Anti-Tampering Functions: Anti-Rotation Around Axes - Inxpect Value Line Instruction Manual

6.2 Anti-tampering functions: anti-rotation around axes
6.2.1 Anti-rotation around axes
The sensor detects rotation around its x-axis and z-axis.
Note: the axes are those represented in the figure below, regardless of the installation position of the sensor.
When the system configuration is saved, the sensor also saves its position. Later, if the sensor detects changes in
rotation around these axes, it sends a tamper alert to the control unit. Upon reception of a tampering signal, the
control unit deactivates the outputs.
Note: when the position is modified with respect to the saved references (i.e., when a sensor is rotated) and the
anti-rotation around axes function is enabled, the Inxpect Value Line detects the tampering and sends the
message within 5 s.
6.2.2 Enable the anti-rotation around axes function
The anti-rotation around axes function is disabled by default.
WARNING! If the function is disabled, the system cannot signal a change in the rotation of the
sensor around the x-axis and the z-axis and, therefore, cannot signal any changes in the monitored
area. See "Checks when the anti-rotation around axes function is disabled" below.
The function can be enabled and configured for each axis of each sensor individually. In the Inxpect Safety
application, in Settings > Anti-tampering, click on the specific option to enable the function for a sensor.
6.2.3 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.
6.2.4 Checks when the anti-rotation around axes function is disabled
When the anti-rotation around axes function is disabled, perform the following checks.
