SECTION 2 - CONTROLS, INSTRUMENTS AND OPERATION

Calibration of the Maximum stubble height

This is necessary to know from which height the area

counter should stop or start counting. When the

header is raised above this level the area counter

assumes you are not cutting any crop. So you have

to put the header at a certain height you will always

exceed when not cutting crop and always stay below

when cutting crop.

Select the height of the header that corresponds to

the description above.

IMPORTANT: If the value is set too low too few area

may be counted since sometimes the header is

raised above this threshold although the combine is

still cutting.

If the value is set too high the area counter will keep

counting even when the header is raised (but below

this threshold) and the combine is not cutting any crop

any more.

To calibrate the maximum stubble height, proceed as

follows:

1. Select the “Maximum Stubble height” calibration

window.

Message:

“Set header to desired maximum

stubble height”.

Message: “Then press enter”.

2. Put the header to the correct position using the

header up or down control switch on the

multifunction handle.

3. Press “enter” to continue or “esc” to exit the

calibration window.

CALIBRATIONS FOR SMARTSTEERt SYSTEM (IF INSTALLED)

The different calibration procedures, in the following

sequence, necessary for good functioning of the

SmartSteert system:

• HGS (Harvester Guidance Sensor)

Turntable actuator calibration

• Straight steer calibration

• Crop edge calibration

• HGS Turntable calibration

IMPORTANT: Check if the following settings are

done to assure correct functioning of the

SmartSteert system.

• Autopilot type: Refer to “VII CONFIGURATIONS

AND CALIBRATIONS“, paragraph headed:

“10.Driveline”

• Longitudinal inclination: Refer to

“VII CONFIGURATIONS AND CALIBRATIONS“,

paragraph headed: “14. Cleaning”

SECTION 2 - CONTROLS, INSTRUMENTS AND OPERATION

Calibration of the HGS Turntable actuator

NOTE: This calibration should be done only when the

SmartSteert system is installed or when a new HGS

turntable actuator is installed on the combine.

IMPORTANT: Before starting the calibration, make

sure the SmartSteert icon is not shown in the upper

left-hand corner of the InfoViewt monitor.

222

NOTE: If the icon is shown then press onto the

SmartSteert rocker switch once to clear the icon

from the screen.

223

1. If ok, select the calibration sub-menu and press

the “right” navigation key to enter the information

box.

2. Select item “HGS Turntable actuator”, using the

navigation key and press “enter”.

Message: “Refer to manual for more information”

Message: “Then press ENTER”

3. Press “enter” to continue or “esc” to abort the

calibration.

Message: “Calibration initiated”

4. The turntable sensor will now be calibrated

automatically. It will turn first to the extreme right

position (CW) and then to the extreme left (CCW)

position, afterwards return to and stop at the

calculated “0 degrees” position.

This is the position where the HGS sensor (2)

(fig. 229) should be looking straight forward in the

driving direction of the combine.

NOTE: This is not the operating position of the

SmartSteert .

226

Message: “Calibration successful”

5. When the InfoViewt monitor indicates that the

calibration has finished successfully, verify that

the HGS sensor 2 (fig. 229) is looking straight

forward.

If not, re-adjust as described in item 8.

227

6. After a successful calibration, the HGS sensor

should look straight forward.

7. The calibration value shown in the “Combine info”

screen, sub-menu “Driveline” should be

0.0 degrees.
