Enable The Anti-Rotation Around Axes Function; When To Enable; Checks When The Anti-Rotation Around Axes Function Is Disabled - Leuze electronic LBK SBV Original Operating Instructions

5 Functioning principles
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 deactivates the safety outputs.
The sensor can detect changes in rotation around the x-axis and the z-axis even if it is switched off. The
tamper alert is sent to the controller at the following switch on.
A change in rotation around the y-axis is detected only if it is faster than 5° every 10 s and if the system is
on.
The tamper alert due to a rotation around the y-axis is reset at the next switch on. For proper
and safe operation of the system, validate the system again.
5.10.2

Enable the anti-rotation around axes function

The anti-rotation around axes function is disabled by default.
If the function is disabled, the system cannot signal a change in the rotation of the sensor
around the axes and therefore any changes in the monitored area. See Checks when the
anti-rotation around axes function is disabled below.
Take precautions to prevent tampering, if the function is disabled for at least one axis of one
sensor and if the rotation around that axis is not protected with tamper-proof screws.
The function can be enabled and configured for each axis of each sensor individually. In the LBK Designer
application, in Settings > Anti-tampering, click on the specific option to enable the function for a sensor.
5.10.3

When to enable

Enable the anti-rotation around axes function only if it is necessary to detect a change in the rotation of a
sensor around a specific axis.
It is strongly suggested not to enable the function if the sensor is installed on a moving object (e.g. carriage,
vehicle) whose motion could change the sensor inclination (e.g. motion on a slope or in a curve).
