Contour detection field
T
he contour detection field monitors a contour of the environment. The safety laser
scanner switches the associated safety outputs to the OFF state if a contour does not
match the set parameters, because, for example, a door or flap is open.
The contour detection field is used for detecting changes in the environment and only
switches the outputs in the current monitoring case. By contrast, the reference contour
field is used for detecting changes at the safety laser scanner and switches all safety
outputs.
Warning field
T
he warning field monitors larger areas than the protective field. Simple switching
functions can be triggered with the warning field, e.g. a warning light or an acoustic
signal can be triggered if a person approaches, even before the person enters the
protective field.
The warning field must not be used for safety applications.

4.2.7 Field set
A field set consists of one or more fields. The fields in a field set are monitored
simult
aneously.
A field set can contain various types of field.
A typical application is the use of a protective field with one or more warning fields: if a
vehicle approaches a person, a warning field triggers an optical or acoustic signal. If the
person does not react to this and the vehicle continues to approach, the safety laser
scanner detects an object in the protective field and switches the associated safety
outputs to the OFF state. The vehicle stops before it reaches the person.
