4.3 Sonic Sensors
The automatic material feed system uses sonic sensors
(1). Sonic sensing will allow you to maintain the amount
of material that you prefer on the end of the extension,
regardless of adverse paving conditions.
The sonic sensors are installed in holders on the screed
end gate. Before going any further make sure you have
followed one of the Automatic Material Feed Operation
setups.
Toggle display to feed control screen. Press material height
button to select low for material height below auger, medium
for material height level with auger, or high for material
height above auger.
If sonic sensor bracket has been inadvertently repositioned, sensor may pick up a reading from the auger
ighting, or from the back of the tractor. If this is occurring, remove sensor from bracket and try to identify what is
the obstruction. Direction of the bracket may need to be repositioned away from the obstruction.
