OPERATING INSTRUCTIONS

Confirm the displayed value for the rear potentiometer (19, fig. 10 or 11) with the
OK key.
The values for the potentiometers for
Automatic central position
have now been recalibrated.
In
screen 31
the
dead zone dz
of the potentiometers and the steering response can be adjusted.
The
dead zone
of the rear potentiometer (19, fig. 10 or 11) (at the drawbar or the swivel axle) is a
narrow area where the central position may deviate from the preset central position.
The
dead zone
of the potentiometer at the tractor side (18), that registers the angle between
tractor and drawbar (fig. 9), is a narrow area around the central position of the potentiometer, in
which the potentiometer (18) can be moved by the steer bar (20) without giving a signal to the
jobcomputer.
This prevents many very small steering impulses caused by small movements of potentiometer
resulting from unevenness of the field, small steering actions of the tractor, etc. The dead zone
reduces the wear and oil heating in the hydraulic system and makes the sprayer following more
calmly.
The
dead zone “dz”
of the front potentiometer (18, fig. 9) is factory-set at a value between 8 - 12
and can be modified if necessary, for instance if the drawbar / swivel axle is found to steer too
often or too little.
The
dead zone "dz"
of the rear potentiometer (19, fig. 10 or 11) is factory-set at a value between 2
- 6 and does not have to be modified as a rule.
The values for
gnl
and
gnr
allow you to separately correct the steering degree to the left and to the
right. Dependent on the tractor type, the sprayer type, the way the steering beam is mounted (20,
fig. 9) and the driving speed, it may be necessary to correct the
automatic steering
. At a negative
value, the steering responds stronger to a steering pulse. The sprayer will be running more
outward (outside the tractor track). At a positive value the sprayer will be running more inward
(within the tractor track). Modify these values on the basis of your experience in the field.
