Description of Sensor Parameters
8.3.6
Upper Output Value
You can use this parameter to set the upper physical output value of the analog output, e.g., 20
mA with a 4..20 mA current output.

Sound Beam Width
Overview of Sound Beam Width
You can use the "Beam width" parameter to select one of the 3 predefined sound beam widths.
It is sometimes necessary to adapt the sound beam width, for example if in the application
objects can be detected in the boundary area of the sound beam, which can lead to incorrect
data.
Small beam width
This enables you to further adjust the width of this sound beam in a range of 10 ... 100 %
according to the previous selection of the small beam width (via parameter or programming
button).
Note!
The DTM will display just the appropriate upper output value depending on the set output type
for the analog output (current or voltage).

Note!
The selected sound beam width is a sensor adjustment and acts on all outputs alike. It is not
possible to assign an individual sound beam width to the individual outputs.

Note!
The 3 available sound beam widths are the same 3 which can also be selected via the
programming button on the sensor.
The following detailed settings for the selected sound beam widths are only an option in the
