In a rest condition no safety or warning zones are monitored.
The safety laser scanner is still available for the operation and it can be switched back to
normal operation, if necessary.
4.14 Muting
The muting function can be used to suspend the safety function of the safety laser scanner
during operation, subject to special operating conditions.
} Example of a special operating condition:
Material is transported into the protective zone on a conveyor and the safety function is
overridden for the time it takes the material to pass through.
Muting is suitable when, under certain operating conditions, an object is permitted to pass
through the danger zone but a person is not.
CAUTION!
Risk of injury due to loss of the safety function
In muting status, the OSSDs continue to be in ON state. The connected ma-
chine remains in operation and represents a potential hazard.
– Prevent the possibility of access to the danger zone during muting.
Identification of the conveyed material (pallets, vehicles...) must be guaranteed with all
} Material dimensions and
} Conveyor speeds
that are intended to arise during operation.
} When the muting state of the safety laser scanner is detected, the safety laser scanner
triggers the configured actions for the muting state (e.g. switch on warning lamp or warn-
ing sound).
} Two muting areas can be created in a safety zone.
} Muting can be used in various versions.
– L muting: Only for removing material from the danger zone
– T muting: Transport of material in two directions
– Dynamic muting: Available for L muting and T muting
In addition to the conditions for L muting and T muting, activation and deactivation of
the muting state can be controlled by the connected safety controller.
