Product description
3.3.1 Principles of operation
The S200 is an optical sensor that scans its surroundings in two dimensions using infrared
laser beams. It is used to monitor hazardous areas on machines or vehicles.
The S200 works on the principle of time of flight measurement. It sends out very short
pulses of light (S). At the same time an “electronic stopwatch” is started. When the light is
incident on an object, it is reflected and received by the safety laser scanner (E). From the
time between sending and reception (t) the S200 calculates the distance to the object.
In the S200 there is also a mirror rotating at constant speed that deflects the light pulses
such that they cover an arc of 270° .In this way an object can be detected in the
protective field within 270°. The first beam of a scan starts at S45° relative to the back
of the scanner.
The S200 sends a pulse of light with an angular resolution of 0.5°. In this way resolutions
from 30 to 70 mm can be achieved independent of the length of the protective field !

Product description
Due to its active scanning principle, the S200 does not require receivers or reflectors. This
has the following advantages:
Your installation effort is lower.
You can easily adapt the monitored area to the hazardous area on a machine.
In comparison with contact sensors, electro-sensitive scanning is nearly wear-free.
3.3.2 Field set comprising of protective field and warning field
The S200 protects the hazardous area on a machine or a vehicle using the protective
field .As soon as the safety laser scanner detects an object in the protective field, it
switches the OSSDs to the OFF state and thus initiates the shutdown of the machine or
stop of the vehicle.
You can define the warning field such that the safety laser scanner detects an object
before the actual hazardous area and e.g. triggers a warning signal.
The maximum distance at which the safety laser scanner can detect an object is defined
by the distance measuring range .
Protective field and warning field form a pair, the so-called field set.
With the aid of the CDS you can configure the field set and transfer it to the S200. If the
hazardous area to be monitored changes, then you can re-configure the S200 in software
without additional mounting effort.

3.4 Applications
3.4.1 Stationary applications
Hazardous area protection
On stationary machines, the S200 switches the output signal switching devices (OSSDs) to
the OFF state if the protective field is interrupted. The S200 initiates the shutdown of the
machine or the shutdown of the dangerous state.
Point-of-operation guarding
The S200 safety laser scanner can be used to prevent starting or restarting as long as
there are persons in the hazardous area. The machine can only be started or restarted if
the S200 does not detect any object in the protective field. This is particularly important
for system interiors that can only be seen with difficulty from the outside, or cannot be
seen at all.

Product description
In this application the S200 does not have a stop function. The primary protective
function that stops the dangerous movement is provided in the example by a light
curtain ,while the S200 monitors the restarting of the machine.
Hazardous point protection (vertical operation)
The S200 can used be used vertically to trigger stopping of the dangerous movement.
Compared to horizontal protection, the area to be protected in front of the machine or
system can be reduced. Hazardous point protection is necessary if the operator is near the
dangerous state of the machine. Hand protection is required to protect the hazardous
point.
Access protection (vertical operation)
You can also use the S200 vertically for access protection. Access protection can be used
when the access to the machine can be defined by physical means. In the case of access
protection, the S200 detects the entry of a person, but not presence in the hazardous area
(no point-of-operation protection).

Product description
3.4.2 Mobile applications
The S200 can be used both on manually controlled vehicles, e.g. fork lift trucks, and also
on automated guided vehicles (AGV) or trolleys.
You can use the S200 on vehicles, e.g. to protect the route of a vehicle through a factory
building. If there is a person or an obstacle in the hazardous area, the S200 ensures that
the vehicle reduces the velocity and stops if necessary.
The safety level of the S200 corresponds to category 2 according to EN 954-1. It is only
allowed to be used in corresponding applications.
3.5 Configurable functions
3.5.1 Field set
Configuration of the protective field and warning field
With the aid of the CDS you can configure the field set, which comprises a protective field
and a warning field. During this process you configure the shape and size of the protective
field and the warning field. You can realise any field shape required.
The area to be monitored is scanned radially by the S200. The S200 cannot see through
objects during this process. The area behind objects that are in the area to be monitored
(pillars, grilles, etc.) can thus not be monitored.
Protective field and warning field can cover up an angle of up to 270° and have different
radial scanning ranges depending on the resolution configured (see Tab. 3 on page 20).
Check the configured protective field!
Prior to commissioning the machine or vehicle, check the configuration of the protective
field using the instructions in chapter 8 “Commissioning” on page 50 and using the
checklist on page 77.
Protective field or warning field suggested by the safety laser scanner
The CDS can suggest the protective field or warning field. The safety laser scanner scans
the visible room contour several times. From the data obtained the CDS suggests the
contour and size of the field.
In those places at which the room contour is smaller than the maximum protective field
range (e.g. at ), the protective field corresponds to the room contour.

Product description
The measuring error tolerances for the S200 are automatically subtracted from the
protective field size. As a result the protective field is slightly smaller than the surface
covered .
In those places where the room contour is larger than the protective field range ,the
protective field corresponds to the possible scanning range (see Tab. 3 on page 20).
Check the protective field suggested!
The protective field suggested by the CDS is not a replacement for the calculation of the
safety distance. Calculate the safety distance based on the description in chapter 4
“Mounting” on page 27. Prior to commissioning the application, check the configuration of
the protective field using the instructions in chapter 8 “Commissioning” on page 50 and
using the checklist on page 77.
In the CDS field set editor, you can also request a suggestion for the protective field.
3.5.2 Application and resolution
With the aid of the CDS you can configure the S200 for use on a stationary or mobile
application. Also set the resolution of the S200.
The maximum protective field range depends on the resolution set. The following table
shows the related maximum protective field range at the resolutions that can be set:
Resolution Maximum protective field range
30 mm 1.25 m
40, 50, 70 mm 1.5 m
The maximum protective field range of the S200 must be sufficient to cover the
calculated protective field size including the necessary supplements (see section 4.1.1
“Protective field size” on page 28).
The warning field can be configured to up to 8 m for all resolutions. The detection
capability of the warning field is dependent on the remission of the objects to be
detected (see Fig. 41 “Diagram of scanning ranges for various reflectances” on
page 61).
