5.1 Select installation location
Observe the following instructions for the selection of the installation location:
►
The object
③
must be in the field of view
④
�
> The size of the field of view is indicated in the data sheet� The size of the
field of view depends on the distance of the device to the object
⑤:
With
increasing distance the field of view becomes larger�
►
Avoid direct reflections from the floor�
►
Take tolerances into account when positioning the object�
►
When determining the distance between device and object
⑤
take the measuring
range of the device into account�
> The measuring range is indicated in the data sheet of the sensor�
►
Select a distance as small as possible between device and object
⑤
�
> If the distance is as small as possible, the object is detected with the maximum
resolution�
►
Avoid any strong ambient light and sunlight at the installation location�
> An extraneous light level of over 8 klx (with solar spectrum) causes
measurement errors� In fact, only the infrared component between 800 and 900
nm is of concern�
►
Avoid transparent panes between the device
①
and the object
③.
> Transparent panes reflect part of the light even if a very clean glass pane is used�
If the instructions are not observed, measurement errors may occur�
