1.1.1 General Description of the safety light curtains
The safety light curtains of the SG4 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 SG4 series are Type 4 intrinsic 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/AC:
2010 Safety of machinery: electrosensitive protective equipment.
Part 1: General prescriptions and tests.
IEC 61496-2:
2006 Safety of machinery: electrosensitive protective equipment -
Particular requirements for equipment using active optoelectronic
protective
devices.

2008 (Cat.4, PL e) Safety of machinery. Safety-related parts of control
systems.
Part 1: General principles for design

electronic/programmable electronic safety-related control systems.
The device, consisting of one emitter and one receiver housed inside strong 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 a M12 connector located in the lower
side of the profile. 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 (see chapter 8 “
Diagnostic
”).
