GS3 2630 Advanced Settings
CF86321,000027B -19-16MAY11-2/2
Higher settings: Turn the vehicle in a smaller radius
(tighter) around the curve.
Lower settings: Turn the vehicle in a larger radius
around the curve.
Range: 50 to 200.
f. Acquire Sensitivity: Determines how aggressively
the vehicle acquires the track. This setting affects
performance while acquiring the track only.
High settings: Result in more aggressive line
acquisitions.
Lower settings: Result in smoother line acquisitions.
Range: 50 to 200.
5. Follow Tuning Instructions—First try to adjust the
settings based on how it was characterized in Step 2.
If familiar with how the settings affect performance,
proceed to the general tuning instructions if desired.
Although the customer’s comfort needs to be taken
into account, try to tune the tractor based on lateral
error on the GS2 and the tracks that tractor leaves
behind. After nding a reasonable set of parameters,
try running the tractor at different speeds to ensure the
settings are still acceptable. Sometimes the settings
that maximize AutoTrac performance are very close to
making the operator feel uncomfortable.
General Tuning Instructions
Adjustment Recommendations:
•
Steering Sensitivity—Set at 100 before making
other adjustments – after that make adjustments in
increments of 10.
•
Line Sensitivity Tracking—Adjust in increments of 20.
•
Line Sensitivity Heading—Adjust in increments of 10.
•
Heading Lead—Adjust in increments of 10.
•
Steering Response Rate—Adjust in increments of 10.
•
Acquire Sensitivity—Adjust in increments of 20.
•
Curve Sensitivity—Adjust in increments of 20.
One Value at a Time—Attempt to adjust the settings in
the problem eld conditions while AutoTrac is active.
1. Start with the factory default settings. The Steering
Sensitivity value will correlate to the value on the
Guidance View Tap. Attempt to use a value for this
setting that is similar to the conditions in which you are
running (70 for concrete, 100 most conditions, 120
for soft ground). This number may still need to be
modied beyond the suggested settings.
2. While AutoTrac is active in the problem conditions
(speeds, ground, tire setup, etc), increase/reduce the
Line Sensitivity Heading by a factor of 10.
3. If the change in Line Sensitivity Heading is ineffective
at addressing the issue, reset the Line Sensitivity
Heading parameter and increase/reduce the Heading
Lead in the same manner as the previous step.
4. If none of the previous steps were effective reset
the Heading Lead and increase/reduce the Steering
Response Rate in a similar fashion to the previous
steps.
Combining Settings—If the above procedure does not
give satisfactory performance and once you have become
more comfortable with how the parameters change
AutoTrac performance (as detailed in the previous step),
try different combinations of parameters while AutoTrac is
active. The following chart should be used as a reference
and contains suggested values based on various types
of conditions, please note that values may need to be
adjusted beyond these recommendations to achieve
satisfactory performance.
To return all settings to their default values, use the
“Return To Defaults” button provided at the bottom of the
Advanced Settings screen.
