Protective field
T
he protective field protects the hazardous area of a machine or vehicle. As soon as the
electro-sensitive protective device detects an object in the protective field, it switches
the associated safety outputs to the OFF state. This signal can be passed to controllers
resulting in the dangerous state coming to an end, e.g. to stop the machine or the vehi‐
cle.

Reference contour field
T
he reference contour 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 situation of the safety laser scanner
were 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.
