4.2.5 Detection fields dependency and detection signal generation
If a sensor detects motion within a detection field, its detection signal changes status and, when configured, the
related safety output is deactivated. The behavior of the outputs related to the following detection fields depends
on the detection field dependency set:
If... Then...
the Dependent mode is set and thus detection fields
are dependent on each other
if a sensor detects motion within a detection field, all
the outputs related to the following detection fields are
deactivated too.
Example
Detection field configured: 1, 2, 3
Detection field with target detected: 2
Detection field in alarm status:2, 3
the Independent mode is set and thus detection fields
are independent from each other
if a sensor detects motion within a detection field, only
the output related to that detection field is
deactivated.
Example
Detection field configured: 1, 2, 3
Detection field with target detected: 2
Detection field in alarm status:2
WARNING! If detection fields are independent, an evaluation of the safety of the monitored area
must be performed during the risk assessment. The blind area generated by a target can prevent the
sensor from detecting targets in the following detection fields.
In this example, both detection field 1 and 2 generate a detection signal, for target [A] and [B] respectively.
