2System Overview
2.1Brief Description and Functional Principle of the SIMATIC FS600 Laser
Scanner
The SIMATIC FS600 Laser Scanner is an optical distance sensor that takes twodimensional measurements. It could also be referred to as an optical area radar device.
The sensor uses a rotating deflecting unit to periodically emit light pulses within a
working range of 190°.
If these pulses strike a person or an obstacle, the reflected light is received and
evaluated by the SIMATIC FS600 Laser Scanner. The scanner calculates the precise
coordinates of the person or object based on the travel time of the reflected light and the
current angle of the deflecting unit. If the person or obstacle is within the bounds of a
previously defined area called a detection zone, a safety-oriented switching function is
performed. This switching function causes the semiconductor outputs to be switched off.
The safety-oriented switching function cannot be reset until the detection zone is clear.
Depending on the operating mode, the reset can be initiated either automatically or
manually.

A laser diode coupled with transmitter optics produces focused light pulses. These
pulses are projected across the monitored surface by a rotating mirror in such a way that
a light pulse is triggered in each of the angle segments within 40 ms (scanning rate: 25
scans/s).

Fig. 2.1-2:Functional principle of the SIMATIC FS600 Laser Scanner
The SIMATIC FS600 Laser Scanner can detect people up to a distance of 4.0 m e.g.
2.15 m – even if they are wearing very dark clothing or exhibit a low degree of
reflectance. Dangerous movements are brought to a standstill by two failsafe
semiconductor outputs.
Objects (min. 150 x 150 mm) are detected up to a distance of 15 m (corresponds to
the warning zone) and signaled by way of a non-safety-related semiconductor output.
Four programmable zone pairs (each of which consists of one detection zone and one
warning zone) enable the scanner to be optimally adapted to the needs of each
particular application.
The SIMATIC FS600 Laser Scanner can be implemented not only on machines and
systems (stationary safeguarding of danger zones), but also on vehicles (mobile
safeguarding of transport vehicles).
Due to its wide range of measurement and its non-contact, electro-sensitive
measurement principle,
the SIMATIC FS600 Laser Scanner can be effectively used as a protective device for
virtually any application.
2.2Special Features of the SIMATIC FS600 Laser Scanner

3Safety notes and usage in accordance with intended purpose
3.1General safety notes
SIEMENS products are developed and manufactured with careful application of
standard rules of the industry. The protective function of the devices can be negatively
affected, however, if they are used improperly or not in accordance with their intended
purposes. If this occurs, it may not be possibly to safeguard danger areas completely
or at all, which may result in danger to life and limb for persons who are in the general
area of the machines or systems.
CAUTION – LASER RADIATION!
The SIMATIC FS600 Laser Scanner is a laser device belonging to laser class 1. The
valid legal and local regulations for operating laser systems must be complied with.
Avoid positioning the scanner at eye level.
3.2Usage requirements and usage in accordance with intended purpose
The relevant regulations for machine safety apply for the use of the SIMATIC FS600
Laser Scanner. Responsible authorities (for example professional trade unions, OSHA)
are also available for questions related to safety. In general, the following usage
requirements must be observed:
•If the scanner is enclosed in a protective housing, additional window material, such
as plastic or glass must not be used as it may impair the detection.
•Avoid touching the scanner optical window and the six diffusing light screens.
•The SIMATIC FS600 Laser Scanner is not suitable for use as a protective device:
-if it is possible that dangerous fluids will be spewed out or objects will be
-ejected. for machines with long braking times (max. depth of the detection
zone: 4 m)
For these cases, SIEMENS offers suitable safety interlocking devices (safety
switches) with and without guard locking.
•The SIMATIC FS600 Laser Scanner corresponds to Type 3 in accordance with
IEC 61496-1 and –3A safety category of 3 in accordance with EN 954-can be
achieved with the SIMATIC FS600 Laser Scanner if all other elements in the safety
chain are set up to stop the dangerous motion in accordance with that safety
category.
•The electrical connection of the SIMATIC FS600 Laser Scanner to the control
system must only be made by an electrician.
•The 24-V DC power supply (+20 %, -30 %) must be ensured by a safe network
disconnect in accordance with IEC 742. The same requirements apply to all
connected input and output circuits..
17
•The 24-V DC power supply must be fed to the scanner through a separate branch
with a 1.25 Amp delayed action fuse in the control cabinet.
•Guard operation is only permitted with the control cable (X1) of the dummy
connector . This also applies for transport and storage.
•The safety output has a double design. The two OSSDs must always be included
in the shut-off circuit of the machine in such a manner that either of the two is
completely sufficient by itself to turn off the motion that presents a danger.
•The alarm output 1 (Pin 5 on X1) must not be used to switch safety-related signals.
•System tests (of the scanner, machine, control components and switch
components) may only be performed when they do not result in potential hazards
for people.
•Tampering with or making changes to the SIMATIC FS600 Laser Scanner can
result in the loss of the safety function.
•Only expert trained personnel is allowed to perform startup, maintenance,
parameter settings or detection zone configurations. Familiarity with the safety
notes in this Connecting and Operating Instruction and in the operating instructions
for the “SIMATIC FS600 Parameterization Software LS4soft” program constitutes
part of this expert knowledge.
•The password required for configuring safety-relevant parameters must be kept in
a secure location by the safety official. Information about password levels can be
found in the “SIMATIC FS600 Parameterization Software LS4soft” user's manual.
•If the machine is designed for start interlock /manual restart, all detection zones
must be checked before enable - no one is permitted in the danger area.
3.3Restrictions for Use
•Glass, highly reflective materials such as mirrors (reflectance > 10,000 %), or
objects that do not reflect any light back to the sensor can falsify the measurement
result. More information is available in Chapter 5.3.5.
•Do not expose the SIMATIC FS600 Laser Scanner to flying sparks (for example a
welding flash). Doing so may cause damage to the optical window.
•Vapor, smoke, dust and all particles visible in the air have a significant negative
effect on measurement values and will result in the semiconductor outputs being
turned off.
•Avoid extreme variations in temperature.
18
•Make sure that the following types of light sources are not present on the scanning
plane:
-Laser light from one or more other scanners or sensors
-Infrared light
-Fluorescent light
-Stroboscopic light
Please consider as well Chapter 5.2.
•It must not be used with internal combustion engines.
•The SIMATIC FS600 Laser Scanner is conceived for use inside enclosed spaces
and with the operating parameters listed in the technical specifications
(temperature, humidity, shock, vibration, etc.). Please refer to the list of parameters
in Chapter 14.
•Avoid having reflective surfaces (such as glass, mirrors, retro-reflectors, etc.) at
fixed contours in the scanning plane. If this is not possible, an additional detection
zone must be provided.
3.4Information Related to Detection Zone Changeover
If alternating operation is included in the design, and thus detection zone changeover,
the activation and effect of the detection zone in question must match the alternating
operating mode.
•The new detection zone must be activated before turning off the previous detection
zone. The time at which the changeover is made must be based on a risk analysis.
•Braking paths, response and coast-down times must be taken into consideration
(for example overlapping detection zones).
•A “Start interlock” function is provided.
•If the machine has a restart key, it must not be possible to operate it from inside the
detection zones. All danger areas must be visible from the position of the button.
Before releasing the start/restart interlock, all detection zones must be tested. No
one is permitted inside the danger areas.
•There must be no unmonitored zones inside the danger areas.
•There must be no possibility for direct access to the danger area that shortens the
necessary safety distance (use a protective grid, for example).
•The information on required detection zone additions in Chapter 5 must be
observed.
19
3.5General information related to determining detection zone contours
•Shadow effects (e.g. surfaces or areas located behind stationary objects) must be
considered. As a rule, insufficient safeguarding must be adequately supplemented
by further safety measures such as guard fences, light curtains, and the like!
•Access to the detection zone in the dangerous area is not permitted.
•When setting the dimensions of the detection zone, you must comply with the
formulas cited in Chapters 5.4.8 and 5.7.9 ! Be sure to comply with higher-level
machine standards (e.g. DIN EN 1525) if applicable.
These contain individual specifications, for example, on points of access to the
danger zone and, if applicable, detection zone additions that must be given special
consideration.
They also provide information on how to measure safety distances at machines.
•Detection zones with a radius smaller than 20 cm (at or close to the scanner) are
not admissible. 20 cm is the preset minimum contour.
•When setting the dimensions of the detection zones, please comply with the
maximum angle error stated in the technical specifications (Chapter 14.11).
•Needle-shaped detection zone contours are not permitted, since they do not
ensure any protective effect. For additional information, please refer to the
SIMATIC FS600 Parameterization Software LS4soft user software (Chapter
entitled “Definition of Detection Zones”).
•Due to possible measurement errors, every detection zone has an additions area
in which detection is not guaranteed under all conditions. Please consider as well
Chapter 5.3.5. Read Chapter 5.4.6 and 5.7.7 for information on optimizing system
availability.
•The required safety distances must be taken into account when making detection
zone configurations. Safety distances are calculated according to formulas found in
either the machine-specific C standards or the general B standards IEC 61496-3 in
combination with DIN EN 999 (see Section 2 and 5 of the standard). Tolerance
fields and/or additions
(make sure to consider Chapter 5.4 and 5.7).
•After the detection zones have been set, make a printout of the following
information:
-Detection zone contour with the X and Y coordinates
-Date
-Serial number of the scanner
-Name of the safety official
•When calculating the additions, be sure to consider whether the dust algorithm is
deactivated or activated (see Chapter 5.3.5).
20
•When calculating the safety distances, be sure to consider all delay times, such as
the response time of the scanner, response time of the control elements, and
braking times and/or stopping times of the machine/system or AGV! Variations in
delay time caused by factors such as reduced braking power must also be taken
into consideration.
•The effectiveness of the switch-off function must be tested along the defined
contour of the detection zone during the initial startup and subsequent to any
changes made to a machine or system.
•The effectiveness of the switch-off function must be tested for the detection zone
contours along the entire driving route during the initial startup and following any
changes made to an AGV.
•In the event that there is insufficient room available to allow the full dimensions of
a detection zone, for example because of the position of the scanner, additional
safety measures (e.g. safety grids) must be installed.
•Following each definition of and change to the detection zones, the configuration
must be checked to see whether the possibility of people standing in the danger
zone as well as any barriers provided have been considered by an appropriate
layout of the detection zone(s).
3.6Additional Safety Notes for Stationary Use
•If the danger zone can be accessed from the side, and if the detection zone cannot
be extended sufficiently in this direction, additional safety measures (e.g. safety
fences) must be installed.
•We recommended marking the contour of the detection zone on the floor by
painting a colored line or applying colored adhesive tape.
•Check the mounting regularly (in particular, the angle of inclination) in order to
guarantee the reliability of detection.
21
3.7Additional Safety Notes for Mobile Use
•There are additional requirements for the use of scanners on automatic guided
vehicles (AGV) and transporter trolleys according to DIN EN 1525.
•If possible, expanded detection zones to each side should be provided in order to
safeguard access from the side and directly in front of the vehicle.
•If is it not possible to completely safeguard the contour of the vehicle including its
trailer and the dimensions of its load while making curves, additional protective
devices such as switch strips must be attached to the side of the vehicle.
•There must be a minimum safety distance S
on both sides. A one-sided minimum safety distance is admissible in certain
exceptional cases. The specifications of DIN EN 1525 must be complied with.
•The basic value of the detection zone width for an AGV corresponds to the
maximum vehicle width including the trailer and the dimensions of the load plus the
detection zone additions Z
AGV while making curves must be considered when defining detection zones.
•If the SIMATIC FS600 Laser Scanner is mounted on vehicles, the mounting
(especially the angle of inclination), the vehicles' braking power, and if applicable,
play in the vehicle guidance (the difference between the optimum and actual line of
guidance) must be regularly checked in order to guarantee the reliability of
detection.

4Applications for the SIMATIC FS600 Laser Scanner
Due to its continuous coverage of the area, its wide range, and the ability to select
among four / eight zone pairs, the SIMATIC FS600 Laser Scanner is able to handle even
complex applications
4.1Stationary Safeguarding of the Danger Area
The SIMATIC FS600 Laser Scanner is used to safeguard dangerous working areas at
machines and systems where both constant and variable demands are placed on the
geometrical shape of the detection zone. The aim is to prevent people from entering the
danger zone or reaching the danger point with their upper and/or lower extremities, at
the same time without impeding the production process.
The SIMATIC FS600 Laser Scanner can be mounted directly at the machine table or
on the side or in front of the machine.

4.2Access guarding by passage monitoring
Access guarding by passage monitoring (whole body trip control) is a suitable method
when the access to a machine or to a hazardous zone can be precisely defined in
structural terms, and there is no other unprotected access to the area. It is best to mount
the laser scanner above the passage in question, in vertical alignment. In order to secure
the protective equipment, laser scanner and fence against inadvertent misadjustment
and manipulation, the detection zones of the SIMATIC FS660I Laser Scanner must be
defined on the basis of a reference boundary. In this operating mode, the scanner will
use the polled environment as a reference and so check for changes in the layout of the
protective equipment, as well as checking every one of the individual measurements it
carries out with a view to detecting an intrusion. An example of the configuration of the
SIMATIC FS660I Laser Scanner to give access protection by passage monitoring will be
found in Chapter 5.5.

4.3Safeguarding of danger points based on hand and arm detection
If the machine operator, in close proximity to the danger zone, needs to halt the
hazardous movement of the machine or to coordinate the handling of workpieces or their
removal from the machine, the machine must be provided with protection at the danger
point. To safeguard danger points in this way a protective system needs to be installed.
The SIMATIC FS660I Laser Scanner is certified as a system providing hand and arm
protection, and is able in such a situation to guarantee flexible safety conditions in the
workplace. This may be combined with alternation of the detection zones. In order to
safeguard the protective equipment, laser scanner and side-mounted panels (which
serve as a reference and provide additional access protection) against inadvertent
misadjustment or manipulation, the detection zones of the SIMATIC FS660I Laser
Scanner must be defined on the basis of a reference boundary.
An example of the configuration of the SIMATIC FS660I Laser Scanner for the protection
of danger points based on hand and arm protection may be found in Chapter 5.6.

4.4Mobile Safeguarding of Automatic Guided Vehicles
For this application, the SIMATIC FS600 Laser Scanner is installed on automatic guided
vehicles in order to monitor the vehicle path. The aim is to detect people or objects in the
path of the vehicle and to automatically bring the vehicle to a halt. Safety systems
available up to now, such as bumpers or safety bars, have allowed only very low driving
speeds to be maintained. In contrast, using the SIMATIC FS600 Laser Scanner as a
non-contact “advance bumper” results in the creation of a substantially larger safety
zone.
The vehicles can move faster, and down times are reduced to the necessary minimum.

4.5Protecting Transporter Trolleys against Collisions
Transporter trolleys are generally guided along a system of rails or grooves in the floor.
Hence the vehicle paths are usually just slightly wider than the trolleys themselves. This
represents an increased hazard for people, since it is impossible to get out of the way of
the trolley. For this reason, transporter trolley are used in enclosed areas equipped with
suitable access safeguarding.

Please comply with the safety notes in Chapter 3 and Chapter 5.7.8.
In these cases, the SIMATIC FS600 Laser Scanner is used to detect people or objects
in the vehicle path and then automatically bring the vehicle to a halt. Select “Manual
restart” mode.
The demands placed on the geometrical shape of the detection zone are determined by
the vehicle width, speed, stopping distance and response time. Here as well, factors
such as additions in the direction of travel for tolerances in the measurement value and
reduced braking power due to wear and tear must be taken into consideration.
4.6Guarding the sides on AGVs
In addition to the danger area guarding of the path of an AGV application, in some cases
it is also necessary to set up a side guarding. This side guarding detects people in the
space between vehicle and conveyor, or detects people that stand on the conveyor edge
in the vehicle area. Furthermore, the side guarding also enables the correct position of
the load to be monitored, so that a transport with overhanging load is not initiated.
27

5Information for Planning and Mounting
It is essential that the following key points be complied with so that the SIMATIC FS600
Laser Scanner can provide optimum performance:
•The SIMATIC FS600 Laser Scanner must be placed so that areas of access to the
danger zone being monitored are completely covered by the detection zone.
•The mounting position of the scanner should provide protection from humidity, dirt
and extreme temperatures below 0° C or over 50° C.
•The mounting position must be selected in such a way as to minimize the possibility
of mechanical damage. Additional protective cover panels or safety bars must be
installed at exposed positions.
•Reinforcements, cover panels, mounting niches, and other machine elements may
not in any way impair the field of view of the scanner.
•If there are areas of shadow caused by fixed obstacles that were defined as part of
the detection zone boundary, these should be safeguarded (e.g. by safety grids) in
order to prevent people standing in them from being able to suddenly enter the
detection zone. This point must be taken into account in the hazard analysis of the
machine or system.
•Be sure that there are no retro-reflectors or highly reflective surfaces made of metal
or ceramic in the area of the detection zone and at the height of the scanning plane.
Such objects can cause measurement errors.
•In order to ensure a consistent detection height at every point of the detection zone,
the scanner – and hence the scanning plane – must be placed parallel to reference
section.
•If the “Restart interlock” function is included, the restart button must ne located
outsidethe detection zone in a place that is visible from the entire danger area .
•If the scanner is used without a start interlock or startup test with automatic start/
restart, a startup warning (visual or acoustic) must be provided.
•The scanner must not be used as an aid for climbing. If there is is any risk, a
suitable diagonal protection (45°) should be set up.
Please comply with the safety notes in Chapter 3, Chapter 5.4.7 and 5.7.8.

5.1Attachment and Dimensions
For attaching the SIMATIC FS600 Laser Scanner, four drill holes are located at the back
of the unit. Any laser scanner installation point is possible with mounting. The SIMATIC
FS600 Laser Scanner can, for example, also be mounted on the head or inclined facing
down.
The mounting set 3RG7838-1AA is available as an accessory offering following
advantages:
•Speeds up the mounting process by providing screws that are accessible from the
front.
•Allows vertical inclinations of up to 9°, either up or down, infinitely adjustable within
this range.
•Allows lateral tilting of up to approx. 9° to either side from the midpoint setting,
infinitely adjustable within this range.
•Enables quick replacement of the scanner without requiring realignment.
For information on which parts and dimensions are required for mounting, please refer
to Chapter 14.13 and 14.14.
5.2Installing adjacent laser scanners
The SIMATIC FS600 Laser Scanner has been developed in a way that prevents several
laser scanners from interfering with one other as much as possible.
WARNING
An increase in the response time can, however, be caused by the installation of several
adjacent laser scanners. If
in the following sections or the specific adjustment (section 5.2.2) are implemented,
then the SIMATIC FS600 Laser Scanner response time set and shown in the
configuration and diagnosis software (SIMATIC FS600 Parameterization
Software LS4soft) is extended by 40 ms.

5.2.1 Constructive measures
The direct external light irradiation from laser scanners of the same kind (905 nm laser
light wavelength) in a line and at the same installation height can be prevented with
shielding plates at scan level. Shielding, as high as the scanner front screen and flush
with the front housing edge, is sufficient. The same also applies with installation in
vertical alignment and overlapping of the scan levels
