PhAse 1

•Lower the SPEED and

FLOW switches

PhAse 2

• Lift the FEEDBACK ON

switch

PhAse 3

•On the Bravo computer enable the

section valves.

The LEDs on the computer

(if present) and LED connectors

must get red.

• Enable automatic regulation

function on the Bravo computer, set

output value and start spraying.

PhAse 4

• Use the SPEED knob to

regulate the speed of the tractor.

If everything works correctly,

the Bravo display will show the

variation of the values relative to

speed and spraying data.

These latter values will be

automatically corrected by Bravo,

using the regulation valve to

compensate for variations in

speed.

PhAse 5

• On the Bravo DSB it will be pos-

sible to check the behaviour of the

regulation valve through the LED

bar in section O (Control Panel).

The LEDs on the bar should switch

on and off to simulate opening

and closing of the regulation valve

during the variations in speed of the

tractor.
