8-10 LeeBoy Model 8510B Conveyor Paver
Troubleshooting
Steering/Acceleration And
Deceleration
Steering the paver is done by slowing the left or right
track. When a steering wheel with FNR joystick control
box is used the steering wheel angle at which counter-
rotation starts and the speed limit for counter-rotation
are pre-programmed into the Plus One’s memory. This
limits the ability to counter-rotate the tracks at high
speeds. If the FNR joystick is at 100% forward, as the
steering wheel was turned from centered to full right
the right track would only slow to 0% forward (at the
inection point) and never counter-rotate. If the FNR
joystick is at 50% forward the right track would counter-
rotate at 50% reverse (if the speed limit allows it to).
You can achieve full counter-rotation at either full left
or full right (hard-over) up to the speed limit, at which
point the counter-rotating track would decelerate to
zero speed (if over the speed limit). The counter-rotating
track can never exceed the speed of the forward track.
The steering wheel angle of inection (point at which the
controlled track would start to counter-rotate) and the
speed limit for allowing counter-rotation can be adjusted
with the Service Tool.
Each joystick and steering wheel has been setup with
individual prole and ramping to give smooth control.
Ramping for acceleration and deceleration is
proportional to the amount of movement of the joystick.
This will provide a quicker ramp for direction changes
and a slower ramp if the joysticks are moved to neutral.
These proles can be adjusted with the Service Tool.
The steering wheel prole has been setup to give a
ner degree of control when the wheel is moved a small
amount and more aggressive steering as the wheel is
turned more. These proles can be adjusted with the
Service Tool.
The steering wheel has a center position dead band
separate from the joysticks. This dead band is less than
that used by the joystick controller and reduces the
amount of “play” in the steering wheel. This dead band
can be set with the service tool.
Steering Box Control Selection
The Plus One will only assign control of the paver to
a steering control box if all joysticks are in NEUTRAL,
the steering wheels are centered and the RUN/STOP
switches are in the STOP position.
The Plus One will assign control to the rst box that is
switched to the RUN position.
If at anytime the RUN/STOP switch is set to the STOP
position the paver will decelerate to stop and set the
brake after 3 seconds. At anytime during operation if the
RUN/STOP switch on the second control box is set to
the RUN position the paver will decelerate to stop and
set the brake after 3 seconds.
Control will be restored to the operator when this switch
is set back to STOP (the paver will ramp back to the
setting of the operator’s controls). The purpose of this is
to allow personnel on the opposite side of the paver to
pause the paver and then return control to the operator
by ipping the RUN/STOP switch back to STOP.
Paver control can be switched to the second steering
control box by setting all joysticks in NEUTRAL,
centering the steering wheels, switching both RUN/
STOP switches to the STOP position and then switching
the second box to RUN.
Neutral Safety Lockout
This is an option built into the Plus One program. If at
anytime the paver is in NEUTRAL with the RUN/STOP
switch in the RUN position, the Plus One will disable the
control box after a set period of time. The operator will
be required to switch from RUN to STOP and back to
RUN to regain control. This is provided as a safety in the
event that the operator leaves his station with the control
box still active. When activated the paver will not if the
joysticks were accidentally moved without someone at
the controls. The length of time until lockout activates
can be adjusted with the Service Tool.
NOTE: The default is set at 30 Minutes.
