Starting an Adjustment

To access adjustment mode, press the ESC and ENTER keys (on the diagnostic display) simultaneously for 3 seconds.

Adjustment mode can be selected from a range of special functions on the diagnostic display by fi rst pressing the PLUS or MINUS key to display the “alignment” item and then pressing ENTER.

Selecting an Axle for Adjustment

Adjustment can only be started if a valid axle number 1 is selected.

Hold down for 3 seconds

On entering a password 0167 (password for Teach In mode only) an angle transmitter can be selected for adjustment. Adjustment must only be carried out by trained personnel. Quit adjustment mode

Axle number-1 Axle number +1 Start adjustment

Press the PLUS or MINUS keys to select an axle. On the present steering system only axle 1 can be selected.

For adjusting steering system SLC 018 305 the following angle transmitters are available:

• Angle transmitter on “axle 1”

Forward Position Axle Adjustment

The angle transmitter is adjusted in 3 stages: • Forward positionadjustment • Left stop and • Right stop

The calculated values are then transferred to the log.

The fi rst line of the display shows the adjustment instructions, the second line shows the voltage readings of the angle transmitter in millivolts.

The axle can be steered with the MINUS and PLUS keys as well as the steering setpoint device. A brief press of the button adjusts the axle at reduced speed. While the key is held down, the steering speed increases proportionally.

If one of the adjustment stages does not occur, the stage can be bypassed by pressing ESC. The previously stored voltages are displayed for control purposes. Pressing ESC again cancels the adjustment of the axle. 0Bypass ° adjustment Steer left

As soon as the selected steering axle is positioned exactly at 0° (and any locking has been applied), the actual value is obtained by pressing ENTER. The actual value must be between 2350 mV and 2650 mV in order to be stored. If the actual value is correct, the current position is recorded. If the actual value is outside the tolerance range, a notice is issued. Press ENTER to repeat this stage or ESC to cancel adjustment of this axle.

Left Stop Axle Adjustment

After adjusting the forward position the user is invited to adjust the left stop.

The selected axle (example: axle 1) is now positioned to the left stop by pressing the MINUS or the PLUS key. When the axle is moved the angle transmitter’s direction of rotation can be checked by the voltage displayed. As soon as the selected steering axle is positioned on the left stop, the actual value of sensor A is recorded by pressing ENTER. To store it, the actual value must be less than 2100 mV and greater than 200 mV.

If the actual value is outside the tolerance range, a notice is issued. Press ENTER to repeat this stage or ESC to cancel adjustment of this axle.

Right Stop Axle Adjustment

The right stop is adjusted in the same way as the left stop. The voltage of sensor A of the angle transmitter must lie between 2900 mV and 4800 mV.

As soon as the selected steering axle is positioned on the right stop, the actual value is recorded by pressing ENTER.

If the actual value is correct, the current position is recorded.

If the actual value is outside the tolerance range, a notice is issued. Press ENTER to repeat this stage or ESC to cancel adjustment of this axle.

Storing the Adjustment Data

The voltages of the angle transmitter have not been fi nally stored in the steering computer. In order to effect the fi nal transfer of the data, the following message must be confi rmed by pressing ENTER.
