3.1 Setup and function
The safety laser scanner is an electro-sensitive protective device (ESPE), which two-
dimensionall
y scans its environment with infrared laser beams.
The safety laser scanner forms a protective field using the invisible laser beams. This
protective field protects the hazardous area and enables hazardous point protection,
access protection or hazardous area protection. As soon as an object is situated in the
protective field, the safety laser scanner signals the detection by means of a signal
change at the safety output (OSSD for example). The machine or its control must safely
analyze the signals (for example using a safe control or safety relays) and stop the dan‐
gerous state.
The safety laser scanner operates on the principle of time-of-flight measurement. It
emits light pulses in regular, very short intervals. If the light strikes an object, it is
reflected. The safety laser scanner receives the reflected light. The safety laser scanner
calculates the distance to the object based on the time interval between the moment of
transmission and moment of receipt (∆t).
