Section 3 • Theory of Operation First Edition • First Printing
The drive chassis controller (DCON) has no
operator accessible controls. The various steering
controls, axle status, brake and motor speed is
managed by this controller. There are status LED's
on this module to indicate power, data link
communications, system fault and sensor power.
Platform leveling is accomplished with
electrohydraulic controls. An angle sensor is
mounted on the platform rotator which senses the
level of the platform. This signal is processed by
PCON and sent to TCON using the data bus. The
signal from the tilt sensor on the turntable is
compared to the PCON signal and adjustments are
made to level the platform.
For safety, machine drive speed is reduced relative
to the steer angle of the wheels and boom length.
Steering is accomplished using hydraulic cylinders
at each wheel. Correct steering geometry is
maintained through the use of four steering
sensors, one at each wheel. Steering angles are
sent from the primary steering sensor to DCON
and the appropriate adjustments are made to the
other three wheels to correspond with the steer
mode selected. If the machine is equipped with
four wheel steering, there are four steering modes
available: 2 wheel front steer, 2 wheel rear steer, 4
wheel coordinated steer and crab steer. Having
independent control over each wheel allows the
machine to determine the correct wheel geometry
in each steering mode.
Washing electronic components is
not suggested. Instead, use low
pressure compressed air to
remove debris from these
components.
