRAVO 134 can be connected to control units consisting of four section valves, a pressure control valve and a drain valve.
* By partial we mean a memory area containing data relative to a parameter previou­sly set and stored, which can be recalled at the time of use.

8.1.1 Wheel type
The “WHEEL TYPE” function allows programming and, thus, recalling with a single key, the parame- ters relative to different types of wheels (such as: if they are replaced for different types of crops or if the computer is moved from one agricultural machine to another). This function recalls a parameter, the “WHEEL CONSTANT”, which must be entered as indicated in paragraph 8.1.2 - Wheel constant. Up to 5 types of wheels can be programmed. These are recalled for use by the procedure descri­bed below.
1) Scroll through the functions on the User menu using the and keys and select the
entry “Wheel type”, followed by a number that indicates the active wheel.
2) Conrm the selection by pressing the key: the number that indicates the wheel type will
ash on the display.
3) Change the value using the and keys.
4) Conrm the value set by pressing the key.
8.1.2 Wheel Constant
As the tractor moves forward, the Bravo 13X computer receives signals from the speed sensor installed on one of the wheels. This data is processed on the basis of a value called the “WHEEL
CONSTANT” that must be entered manually or through the automatic insertion function.
The wheel constant set represents the value of the constant relative to the wheel type currently selected: for example, to change the wheel constant that corresponds to wheel type 2, you must rst set the type for wheel 2 following the method shown in paragraph 8.1.1 - Wheel type.
1) Scroll through the functions on the User menu using the and keys and select the entry “WHEEL CONSTANT”, followed by the active value.
2) Conrm the selection by pressing the key: the active setting method appears on the display.
• MANUAL SETTING
To perform the setting using this method, you manually enter the value of the constant after having previously calculated it. The wheel constant can be calculated using the distance that the wheel on which the sensor is installed travels in 10 revolutions (a value to be calculated with the tires inated to working pressure).
The formula for calculating the wheel constant is:
Distance traveled (m) x 10
= ——————————————————
number of magnets
Example:
- Distance traveled in 10 revolutions of the wheel 25,4 m
- Number of magnets installed: 10
The wheel constant is:
25,4 x 10
= ————————————— = 25,4
10
1) Select the Manual setup mode by scrolling the Wheel Constant Menu with the and
keys;
2) Conrm the selection by pressing the key.
3) Change the value using the and keys.
4) Conrm the value set by pressing the key.

Page 12
• AUTOMATIC CALCULATION
BRAVO 13X is able to calculate the wheel constant automatically by using the number of impulses sent by the speed sensor in a straight line of:
- 100 m (EU)
- 300 yards (US)
1) Fill the tank 50% full.
2) Position the tractor at the beginning of the path.
3) Select Automatic calc. by scrolling the Wheel constant menu using the and keys; Conrm the selection by pressing the key.
4) Start and follow the path.
5) At the end of the path, stop and press the key: BRAVO13X will automatically calculate the
wheel constant and display it.
- If the number of impulses received by the computer during automatic calibra-
tion is too low to calculate the wheel constant, the following message displays:
.
In this case, check the installation of the sensor and repeat the procedure. An error can also occur if the wheel has been replaced incorrectly or if the sensor is too far from the magnet. If the problem persists after you have veried that everything is mounted correctly, contact the installer.
- The test must be performed on medium hard ground.
If distribution is carried out on very soft or very hard ground, the difference in rolling diameter could cause an error in the distribution calculation. In this case, it is advisable to repeat the procedure.
End of the wheel constant setting procedure

8.1.3 Product density
The quantity of the products sprayed can vary according to their density. For this reason, the computer allows you to enter a density factor and, thus, to calculate the quantity of liquid effectively sprayed. This value is very important because, if mechanical palette or turbine owmeters are used, since these are affected by variations in the density of the liquid, it could happen that the liquid will be sprayed in a different quantity than that set and measured by the computer. The preset density factor is “1” and it refers to water or, at any rate, a liquid having the same density as water. Since it would be impossible to provide a table with density data for all products that can be sprayed, it is up to the user to evaluate any correction to the entered value that will allow the computer the possibility to exactly indicate the quantity dispensed:
- if, at the end of spraying, the tank still contains liquid, the density factor must be decreased;
- if, on the other hand, the liquid is nished before the end of distribution, the factor must be in­creased.
An electromagnetic owmeter such as the ORION series 462XXX is not affected by the difference in liquid density: for this reason, if this owmeter is present in your system, set the density factor to 1,00.
1) Scroll through the functions on the User menu using the and keys and select the entry “PRODUCT DENSITY”, followed by a number that indicates the value set.
2) Conrm the selection by pressing the key: in this way, the number that indicates the density factor will ash on the display.
3) Change the value on the display by using the and keys.
4) Conrm the value set by pressing the key.
8.1.4 Row distance
The “ROW DISTANCE” function allows programming and recalling with a single key all the para- meters relative to the distances between the rows of trees to be treated, so as to correctly calculate the surface area treated and the volume of liquid sprayed in liters/hectare. Up to 5 types of rows can be programmed: to perform the setting, follow the procedure shown below:
1) Scroll through the functions on the User menu using the and keys and select the entry “ROW DISTANCE”.
2) Conrm the selection by pressing the key. The following information will appear on the display:
AB
A•thetype of row active, indicated by a number
from 1 to 5; B•thevalueofthedistance between rows.
Fi g. 5
3) Select the type of row you wish to set by scrolling to the A value using the and keys; while scrolling, the display will show the distance between rows (B) corresponding to the type of row activated.
4) Conrm the selection by pressing the key: in this way, the number that indicates the distance between rows (B) will ash on the display.
5) Change the value B on the display by using the and keys.
6) Conrm the value set by pressing the key.
ARAG code 46713000.100 ultrasound sensors detect the presence of the plant up to a distance of 6 m.
13
Page 14
8.1.5 Canopy width
Depending on how the ultrasound sensors are moun­ted to the tank or tractor, they will detect either the trunk of the tree or its canopy.
The value to be entered in the computer is the
CANOPY WIDTH”.
If the sensors are oriented towards the canopy, set it to “0”;
if the sensors are oriented towards the trunk, the com­puter must be told how wide the canopy is to open the valves at the correct point for effective spraying. This is done with the following calculation:
width of the canopy in meters (CW) less the dia­meter of the trunk in meters (DT), divided by two:
Fi g. 6
LC – DT
—————
2
Therefore, in case of trees with an average width of 40 cm by the trunk and 3 m by the canopy, the value to be entered is 1,3 m (Fig. 6):
3 - 0,4
= 1,3 m
2
If, on the other hand, the sensors are detecting the canopy and not the trunk, the value to enter will be 0 so that when the canopy is detected, the computer will immediately begin treatment. It is possible to program this function with up to 5 different types of canopy.
To enter the data, follow the procedure shown below:
1) Scroll through the functions on the User menu using the and keys and select the
entry Canopy WIDTH”.
2) Conrm the selection by pressing the key.
The following information will appear on the display:
B A
Fi g. 7
A•thetype of canopy active, indicated by a variable, progressive number up to 5; B•thewidth value for the canopy.
Select the type of canopy you wish to set by scrolling the A value using the and keys;
while scrolling the A value, the display will show the width of the canopy (B) corresponding to the
type of canopy selected.
4) Conrm the selection by pressing the key: in this way, the number that indicates the width
of the canopy (B) will ash on the display.
5) Change the value B on the display by using the and keys .
6) Conrm the value set by pressing the key.

8.3.9 Trees treated
Through this function, BRAVO 13X displays the total number of trees treated.
QUICK RESET: from this menu position, you can directly reset the number of trees treated by simultaneously pressing the and keys for at least 3 seconds. Press the key to conrm the resetting of the value.
Fig. 12a Fig. 12b
The number of trees counted during the treatment will vary depending on whether you are at the beginning or end of a row (Fig. 12a, trees only on one side of the tractor) or inside the rows (F i g . 12b) with trees on both sides of the tractor. During the treatment, the Bravo 13X automatically counts the number of half units per tree treated: for example, in Fig. 12a, when the tractor has treated the rst side of the row, Bravo 13X calculates three trees (corresponding to half the trees effectively present in the row); once it treats the second side, Bravo 13X completely counts the row, in other words, 6 trees. In the event that several rows are treated (Fig. 12b), Bravo 13X counts half the trees in the rst and last row (of six trees it will only count three in the rst row and three in the last), while it will count the complete row when it is between two rows.
8.3.10 Automatic
Through this function, it is possible to display and set the device's operating mode. The BRAVO 13X provides the following types of operation:
• Automatic: the opening and closing of the section valves is determined by ultrasound sensors
installed on the system that detect the presence or absence of the plant to be treated.
• Manual: the opening and closing of the section valves is manually controlled.
• Semi-automatic: the computer operates with some section valves controlled manually and
others controlled automatically through the ultrasound sensors activated.
For any questions regarding conguration of operating modes, consult sec. 9 - Use.
20
Page 21
9 USE
When the tractor is not being used for treatments, make sure that:
• the pump installed in the system is off
• the drain valve is open
Do not stop in front of the sensors, or in their immediate proximity, when they are activated.
Use the Bravo 13X computer ONLY with ARAG units specically designed for this computer: the use of control units, valves or parts connected to the computer other than those mentioned above can cause damage to the device and injury to the user for which ARAG will not be responsible. In the event of damage to the computer or the equipment and sensors connected to it, caused by any of the above, the warran­ty will automatically be considered void.
Using the installed ultrasound sensors, the Bravo 13X computer recognizes the trees to be trea­ted when the tractor moves forward, as a consequence, regulates the opening and closing of the section valves at the right moment, allowing spraying only in the presence of plants and, thus, avoiding product wastes.
Fig. 13
When the computer receives a signal indicating the presence of a tree, it calculates the exact moment to begin treatment on the basis of the speed of the tractor, the distance between sensors and the spraying boom (DSR in Fig.13), and the width of the tree's canopy (LFR in Fig.13).
The computer interrupts spraying by calculating the time necessary to treat the entire tree on the basis of the tractor's speed, the distance between the sensors and the spraying boom (DSR), and the width of the tree's canopy (LFR, set by the operator as indicated in section 8.1.5 - Canopy width).
Bravo 13X can control a minimum of two and a maximum of four section valves, depending on the computer's conguration.
The BRAVO 13X provides the following congurations:

Each sensor can control the opening and closing of one or two section valves at the same time, depending on the system conguration.
In the conguration b, the sensor installed on one side of the tractor simultaneously controls the operation of both the section valves that allow spraying on that side of the tractor.
21
Page 22
The ARAG code 46713000.100 sensors have a range of 6 m, but can be adjusted with the buttons on the sensors themselves.
If the set distance between the sensors and the rows is too great, Bravo 13X may detect targets beyond the trees to be treated and thus also spray when not desired (Fig. 14): to resolve this pro­blem, reduce the sensitivity of the sensors (Fig. 15).
Fig. 14 Fig. 15
All adjustment instructions are given in the manual provided with the sensors themselves.
To perform the treatment, proceed as follows:
1) Go to the beginning of the eld to be treated.
2) Adjust the pressure on the control unit to the minimum by holding down deviator C (Fig. 2 - Control
Panel) for thirty seconds.
3) Correctly select all the values necessary for the treatment (refer to sec. 8.2 - Treatment menu).
4) Select the operating mode you wish to use.
The BRAVO 13X provides the following types of operation:
• Automatic (consult sec. 9.1 - Automatic operating mode)
• Manual (consult sec. 9.2 - Manual operating mode)
• Semi-automatic (consult sec. 9.3 - Semi-automatic operating mode)
5) Go to the beginning of the row to be treated and start the pump.
6) Close the drain valve by pushing control deviator A (Fig.2 - Control Panel) upwards, then keep
going with the tractor and begin treatment.
7) Regulate the pressure (and, then, the dosing) on the control unit to that selected for the treatment by keeping deviator C up (Fig. 2 - Control Panel); check the value of the pressure or the dosing on the display.
8) At the end of each row, open the drain valve by pushing control deviator A (Fig. 2 - Control Panel) downward.
During and after the treatment, DO NOT TOUCH THE SOLENOID SECTION VALVES installed on the system because there is a danger of burns. Before performing any treatment make sure you have set the correct characteristics indispensable for its correct performance: refer to sec. 8 - Setting preliminary to use.
9.1 Automatic operating mode
Before starting automatic mode operation, make sure that the drain valve is OPEN: push control deviator A (Fig. 2 - Control Panel) downward; the display will show the entry "MASTER OFF" (Fig.15-18). The Bravo 13X is set to ALWAYS start-up in manual mode. In automatic operation, the opening and closing of the section valves is determined by the ultrasound sensors installed on the system, which detect the presence or ab­sence of the plant to be treated and enable treatment only if the tractor is in motion.
To set automatic operating mode, proceed as follows:
1) Turn on the device by pressing and holding the key. Bravo 13X will perform the self-dia- gnostics as indicated in sec. 6 - Start-up, then automatically enter the Spraying menu.
2) Scroll through the functions using the and keys and select the entry "AUTOMATIC".
3) Put the ultrasound sensors into operation as described below.

9.2 Manual operating mode
Before performing any operation, make sure that the drain valve is OPEN: position control deviator A (Fig. 2 - Control Panel) downward; the display will show the entry GEN OFF (Fig.15-18).
The Bravo 13X is set to ALWAYS start-up in manual mode.
By turning the BRAVO 13X off and on, you automatically change from any operating mode to manual.
In this mode, the opening and closing of the section valves is manually controlled by the section valve control deviators (B in Fig. 2 - Control Panel):
- to open the section valves, push the corresponding deviators upward;
- to close the section valves, push the corresponding deviators downward.
To enable the operation of the section valves and, thus, perform the treatment, you must position control deviator A (Fig. 2 - Control Panel) upward, so that the drain valve is CLOSED.
9.3 Semi-automatic operating mode
Using this mode, some section valves can be controlled manually through their deviators and others will operate in automatic mode through their respective ultrasound sensors.
To use this mode, you need activate only some of the sensors installed on the system, following the procedure shown below in section 9.1 Automatic operating mode.
To disable the operation of the sensors once they are enabled in automatic mode, just select the sensor to be deactivated by following the same procedure used for putting them into operation.
Example: if you wish to deactivate the operation of sensor S1, for the 2-sensor congurations, press the key; if you wish to deactivate the operation of sensor S1 for the 4-sensor conguration, hold the key and simultaneously press the key.
If all the sensors are disabled, the operating mode will change from semi-automatic to manual mode.
