Object resolution
The device also contains a uniformly rotating mirror. The mirror deflects the light pulses
so that they extend over a 190° sector of a circle. This means an object in the protec‐
tive field can be detected within 190°. The first beam of a scan begins at −5° in rela‐
tion to the rear side of the safety laser scanner.
The device emits the light pulses with an angular resolution of 0.25 or 0.5° 1. This
enables resolutions between 30 mm and 150 mm to be achieved 2.
Thanks to the active scanning principle, the safety laser scanner does not need exter‐
nal receivers or reflectors. This has the following advantages:
•
The installation process requires very little time or effort.
•
The monitored area can be easily adapt to the hazardous area of the machine.
•
In contrast to tactile sensors, non-contact scanning is nearly wear-free.
Contour monitoring
In addit
ion to the protective field, the safety laser scanner can also monitor a contour
(e.g., the floor in vertical applications).
Mode of operation
The safety laser scanner can only fulfill its protective function if the following require‐
ments are satisfied:
•
It must be possible to influence the machine, system or vehicle control electrically.
•
It must be possible to change the dangerous state of the machine, the system or
the vehicle into a safe state at any time using the safety laser scanner. That is,
before the person reaches the hazardous points or hazardous areas.
•
The safety laser scanner must be arranged and configured in such a manner that
it can detect objects entering into the hazardous area.
•
The optical path of the safety laser scanner must be kept clear at all times and
must also not be obscured by transparent objects such as protective screens, plex‐
iglass, lenses, etc. The protective function of the safety laser scanner can only be
guaranteed if the contamination measurement function is not circumvented by
such measures.
