VERIFYING THE PROTECTED AREA
This should be performed using a cylindrical Test Piece with a diameter corresponding to the
detection capability of the device concerned. This must be intercepted anywhere within the
protected area, causing the green LED to light-off and the red LED to light-on.
The Output Signal Switching Devices (OSSDs) should also open, disabling operation of the
machine. A Test Piece, suitable for the device in use, should always be available near the work
station, to allow the every day verification.

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.

The choice between the two models must be made on the basis of the risk category attributed to
the machine, assessed in accordance with European standard . The
model is suitable for all applications with maximum accident risk, both in terms of the
frequency with which the operator is exposed to said risk and the gravity of the danger (machines
listed in annex IV of Directive 2006/42/EEC). The model is suitable for all other applica-
tions where the severity and frequency of exposure to the risk of accident is less.
To prevent shift of the laser light guard and consequently also of the protected area, it must be
fixed solidly and precisely respecting the instructions given in paragraph 13 "Mechanical Data".
so as
Connection cables must be arranged so as to avoid accidental contact with, for
example, abrasive, hot or sharp objects which could cause dangerous damage to the cables
themselves. In the event of damage to the connection cables, do not use the device and
disconnect immediately from the power supply. Avoid the connection cables coming into
contact with water or damp surfaces. In addition, prevent access to the danger zone with other
fixed material barriers where this is not possible by the use of electro sensitive protective devices.
The and housings are electrically connected to the ground of the internal circuit, thus to
the conductor of the connector. Contact between the housing and the chassis of the
machine (unless free of potential) must therefore be avoided. Failure to observe this precaution
could lead to damage of the units. This danger is totally avoided if the sensor units are correctly
fixed using special supports in electrically insulating material. Connection of other equipment to
the power source used to power the "RED-RL" device is not recommended. This could generate
electrical disturbance, jeopardising correct operation of the various parts of the device itself. If
liquid or foreign bodies of any kind penetrate into the device, stop using it immediately and
disconnect it from the power supply. The “RED-RL” device has been designed and produced in
such a way that the housing does not have to be opened for the device to be used. Given the
particular function of the device itself, removal of the heads of the aluminium housings of the
transmitter TX and receiver RX is prohibited. No attempt should be made to repair them. Always
contact the manufacturer only.

Verify that the available power supply source corresponds to that operating one of the device in
use that must be verified from the data plate of both sections Transmitter (TX) and Receiver (RX).
The presence of a visible light laser emission, even if of low power as established by the enforced
european norms, could cause the use of the device dangerous. The protection of the person eye
from accidental flash turns out however assured, also without particular precautions, by the own

STARTRESTARTINTRLOCK
EXTERNAL DEVICE MONITOR
MUTING
RED-RL safety devices can be easily setted, without making any internal modifications, to switch
from the automatic restart to the manual restart operation with start-restart interlock by a remote
push-button (Pag.13 - Fig.15/16).
In automatic restart operation the Receiver control logic, without consents from the outside, auto-
matically drives the two output signal switching devices to the active ON state every time that the
laser beam emitted from the Transmitter catches up the four sensing elements of the Receiver af-
ter that the same one has been interrupted from an obstacle. Instead, in the event in which the de-
vice comes setted for manual restart operation, every time that the laser light beam comes inter-
rupted is necessary to supply, for example by a push-button or a safety-pedal, an external input si-
gnal on the respective dedicated YELLOW color conductor (see paragraph 12.1 “Electrical con-
nections - RX”) that it qualifies the control logic of the Receiver to bring back to the active ON sta-
te the output signal switching devices after a switching OFF of the same ones as a result of an in-
terruption of the laser light beam.
An External Device Monitor (EDM) control loop circuit allows, the safety RED-RL guard, to control
the state of the correct operation of the devices (eg. relé, contactors, etc) externally connected to
the two outputs as a load, thus extending the safety level up to the machine primary control
elements. To such scope the Receiver, of the laser guard, is provided of the YELLOW color input
conductor who make head to the inside EDM circuit.
Between this conductor and ground, “0V” of power supply, has to be in series connected the
normally open switches of the external output load devices thus from being able to test their own
efficiency as a consequence of every actuation (passage from ON to the OFF state) of the barrier
for the interruption of the laser beam. In the event in which such function it does not used, it is
necessary to connect the conductor YELLOW to the ground “0V” of power supply.
For the “RED4-RL” Laser guard model, the “Neutralization” or “Muting” function is also
previded, that is the possibility of being able to suspend in temporary way its own
protecting function. That it means that when the two dedicated inputs are simultaneously
activated (within a maximum time of 0,8 second) putting separately in short-circuit the
PINK and GRAY conductors to the “0V” of power supply (RED conductor and Shield), the
Laser Guard surveillance action comes temporarely neutralized, allowing that the Laser
beam can be darkened without that the output signal switching devices (OSSDs) switch
to the inactive OFF state. A red color blinking signaler, situated on the top head of the “RX”
section (Pag.8), shows the activation of the Muting function. In the event of the two
dedicated muting inputs are not simultaneously activated, or however with a time delay
more than 0,8 second, the RED4RL switches into the block state opening the output
signal switching devices (OSSDs) and signaling it as the “D” case of the diagnostic table of
Pag 8.
. Adopt a visual and/or acoustic to indicate in
unequivocal way the inactivity state of the Barrier to activated Muting.
Make attention using this function as it could generate potentially dangerous
situations additional external signaler

To ensure the device fulfils its accident prevention functions correctly, it must be installed at a
safe distance from the point actually dangerous for the operator of the machine in such a way as
to stop the dangerous movement before that point is actually reached.
The procedure for calculating this distance is established in the harmonised European standard
which gives a number of formulas using parameters dependent on various
factors discussed below (for more detail see the standard itself).
For information only, a number of examples to calculate the installation distance from the danger
point for vertically-installed light curtains with a detection capability of no more than 40 mm are
given below:
is the safe distance to be respected when installing the device
is a constant establishing the speed at which the operator approaches the danger point,
established at 2 meters per second
is the time in milliseconds deriving from the sum of the time t1 taken by the machine to stop
its dangerous movement after an ALT command and the time t2 taken by the light curtain to
open the OSSDs after an obstacle has been introduced into the protected area.

All models of the "RED-RL" active optoelectronic at Laser emission are calibrated during fac-
tory testing according to the specified by the customer in the last part of the
order code. Should it be necessary to modify this distance at a later date, you should contact
the manufacturer who will modify the calibration for the new working distance. Alternatively,
contact the factory telephonically for instructions on how to proceed.

For the Laser guard model, the “Neutralization” or “Muting” function is also previded, that is the possibility of being able to suspend in temporary way
its own protecting function. That it means that when the two dedicated inputs are simultaneously activated (within a maximum time of 0,8 second) putting
separately in short-circuit the PINK and GRAY conductors to the “0V” of power supply (RED conductor and Shield), the Laser Guard surveillance action comes
temporarely neutralized, allowing that the Laser beam can be darkened without that the output signal switching devices (OSSDs) switch to the inactive OFF state. A
red color blinking signaler, situated on the top head of the “RX” section (Pag.8), shows the activation of the Muting function. In the event of the two dedicated muting
inputs are not simultaneously activated, or however with a time delay more than 0,8 second, the RED4-RL switches into the block state opening the output signal
switching devices (OSSDs) and signaling it as the “D” case of the diagnostic table of Pag 8. Make attention using this function as it could generate potentially
dangerous situations. Adopt a visual and/or acoustic additional external signaler to indicate in unequivocal way the inactivity state of the Barrier to activated Muting.

The Transmitter and Receiver units do not require particular maintenance. However, the frontal
heads of the two sections protective of the optics, with the holes for exit and entrance of the laser
light beam, should be cleaned daily to remove large quantities of dust.
Avoid rubbing the screens with abrasive cloths as rubbing causes static electricity and attracts
dust. To clean, use alcohol. Avoid plastic solvents.
When the device is used for the first time, to guarantee safe conditions, the correct setting of the
functions must be controlled. When using the device for the first time, operation of the device in
the particular application must first be verified. This must be done by specialist personnel. Acci-
dent prevention legislation specifies that this control should be performed daily.
Before beginning any form of work, it is good practice to verify that:
with the machine stationary and power to the laser guard on (no obstacle in the protected
area), the green indicator is lit.
with the machine stationary and power to the on in the presence of an obsta
cle in the protected area, the red indicator is lit.
moving parts are not accessible to personnel. Any extraordinary maintenance must
therefore be carried out under the strict supervision of the safety manager. All accesses
not pro tected by electro sensitive protective devices must be equipped with fixed material
barriers or other.
A sheet indicating the daily checks must be compiled by the operator of the machine and must
be clearly visible near the workstation.
