ARAG BRAVO130 - Manual (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 specifically 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 warran-
ty will automatically be considered void.
Using the installed ultrasound sensors, the Bravo 13X computer recognizes the trees to be trea-
ted 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 configuration.
The BRAVO 13X provides the following configurations:
CONFIGURATION BRAVO ACCESSORIES UNIT TO CONNECT
a
2 sensors and
2 section valves

Each sensor can control the opening and closing of one or two section valves at the same time,
depending on the system configuration.
In the configuration 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.
