When to disable

The anti-masking function should be disabled under the following conditions:
(With restart prevention function) The monitored area includes moving parts that stop in different and
l
unpredictable positions.
The monitored area includes moving parts that vary their position while the sensors are in muting.
l
The sensor is positioned on a part that can be moved.
l
The presence of static objects is tolerated in the monitored area (e.g. loading/unloading area).

Description
The sensor has the highest sensitivity to
changes in the environment. (Suggested
level when the field of view is empty up to
the set masking distance)
The sensor has low sensitivity to changes
in the environment. Occlusion must be
evident (deliberate tampering).
The sensor detects masking only if the
sensor occlusion is complete and the
objects are highly reflective (e.g. metal,
water) near the sensor.
The sensor does not detect changes in
the environment.
WARNING
If the function is disabled the system
cannot signal the presence of objects that
might impede normal detection (see
Checks when the anti-masking function is
disabled below).
Schedule
Before each machinery restart
Each time the safety outputs are
deactivated
Example application
Installations with an empty environment
and a height of less than one meter, where
objects could occlude the sensor.
Installations with a height of more than one
meter, where masking is likely to occur
only if voluntary.
Installations on moving parts, where the
environment is changing continuously, but
where static objects may be near the
sensor (obstacles on the route).
See When to disable below.
Remove any objects that obstruct the field of
view of the sensor.
Reposition the sensor according to the initial
installation.
