Adjustment procedure:
- Switch to input mode by pressing the OK key ; the value on the left (front potentiometer (18, fig.
9) on screen 31 will be blinking .
-
Press arrow key until you reach the value to be changed. Then this value is blinking.
-
Change the value with the arrow keys and as desired and confirm with the OK key . The
next value will be blinking.
- Change this value, if required, with the arrow keys and press the OK key or press the
arrow key until you pass the last value in the screen and the next screen is displayed.
In
screen 32 the maximum steering deflection and the steering delay can be set.
Note: Only set or modify the value for the maximum steering deflection for a track width below
(<) 1.80 m. For a track width of 1.80 m of more, the steering deflection must be as large
as possible.
Limiting the steering deflection will prevent damage to the machine, for instance due to the sprayer
wheels touching the tank.
Procedure for setting the steering deflection
- Calibrate the central position of the potentiometers according to the procedure described
above.
- Move the drawbar/axle to the central position using Automatic central position .
- Switch to input mode by pressing the OK key; the value of the rear potentiometer (19, fig. 10
or 11) and maximum steering deflection is blinking .
- Put the drawbar/swivel axle steering to manual operation by pushing down the switch .
- With the tractor stopped: manually steer the drawbar/axle with the aid of the switch
until the desired maximum steering deflection has been reached. For the swivel axle steering
you should allow a safety margin of a few centimetres between wheel and tank.
Note: Steer once to the left as well as to the right until the desired maximum steering
deflection has been reached. Select the lowest value if these values are not equal!
- The value of potentiometer at the desired steering angle now blinks on the screen. Press the
OK key to confirm the value.
If the sprayer is equipped with automatic swivel axle steering, you can also program a path-
dependent delay in
screen 32 . This will prevent that at a steering movement of the tractor, the
swivel axle is directly steered out and the wheels are steered out of the tractor track. The
necessary delay depends on the position of the swivel axle, the driving speed and the response
time of the hydraulic system. The value for the delay is factory set at:
∆ D = 0.50 for swivel axle
steering.
Note: for drawbar steering the value must not be changed and it must be ∆ D = 0.00 !
The optimum value can be determined by taking a few turns in the field and checking whether the
sprayer wheels start steering at the right moment.
