4-26 LeeBoy 8515D Conveyor Paver
Operation
To operate the sonic auger sensor
1. Set the left and right auger switches on the left side
of the control panel to AUTO. (Pages 3-6 to 3-9)
2. Set the left and right auger switches on the right
side of the control panel to the SLAVE position.
3. Set the left and right auger On/Off switch on the
remote control box to ON. (Figure 4-44)
4. Adjust material height at the endgate using the
auger dial beside the steering 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 speed will slow down
proportionately and turn off. It will turn back on
when the material level drops.

Sonic Auger Sensor
The sonic auger controls the amount of material flowing
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 not used in the manual mode. (Figure
4-47)
A sonic auger sensor connects from the paver to the
screed. It detects the material height and controls the
auger height by automatically turning the auger on and
off.
The sonic auger sensors are most often used when
paving widths of nine to 15 feet (2.7 - 4.6 meters).
NOTE: The augers are not needed when paving under
eight-feet wide (2.4 m).
