Setting the singling pressure with the tractor control unit

NOTE
To ensure that the singling units on the left and right machine sections are uniformly supplied with air, do not change the settings on the rear air distributor for the machine sections.

PREREQUISITES

  • The seed hoppers must be filled

  • Machine must be unfolded

  • The fertilizer fan is switched off

NOTE
The singling pressure is displayed in the control terminal.
If the desired singling pressure is not reached, use a larger hydraulic motor. Contact your specialist workshop for more information.

Seed

Singling pressure

Beets, rapeseed, sorghum or sunflower

0,51 psi (35mbar) ±0,07 psi (5mbar)

Corn, soy or field beans

0,65 psi (45mbar) ±0,07 psi (5mbar)

  1. Read the setting values from the table.
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. Open the throttle 1 counterclockwise to the stop.

  2. To switch on the singling fan:

    Switch on tractor control unit red 1.

  3. To warm up the hydraulic oil for optimal regulation of the hydraulic system:

    Run the fan for 5 minutes at 3.5001/min.
NOTE
In normal operation the singling disks are automatically populated when the fan is switched on.

  1. To fill the singling disks with seed grains:

    In the Work menu, select .

  2. To correct the singling pressure:

    Adjust the oil quantity on the tractor control unit.

The singling pressure is displayed in the control terminal.

  1. If the pressure gauge 2 shows a pressure greater than 2.175,57 psi (150bar):

    Maintain the throttle setting

or

If the pressure gauge shows a pressure less than 2.175,57 psi (150bar):

Close the throttle clockwise until the pressure gauge shows a pressure of 2.175,57 psi (150bar) to 2.320,6 psi (160bar).

  1. When the throttle has been closed:

    Set the singling pressure again.

  2. When the singling pressure has been set again:

    Correct the throttle setting.

  3. To monitor the fan:

    See Configuring the fan speed monitoring in the ISOBUS operating manual

  4. The values in the table are reference values:

    After driving a short distance check the grain placement.
