HOW TO CALIBRATE HE400 AND HE500 VGT ACTUATORS

Actuators play a key role in boost pressure control.
In some cases, however, these components cannot be installed without specific calibration, which is essential to ensure proper operation.

Different types of actuators, such as those for the HE400 and HE500 VGT turbochargers for VOLVO/DAF applications, require dedicated configuration. In these situations, standard flushing tools are not always suitable for calibration. Often, these tools:

• • Do not support the advanced protocols required by modern actuators;
  • Do not allow you to set the necessary reference parameters;
  • Do not perform guided calibration sequences;
  • Do not read or reset stored information.

In essence, while useful for basic checks, these tools are not always able to bring an actuator to the required operating configurations.

To ensure correct and reliable results, DEPROS provides, where necessary, a dedicated calibration tool when these specific items are purchased. The tool allows you to:

• • Connect to the actuator correctly and safely;
  • Set the exact reference positions;
  • Perform the complete calibration procedure following the required protocols;
  • Ensure that the actuator operates with optimal precision from the first use.

Calibration is performed by connecting the actuator to the supplied tool, which guides you step by step through adjusting the positions and saving the correct parameters. Once completed, you can immediately verify the correct operation of the component.

To support our customers, we have created a video demonstrating all the calibration steps using the dedicated tool:

Conclusion

Actuator calibration is a crucial step to ensure the correct operation and safety of the vehicle. Since many actuators require specific configurations, thanks to the calibration tool and the visual support provided by the video, the procedure can be performed simply, correctly and safely.
