4. Functioning principles
4.9.4 Enable muting signal characteristics
The muting function is enabled only if both logic signals of the dedicated input meet certain characteristics.
Below is a graphic representation of the signal characteristics.
In the Inxpect Safety application, in Settings > Digital Input-Output it is necessary to set the parameters that
define the signal characteristics.
Note: with pulse duration = 0, it is sufficient that the input signals are at high logic level (1) to enable muting.
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 axes.
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.
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 unit at the following switch on.
