EOS2 SAFETY LIGHT CURTAIN
INTRODUCTION
The EOS2 light curtain is an optoelectronic safety device belonging to the category of
Type 2 electro-sensitive protective equipment for the protection of personnel exposed to
risks inherent in the use of dangerous machines or plants, complying with the
IEC 61496-1,2 and EN 61496-1 standards.
The EOS2 is available in three different versions:
1. EOS2 A
Type 2 light curtain consisting of Emitter plus Receiver with automatic reset.
2. EOS2 X (With integrated control functions)
Type 2 light curtain consisting of Emitter plus Receiver with integration of additional
functions such as control of feedback from any external contactors and management of
manual/automatic operation.
3. EOS2 XM/XS (MASTER/SLAVE)
Type 2 light curtain (with integrated control functions) comprising two (or three) TX/RX
pairs (connected in series), one of which comprising the MASTER light curtain (with
integrated functions) and one (or two) the SLAVE light curtain.
A set of indicator leds on the Emitter and Receiver provide the information needed for a
correct use of the device and for the assessment of any malfunction. The automatic fault
sensing system permits independent detection by the EOS2 light curtain of any
dangerous fault in a time equal to the light curtain response time.
For any safety problem, if necessary, consult the safety authorities of the country of
use or the competent industrial association.
For applications in the food industry, consult the manufacturer to verify compatibility
of light curtain materials with the chemical agents used.
The protection capability of optoelectronic safety devices is not effective in cases in
which:
- The machine stopping device cannot be actuated electrically and it is not possible
to stop all dangerous machine movements immediately and at any time during the
operating cycle.
- The dangerous condition is associated with the falling of objects from above or
ejection of these from the machine.
- Anomalous forms of light radiation are present (for example, use of cablelless
control devices on cranes, radiation from weld spatter, etc).
In this case additional measures may be necessary to ensure that the ESPE does not
fail to danger.
