12.32.2 Defining a protection zone
It is also possible to define protection zones in two dimensions.
Two-dimensional protection zones that must be monitored mutually, must be defined in the
same plane.
In the event of an error, alarm 111 ”Error in collision monitoring data” is output with the code
96=protection zones not defined in the same plane.
In the 3rd coordinate, the dimension of two-dimensional protection zones is assumed to be +/-
infinite.

12.32.3 Activation of collision monitoring of a protection zone
Collision monitoring is activated for each individual protection zone in machine data 3876*
”Protection zone exists”.
Because of the specific machine geometry, it might be necessary to model the geometric
space that a machine part requiring protection occupies more precisely than is possible with a
single protection zone.
To achieve a better approximation of the protection zone to the geometry of the machine part,
it is possible to define several protection zones that describe the machine part section by
section.
Because mutual monitoring of these spaces is not necessary, it can be deactivated for each
protection zone in machine data 3880*-38921* ”No monitoring with reference to SR”. It is
necessary to deactivate monitoring in the machine data of both protection zones.
In the event of an error alarm 111 ”Error in collision monitoring data” is output with code
03=Error in monitoring reference.
