1 OPERATION
The Safety Light Curtain (SLC) is made up of one active side with
transmitter and receiver optical elements called the transceiver and one
completely passive side, with a mirror system.
The operator has a multifunction pushbutton, which is used for the
following:
• TEST: If pressed during normal operation, it checks if all of the
system, comprising of the SLC and the machine is working.
Pressing the TEST button (opening the contact) basically simulates
the interruption of one or more safety beams and it is possible to
check that the machinery stops in the correct time and
configuration.
• RESTART: If pressed after an intervention by the SLC, (manual
reset condition) the system will be reset.
• ALIGNMENT: If the button is pressed when there is no power supply
to the SLC and then power is restored, whilst the button is being
pressed, it enters alignment mode, i.e. it provides an indication of the
alignment position of the unit by means of two yellow LEDs.
• OVERRIDE: (only present if the muting function is operational) if the
button is pressed within 5 seconds of switching on and it is kept
pressed for at least 5 seconds, the SLC will close the safety outputs
if the beams are interrupted. This condition stops as soon as the
button is released or automatically after 120 seconds.
1. Automatic reset: After the SLC has detected an object, it returns to
normal operation as soon as the object is removed.
2. Manual reset: Normal operating mode is only restored after the object has
been removed and the reset button has been pressed.
To enable the muting function, the LMS muting indicator must be
connected when the SLC is not connected to the power supply, as
shown in section 6, and then the SLC’s power supply must be restored. To
disable the muting function, the LMS muting indicator must be
disconnected when the SLC is not connected to the power supply, and
then the SLC’s power supply restored.
Please remember that by enabling/disabling the muting function the
override function is automatically enabled/disabled.
The outputs are PNP type.
Should the load to be controlled have alternating current or require more
than 500mA consumption, it is necessary to use an external safety relay
module.

2 PRECAUTIONS AND CRITERIA FOR INSTALLATION
The area where the SLC is to be installed must be compatible with the SLC
‘s technical specifications. The temperature of the environment, interference
caused by electromagnetic disturbance and sources of light and such like,
should be assessed a competent person. Please contact the manufacturer
for any information not contained in this manual.
2.1 CALCULATION OF THE MINIMUM DISTANCE FOR INSTALLATION
The safety distance ‘S’ must guarantee that the operator cannot reach the
danger zone before the machinery with the moving parts has stopped. The
formula to calculate the safety distance for multi-beam SLCs is as follows:
S = (K * T) + C
S = safety distance.
T = T1 + T2
where T1 = machinery’s response time in seconds.
T2 = SLC’s response time in seconds.
K = 1600 mm/s (approach speed of the body to the danger zone).
C = 850 mm
S= safety distance.
H1 = the bottom optical beam must not have a height above 400 mm.
H2 = the top optical beam must not be below 900 mm.
Number of beams Heights above the reference plane, e.g. ground in mm

2.2 REFLECTING SURFACES
Be sure to install the SLC to minimize the effect of reflection from
nearby surfaces. Serious injuries can result if these effects are not
taken into consideration.
Should there be any reflecting surfaces, the distance must be sufficient to
safeguard against passive reflections.
The distance can be calculated following the table below:
where ‘D’ and ‘L’ are expressed in m
reflecting surface
L distance between SLCs Minimum permitted installation
distance D
0.5 to 3 m 0.13m
Over 3 m L/2 x tan5° = L/2 x 0.088 (m)

If several SLCs are used, care must be taken that each SLC does not
interfere with the ones nearby; please install as follows:
Mirror1 SLC1 SLC2 Mirror2
Install the SLC so that they emit in the opposite directions (Staggered)
SLC1 Mirror2 SLC1 Mirror1
Mirror2 SLC2
Mirror1 SLC2
All these installation will prevent mutual interference between SLC.

4.2 NOTES ON CONNECTIONS
• The transformer needed to power the system must comply with
standard EN 60742 (dual isolation), or with equivalent isolation,
e.g. VDE 0551.
• The control unit must be protected with an external fuse, whose
rated breaking current must be 1A.
• The TEST/RESTART button must be located so that the
operator can see the protected area when restarting, testing or
overriding.
• The external illuminated indicator for muting override enabled
must be located so that it can be seen from all sides of
operation.
• Read the section on the muting function and its use before
locating the sensors for the activation of this function.
• Check that the load does not absorb current in excess of
500mA; in this case a protection device will intervene to limit the
maximum current. If loads with currents in excess of 500mA
and up to 6A alternating current are to be controlled, please
connect an external safety relay module.
• Muting input A and Muting input B can be provided by
mechanical switch, photoelectric sensors, proximities switch,
with closed contact in the presence of the object to be detected.
• The test connection must always be executed with a N.C.
button or connected to an automatic device, such as a PLC.

5 ALIGNMENT PROCEDURE
After completing correct mechanical assembly and connections, as
described in the previous sections, the SLC should be aligned as follows:
• Disconnect the SLC’s power supply.
• Open the test/restart contact.
• Restore the SLC’s power supply.
• Adjust the direction of the SLC by moving the transceiver or the
mirror. The 2 yellow LEDs located on the transceiver will both be
lit when the SLC is aligned correctly. In addiction also the green
guard LED will switch on and the red break LED will switch off
• After aligning the SLC, secure the bolts firmly.
• Disconnect the power supply.
• Restore the SLC’s power supply (with the test contact closed); it
will enter operating mode.
• Complete all the tests described in section 9 (final checks) and
those required for routine maintenance (section 10).

7 MUTING AND OVERRIDE FUNCTIONS
7.1 GENERAL INFORMATION
The muting and override functions enable the SLC to be bypassed for
operational requirements. As required by current standards, the SLC is
provided with inputs for the activation of these functions. It should however be
remembered that these functions basically override the system and they
should therefore be used with due care.
7.2 MUTING FUNCTION
As mentioned in the introduction, the muting function can be enabled with any
SLC by simply connecting the LMS muting indicator when the SLC is switched
off.
The presence of this indicator is recognised when the SLC is switched on. If
its presence is detected, the SLC will enable the muting function and if it is not
present the SLC will ignore any request for muting. It is important to note
that if the muting indicator is connected when the SLC is already
connected to the power supply, it will not be recognised and the muting
function will not be enabled. Once enabled, if the LMS muting indicator
develops a fault or is removed without first disconnecting the SLC’s power
supply, it will signal an error with the muting light, as described in section 10.
To disable the muting function, the power supply must be turned on without
the LMS muting indicator connected.
In brief: this function, present on all SLC s, is enabled and disabled by means
of the following simple procedure:
- Disconnect the SLC’s power supply.
- Connect the appropriate LMS muting indicator and the muting
sensors (see section 6)
- Restore the SLC’s power supply.
Bypass the muting function as follows.
- Disconnect the SLC’s power supply.
- Disconnect the LMS muting indicator and the muting sensors (see
section 6)
- Restore the SLC’s power supply.

7.3 PARTIAL MUTING CONFIGURATION.
This feature is available only on the F3S-TGR-SBx-K3C and F3S-TGR-SBx-
K4C models.
It gives the users the opportunity to mute only half of the light curtain. The
other half remains active.
The configuration of this function is done by setting the internal dip switches 1
& 2.

7.4 CRITERIA FOR INSTALLATION
Take adequate care when installing the muting sensors to prevent undesired
requests for muting:
1. Wiring must be done correctly.
2. The muting sensors must recognise the whole length of the material (i.e.
pallets, vehicles...).
3. The sensors must be arranged so that the material is also recognised if it
has to be lifted for processing.
4. The effect of various transportation speeds in the field of muting on the
overall duration of muting must be taken into account, if any.
5. All the safety photocells and muting sensors must be arranged so that
the previous material clears the last muting sensor before the new
material reaches the first sensors
Example of conveyor protection installation, which must allow a box to pass through
but not a person. The SLC Sis connected to the control panel, and A1, A2, B1 and
B2 are sensors used to enable muting. The contacts for these sensors are controlled
on the transceiver unit.
Sensors A1, A2, B1 and B2 can be optical, mechanical or proximity sensors etc., with
closed contact in the presence of the object to be detected.

Where:
D: minimum dimension of package that can cross the SLC.
D1: distance between muting actuator B and SLC.
It MUST be as short as possible.
Minimum distance allowable depends on the speed of
conveyour, the response time of SLC and response time of
muting actuator.
D2: Distance between muting actuator A and muting actuator B.
It must be > 250mm
It also depends on the conveyour speed:
25 > dmax [cm]= v[m/s] * 3[s] * 100
It is necessary that this distance does not allow both sensors to
be activated and thus muting if a person goes through by
accident.

• The TEST/RESTART button must be located so that the operator can
see the protected area when restarting, testing or overriding.
• The external illuminated indicator for muting override enabled must
be located so that it can be seen from all sides of operation.
• If the muting sensors are installed very close to the SLC, care must
be taken that the receivers of the sensors are mounted on the
mirror side of the SLC in order to avoid interference.
• The system is protected against the possibility of faults due to
damage to the wires; however we recommend laying the cables for
all connections in order to avoid damage to the connection cables.
7.5 TIMING CONSTRAINTS (muting function)
a) The muting request must take place with the correct timing
sequence: the Muting A input must be enabled first and then the
Muting B input. The request for the latter must be made within a
maximum of 3 seconds and not before 30 ms (TM) after enabling
Muting A input. Otherwise the muting function will not be enabled.
An incorrect sequence on the muting inputs will not start the muting
process.
b) Muting status can be maintained for an unlimited period of time as
long as the muting signals are valid.

7.6 Timing constraints (for SLCs with postfix “–MTL” at the ordering
code)
a) The muting request must take place with the correct timing
sequence: the Muting A input must be enabled first and then
the Muting B input. The request for the latter must be made
within a maximum of 3 seconds and not before 30 ms after the
enabling of the Muting A input. Otherwise the muting function
will not be enabled. An incorrect sequence on the muting inputs
will not start the muting process.
b) There are 5 seconds maximum from the activation of muting to
the package entrance in the protected area by interrupting the
SLC. If this time is exceeded, muting function will stop
immediately.
c) As long as a package interrupts the protected area (at least one
beam), the muting function is maintained
d) Muting status can be maintained for an unlimited period of time
as long as the muting signals are valid.

7.7 OVERRIDE
This function makes it possible to override or bypass the system. It
is used to start up the machine after the material has interrupted one
or more of the SLC beams and to free the protected area from any
material that is present in front of the SLC,
If a pallet has stopped in front of the protected area, it will not be
possible to restart the conveyor belt because the SLC detects one or
more beams have been interrupted and therefore will not close the
outputs; therefore the protected area cannot be cleared.
However, it can be cleared if the override function is enabled.
This function can be used for all SLCs with the LMS muting indicator
connected, as described in section 3.
7.7.1 ENABLING THE OVERRIDE FUNCTION
• Switch the appliance off.
• Switch it on again and press the test/restart button within 5
seconds, keeping it pressed for at least 5 seconds.
• The override function is now enabled. The LMS muting
indicator flashes to signal the exclusion of the SLC.
• The maximum duration of the override function is 120 seconds,
after which the SLC is reset, even if the button is kept pressed.
Naturally, if the button is released before this, the override
function will terminate immediately.

9 FINAL CHECKS
• Check that the area protected by the SLC is free of obstacles.
• Check that the safety outputs open correctly by interrupting the
protection beams (BREAK LED lit, machinery under control stops).
10 ROUTINE CONTROLS AND MAINTENANCE
These checks are recommended and should be carried out on a
regular basis by qualified personnel:
• Check that the SLC remains blocked by inserting an object that
intercepts the beams along the entire length of the protected area.
• Check via the opening of the TEST/RESTART contact, that the
safety relays open (red LED lit and controller machinery stopped).
• Check that it is not possible to access the danger areas of the
machinery from any area that is not protected and that the
minimum distance between the dangerous areas and the SLC is
no less than that calculated as per formulas 4.1 and 4.2.)
• Check that it is not possible for a person to get between the SLC
and the dangerous parts of the machinery.
• Check that there is no external damage to the SLC and/or to the
external electrical connections.
The interval between the above actions depends on the individual
application and the conditions in the environment where the SLC is used.
