3 Safety
3.1 Intended use
The safety laser scanners of the PSEN sc L 3/5 series are electrosensitive protective equip-
ment of ESPE type 3. They are used to protect personnel and systems. The safety laser
scanners are designed to
}secure danger zones within buildings,
}secure danger zones of vehicles and
}protect the access within buildings.
The safety laser scanner may only be used for personal protection on machinery if
}the hazardous state can be removed by the safety laser scanner and
}the starting of the machine is controlled by the safety laser scanner and
}the safety assessment prescribes no better detection capability than 40 mm, 70 mm.
The safety level PL d (Cat. 3)/SIL CL 2 is only achieved if
}The safety outputs must be processed safety-related in 2-channel mode.
The restart of the machine or vehicle can be performed using a manual or an automatic re-
start.
}It must not be possible to operate the pushbutton for manual restart from inside the
danger zone. The pushbutton must be located at a position from which there is a full, un-
obstructed view of the danger zone.
Prevent circumvention of the safety zone. This means that other electrosensitive protective
equipment and protective measures may be required in addition to the safety laser scanner.
These should be determined via a safety assessment based on the specific application
range and specific local conditions (e.g. official specifications).
Refer to IEC/TS 62046 to determine other necessary safeguards for securing the danger
zone.
Their application must fulfil the site’s relevant national regulations (e.g.EN60204-1,

Legend
[1] Danger zone
[2] Area covered by the laser beam
[3] Safety laser scanner
[4] Safety zone
[5] Warning zone
The area can be divided into a safety zone and a warning zone.
If an object or a person enters the warning zone, corresponding actions can be triggered
(e.g. switch on indicator light unit).
If an object or a person violates the safety zone, the OSSDs switch to an OFF state.

Function description
Operating Manual PSENscL 3/5 series
1005056-EN-01 | 15
4.2 Use of zone sets and monitoring cases
A safety zone and one or two warning zone(s) constitute a zone set.
A monitoring case is a defined signal at the control inputs for the current machine state. For
one specific machine state, one specific monitoring case can be assigned.
The safety laser scanner uses the defined signal at the control inputs to activate the zone
set, which is assigned to this monitoring case and therefore to a specific machine state.
When a machine has e.g. different operating statuses, a safety laser scanner can be used
to monitor several operating statuses.
When using two zone sets, the monitoring of zone set 1 can be switched to the monitoring
of zone set 2. The switching is controlled by the configurable inputs.
The standard behaviour when switching the monitoring cases does not plan an overlap of
the zone sets.
}Max. number of zone sets
– PSEN sc L with use of 8-pin connection: 3
– PSEN sc L with use of 12-pin connection: 10
}Max. number of inputs for switching zone sets
– PSEN sc L with use of 8-pin connection: 3
– PSEN sc L with use of 12-pin connection: 5
4.3 Automatic and monitored start/restart
Automatic start/restart
After switching on the safety laser scanner or re-release of the safety zone, the safety laser
scanner automatically starts, and the OSSDs switch to the ON state under these condi-
tions:
}Both OSSDs are wired correctly and
}No fault has occurred and
}the safety zone is free.
If the safety zone is violated, the OSSDs switch to the OFF state.
Monitored manual start/restart
The OSSDs switch to the ON state during operation under the following conditions:
}Both OSSDs are wired correctly and
}No fault has occurred and
}The safety zone is free and
}at least 80 ms have elapsed since switching to the OFF state and
}The start button has been operated and then released again for a min. 0.5 s and a max. 5
s. The start occurs with a falling edge.

4.5 OSSD
The switched on OSSDs are permanently checked by monitored test pulses. In the case of
detected errors at the OSSDs, the safety laser scanner switches to the error status.

Function description
Operating Manual PSENscL 3/5 series
1005056-EN-01 | 17
4.6 Reset
The Reset function can be used to set the safety laser scanner back to normal operation,
when the safety laser scanner has changed to an error state because of a non-critical error.
The reset pushbutton has to be connected to the reset input.
To trigger a reset, the reset pushbutton has to be pressed for at least 500 ms.
OSSD
Fig.: Timing diagram reset
4.7 EDM
Contactors outside the safety laser scanner can be monitored (External Device Monitoring
= EDM, also known as feedback loop monitoring).
EDM only needs to be activated if the contactors are controlled directly.
A test is performed to see that the N/C contacts switch if the state of the OSSDs changes
and so is used to monitor and detect malfunctions on the contactors. If a malfunction is de-
tected, the safety laser scanner switches to a safe condition and stops the connected ma-
chine. This check is carried out each time the OSSDs are triggered and before restarting.
The EDM function is available:
}Only when using the 12-pin connection
}Only for the OSSD pairs 1 and 2.

The function is activated or deactivated with the Wiring [ 45].
4.8 Wave
With the wave function, a safety laser scanner that is to be configured in a network can be
identified more easily from its position.
When starting the automatic search for a safety laser scanner in a network the wave button
can be selected.
The device found registers with the flashing message in the display.
4.9 Muting
The muting function can be used to suspend 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 laser scan-
ner is overridden for the time it takes the material to pass through.
Muting proves to be particularly suitable when, under certain operating conditions, an object
is permitted to pass through the danger zone but a person is not.

Function description
Operating Manual PSENscL 3/5 series
1005056-EN-01 | 19
Identification of the conveyed material (pallets, vehicles...) must be guaranteed with all
}Material dimensions and
}Conveyor speeds
that are intended to arise during operation.
The muting sensors are connected to muting inputs 1 and 2. The muting sensors must be
positioned and installed at a right angle to the safety laser scanner (see Installation and
wiring [ 53]).
}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).
}Muting can be used in various versions.
– L muting: Transport of material in one direction
– 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.

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 access to the danger zone during muting.
}The muting state is shown by the muting lamp and in the display of PSEN sc L 3/5 series.
The muting lamp must be connected to the PSEN sc L 3/5 series and positioned so that
the muting lamp is clearly visible form the whole danger zone.
}Use a muting lamp with an LED lamp and a max. current consumption of 250mA.
}If the muting lamp is defective, the muting function cannot be activated. Any attempt to
activate the function will immediately trigger the PSEN sc L 3/5 series and instantly switch
off the OSSDs; the muting lamp fault indicator will also light.
4.10 Override
With the override function, a machine can be restarted even though the safety zone is viol-
ated by material.
The aim is to clear the danger zone of any material that may have accumulated due to a
fault in the operating cycle.
If there is a pallet in the safety zone, for example, and the conveyor can no longer be
switched on because the safety laser scanner is keeping the OSSDs switched off (because
the safety zone is not free), the accumulated material cannot be transported away from the
zone.
Activating the override function allows intervention and enables the conveyor to be restar-
ted.
The safety laser scanner has two connections for override, which are connected via N/O
contacts at 24VDC (Override1) and 0VDC (Override2). Both contacts are closed if the
override function is activated.
Automatic ending of override function
The override function is ended automatically when one of the following conditions is met:
}Muting timeout has elapsed
}The conditions necessary for activation are no longer present.
}Max. duration of override function has elapsed: After 120s, the safety laser scanner
switches back to its normal operating status.
}No muting sensor is active
}Safety zone is not violated
