1 GENERAL INFORMATION
1.1 GENERAL DESCRIPTION
The safety light curtains 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 are intrinsic safety systems used as accident-prevention protection devices and are
manufactured in accordance with the international Standards in force for safety, in particular:
NORM

Safety of machinery: electrosensitive protective equipment.

The device, consisting of one emitter and one receiver contained inside aluminium profiles, generates infrared
beams that detect any opaque object positioned within the light curtain detection field.
The emitter and the receiver are equipped with the command and control functions.
The connections are made through one or more connectors as specified in cfr.ELECTRICAL CONNECTIONS
page 24.
The synchronisation between the emitter and the receiver takes place optically, i.e. no electrical connection
between the two units is required.
The microprocessor guarantees the check and the management of the beams that are sent and received through
the units: the microprocessor –through some LEDs –informs the operator about the general conditions of the
safety light curtain (cfr.USER INTERFACE AND DIAGNOSTICS page 30).
The receiver is the main controller for all functions. It monitors all safety actions in case of failure and performs
general functions as well.
During installation, an user interface facilitates the alignment of both units (cfr.ALIGNMENT PROCEDURE page
27).
As soon as an object, or a limb 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 or trigger Safety State over connected
safety Fieldbus.

Some parts or sections of this manual containing important information for the user or installing operator are
preceded by a note:
This manual contains all the information necessary for the selection and operation of the safety devices.
However, specialised knowledge not included in this technical description is required for the planning and
implementation of a safety light curtain on a power-driven machine.
As the required knowledge may not be completely included in this manual, we suggest the customer to contact
Datalogic Technical Service for any necessary information relative to the functioning of the light curtains and the
safety rules that regulate the correct installation (cfr. USER INTERFACE AND DIAGNOSTICS page 30).
1.2 PACKAGE CONTENTS
Package contains the following objects:
Receiver (RX)
Emitter (TX)
Quick Guide of safety light curtain
Periodical checklist and maintenance schedule

Notes and detailed descriptions about particular characteristics of the safety devices in
order to better explain their functioning. Special instructions regarding the installation
process.

1.3 HOW TO CHOOSE THE DEVICE
There are at least three different main characteristics that should be considered when choosing a safety light
curtain, after having evaluated the risk assessment.
1.3.1 Detection capability
The detection capability (or resolution) of the device is the minimum diameter that an opaque object must have in
order to obscure at least one of the beams that constitute the detection zone and to actuate the sensing device.
The resolution is related to the part of the body to be protected.
R=14mm
finger protection
As shown in Fig 1 - page 8, the resolution only depends on the geometrical characteristics of the lenses, diameter
and distance between centres, and is independent of any environmental and operating conditions of the safety light
curtain.
Fig 1 - Detection capability
The resolution value is obtained applying the following formula:
R = I + d
where:
I=Interaxes between two adjacent optics
d=Lens diameter

1.3.2 Height of the detection zone
The controlled height is the height protected by the safety light curtain.

1.3.3 Minimum installation distance
The safety device must be positioned at a specific safety distance (Fig 3 - page 10).
This distance must ensure that the dangerous area cannot be reached before the dangerous motion of the
machine has been stopped by the Safety Control System.
The safety distance depends on 4 factors, according to the EN ISO 13855 Standard:
Response time of the ESPE (the time between the effective beam interruption and the opening of the OSSD
contacts)
Machine stopping time including Safety Control System computing and actuating time if present.
ESPE resolution
Approaching speed of the object to be detected
Fig 3 - Installation distance (vertical positioning)
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 cfr.TECHNICAL DATA page 36)
t2
=
Machine stopping time in seconds (including the Safety Control 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 (R -14) for devices with resolution ≤ 40 mm
C=850 mm for devices with resolution > 40 mm
R
=
Resolution of the system
K value 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
