The Safety Laser Scanner is an electro-sensitive device for the protection of operators against the risk of accidents caused by industrial machines and
plants with potentially dangerous moving parts and against possible collisions with Automatic Guided Vehicles (AGV).
For EN 61496-3, Laser Scanners must be certified in accordance to type 3 or lower (AOPDDR Active Optoelectronic Protective Device responsive to
For IEC 61508, IEC 62061, ISO 13849-1, they must be certified as SIL 2 - PLd or lower.
Using the Safety Laser Sensor, precise programmable horizontal protected areas of variable shape can be created (i. e. semi-circular, rectangular
or segmented), suitable for all applications with no need of a separate reflective or receiving element.
It is also possible to use the Laser Scanner in a vertical position for the access protection to a dangerous area, in that case detection of the edge of
the gate is mandatory (IEC TS 62046).
Any person or object entering or remaining in the safety zone during survey causes, through the self-monitored static safety outputs of the device, an
emergency stop command to the control system of the protected machine. The machine’s hazardous movement will thus be interrupted.
If the warning zone is instead occupied, thanks to a non-safety dedicated solid state output, a signal is sent to the machine control system, which can
be used to activate a light or a sound signal in order to prevent operators to break into the safety zone and stop the machine. Or, on an AGV application,
the warning signal can be used to slow the vehicle down, so that a possible further break of the safety zone will not force it to stop abruptly, thus
reducing the mechanical wear of the AGV.
The profiles of the controlled areas, as well as all the other configurable parameters, are programmable through a dedicated user interface software,
installed on a laptop or pc and connected with the scanner via a serial interface.
The Laser Scanner is also able to automatically detect the controlled area by means the teach-in function.
