9.1 Working with the digital slope sensor
9.1.1 Installation and set-up
The digital slope sensor is mounted between the traction arms on the
crossbeam slightly downstream of the screed.
Four securing holes are provided for installation on the sensor's
mounting plate.
(Refer to the section entitled "Technical data" for an illustration of the
housing).
The plug connections must be freely accessible to enable the
connection cable to be connected easily. Please also note the paving
direction (FWD/arrow in direction of travel).
9.1.2 Actual value reset
Definition
On installation, the digital slope sensor should be mounted parallel to
the lower edge of the screed. As this is not always 100% possible in
practice, however, and an offset occasionally remains, the sensor is
then reset in the system.
After determining the "offset" between the measured value and reality,
the digital slope sensor then reflects the precise slope of the screed.
This is referred to as actual value reset.
Actual value reset must first be carried out on commissioning the digital
slope sensor.
For optimal working results, the actual value display must be checked
and, if necessary, corrected at regular intervals.
Actual value reset must generally be carried out again if …

the digital slope sensor has been replaced

the digital slope sensor's installation position has been changed

Mechanical changes have been carried out on the screed or its
mounting.
