GENERAL INFORMATION
1.1. General description of the SAFE
asy
TM
safety light curtain
The
SAFE
asy
TM
safety light curtains – SF2 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
SAFE
asy
TM
devices are Type 2 intrinsic safety systems used as
accident-prevention protection devices and are manufactured in
accordance with the international Standards in force for safety, in
particular:
CEI EN 61496-1
:
2004
Safety of machinery: electro-
sensitive protective equipment -
General requirements and test.
CEI IEC 61496-2
:
1997
Safety of machinery: electro-
sensitive protective equipment -
Particular requirements for
equipment using active opto-
electronic protective devices.
The device, consisting in one
emitting and one receiving unit
housed inside strong aluminium
profiles (Fig.1), generates infrared
beams that detect any opaque
object positioned within the light
curtain detection field.
The emitting and the receiving
units are equipped with command
and control functions (no external
control unit is required).
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.
