Presentation Transcript

  1. Dozer: Sensors Calibration and Hydraulic Calibration

  2. Pitch Sensor Location • Mount the sensor on the blade • Allow the sensor to rotate 90 degrees for tilt calibration • In this graphic it is positioned in the normal operating position

  3. Pitch Sensor Calibration • Required if AS400 is permanently installed on the machine to measure blade pitch • Park machine on level ground • Make sure the left mast is vertical (if possible) in the forward/aft direction • If it is not possible to make the left mast vertical, put the machine and blade in the normal working position • Press “Calibrate” to zero the pitch sensor.

  5. Pitch Sensor Calibration

  6. Valve Calibration - Basics • Allows smooth automatic control • GCS900 monitors the valve movement and computes a response curve. • Can be done with and without GPS /ATS • Before starting the valve calibration you need to ensure that the machine measurements are entered into the CB430 • The valve calibration should be done with warm oil and at normal operating revs.

  7. Lift Calibration • Must be in Manager mode • Setup / Installation Menu / Valve Calibration • Select “Lift” • A set of screens follow – perform the instructions

  8. Calibration without GPS/ATS • The following screens appear if the GPS/ATS sensors are not detected or due to a low accuracy condition

  9. Calibration without GPS/ATS

  10. Calibration without GPS/ATS

  11. Calibration without GPS/ATS

  12. Calibration with GPS/ATS • Similar screens to previous method without the requirement to measure blade height differences (GPS/ATS does this for you!)

  13. Calibration with GPS/ATS

  14. Calibration with GPS/ATS

  15. Calibration with GPS/ATS

  16. Calibration with GPS/ATS

  17. Calibration with GPS/ATS

  18. Lift Calibration • Place in Auto • Press the Auto/Manual switch • System will then automatically move the blade and monitor the movement against the valve command

  19. Lift Calibration

  20. Lift Calibration

  21. Lift Calibration

  22. Tilt Calibration • Process is similar to the lift calibration • Tilt Calibration requires the AS400 sensor to be rotated 90 degrees to measure the blade tilt

  23. Tilt Calibration

  24. Tilt Calibration

  25. Tilt Calibration
