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.

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”).
