LeeBoy 8515E - Auger and Screed System Control

4-24 LeeBoy 8515E Conveyor Paver
Operation
If equipped with the optional sonic auger sensor:
The augers can be controlled
automatically if the optional sonic
sensor system is installed and
active. The sonic auger sensor
detects the amount of material
present and controls its ow to the
end gates, gauging the amount of
paving material in the extensions.
(Figure 4-47) This option includes
an auger dial on each operator
control side for controlling material
height. The sonic auger sensors
are most often used when paving
widths exceeding nine (9) feet.
• Select AUTO or
MANUAL on the
screed control
box for desired
operational mode.
NOTE: The auger
switches
on the main
control panel
must be ON
to operate
the screed
control box or
auger dial.

Auger Sensor
The sonic auger sensor sits in the screed mount(s) on
either side, and connects to black plugs on the paver.
The black connectors are located in front of the levers
while the connector on the right side is located on the
frame near the spray down hose.
1. Plug in the sonic auger sensor to its connector on
the paver. (Figure 4-47)
2. Turn the auger switch ON and the corresponding
screed control auger switch to AUTO. (Figures
4-45 and 4-46)
3. Adjust material height using the auger dial (if
equipped). (Figure 4-35)
4. When the material moves into the sonic range,
the auger(s) will turn on and off automatically as
sensors detect material height.
