The sonic auger controls
the amount of material
owing to the endgates,
gauging the amount of
paving material in the
extensions. (Figure
4-58) 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 4-58) It detects the material height and
controls the auger height by automatically turning the
auger on and off.
To operate the sonic auger sensor:
1. Plug in the sonic auger sensor unit.
2. Set the left and right auger switches on the left side
of the main control panel to AUTO. (Pages 3-6 to
3-9)
3. Set the left and right auger On/Off switch on the
screed control box to ON.
4. Adjust material height at the endgate using the
auger dial beside the steering control box. (Figure
4-59)
• 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.
