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
dangerous 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
indicates the minimum size that an object must be to allow it to be detected safely. The
scan cycle time also influences the response time.
The resolution in protective fields can be set to various values 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.

Table 2: Status LEDs
Number Function Color Meaning
1OFF state Red Lights up red when at least one
safety output is in the OFF state.
2ON state Green Lights up green when at least one
safety output is in the ON state.
3Warning field Yellow Shines yellow if at least one warning
field is interrupted.
4Restart interlock Yellow Setup with reset: Flashes if the
restart interlock has been triggered.
Configuration with automated restart
after a time: Lights up while the con‐
figured time to restart expires.
The OFF state and ON state LEDs 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
LEDs 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.
The device has different LEDs for every network interface. These network LEDs are
located below the display.
More information about the meaning of the LEDs see "Diagnostic LEDs", page 124.
Depending on the configuration, the display shows current information about the safety
laser scanner’s status, see "Buttons and display", page 114.
3.2.4 Connections
•1 x male connector, M12, A-coding for voltage supply
•2 × female connector, M12, D-coding for Ethernet (EtherNet/IP – CIP Safety, data
output, configuration, and diagnostics)
•1 × female connector, USB 2.0 Mini-B for configuration and diagnosis 1)
3.2.5 System plug
A system plug is required to operate the safety laser scanner.
The metal plate with the connections is the system plug (see figure 4, page 15). The
system plug can either be mounted on the rear side or the underside.
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
defective 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
•Warning field
1) The USB connection may only be used temporarily and only for configuration and diagnostics.

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
vehicle.
Figure 6: Protective field, shown in red in this document
Warning field
The warning field monitors larger areas than the protective field. Simple switching
functions can be triggered with the warning field, e.g. a warning light or an acoustic
signal can be triggered if a person approaches, even before the person enters the
protective field.
The warning field must not be used for safety applications.

3.2.7 Field set
A field set consists of one or more fields. The fields in a field set are monitored
simultaneously.
A field set can contain different field types, e.g., a protective field and a warning field.
A typical application is the use of a protective field with one or more warning fields: if a
vehicle approaches a person, a warning field triggers an optical or acoustic signal. If the
person does not react to this and the vehicle continues to approach, the safety laser
scanner detects an object in the protective field and switches the associated safety
outputs to the OFF state. The vehicle stops before it reaches the person.

yellow)

3.2.8 Monitoring case
A monitoring case signals the machine status to the safety laser scanner. The safety
laser scanner activates the field set, which is assigned to the monitoring case and
therefore a particular machine status.
If a machine, e.g., has various operational statuses, a monitoring case can be assigned
to each operational status. The safety laser scanner receives a defined signal for the
current operational status via the safety-related network. If there is a change of signal,
the safety laser scanner switches from one monitoring case to the monitoring case that
is assigned to the new signal (as well as the new operational status). Generally, one
field set is assigned to each monitoring case.
