1. Operator control console
The cruise control switch is located on the console arm
the top of the cruise control switch is depressed, the cruise control feature is
off. When the switch is moved to the center position, the cruise control feature
is enabled but no speed is set. When the machine is moving in the forward
direction above the minimum speed and the switch is momentarily moved
downward, the cruise control feature is engaged and the current traction speed
will be maintained.
The slave controller monitors the position of the cruise control switch (off, enable
or engage). The slave controller communicates the switch position to the master
controller via the CAN network. Using inputs from the cruise control switch
and the traction pedal position sensor, the master controller holds the piston
(traction) pump forward control solenoid in its current position. Once engaged,
the cruising speed can be increased (+) or decreased (−) incrementally through
the InfoCenter Display (see
Note: The cruise function is disengaged when the cruise control switch is set to
OFF or if the traction pedal is pressed to the reverse direction.
