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.
time of flight measurement
by the S200
t
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.
rotation of the S200
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 !
Due to its active scanning principle, the S200 does not require receivers or reflectors. This
as the following advantages:
h
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
warning field and distance
measuring range
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
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

system can be reduced. Hazardous point protection is necessary if the operator is near the

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).

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.
Note
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).

WARNING
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
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.

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:
field ranges at different
resolutions
Notes
ResolutionMaximum protective field range
30 mm1.25 m
40, 50, 70 mm1.5 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
In addition to the protective field, the S200 can also monitor a contour (e.g. the floor in
vertical applications or the walls in horizontal applications).

Note
For contour monitoring you define a contour segment . The contour segment comprises
a positive and a negative tolerance band.
The OSSDs on the S200 change to the OFF state if …
there is an object in the protective field.
the monitored surrounding contour is no longer in the tolerance band (e.g. if a door is
opened or if the position of the S200 is changed).
You can define any number of contour segments. The contour segments must not be
narrower than the configured resolution. At the points where a contour has been
configured as a reference you cannot define a warning field.
You define the contour as a reference in the CDS field set editor.
Vertical operation
In vertical operation (for access protection and hazardous point protection) according to
IEC/EN 61496<3 you must always configure the protective field with the contour as

Notes
3.5.4 External device monitoring (EDM)
After every interruption to the protective field and prior to restarting the machine, the
external device monitoring monitors the switching devices operated by the OSSDs (e.g.
contactors). In this way the external device monitoring detects whether, e.g. the (positively
guided) contacts on the contactors connected are in the OFF position.
The machine is only allowed to start if both contactors were in the OFF position before,
that is they were deactivated.
The table shows how the S200 reacts if the external device monitoring detects a contactor
malfunction:
Without internal restart

With restart interlock The S200 switches its OSSDs to the OFF state.
You can configure the external device monitoring in the CDS.
You will find examples on the connection of the external device monitoring in section 6.2
“Connection diagrams” on page 48.
If you do not use the external device monitoring function, leave the inputs disconnected
(see section 5.1.1 “Pin assignment on the system plug” on page 44).
The system locks completely (lock-out).

3.5.6 Restart
You can configure the restart behaviour of the S200 as follows:
without restart interlock
with restart delay
with restart interlock
It is imperative that you configure the S200 with restart interlock if the protective field
can be left to approach the hazardous point or if a person cannot be detected at every
point in the hazard area for the S200!
During the assessment, pay attention to whether the protective field can be left in the
direction of the hazardous point, to areas that are unprotected due to the mounting and
the unprotected near range of the S200 (see section 4.5 “Methods of preventing
unprotected areas” on page 36).
Configuration of the S200 without restart interlock
After the OSSDs on the S200 have been switched to the OFF state due to an object in the
protective field, the OSSDs are re-enabled again immediately when there is no longer an
object in the active protective field.
This configuration is only allowed …
if an external restart interlock is realised on the machine controller
or
if the protective field cannot be left in the direction of the hazardous point and if people
can be detected by the S200 at every point in the hazardous area!
Restart delay for mobile applications
In mobile applications you can configure a restart delay from 2 to 60 seconds on the
S200. The OSSDs on the S200 change to the ON state if there is no object in the
protective field for the duration given.
This configuration is only allowed if the protective field cannot be left in the direction of the
hazardous point and if a person can be detected by the S200 at every point in thehazardous area!
The OSSDs on the S200 change to the OFF state to trigger a machine or vehicle stop as
soon as there is an object in the protective field . They do not change to the ON state ,
even if there is no longer an object in the protective field. The OSSDs only change to the
ON state if the operator operates the control switch for restart or reset.
Place the control switch for restart or reset in a suitable place!
Place the control switch for restart or reset outside the hazardous area such that it cannot
be operated by a person in the hazardous area. Ensure that the person who operates the
control switch has a full view of the hazardous area.
Reset
The reset function is often also called “preparation for restart”. In these operating
instructions the term reset is used.
If you want to activate the restart interlock on the S200 (internal) and also a restart
interlock on the machine (external), then each restart interlock has its own control switch.
After operating the control switch for the internal restart interlock (with protective field
unoccupied) …
the S200 switches its OSSDs to the ON state.
the LED
The external restart interlock prevents the machine from restarting. After resetting the
S200 the operator must press the control switch to restart the machine controller.
The controller must be realised such that the machine only restarts if the S200 is first
reset and then the control switch for restarting the machine controller is operated.
You will find examples on the connection of the internal restart interlock in chapter 6.2
“Connection diagrams” on page 48.
If you do not use the internal restart interlock, leave the inputs disconnected (see
section 5.1.1 “Pin assignment on the system plug” on page 44).
You can configure the type of restart in the CDS.

3.5.7 Multiple sampling
If multiple sampling is set, an object must be scanned several times before the S200
switches its OSSDs to the OFF state. In this way you can reduce the probability that
welding sparks, insects or other particles, result in the shutdown of the plant.
If a multiple sampling of 3 is configured, for instance, an object must be detected three
times in succession before the S200 switches the OSSDs to the OFF state.
he total response time is increased by the multiple sampling!
T
With a multiple sampling greater than 2, note that you must add a supplement to the basic
response time (see section 11.2 “OSSD response times” on page 61)!
On the S200, a multiple sampling of 2 is the minimum setting. You can set the multiple
sampling to up to 16 with the aid of the CDS.

3.5.8 Stand-by mode
If, in mobile applications, vehicles are not moved for a time, the OSSDs and the laser on
the S200 can be switched off. In this way the power consumption of the device is reduced.
Use this function if, e.g. you use several vehicles and do not move them for a time.
A dedicated STBY single-channel input is provided for switching to the stand-by mode (see
section 5.1.1 “Pin assignment on the system plug” on page 44).
3.5.9 Naming applications and laser scanners
A name can be assigned to the application configured and to the laser scanner(s). The
names are saved in the devices after the configuration is transferred. The name chosen
may be, for example, the identifier for the vehicle, system or the machine.
You enter the application name and the name of the laser scanner used in the CDS.
The outputs are fed out at the system plug (see section 5.1 “System connection” on
page 43).
All outputs are only allowed to be used for the purpose specified. Note that the signals at
the application diagnostics outputs for “warning field”, “contamination of the optics
cover/error” and “reset required” are single-channel and therefore are not allowed to be
used for tasks related to safety. For this reason the warning field is not allowed to be used
