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.

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!)

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

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
