Level
Description
Example application
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 when the anti-masking
function is disabled" below.
To change the sensitivity level or disable the function, in the Inxpect Safety application click

4.11.6 Checks when the anti-masking function is disabled
When the anti-masking function is disabled, perform the following checks.
Safety function
Schedule
Action
Access detection
function
Before each machinery restart
Remove any objects that obstruct the field of view
of the sensor.
Reposition the sensor according to the initial
installation.
Restart prevention
function
Each time the safety outputs are
deactivated
4.11.7 When to disable
The anti-masking function should 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).
4.12 Multi-control unit Synchronization
4.12.1 Introduction
The multi-control unit synchronization function is necessary when multiple LBK System Series are sharing the
same area and it allows the interferences between their sensors to be removed using a time synchronization
signal.
Note
: the function can be used only if all the sensors have the safety working mode set to
