INFORMATION
1.1. General description of the SAFE
asy
TM
safety light curtains
The
SAFE
asy
TM
safety light curtains of the SE4-PLUS series, are
optoelectronic multibeam devices that can be used to protect
working area that, in presence of machines, robots, and automatic
systems in general, can become dangerous for operators that get
in touch, even accidentally, with moving parts.
The
SAFE
asy
TM
light curtains of the SE4-PLUS 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:
IEC 61496-1
:
2004
Safety of machinery:
electro-sensitive protective
equipment. Part 1: General
requirements and tests.
CEI IEC 61496-2
:
1997
Safety of machinery:
electro-sensitive protective
equipment. Particular
requirements for equipment
using active optoelectronic
protective devices.
The device, consisting in one emitting and one receiving units
housed inside strong aluminium profiles, generates an infrared
beam array that detects any opaque object positioned within the
light curtain detection field.
The emitting and the receiving units 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 microprocessors guarantee the check and the management
of the beams that are sent and received through the units: the
microprocessors – through some LEDs – inform the operator
about the general conditions of the light curtain and about
eventual faults (
see section 7 “Diagnostic functions”
).
