3.3.4 Field types
During operation, the safety laser scanner uses its laser beams to continuously check
whe
ther people or objects are present in one or more areas. The areas to be checked
are called fields. A distinction is made between the following field types, depending on
the application type:
•
Protective field
•
Reference contour field
•
Contour detection field
•
Collision protection field
•
Warning field

Available only for devices with the Pro performance package and a maximum protective field range of
9 m.
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
vehicle.
