4-28 LeeBoy 8510E Conveyor Paver
Operation
Sonic Auger
The sonic auger controls the amount of material owing
to the endgates, gauging the amount of paving material
in the extensions. An operator can operate the sonic
auger from either side of the paver. The sonic auger
sensors are most often used when paving widths of
nine to 15 feet (2.7 - 4.6 meters) and are not used in the
manual mode.
The sonic auger sensor sits in the screed mount and
connects to the plug under the screed auger dial box.
(Figure 4-47) It detects the material height and controls
the auger height by automatically turning the auger on
and off.
NOTE: The augers are not needed when paving under
eight-feet wide (2.4 m).To operate the sonic
auger sensor:
Figure 4-47. Sonic Auger Sensor Option
To operate the sonic auger sensor:
1. Plug in the sonic auger sensor unit (bottom of the
Material Height Dial).
2. Pull the auger lever down.
3. Set the left and right auger switches on the left side
of the control panel to AUTO.
4. Adjust material height at the endgate using the
auger dial beside the steering control box (or
remote screed control box). (Figure 4-48)
• The right and left auger dials controls material
height. Turning the dial clockwise increases
material height while turning counterclockwise
decreases material height.
• When the material height moves into the sonic
range, the auger will automatically turn off. It will
turn back on when the material level drops.
