Figure 6: Reference contour field, shown in blue-green in this document
The contour detection field monitors a contour of the environment. The electro-sensitive
protective device switches the associated safety outputs to the OFF state if a contour
does not correspond to the set specifications, e.g. because 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.
3.3.5
A field set consists of one or more fields. The fields in a field set are monitored
simultaneously.
A field set can contain various types of fields.

Example applications
Hazardous area protection
In hazardous area protection, people are detected if they stay in a defined area.
This type of protective device is suitable for machines, where it is possible to see a
hazardous area completely from the reset pushbutton. When the hazardous area is
entered, a stop signal is triggered and starting is prevented.
