Dust Filtration; Distance To Intense Light Sources And To Reflective Surfaces - Pilz PSEN sc M 3.0 08-12 Operating Manual

Project configuration

Dust filtration

The safety laser scanner has a dust filtration function. This changes the sensitivity of the
safety laser scanner, and the availability in dusty environments can be improved.
There are two levels:
}
Low for clean environments/low dust formation
} High for contaminated environments/strong dust formation
The default setting is low.

Distance to intense light sources and to reflective surfaces

Minimum distance to especially intense or flashing light sources
Pilz recommends that the safety laser scanner is not installed near particularly intense or
flashing light sources (e.g. flash units).
When especially intense or flashing light sources are near the safety laser scanner (area of
+/- 5° to the scanning plane, see figure), an allowance has to be considered when calculat-
ing the safety distance.

WARNING!
Loss of safety function due to a safety distance that is too low
Depending on the application, serious injury or death may result.
}
Depending on the degree of dust filtering, it is necessary to consider an
allowance for calculating the safety distance when installing the safety
laser scanner near intense light sources or reflective surfaces into ac-
count (see Distance to intense light sources and to reflective
surfaces [ 40]).
– When calculating the safety distance, ensure that the allowance is
considered depending on the dust filtering.
– Ensure that the new safety distance fulfils the specifications of the
safety assessment.
