5 FUNCTIONING PRINCIPLES
The detection distance of one or more fields can be 0 (e.g. protective field 3). The first
protective field with a detection distance other than 0 (e.g. protective field 1) must have
a minimum detection distance of 500 mm.
5.2.5
Protective fields dependency and detection signal generation
If a sensor detects motion within a protective field, its detection signal changes status
and, when configured, the related safety output is deactivated. The behavior of the
outputs related to the following protective fields depends on the protective field
dependency set:
If...
Then...
the
Dependent mode
is set and thus protective
fields are dependent on each other
if a sensor detects motion within a protective
field, all the outputs related to the following
protective fields are also deactivated.
Example
Protective field configured: 1, 2, 3
Protective field with target detected: 2
Protective field in alarm status: 2, 3
the
Independent mode
is set and thus
protective fields are independent from each
other
if a sensor detects motion within a protective
field, only the output related to that protective
field is deactivated.
Example
Protective field configured: 1, 2, 3
Protective field with target detected: 2
Protective field in alarm status: 2
WARNING
If protective 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 protective fields.
