2 GENERAL INFORMATION ABOUT THE PRODUCT
2.1 GENERAL DESCRIPTION OF THE SAFETY LIGHT CURTAINS
The safety light curtains of the SG BODY series are optoelectronic multibeam devices that are
used to protect working areas that, in presence of machines, robots, and automatic systems in
general, can become dangerous for operators that can get in touch, even accidentally, with moving
parts.
The light curtains of the SG BODY series are safety systems used as accident-prevention
protection devices and are manufactured in accordance with the international Standards in force
for safety, in particular:
EN 61496-1:2013 Safety of machinery: electrosensitive protective equipment.
Part 1: General prescriptions and tests.
EN 61496-2:2013 Safety of machinery: electrosensitive protective equipment - Particular
requirements for equipment using active optoelectronic protective
devices.
EN ISO 13849-1:2008 Safety of machinery. Safety-related parts of control systems.

The device, consisting in one active unit inside a sturdy aluminum profile and a passive unit
composed of two or more deviating mirrors, generates couples of infrared beams able to detect an
opaque object positioned within the light curtain detection field.
The active unit is composed of two types of optic groups: emitting and receiving units.
The infrared beam, generated by an emitting optic group, is reflected by the deviating mirrors and
thus re-guided towards the corresponding receiving optic group of the active unit.
The passive unit is composed of a sturdy aluminum profile containing pre-assembled and pre-
aligned mirrors.
The solution with integrated Muting arms can be implemented both in a ‘T’ or ‘L’ configuration.
The active unit is equipped with the command and control functions. The connections are made
through a M12 connector located in the lower side of the profile of the active unit.
The microprocessor guarantees the check and the management of the beams that are sent and
received through the units: The microprocessor LEDs and display inform the operator about the
general conditions of the safety light curtain (see section 8 ”DIAGNOSTICS”).
The device consists in 2 units: the active unit and the passive unit. The active unit, according to the
model, is composed by one or several emitting and receiving modules and checks the control
operations and safety actions.
During installation, a user interface facilitates the alignment of both units (see section 7 –
“ALIGNMENT PROCEDURE”).

As soon as an object or the operator’s body accidentally interrupts one or some of the infrared
beams sent by the emitter, the receiver immediately opens the OSSD outputs and blocks the
MPCE machine (if correctly connected to the OSSD).

•Shorter response time (see section 11 –“TECHNICAL DATA”)
•Muting function customization
•Override function customization
2.4 HOW TO CHOOSE THE DEVICE
The SG BODY series light curtains efficiently satisfy all applications that require the Muting function thanks to
pre-assembled, pre-cabled and pre-aligned Muting sensors.
T-shaped models are available with integrated Muting sensors for bidirectional Muting, L-shaped models for
unidirectional Muting and linear models without integrated Muting sensors are available.
By means of Muting arms accessories, linear models can be converted into T-shaped models and L-shaped
models.
The muting arms, available in “T” and “L” versions, take advantage of retro-reflex sensors technology. This
version covers a maximum operating distance of light curtain of 3 m.
The integrated Muting solution with “L” configuration facilitates sensor installation and suits applications
requiring one-way object passage direction.
The integrated Muting solution with “T” configuration facilitates sensor installation and is ideal for applications
requiring a bidirectional object passage movement.
The linear models, presenting a specific connector allowing easy connection of the Muting sensors, are
recommended for difficult or particular applications.
Sensor positioning has to be carried out by the operator, respecting the precautions listed in the following
chapters.

2.6.2 Minimum installation distance
As shown in Figure 5, the safety device must be positioned at a specific safety distance. This distance must
ensure that the dangerous area cannot be reached before the dangerous motion of the machine has been
stopped by the ESPE.
The safety distance depends on 4 factors, according to the EN ISO 13855 “Safety of machinery - The
positioning of protective equipment in respect of approach speeds of parts of the human body”
Standard:
•Response time of the ESPE (the time between the effective beam interruption and the opening of the
OSSD contacts).
•Machine stopping time (the time between the effective opening of the contacts of the ESPE and the
real stop of the dangerous motion of the machine).
•ESPE resolution.
•Approaching speed of the object to be detected.
Figure 5
The following formula is used for the calculation of the safety distance:
S = K (t1+ t2) + C
Where:
S = Minimum safety distance in mm.
K = Speed of the object, limb or body approaching the dangerous area in mm/sec.
t1= Response time of the ESPE in seconds (see section 11 –“TECHNICAL DATA”)
t2= Machine stopping time in seconds.
d = Resolution of the system.
C = Additional distance based on the possibility to insert the body or one of body parts inside the
dangerous area before the protective device trips.
C = 8 (d -14) for devices with resolution ≤40mm
C = 850 mm for devices with resolution >40mm
Note: Kvalue is:
•2000 mm/s if the calculated value of S is ≤ 500 mm
•1600 mm/s if the calculated value of S is > 500 mm

10
When devices with > 40 mm resolution are used, the height of the top beam has to be ≥ 900 mm (H2) from
machine supporting base while the height of the bottom beam has to be ≤ 300 mm (H1).
If the safety light curtain must be mounted in a horizontal position (Figure 6), the distance between the
dangerous area and the most distant optical beam must be equal to the value calculated using the following
formula:
S = 1600 mm/s (t1+ t2) + 1200 –0.4 H
Where:
S = Minimum safety distance in mm.
t1 = Response time of the ESPE in seconds (see section 11 –“TECHNICAL DATA”)
t2= Machine stopping time in seconds.
H = Beam height from ground. This height must always be less than 1000 mm.
Figure 6
Practical examples
Let's suppose to have a light curtain with height = 500 mm
To calculate the distance of the device from the ESPE, in a vertical position, the following formula is used:
S = K*T + C
Where:
T = t1+ t2
t1= ESPE response time + SE-SR2 relay release time (max 80 ms)
t2= Machine total stopping time (e.g. 300 ms).
C = 8 (d -14) for devices with resolution ≤40mm
C = 850 mm for devices with resolution >40mm
d = resolution
In all cases, if K = 2000mm/sec then S > 500 mm. Distance will have then to be recalculated using K = 1600
mm/sec.

2.7 TYPICAL APPLICATIONS
The safety light curtains of the SG BODY Series are used in all automation fields where control and
protection of the access to dangerous zones is necessary, as well as allowing, by means of the Muting
function, material passage inside a dangerous zone during working.
In particular, they are used to stop the moving mechanical parts in:
-Access control
-Working areas
-Packaging machines, handling machines, storing machines;
-Automatic and semi–automatic assembly lines;
-Automatic warehouses;
-Robotics.
In food industry applications, Datalogic Technical Service has to verify the compatibility of the material of the
safety light curtain housing with any chemical agents used in the production process.

2.8 SAFETY INFORMATION
For a correct and safe use of the safety light curtains of the SG BODY series, the
following points must be observed:
•The stopping system of the machine must be electrically controlled.
•This control system must be able to stop the dangerous movement of the machine within
the total machine stopping time T as per paragraph 2.6.2, and during all working cycle
phases.
•Mounting and connection of the safety light curtain must be carried out by qualified
personnel only, according to the indications included in the special sections (refer to
sections 3, 4, 5, 7) and to the applicable standards.
•The safety light curtain must be securely placed in a particular position so that access to the
dangerous zone is not possible without the interruption of the beams (refer section 3 –
“INSTALLATION MODE”).
•The personnel operating in the dangerous area must be well trained and must have
adequate knowledge of all the operating procedures of the safety light curtain.
•The TEST button must be located outside the protected area because the operator must
check the protected area during all the Test operation.
•The RESET/RESTART button must be located outside the protected area because the
operator must check the protected area during all the Reset/Restart operations.
•The OVERRIDE buttons must be located outside the protected area because the operator
must check the protected area during all the Override operations.
•The external signaling lamp of the active Muting/Override must be visible from all operating
sides.
•Please carefully respect the mounting instructions for the correct functioning of the Muting
devices.
•The function of the external device monitoring (EDM) is active only if the specific wire is
correctly connected to the device.
•Please carefully read the instructions for the correct functioning before powering the light
curtain.

3 INSTALLATION MODE
3.1 PRECAUTIONS TO BE OBSERVED FOR THE CHOICE AND
INSTALLATION OF THE DEVICE
Make sure that the protection level assured by the SG BODY series device (Type 2 or Type 4
respectively) is compatible with the real danger level of the machine to be controlled, according
to EN 954-1 and EN13849-1.
•The outputs (OSSD) of the ESPE must be used as machine stopping devices and not as
command devices (the machine must have its own START command).
•The dimension of the smallest object to be detected must be larger than the resolution level
of the device.
•The ESPE must be installed in a room complying with the technical characteristics indicated
in section 11 - TECHNICAL DATA. Datalogic does not recommend the use of the product in
ambient where direct or indirect exposure to solar light is present.
•Do not install device near strong and/or flashing light sources or close to similar devices.
•Strong electromagnetic disturbance might negatively affect device operation. Should this be
the case contact DATALOGIC Technical Service.
•The operating distance of the device can be reduced in presence of smog, fog or airborne
dust.
•A sudden change in environment temperature, with very low minimum peaks, can generate
a small condensation layer on the lenses and so jeopardize functioning.
•The Muting/Override function is signaled by a specific Muting/Override signaling lamp.
Ensure that the signaling device has sufficient lighting and visibly positioned near the
dangerous zone.
•Ensure to correctly use Muting sensors as described in the instructions supplied
hereinafter. Avoid incongruent connections that cannot be controlled and thus excluding
undesired potentially dangerous activations.
