4.7.5 Sensitivity level
The anti-masking function has 4 levels of sensitivity:
Level Description Example application
High The system has the highest sensitivity to changes in
the environment.
Installations with a static environment and
a height of less than one meter, where
objects could occlude the sensor.
Medium The system has low sensitivity to changes in the
environment. Occlusion must be evident (deliberate
tampering).
Installations with a height of more than
one meter, where masking is likely to occur
only if voluntary.
Low The system detects masking only if the sensor
occlusion is complete and the objects are highly
reflective (e.g. metal, water) near the sensor.
Installations on moving parts, where the
environment is changing continuously, but
where static objects may be near the
sensor (obstacles on the route).
Disabled The system 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 with anti-masking function
disabled" below.
See "When to disable" below.
To change the sensitivity level or disable the function, in the Inxpect Safety application, in Settings then click
Sensors.
4.7.6 Checks with anti-masking function disabled

Safety function Schedule Action
Access detection
function
Before each machinery restart Remove any objects that obstruct the field of
vision of the sensor.
Reposition the sensor according to the initial
installation.
Restart prevention
function
Each time the safety relays are
de-energized
4.7.7 When to disable
The anti-mask function hast to be disabled under the following conditions:
l (with restart prevention function) the monitored area includes moving parts that stop in different and
unpredictable positions,
l 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).
