Machine Sensor Calibrations
Calibrating machine components ensures accurate, consistent, and
efficient paving. Operators or technicians perform calibrations in the
following instances:
• Upon initial installation of machine components.
• After servicing the system, performing maintenance, or replacing
a component.
• When the machine no longer paves the correct cross-slope.
• After installing a PZS-MC sensor antenna on the machine.
Calibrating the Sensors Using the
Slope Control Key
Sensor calibration calibrates the slope control system of the
machine’s screed. The sensor attached to the machine also needs to be
calibrated. The sensor is attached to moving parts that wear at
different rates. In order for the system to work correctly, it has to be
“told” what changes have occurred on the machine. The control box
saves calibration settings in its memory until the operator or
technician changes them.
Pavers require only one sensor to control cross slope. This sensor
must be calibrated to accurately measure the slope of the screed.
1. At the control box, press the
Slope Control Key
.
2. Place a precision carpenter’s level along the bottom of the screed.
Then manually tilt the screed until it is level.
3. Once the screed is dead level, press the Blade slope
Set
key to
adjust the slope (Figure 5-10 on page 5-16).
4. Enter 0.0 and press
OK
. The Blade slope value displays as 0.0%
on the
Adjust Slope
dialog box (Figure 5-10 on page 5-16).
