5.8.3 Operation
SkySense slows a machine's drive speed to elevated drive speed when it is a certain
distance away from an object, known as the "warning zone." If the machine continues to
approach the object and moves into the "stop zone," SkySense stops all machine
functions.
For proportional functions that are activated by the joystick, the size of the warning
zone varies based on the amount of joystick activation. The stop zone always activates
at the same distance from the object regardless of the joystick's position.
SkySense is active during the following functions:
• Lift Up
• Drive Forward
• Drive Reverse
