Inxpect LBK System User Manual

When the system configuration is saved, the sensor also saves its position. If the sensor subsequently
detects changes in rotation around these axes, it sends a tamper alert to the controller. Upon reception of a
tampering signal, the controller de-energizes the safety outputs.
4.6.2 Disabling the anti-tampering function
WARNING! If the function is disabled, the system cannot signal a change in the rotation of the
sensor around the longitudinal and transverse axes and therefore any changes in the monitored
area. See "Checks with anti-tampering function disabled" below.
In the application Inxpect Safety in Settings click Sensors to disable the anti-tampering function.
4.6.3 Checks with anti-tampering function disabled
When the anti-tampering function is disabled, perform the following checks.
Safety function Schedule Action
Access detection
function
Before each machinery restart Check that the sensor position is that defined by
the configuration.
Check that the monitored area is the one defined by
the configuration.

4.6.4 When to disable
It may be necessary to disable the anti-tampering function if the sensor is installed on a moving object (e.g.
carriage, vehicle) whose movement would change the sensor’s inclination (e.g. movement on a slope).
4.7 Anti-masking function
4.7.1 Masking signal
The sensor detects the presence of objects that could obstruct the field of vision. When the system
configuration is saved, the sensor memorizes the surrounding environment in a one meter radius. If the
sensor subsequently detects variations in the environment that could influence the field of vision, it sends a
masking signal to the controller. Upon reception of a masking signal, the controller de-energizes the safety
outputs.
4.7.2 Environment memorization process
The sensor starts the surrounding environment memorization process when the Inxpect Safety application
configuration is saved. From that moment, it waits for the system to exit the alarm status and then scans
and memorizes the environment for 15 seconds.
It is recommended to start the memorization process after at least 3 minutes from turning on the system to
guarantee that the sensor has reached the working temperature.
Only at the conclusion of the memorization process it is possible for the sensor to send masking signals.
4.7.3 Causes of masking
Possible causes of masking signals are presented as follows:
l an object has been placed inside of the stopping area that obstructs the field of vision of the sensor.
l the environment in the stopping area changes significantly, for example, if the sensor is installed on
moving parts or if there are moving parts inside of the stopping area.
l the configuration has been saved with sensors installed in an environment that is different from the
working environment.
4.7.4 Masking signal when the system is turned on
If the system was off for several hours and there were temperature fluctuations, the sensor might send a
false masking signal when it is turned on. The signal deactivates automatically within 3 minutes when the
sensor reaches its working temperature.
