calibrated, the console will emit a beep and the AES-25 motor
will stop.
4. Turn the tractor to face in a direction in which you can travel at
least 200 meters/200 yards in a straight line. When the tractor is
moving straight ahead, select next.
The AES-25 electric steering wheel will try to find the exact
straight ahead position. Once this has been found and the vehicle
has driven about 50 meters/yards in this true straight line, the
calibration will complete.
5. The system will begin to save calibration data. Wait until the
screen states that the calibration is completed successfully and
then confirm.
3.5.4. Wheel angle sensor calibration (without AES-25)
Note : This procedure applies to other steering controllers (not the
AES-25) with wheel angle sensor support.
WARNING: Ensure there is sufficient space for the
tractor to drive forward in the center position before
proceeding.
Ensure there is sufficient space for the tractor to
complete the full maneuver before selecting next. The
calibration will take up to 60 seconds in each of these
locked modes.
It is recommended to remove the implement if it is a
trailed, pivoted type implement to avoid possible damage
to the implement or vehicle.
Note
: Wheel angle sensor calibration should be performed once every
6-12 months.
1. From the calibration screen, select the wheel angle sensor
calibration option:
