LeeBoy 8510E - Plus One Controller; Driving the Paver

4-18 LeeBoy 8510E Conveyor Paver
Operation
Driving the Paver
The dual operator platforms allow easy and convenient
access for controls of most paver functions. The paver
is typically operated from the left side of the operator
platform, but it can also be operated from the right side
for your convenience. Multiple switches, levers and
dials allow the operators to control all paving functions.
NOTE: The Emergency Stop button on the main
operator console is used to shut down the engine
and all paver functions in the event of an emergency.
A steering and speed control box with dual joysticks
are located on each side of the platform. An optional
steering wheel control box is also available.
Ensure there are no people, obstacles
or other equipment in the path of the paver before
moving in either direction.
Figure 4-31. Operator Control Station
NEVER leave the operator station
unattended while the paver is in gear or in motion.
Operator must return joystick(s) to the neutral
position and turn the RUN/STOP switch to the STOP
position before leaving the operator platform.
NOTE: The engine will not start unless the E-STOP
button is disengaged, the Run/Stop switch
is in the RUN (center) position, and the
joysticks must be in the NEUTRAL (center)
position.
Plus One Controller
The Plus One is a 50-pin controller operating in the
background that monitors paver control systems and
alerts the operator in the event of a fault. When the
Plus One controller senses a system fault, the Plus
One light on the control panel (Figure 4-30) illuminates
green and blinks continuously or blinks, then pauses,
then blinks again. A complete list of fault codes with
corrective action messages are shown in Section 5,
Troubleshooting.
Plus One Light
Figure 4-30. Plus One Light
When the key is turned on, the Plus One light will
illuminate for approximately three seconds while the
controller powers up, then turn off when the machine
is ready to start. The Plus One will not allow the engine
to start if any joystick is out of neutral or more than one
Run/Stop switch is in the RUN position.
These faults will prevent machine movement:
• Steering control box not detected.
• Joystick(s) not in neutral at start-up.
• Pump control coil fault.
• Brake valve/pump neutral bypass coil fault.
• There is only one steering control box present.
• The fault happens in the steering control box that has
control (Run/Stop switch in the RUN position).
• The fault occurs when neither steering control box is
in control.
