How to Install NAVITRONIC Plus® in 10 Easy Steps

Installation of the VÖGELE 3D Machine Control System.

Even a modern 3D Machine Control System can be installed easily. This is what VÖGELE want to demonstrate in the following for NAVITRONIC Plus®. The system installs as easily as it operates. Here you see how to install the system on the machine and prepare it for paving.

Overview of the NAVITRONIC Plus® components to be installed on the paver:

  • Holder for mast
  • Sensor for screed width
  • Magnetic holder
  • Screed operator’s console
  • Sensor for mast inclination
  • Connecting cable

The steps earmarked with this symbol are to be carried out prior to every paver operation. All other steps need to be carried out only once, i.e. when installing NAVITRONIC Plus®.

1 Fitting the Holder for the Mast

The bracket serves as a holder for the mast and the receptor fitted to it. The receptor can be a GPS receiver, laser receiver or prism. See to it that the bracket is positioned above the paver’s augers and aligned parallel with the flange joining screed and screed arm. With some systems, two receptors can be used. In such a case, two masts need to be fitted (left and right sides).

2 Fitting the Sensors

Attach the clamps of the sensors for screed width in the places provided for them using the screws supplied. Important: For initial set-up, the sensors should slide smoothly in the clamps.

Some positioning systems need information on the inclination of the mast. To collect these data, a sensor picking up the inclination needs to be attached to the mast holder.

Then fit the 3D receptor to the mast and attach the mast to the holder. See to tight fit in order to prevent the mast, including receptor, from swaying while paving.

3 Connecting the Cables

Connect the cables before switching on the paver’s ignition. Plug the cable of the sensor for screed width and the one of the sensor for inclination of the mast into the screed operator’s console.

4 Measuring the Mast’s Position (3D Receptor)

In order to create a digital machine model, the precise position of the 3D receptor must be measured in relation to the screed.

5 Defining the Working Range

As a function of the desired pave width, a working range needs to be defined. This should cover the pave width ±40cm (±20cm on either side of the screed).

Example: For a desired pave width of 5.8m, the limits “MAX 6.2m” and “MIN 5.4m” would have to be selected. This working range is necessary in order to correct deviations in the paver’s position from the design route by moving the screed’s extending units in or out.

For the desired pave width of 5.8m described above, the example shows an AB 500-2 Extending Screed fitted with a set of 75cm bolt-on extensions.

6 Setting up the Sensors for Screed Width

Extend the screed to the desired pave width of 5.8m. Then slide the sensors for screed width, guided by the clamps, into place.

The sensors should be positioned in such a way that their measuring range is not left when moving the screed’s extending units in or out. The measuring range is indicated by two marks on the sensor. The sensors must not touch each other when retracting the screed. Then tighten the screws to firmly attach the sensors to the screed.

Now fit the magnetic holders right above the sensors. The clearance between the magnet and the sensor should be 2mm and not exceed a maximum of 4mm.

7 Calibrating Screed Width Control

After installation of the sensors is completed and all cables are connected, the screed needs calibrating. Calibration is necessary every time the screed configuration or sensor position has been changed.

To perform the calibration, just go to the screed operator’s ErgoPlus® console and access the NAVITRONIC Plus® calibration menue. Define the working range, which is your desired pave width ±40cm (±20cm per side). In our example, the range extends from “MIN 5.4m” to “MAX 6.2m”. The working range sets the limits for screed width control.

8 Moving the Paver to the Starting Line

Before moving the paver to the starting line, the external 3D system must have been installed and connected to NAVITRONIC Plus®. Only then is it possible to pick up the paver’s actual position and to calculate the specified position.

The next step is to select, on the display of the paver operator’s ErgoPlus® console, the 3D sensor for automatic steering.

Now the machine’s actual position is displayed on the paver operator’s ErgoPlus® console. He can manoeuvre his machine to the starting line.

The paver should be positioned on the steering line as accurately as possible (±5 to 10cm). In our example, the paver is positioned 10cm to the right of the steering line. Display of a positive value means, the paver’s position is to the right of the line. A negative value indicates a paver position to the left of the line.

9 Setting up the Screed’s Elevation and Width

Now lower down the screed and roughly set the screed’s tow points to the desired height. From this setting, a screed planing angle results. For being able to work with digital data, select “3D” as a grade sensor (use F2 and F4 keys on the screed operator's ErgoPlus® console).

The external positioning system picks up a difference in height and transmits this information to NIVELTRONIC Plus®. The deviation is displayed by the system. It may be necessary to place timber under the screed for height correction until the deviation lies within the range of just millimetres.

10 That’s it ! Mix, please!

When all axes – X, Y and Z – are set up, you can commence paving.
