Adjusting the target pressure difference for the Central Seed Supply and fertiliser

REQUIREMENTS

  • The seed hoppers are filled

  • The machine is unfolded

  • The fan is switched on

  • The singling discs are filled with seed grains

NOTE
The singling pressure is shown on the control terminal. The specified fan pressures are reference values. Check the grain placement after driving a short distance.
  1. Depending on the seed type 2, read the pressure difference 1 from the sticker

or

Determining the seed settings.

WARNING
Risk of injury due to parts of the fan being flung out
If the fan is operated at excessive speeds, fan parts can break and be flung out.
Make sure that the fan speed does not exceed 5.0001/min.
  1. In the Settings menu, select Products > Seed.
  2. Scroll through the menu pages with .

In automatic mode, the target difference between the singling pressure and the Central Seed Supply system pressure is entered. The fan speed is regulated automatically.

  1. To switch on automatic mode:

    Activate the Central Seed Supply automatic function.
  2. Enter the pressure difference under Setpoint difference Central Seed Supply and singling pressure.

The factory setting for the Setpoint pressure difference for empty hopper is 5mbar.

  1. Enter the pressure difference for the empty hopper under Setpoint pressure difference for empty hopper.

  2. To adjust the setpoint pressure difference:

    Press in the Work menu

or

press in the Work menu.

When the setpoint pressure difference is set, the machine data in the Work menu briefly shows the setpoint pressure difference instead of the singling pressure.

During operation, the software sets the Setpoint difference Central Seed Supply and singling pressure value.

When the fertiliser hopper is empty, the software sets the Setpoint pressure difference for empty hopper value.

In manual mode, the fan speed can be infinitely adjusted until the desired target pressure difference between the singling pressure and the Central Seed Supply system pressure is reached.

NOTE
In manual mode, the setpoint pressure difference for empty hopper is not automatically reduced.

  1. To deactivate automatic mode:

    deactivate the Central Seed Supply automatic function.

  2. To adjust the setpoint pressure difference:

    Press in the Work menu

or

press in the Work menu.

When the setpoint pressure difference is set, the machine data in the Work menu briefly shows the setpoint pressure difference instead of the singling pressure.

  1. To monitor the fan:

    Refer to Configuring the fan speed monitoring in the ISOBUS operating manual.
NOTE

If the desired fan pressure is not reached, use a bigger hydraulic motor. For more information, contact your specialist workshop.
