Reference contour field
T
he contour as reference field monitors a contour of the environment. The safety laser
scanner switches all safety outputs to the OFF state if a contour does not match the set
parameters, because, for example, the mounting of the safety laser scanner has been
changed.
National and international standards require or recommend that a reference contour is
monitored, if the safety laser scanner is used in vertical operation for hazardous point
protection or for access protection.
The reference contour field detects unintentional and intentional changes to the posi‐
tion or alignment of the safety laser scanner. Unintentional changes may be caused by
vibrations for example. An example of an intentional change is deliberate tampering to
disable the functionality of the safety laser scanner.
