8 Vehicle guidance setup Autopilot system
Manual Override Sensitivity calibration
WARNING – Incorrect adjustment of the Manual Override Sensitivity calibration setting could cause this critical
safety feature to fall, resulting in personal injury or damage to the vehicle. Any adjustment to this setting must
be made only by an authorized dealer.
Note – Manual Override Sensitivity calibration is valid only for platforms that employ a pressure transducer
for the manual override function. The software automatically detects whether or not the vehicle configuration
includes this type of sensor and provides this option if required.
Manual override is one method of disengaging the Autopilot system by turning the steering wheel.
When you turn the steering wheel, there is a voltage spike that then tapers off. This spike and
decline occurs at different levels for different models of tractor.
The manual override sensitivity is the level that the voltage must spike to before the override occurs
and the system disengages. The voltage must also taper below that level before automated steering
can be engaged again. If you set a:
l High level of sensitivity, the system will disengage more quickly and you will have to wait longer
before you can re-engage.
l Low level of sensitivity, the system will take longer to disengage and you will be able to re-
engage more quickly.
Incorrect adjustment of the Manual Override Sensitivity calibration setting could cause this critical
safety feature to fail, resulting in personal injury or damage to the vehicle. Any adjustment to this
setting must be made only by an authorized dealer.
We strongly recommend that you perform this calibration only if the default sensitivity is
unacceptable under all conditions. Do not to choose a sensitivity setting that is either too
sensitive or not sensitive enough. In either case, manual override may cease to function correctly.
On some platforms, you could set the sensitivity so low that the manual override function will not
detect any steering wheel motion. It is vital that you avoid this.
Calibration steps
1. At the Vehicle Calibration screen, select Manual Override and tap OK. The Autopilot Manual
Override Calibration screen displays.
2.
Test the current manual override setting. Turn the steering wheel. The Override Inactive button
changes color when the Override becomes active. With the system active, assess whether the
manual override feature is at an acceptable level of sensitivity for:
ll Speed of steering wheel turn
l Distance of steering wheel turn
3.
To adjust the manual override sensitivity setting, move the slider bar.
