SAFERY LASER SCANNER
CHAPTER 2
TYPICAL APPLICATIONS
The safety laser scanner is used to detect people who are approaching a hazardous area
before reaching it, in order to prevent hazardous circumstances (e.g. a mechanical
movement) that may cause an accident.
The protective detection is done by defining a Safety Zone (the red zone in the figures),
whose shape and dimensions must be designed according to the risk assessment of the
machine. The user must consider the position of the hazardous point, the shape of the
machine and of the environment that surrounds it, and the time needed to stop the
dangerous movement.
To better ensure people’s safety, it is possible to define a Warning Zone (the yellow zone
in the figures): if a person or an object is approaching too close to the Safety Zone, the
safety laser scanner will trigger warning signals. This area cannot be used for safety pur-
poses.
The possible applications to employ the Laser Sentinel are: Horizontal (to monitor an
area that must be crossed in order to reach the hazardous point) and Vertical (to moni-
tor an access point).
