7 - Menu 3 Calibration
7.13
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.
Factory setting: 2” (5 cm); Over 6” (15 cm) not recommended.
Menu 3.6.4 Damping
If the system is too aggressive, the damping constant must be increased. Failure to do so may damage the boom.
Factory setting: 50%
Menu 3.6.5 Alignment offset
Here the fine tuning of tractor and sprayer alignment is done. This is to compensate if the front potentiometer is placed
offset to the centerline when the sprayer is attached.
Note +/- can be changed with ¿ and ª
Factory setting: 0 %
Negative setting will move the sprayer to the left of the track, and positive setting will move the sprayer to the right of the
track. The sprayer must follow the tractor in a straight line in all situations. If the value is over 4” (10 cm), it is recommended
to manually adjust position of the front angle sensor.
Menu 3.6.6 Sensitivity
The purpose of this menu, is to adapt the track regulation to the tractor
hydraulics and to the characteristics of the sprayer hydraulics system.
Calibration procedure is divided into 4 steps where an offset and gain
value is found to both left and right movement, 4 values in all.
Method:
1.
Unfold boom and, without driving, set P.T.O. to spraying R.P.M.%
2.
Align sprayer and press ® to enable “auto” at the controller. Press
ESC to abort. Press Enter to start calibration of offset and First
left/right offset is found: gain
3.
Go to menu [3.6.6 Sensitivity] and select “Yes” with ¿ or ª and
press #. Press # again and calibration starts.
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.
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.
