Operation
SkySense slows a machine’s function to creep 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 activated by the joystick, the size of
the warning zone varies based on the amount of joystick activa
-
tion. The stop zone always activates at the same distance from
the object regardless of the joystick’s position.
If the function has reached the warning zone, normal drive speed
will resume when a function is activated in the opposite direc
-
tion. If the machine has reached the SkySense stop zone, release
the function and recycle the footswitch to activate a function in
the opposite direction.
SkySense is active during the following functions:
• Lift Up/Down (including jib functions)
• Platform Rotate (including jib rotate)
• Telescope Out
• Swing
• Reverse Drive
