Troubleshooting
When troubleshooting, begin with the hitch sensors. If you are unable to determine the problem,
proceed with the stick sensor, and then the boom sensor. Note that for the hitch and boom sensors,
there are optional secondary sensors that should be checked if they are used. If you are unable to
determine the problem after following the procedures below, contact Topcon support.
Hitch

1. Position the hitch above the string line so that the bucket teeth or edge are at their closest point
to the string.
2. Place the bucket teeth or edge on the string, and zero the bucket in 3D-MC.
3. Curl only the bucket in and out in various positions, and measure the distance from the string
line to the bucket teeth a with measuring tape (Figure 81).
Figure 81: String Line Verification - Bucket
4. Compare the measuring tape values with those shown in 3D-MC.
5. If the measurements compared against 3D-MC match, there could be an issue with one of the
other sensors; repeat steps 1-4 and reverify.
6. If the measurements compared against 3D-MC still match, check the tilt bucket sensor (if used),
and then follow the steps in “Stick Sensor” below.
7. If the measurements compared against 3D-MC do not match, each sensor must be evaluated for
machine measurement or calibration errors.
