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.
See "When to disable" below.
To change the sensitivity level or disable the function, in the Inxpect Safety application click Settings and then 
Sensors.
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 Always restart 
prevention.
