Calibrating the angle sensor
The angle sensor serves to provide feedback
relating to the actual position of the discs or
wheels. Calibration can be performed from the
tab page Wheel Sensor (
), but also in
SBGuidance.
1.
Set both the left and right angle sensor
limits. In wheel control mode, turn the
wheels to their most extreme position
and record the resulting voltages. With
disc control, the left (30%) and the right
(70%) limits must be set tighter. This
prevents the discs from being controlled
far too extreme.
With two cylinder disc control, set the left
and right limits much tighter in order to
avoid synchronization problems.
In the wheel control mode, always set the
left and right limits to their end positions
so that the implement being drawn can
be steered automatically on the line as
quickly as possible.
2.
Determine the centre value of the angle
sensor by turning the discs or wheels to
the straight forward position and by
tapping the Midpoint button.
3.
Check the centre of the disc when testing
in the field. Read the centre of the disc in
the Sensor calibration in SBGuidance
