Configuring analogue working position sensors

The working position sensor determines whether the implement is in working position. If the implement is in working position, the metering unit can start automatically. When the implement is moved out of the working position, the metering unit is automatically stopped. To determine when the implement is in working position, the positions are specified as a percent value of the total position path. The positions can be taught in.

To determine the total position path of the working position sensor, the limit values need to be taught in.

The following sources can be used for the working position:

  • Sensor on the rear-mounted implement

  • Sensor on the frame of the trailed machine

  • Sensor on the front-mounted hopper

  • Sensor signal from the ISOBUS

Depending on the implement equipment, different switch points can be defined. The switch points define the position of the implement frame in which the metering unit is activated or how far the seeding coulters are lifted on the headlands.

  1. In the Settings menu, select Implement > Working position.

  2. If each metering unit should use its own working position:

    Deactivate Synchronous working position

or

If the same working position should be used for all of the metering units:

Activate Synchronous working position.

If the synchronous working position is activated, a switching state 2 is shown. If the synchronous working position is deactivated, the switching state 1 is assigned to the product.

  1. Under Limit values, continue with
  2. Select the desired sensor under Source.

  3. To teach-in the limit values:

    Press and follow the instructions on the display.

  1. To define the lower limit value:

    Move the implement into working position.

  2. To save the value:

    Press .

  3. To define the upper limit value:

    lift the implement completely.

  4. To save the value:

    Press .

Depending on the implement configuration, a switch point must be configured for the headlands.

  1. Under Switch points, headlands, continue with .

  2. To define the desired switch point for the headland position:

    lift the implement to the desired height.

  3. To save the value:

    Press .
NOTE
If the headland switch point is lower than the product switch point, a message will be shown.
When the message is acknowledged, the product switch points will be reduced. If the message is dismissed, all of the changes will be discarded.
  1. Select the desired product switch point with .
  2. Select the desired sensor under Source.

  3. If the percent values for the switch points are known:

    Enter the percent value for switch points under Switch point metering ON and Switch point metering OFF

or

If the percent values for the switch points are not known:

Follow the instructions on the display under Teach-in switch points.

  1. To define the desired switch-off point for the metering of the product:

    lift the implement to the desired height.

  2. To save the value:

    Press .

  3. To define the desired switch-on point for the metering of the product:

    lift the implement to the desired height.

  4. To save the value:

    Press .
