6.6 MUTING FUNCTION
This function can be enabled or deactivated by pin of RX connector (see section 5
The Muting sensors must be able to recognise the passing material (pallets, vehicles, ...) according to the
material’s length and speed. In case of different transport speeds in the Muting area, it is necessary to
consider their effect on the total Muting duration.
•
The Muting function, excludes the light curtain during functioning, maintaining active the
OSSD outputs, according to particular operating requirements (Figure 37).

•
The safety light curtain is equipped with two inputs (Muting1 and Muting2) for the activation
of this function, according to the Standards in force.
•
This function is particularly suitable when an object, but not a person, has to pass through
the dangerous area, under certain conditions.
•
It is important to remember that the Muting function represents a forced system condition
and therefore has to be use with the necessary precautions.
•
If Muting1 and Muting 2 inputs are activated by two Muting sensors or actuators, these
should be correctly connected and positioned in order to avoid undesired Muting or
potentially dangerous conditions for the operator.
•
State of Muting is signaled by Muting Lamp integrated on the top of receiver side (see
Figure 38). When the MUTING function in ON the LAMP becomes active. Contextually also
LAMP output line (PIN 10 M12-12 poles) is driven.
Figure 38
During the installation take care to place the lamps in an as visible as possible position.
If both the internal lamp and the external lamp are broken and/or not connected, the Muting
request causes the opening of the safety contacts, the device is blocked in SAFE state and the
failure is signaled (see par. 8.2).
