3 Product description
3.1 Setup and function
The safety laser scanner is an electro-sensitive protective device (ESPE), which two-
dimensionally scans its environment with infrared laser beams.
The safety laser scanner forms a protective field using the invisible laser beams. This
protective field protects the hazardous area and enables hazardous point protection,
access protection or hazardous area protection. As soon as an object is situated in the
protective field, the safety laser scanner signals the detection by means of a signal
change at the safety output (OSSD for example). The machine or its control must safely
analyze the signals (for example using a safe control or safety relays) and stop the dan‐
gerous state.
The safety laser scanner operates on the principle of time-of-flight measurement. It
emits light pulses in regular, very short intervals. If the light strikes an object, it is
reflected. The safety laser scanner receives the reflected light. The safety laser scanner
calculates the distance to the object based on the time interval between the moment of
transmission and moment of receipt (∆t).

Figure 3: Light pulses scan an area
1Angular resolution: the angular distance (in degrees) between 2 distance measurements
Scan cycle time and resolution
The time that the mirror requires for one rotation is called the scan cycle time. The
number of light pulses per unit of time is constant. The scan cycle time and the number
of light pulses per unit of time determine the angular resolution. The scanning range for
a given object resolution depends on the angular resolution. The object resolution indi‐
cates the minimum size that an object must be to allow it to be detected safely. The
scan cycle time also influences the response time.
Slightly different scan cycle times can be used to minimize mutual interference in
neighboring safety laser scanners.
The resolution in protective fields can be set between 30 mm and 200 mm, according
to the intended purpose.
Geometry of the scan plane
The laser beams emitted cover a sector of a circle, so an object can be detected in an
area of up to 275°.
The sector of a circle covered ranges from –47.5° to 227.5°, where 90° denotes the
axis of the safety laser scanner from the back to the front. When viewing the safety
laser scanner from above, the direction of rotation of the mirror and the deflected light
pulses is counterclockwise, see figure 3.

The safety laser scanner can be mounted and operated in any alignment. In this docu‐
ment, position and direction information is used as follows with respect to the safety
laser scanner, as long as different usage is not indicated separately:
•The top is the side of the safety laser scanner on which the optics cover is located.
•The bottom is the side of the safety laser scanner opposite the optics cover.
•The front is the side of the safety laser scanner on which the display is located.
The 90° angle of the sector of a circle scanned by the safety laser scanner points
in this direction.
•The back is the side of the safety laser scanner opposite the display. The sector of
a circle not scanned by the safety laser scanner lies in this direction.

The OFF state and ON state light emitting diodes can be found in multiple locations on
the safety laser scanner. 3 additional sets are arranged in pairs on the base of the
optics cover. So the light emitting diodes can also be seen in many cases when it is not
possible to see the display, e.g. due to the mounting situation or because it is hidden
from the operator’s position.
More information about the meaning of the light emitting diodes see "Diagnostic LEDs",
page 118.
Depending on the configuration, the display shows current information about the safety
laser scanner’s status, see "Buttons and display", page 107.

OSSD
An OSSD is a safety switching output. The functionality of each OSSD is tested periodi‐
cally. OSSDs are always connected in pairs and must undergo dual-channel analysis for
safety reasons. An OSSD pair is formed from 2 OSSDs that are connected and analyzed
together.
3.2.5 System plug
A system plug is required to operate the safety laser scanner.
The base plate is the system plug (see figure 4, page 14).
The safety laser scanner’s internal configuration memory is integrated in the system
plug. The system plug and all connecting cables can remain at the installation site
when the safety laser scanner is replaced. The system plug is detached from the defec‐
tive safety laser scanner and connected to the new safety laser scanner. The new
safety laser scanner reads the configuration from the configuration memory when
switching on.
3.2.6 Field types
During operation, the safety laser scanner uses its laser beams continuously to check
whether people or objects are present in one or more areas. The areas to be checked
are called fields. A distinction is made between the following field types, depending on
how the safety laser scanner is used:
•Protective field
•Reference contour field
•Contour detection field

Tamper protection e.g. door monitoring
Protective field
The protective field protects the hazardous area of a machine or vehicle. As soon as the
electro-sensitive protective device detects an object in the protective field, it switches
the associated safety outputs to the OFF state. This signal can be passed to controllers
resulting in the dangerous state coming to an end, e.g. to stop the machine or the vehi‐
cle.
Figure 6: Protective field, shown in red in this document
Reference contour field
The reference contour field monitors a contour of the environment. The safety laser
scanner switches all safety outputs to the OFF state if a contour does not match the set
parameters, because, for example, the mounting situation of the safety laser scanner
were changed.
National and international standards require or recommend that a reference contour is
monitored, if the safety laser scanner is used in vertical operation for hazardous point
protection or for access protection.
The reference contour field detects unintentional and intentional changes to the posi‐
tion or alignment of the safety laser scanner. Unintentional changes may be caused by
vibrations for example. An example of an intentional change is deliberate tampering to
disable the safety laser scanner’s functionality.

Contour detection field
The contour detection field monitors a contour of the environment. The safety laser
scanner switches the associated safety outputs to the OFF state if a contour does not
match the set parameters, because, for example, a door or flap is open.
The contour detection field is used for detecting changes in the environment and only
switches the outputs in the current monitoring case. By contrast, the reference contour
field is used for detecting changes at the safety laser scanner and switches all safety
outputs.
3.2.7 Field set
A field set consists of one or more fields. The fields in a field set are monitored simulta‐
neously.
A field set can contain various types of field.
3.3 Example applications
Hazardous area protection
In hazardous area protection, people are detected if they stay in a defined area.
This type of protective device is suitable for machines, where it is possible to see a haz‐
ardous area completely from the reset pushbutton. When the hazardous area is
entered, a stop signal is triggered and starting is prevented.

area
Hazardous point protection
In hazardous point protection, the approach is detected very close to the hazardous
point.
The advantage of this type of protective device is that it is possible to have a short mini‐
mum distance and the operator can work more ergonomically.

Access protection
In access protection, people are detected if their whole body passes through the protec‐
tive field.

This type of protective device is used for the protection of access to hazardous areas.
When the hazardous area is entered, a stop signal is triggered. A person standing
behind the protective device will not be detected by the ESPE.

Mobile hazardous area protection
Mobile hazardous area protection is suitable for AGVs (automated guided vehicles),
cranes and forklifts, to protect people when vehicles are moving or docking at a fixed
station.
The safety laser scanner monitors the area in the direction of travel and stops the vehi‐
cle as soon as an object is located in the protective field.
