Menu 3.6.1 Track width
Here the track width can be entered. The track is measured from right
side tyre centre to left side tyre centre of the sprayer wheels. It is
important that the right track width is entered. The controller will
calculate the speed to the centre of machine and not the speed of the
wheel.
If the track width is incorrect, it will influence on track precision and the
safety factor.
Factory setting: 180 cm
Menu 3.6.2 Tractor drawbar
Here the length of the tractor drawbar is entered. The measurement is
from the centre of the tractor rear axle to the centre of the drawbar pin.
This has to be adjusted every time a new tractor is hooked on to the
sprayer. When hooked on, check the rigidity of the tractor drawbar
mounts. There must be no sideways movement.
Factory setting: 80 cm
Too short measurement: The Track reacts faster, but will make the
sprayer steer too large curves.
Too long measurement: The Track reacts slower, but will make the sprayer steer to short curves.
Menu 3.6.3 Dead zone
This is the non regulation zone when the sprayer is straight behind the
tractor. If the sprayer is oscillating in the hydraulics when driving straight,
this value must be increased.
Menu 3.6.4 Damping
IIf the system is to aggressive the damping constant must be increased.
Failure to do so may damage the boom.
Factory setting: 5 cm: Over 15 cm not recommended.
Decreasing value: Reacting on small deviations. Tendency to
oscillate that will damage the boom. High
precision, but more unstable driving with
small corrections all the time.
Increasing value: No oscillation but tendency to sway. Low
precision, but very steady driving with less
corrections.
Factory setting: 50%
No damping (0%): High precision, but very unsteady. Fast
reaction time, but more aggressive
movement that potentially can damage the
boom.
Full damping (100%): Low precision, but very steady. Slow reaction
time, but less aggressive.
