Defining the echo selection
Depending on the measuring situation, the distance sensor receives echoes that can‐
not be assigned to the direct distance between the distance sensor and the measuring
object.
One possible cause for an echo like this is a viewing window in the measuring path
between the device and the measuring object.
The first echo (corresponds to the shorter distance between measuring object and
device) or the last echo (corresponds to the longer distance between measuring object
and device) from multiple detected echoes in the set distance and signal level area can
be selected for the signal evaluation.
Parameter
Factory setting
First echo:
For signal evaluation, the first echo is selected in the set distance
and signal level range.
First echo
Last echo:
For signal evaluation, the last echo is selected in the set distance
and signal level range.

Configuring the distance range
The distance range is the selectable, physical distance measurement range inside of
which measuring objects are evaluated and further processed.
Echoes from distances below or beyond this range are not included in the evaluation.
If no echo with a level within the signal level range is detected, the operating state “No
echo” is output. If a suitable lower measuring range limit is selected, disruptive optical
reflections of the front screen of a protective housing can be blanked, for example.
