Subject to change without notice
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 control. Upon reception of a tampering signal, the control 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 control at the following switch on.
Note
: a change in rotation around the y-axis cannot be detected if the movement occurs
while the system is turned off.
5.10.2
Disable the anti-rotation around axes function
WARNING
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
when the anti-rotation around axes function is disabled below
).
WARNING
Take precautions to prevent tampering, if the function is disabled for one axis and if the
rotation around that axis is not protected with tamper-proof screws.
The function can be disabled for each axis individually. In the safeRS3 Designer
application, in
Settings
click
Sensors
to disable the anti-rotation around axes function.

5.10.4
When to disable
It may be necessary to disable the anti-rotation around axes function if the sensor is
installed on a moving object (e.g. carriage, vehicle) whose motion would change the
sensor inclination (e.g. motion on a slope or in a curve).
