The safety device “RED-RL” is an intangible Barrier with a visible light laser emission that in
coupling to the machine control system supplies protection from accidents to the operator uses
in it of the same one. It is composed by a Transmitter (TX) and a Receiver (RX)
. The Control
Logic of the Receiver drives the two outputs to the active state ON when all the sensing elements
are illuminated from the red light laser emitted from the Transmitter, while the outputs are drived
to the inactive state OFF in the event in which the intrusion of any opaque element inside of the
survey area it prevents that just one of the sensing elements can be illuminated from the laser
light beam. The function of the device is therefore that to inhibit to the command elements of the
machine the consent to the operation in the moment in which there are not the safety conditions
to operate. Any improper use of the device must be thought thus prohibited cause the
consequent loss of any form of explicit and implicit warranty, like every responsibility from the
manufacturer for eventual damages and accidents that could be taken place.
In order that the laser guard “RED-RL” can work in the more appropriate way it is fundamental that
it is correctly installed, tested and used as it follows.
INSTALLATION
units
The "RED-RL" device has been designed and manufactured with the aim of eliminating or
reducing as far as possible all risks for the user.
However,
could result in
unforeseen conditions with some degree of danger which cannot be completely eliminated.
Installation, testing and maintenance of the "RED-RL” device must be performed exclusively by
qualified personnel following the instructions in this manual faithfully and meticulously.
Ensure the two units, Transmitter (TX) and Receiver (RX), are perfectly parallel, and fixed, using
the supplied means, at the working distance specified when ordering and reported on the rating
plate under the heading "Working Distance". Keep the Receiver out of direct sunlight. The
equipment is turned on by powering the transmitter TX and receiver RX according to the
information given on the rating plate. After about one second the device should be ready for
operation.
The meaning of the light indicators is described and illustrated in detail in paragraph 8
". After turning power to the two units on, and aligning them
correctly, make sure that the green
indicator on the Receiver is on. The red
indicator,
on the RX, lights on in the presence of an obstacle inside the protected area or if the units are not
perfectly aligned. To prolong the connections, use shielded cable to avoid any kind of
interference. If there are shiny reflectant surfaces near the light curtain, they should ideally be
coated with matt black paint to reduce the risk of undesirable reflections.
At the end of the installation, also verify correct operation of the devise using the test piece to
ensure it is intercepted at all points of the area to be protected. The minimum diameter of the test
piece unequivocally intercepted at all points of the protected area is known as the Maximum
Detection Capability (from CEI-EN 61496 standard) of the light curtain. For example, for the
“RED-RL” series this is greater or equal to14 mm.

indicators and setting controls - RX
From the frontal head of TX section a visible light laser beam has to come out and has
to illuminate the frontal head of RX section with references for the correct alignment in
correspondence of the four light incoming holes to the sensors (Pag.9 - Fig.9). Eventually
improve the alignment of the two sections in the event the laser beam did not have to perfectly
illuminate the zone of the references.
