4.9.5 Muting status

Any output dedicated to the muting status (Muting enable feedback signal) is activated if at least one of the

groups of sensors is in muting.

NOTICE: it is the responsibility of the machinery manufacturer to assess whether the indication of the muting

status is necessary (as defined in section 5.2.5 of EN ISO 13849-1:2015 standard).

4.10 Anti-tampering functions:anti-rotation around axes

4.10.1 Anti-rotation around axes

The sensor detects rotation around its x-axis and z-axis.

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 unit. Upon reception of a tampering

signal, the control unit deactivates the safety outputs.

4.10.2 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 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.

In the Inxpect Safety application, in Settings click Sensors to disable the anti-rotation around axes function.

4.10.3 Checks when the anti-rotation around axes function is disabled

When the anti-rotation around axes 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 same as defined

by the configuration.

See "Validate the safety functions" on page68.

Each time the safety outputs are

deactivated

4.10.4 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).
