7.5 Machine height sensor (LLS)

In the menu, set the levels for “Low-lift/Drilling depth” and “output start/output stop”.

Figure 1. Calibration

The system must be calibrated before the different levels can be set; see 7.5.1 Calibrating the machine height sensor (LLS).

  1. Level for LowLift

    Height above ground level is shown as a negative number. The default setting is -10, which corresponds to a Low-Lift height of approx. 10 cm.

  2. Level for seed feed start

    The level at which the seed meter shall begin dispensing seed when the machine is lowered to drilling position. The value is in relation to the drilling depth.

  3. Level for seed feed shut-off

    The level at which the seed meter shall stop dispensing seed when the machine is raised from drilling position. The value is in relation to the drilling depth.

  4. Drilling depth

    The drilling depth is displayed as a positive value, and is greater than the low-lift level.

    The drilling depth is set automatically, and can be adjusted by using function H on the home screen; Figure 1.

  5. Output settings

    Setting the feed output start and feed output stop. See7.5.2 Setting the feed output..

  6. Calibration menu

    Calibrate; see Figure 1.

  7. Current scale value

    Current scale value for the lifting ram.

  8. Current height

    The line indicates current position on the scale.

If you already know which value is to be set for the Low-Lift level or sowing depth, you can do this by pressing on the field that shows the value for the function you want to change. Enter the value in the pop-up window and confirm.

Feed output start and stop are set via (E).

The icons for feed output start or feed output shut-off may never be higher than the icon for the LowLift level or lower than the icon for the drilling depth . The two values may not overlap each other, either.
