REQUIREMENTS

  • The hopper is full.

  • The hopper is closed.

  • The calibration flaps are closed.

  1. Read the required fan speed from the table.

  2. If the desired fan speed is lower than 3.0001/min:

    Leave the PTO shaft switched off.
  3. Switch on the red 1 tractor control unit. Set the fan speed to at least 7001/min.

  4. If the desired fan speed is greater than 3.0001/min:

    Switch on the PTO shaft. Set the PTO shaft speed to 8001/min.

  5. To warm up the hydraulic oil for optimal regulation of the hydraulic system and to transport any condensation out of the conveyor section:

    Run the fan for about 5 minutes at 2.5001/min.
NOTE
The set fan speed can drop slightly as soon as the spreading material is routed through the conveyor section.

  1. To correct the fan speed:

    Adjust the oil quantity on the tractor control unit.

The fan speed is displayed on the control terminal.

  1. To monitor the fan:

    Refer to Configuring the fan speed monitoring in the ISOBUS operating manual
NOTE
The pressure difference between the hopper chambers must not exceed 5 when the spreading materials are the same.
  1. Read the hopper internal pressure from the table.
  2. Check the hopper internal pressure on the control terminal.

  3. If the control terminal does not display an appreciable pressure when the fan is running:

    Check if the hopper covers are closed, the seals are undamaged and the sluices are closed.
