6.1 Muting
6.1.1 Description
The muting function is an additional safety-related function that inhibits the sensing capability of the sensor on
which it is activated. It can be activated for a specific sensor or for a group of sensors. This results in keeping the
ON-state of the OSSD or the safety Fieldbus even when the muted sensors detect motion.
When the muting function is enabled, its effective activation on one or more sensors occurs only as soon as the
conditions permit (see "Muting" above).
6.1.2 Muting enabling
The muting function can be enabled through digital input (see "Enable muting signal characteristics" on the next
page) or safety Fieldbus (if available).
WARNING! If the muting function has been enabled through the safety Fieldbus and the digital
inputs, only the digital inputs enabling is considered for the function.
WARNING! When the sensor is in muting, no sensor error is available (see" ERRORevents (sensor)"
on page97).
Through the safety Fieldbus (if available) the muting function can be enabled for each sensor individually.
Through digital inputs the muting function can be enabled for all the sensors simultaneously or only for a group of
sensors. Up to two groups can be configured, each associated with a digital input.
Through the Inxpect Safety application, the following must be defined:
l
for each input, the group of managed sensors
l
for each group, the sensors that belong to it
l
for each sensor, whether it belongs to a group or not
Note: if the muting function is enabled for one sensor, it is enabled for all the detection fields of the sensor,
regardless if the detection fields are dependent or independent and the anti-tampering functions are disabled for
that sensor.
See "Configure the inputs and outputs" on page76.
6.1.3 Muting activation conditions
The muting function is activated on a specific sensor only in the following conditions:
l
All the detection fields involved have no active detection signal, no active static object detection signal, and
the restart timeout has expired for all of them.
l
There is no tampering signal or fault signal for that sensor.
When the muting is enabled for a group of sensors, the function is activated for each sensor as soon as there is no
detection in its monitored area, regardless of the status of the other sensors.
WARNING! Enable the muting signal on sensors monitoring the same dangerous area once the whole
area is safe and nobody can access it. If the muting is enabled when some of the sensors are still
detecting a movement, a person could move to a space monitored by a muted sensor, compromising
the safety of the whole area.
