6. Other functions
To change the sensitivity level or disable the function, in the Inxpect Safety application, click Settings > Anti-
tampering and search for Anti-masking sensitivity.
To set the distance, in the Inxpect Safety application, click Settings > Anti-tampering and search for Anti-
masking distance.
6.3.6 Checks when the anti-masking function is disabled
When the anti-masking function is disabled, perform the following checks.
Safety function Schedule Action
Access detection
function
Before each machinery restart Remove any objects that obstruct the field of view
of the sensor.
Reposition the sensor according to the initial
installation.
Restart prevention
function
Each time the safety outputs are
deactivated
6.3.7 When to disable
The anti-masking function should be disabled under the following conditions:
l
(With restart prevention function) The monitored area includes moving parts that stop in different and
unpredictable positions.
l
The monitored area includes moving parts that vary their position while the sensors are in muting.
l
The sensor is positioned on a part that can be moved.
l
The presence of static objects is tolerated in the monitored area (e.g., loading/unloading area).
6.4 Auto-resume (5.x sensors only)
6.4.1 Introduction
Some transient faults cause a permanent lock-out condition that prevents normal operation from being restored.
While the safe state is maintained, this behavior represents a limitation, especially for remote systems that are
not easily accessible.
The Auto-resume function tries to restore the normal functioning of the sensor for five consecutive attempts: if
the fault condition persists, the block condition is preserved. Otherwise, the normal functioning condition is
automatically restored.
6.4.2 Function limitations
The following faults are not subjected to auto-resume:
l
POWERERROR
l
SIGNALERROR
l
TAMPERERROR
l
TEMPERATUREERROR
The function is not performed when the sensor is muted.
6.5 Electromagnetic Robustness
6.5.1 Electromagnetic robustness parameter
With the Electromagnetic robustness parameter, it is possible to increase the robustness of the system to
electromagnetic interference (e.g., due to sensors of different systems installed too close to each other or
problems on the CAN bus).
In the Inxpect Safety application in Settings > Advanced, the following levels of robustness can be set:
l
Standard (default)
l
High
l
Very High
WARNING! The parameter impacts the system response time for the access detection safety
function. According to the chosen level, the maximum guaranteed response time is 100 ms
(Standard), 150 ms (High), or 200 ms (Very High).
