3.5 Steering calibrations

3.5.2. Compass calibration

Drive to a place that will not interfere with the calibration before

beginning. This should be away from high voltage power lines and

large metal objects, with space to drive in complete circles.

1. From the calibration screen, select the compass calibration option:

 X30: COMPASS

 Universal terminal:

If the compass reports as calibrated, still complete the calibration

procedure.

2. Read the screen and find an appropriate flat place away from high

voltage power lines and large metal objects. Then select next.

3. Drive the vehicle in a circle at approximately 75% of full lock,

the direction does not matter. Once 1 and ½ turns have been

completed, stop and select next.

4. Drive the vehicle straight ahead for approximately 100 m / 100

yards then STOP the vehicle. Select next.

5. The system will begin to save calibration data. Wait until the

screen states that the calibration is completed successfully and

then confirm.

3.5.3. Wheel angle sensor calibration (with AES-25 and

Fendt FSC)

Note: This procedure is the same for calibrating AES-25 wheel angle

sensor and Fendt Steering Controller (FSC), but the hydraulics actuate

instead of the steering wheel moving for the FSC.

Note: Wheel angle sensor calibration should be performed once every

6-12 months.
