3 Safety
3.1 Intended use
The safety laser scanners of the PSEN sc B 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 hazardous areas within buildings,
}secure hazardous areas of vehicles and
}access protection 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 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
start.
}It must not be possible to operate the pushbutton for manual restart from inside the
hazardous area. The pushbutton must be located at a position from which there is a full,
unobstructed view of the hazardous area.
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 hazard-
ous area.
Their application must fulfil the site’s relevant national regulations (e.g.EN60204-1,

4 Function description
4.1 Basic function of the safety laser scanner
The safety laser scanner monitors an area that is covered by the light beam emitted by the
safety laser scanner.

[5]
Fig.: Operating principle safety laser scanner
Legend
[1] Hazardous area
[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 B 5 Series
1004508-EN-02 14
4.2 Use of zone sets and monitoring cases
A safety zone and a warning zone 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.
4.3 Automatic and monitored start/restart
Automatic start/restart
After switching on the safety laser scanner or re-release of the protected field, the safety
laser scanner automatically starts to the ON condition under these conditions:
}both OSSDs are wired correctly and
}no error has occurred and
}the safety zone is free.
If the safety zone is violated, the OSSDs switch to the OFF state.
Monitored start/restart function
The OSSDs switch to the ON state during operation under the following conditions:
}both OSSDs are wired correctly and
}no error has occurred and
}the protected field is clear 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 OSSD outputs are permanently checked by monitored test pulses. In the
case of detected errors at the OSSD outputs the safety laser scanner switches to the error
status.
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.

4.7 Stationary hazardous area
Using the safety laser scanner, you can monitor a stationary hazardous area, e.g. the envir-
onment of a machine that is installed in a fixed position.
The monitored area can be divided into subsections, for which monitoring can be activated
and deactivated each.

4.8 Multiple evaluation
When multiple evaluation is active, an object has to be scanned several times consecut-
ively before the safety laser scanner switches the OSSDs to the OFF state. This reduces
the probability that insects, welding sparks or other particles lead to a shutdown of a plant.
If a multiple evaluation of 4 is configured, an object has to be detected 4 times in succes-
sion in the safety zone, so that the safety laser scanner switches the OSSDs to the OFF
state.
With a multiple evaluation > 2 an allowance has to be made to the response time. The
height of the allowance (see Calculation of the overall response time [ 21]) results from
the value of the multiple evaluation and the valid response time (see Technical
details [ 66]).
4.9 Examples of application
If a violation of the safety zone is detected, the evaluation device switches off the outputs
configured for this. The machine is brought to a safe condition via the connected OSSDs.
If a violation of the warning zone is detected, the actions configured in PSENscanConfigur-
ator are performed. A visual or audible signal can be activated as advance warning.

1004508-EN-02 19
The minimum distance from the start of the protected area by the safety laser scanner to
the hazardous machine component should be such that the operator cannot reach the haz-
ardous area until the movement of the hazardous machine part has stopped.
In accordance with the standard
}ENISO13855
this distance depends on the following factors:
}Overall response time of the safety laser scanner
Time between the interruption of the laser beam and the OSSDs' change to the OFF
state (see Calculating the overall response time [ 21]).
}Machine's stopping time
Interval between the change of the OSSD to the OFF state and the stopping of the haz-
ardous machine movement (including the reaction time of the connected relay)
}Approach speed
The speed with which the object to be detected is nearing the hazardous area in mm/s
The following applies for PSEN sc B 5 Series:
S = K * (t1 + t2) + ZT + ZR + C
S Minimum distance in mm, measured from the start of the safety zone to the danger
source
K Approach speed with which the object to be detected is nearing the hazardous area
in mm/s (in accordance with ENISO13855)
K = 1600 mm/s for S > 500 mm
t1Overall response time of the safety laser scanner in seconds
Time it between the violation of a safety zone and signal change at the OSSD output
on the safety laser scanner
t2Machine's stopping time in seconds
