Setting the target pressure differential for Central Seed Supply and fertilizer

PREREQUISITES

  • The seed hoppers must be filled

  • Machine must be unfolded

  • Fan must be switched on

  • The singling disks must be filled with seed grains

NOTE
The singling pressure is displayed in the control terminal. The specified values 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 ejected fan parts
If the fan is operated at excessive speeds, fan parts can break and be ejected.
Ensure 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 .

The target differential between the Central Seed Supply System pressure and the singling pressure is entered in automatic mode. The fan speed is regulated automatically.

  1. To switch on automatic mode:

    Activate the Central Seed Supply automation.
  2. Enter the pressure difference under Target difference Central Seed Supply and singling pressure.

The factory setting for the target pressure difference with empty hopper is 0,07 psi (5mbar).

  1. Enter the target pressure difference for the empty hopper under Target pressure difference with empty hopper.

  2. To adjust the target pressure difference:

    Press in the Work menu

or

Press in the Work menu.

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

In operation the software sets the value Target difference Central Seed Supply and singling pressure.

If the fertilizer hopper is empty the software sets the value Target pressure difference with empty hopper.

In manual mode, the fan speed can be variably adjusted until the desired setpoint differential between singling pressure and the Central Seed Supply System pressure is reached.

NOTE
In manual mode the target pressure difference with automatic hopper is not reduced automatically.

  1. To deactivate automatic mode:

    Deactivate the Central Seed Supply automation.

  2. To adjust the target pressure difference:

    Press in the Work menu

or

Press in the Work menu.

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

  1. To monitor the fan:

    See Configuring the fan speed monitoring in the ISOBUS operating manual.
NOTE

If the desired fan pressure is not reached, use a larger hydraulic motor. Contact your specialist workshop for more information.
