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.
