DUST FILTERING
The Dust Filter Level must be set according to different conditions specific to the appli-
cation. In general, it is the sensibility to various l
evels of airborne particles that impact
the response of the Laser Sentinel detection.
A Low Dus
t Filter Level (default) is used in cleaner environments where airborne parti-
cles have little effect on object detection.
A High
Dust Filter Level is used in dirty environments to filter (ignore) detection of air-
borne particles from being confused with objects to detect. The Laser Sentinel is less
sensi
tive to dust and therefore avoids shutting down the machinery unnecessarily.
This parameter should be set to the lowes
t value that still allows the machinery to
work without detections due to dust.
NOTE
A Low Dust Filter Level could also prevent light interference and reflecting
background influences from reducing the device detection capability. Refer
to "
Light Interference" on page 12 and "High Reflecting Background" on
page 13
for more details.
