correct installation.
The barrier does not contain any parts that are subject to maintenance;
the power supply must be disconnected before proceeding with any
external intervention.
In case of malfunction, it must be sent to our laboratories with a
description of the anomaly found and its period of operation.
Any deterioration in the protective covers does not compromise the
system’s safety in any way but may cause it to stop operating.

GENERAL DATA AND MAIN APPLICATIONS
SB units are safety barriers used for the protection of persons in
environments where it is essential to safeguard the safety of the operator
using machinery, robots or dangerous automated systems in general or
where casual and/or unauthorised access may be gained to hazardous
parts.
These appliances provide coverage of the protected area and generate a
beam of infrared rays, which are able to detect an object located inside
their field of operation.
They comply with the requisites for level 2 (SB2 series), and level 4 (SB4
series) safety appliances according to the provisions of the latest
international regulations and IEC 61496 1-2 in particular.
Models are available that provide an area of protection with heights
approximately between 150 mm and 1650mm.
All the control and command functions are contained inside the profile;
connections are made using a connector underneath the barrier. There are
no connections between the transmitter and the receiver, as synchronism
between the two parts is guaranteed optically. Control and management of
the rays issued and received is guaranteed by two microprocessors that
also provide information on the status of the barrier by means of several
leds. There are two alignment leds to aid installation.
The
muting and override
function is available for all the SB barrier models
and is enabled by simply connecting the LMS luminous warning light,
supplied separately.
Versions are also available with the
floating blanking
function: this function
offers the possibility to partially exclude a predetermined floating portion of
the barrier.
Muting, override
and
floating blanking
all effectively override the system
and therefore certain precautions have been put in place to limit the
deterioration of the level of safety when these functions are operational.
