5.13 Rest condition
In a rest condition the functions of the safety laser scanner are deactivated to save energy.
This enables the use of the safety laser scanner with a supply voltage by battery (e.g. in an
automated guided vehicle system).
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.
5.14 Muting
Muting is the temporary, automatic suspension of a safety function. This suspension is
triggered via muting sensors, which are connected to the configurable inputs and detect an
object under defined conditions.
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 safety zone on a conveyor and the safety function is over-
ridden 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.

cycle
Explanation
Material has already passed the first muting sensor and is being
transported on the conveyor in the direction of the second mut-
ing sensor, muting lamp off.
Material on the conveyor passes the second muting sensor
(max.4s after the first sensor was passed). Muting lamp
flashes, signalling the muting status.
Material on the conveyor passes the PSEN sc M 3.0/5.5 08-17
series and the first muting sensor on the output side, muting
lamp flashes, signalling the muting status.
Material has left the area of the first muting sensor on the output
side, muting lamp is off, muting status is ended.
The next piece of material arrives at the first muting sensor.
