3.0 DESCRIPTION OF THE PRODUCT
3.1 Brief description
The LS4 series safety light curtains are multi-beam optico-electronic safety evices, built in compliance with the IEC
61496-1 an 2 stan ar s, are Type 4 an therefore applicable for the protection of the operators of systems or
machines un er con itions of frequent interaction with a severely angerous area.
LS4 safety light curtains have a slim profile of 28x30mm, the istance of 28mm refers to the front si e, they have a
rear groove for fastening, they are extremely reliable evices, they provi e two protecte static safety PNP outputs,
so they are not subject to output contact wear or affecte by strong vibration, they are able to etect internal faults,
control external contacts an , in the event of a fault, ensure safe behaviour in any case.
With a free area the level of the two outputs is enable to be high (status ON, outgoing current), with an occupie area
or in case of fault the level is low (status OFF).
The emitters have a Test input, that can be use if the user wishes to check the equipment connecte ownstream
from the safety light curtain (without physically intervening insi e the protecte area), the control stops the emission of
the beams on the projector an enables switching the OSSD from the ON state to the OFF state as long as the control
is active.
There are mo els with ifferent resolutions (minimum etectable iameter) e icate to certain etection of han s,
limbs an bo y; the ifferent resolution for mo els of the same type enables choosing ifferent safety istances.
Safety light curtains are available with resolutions of 14, 20, 30, 40, 50, 90 mm, heights from 160 to 1510mm,
maximum ranges of 3, 4, 10, 12m. Multi-beam safety light gri s are available with 2, 3, 4 beams e icate to access
control.
The Base an standard mo els can be use in ivi ually, the Master, Slave an Final Slave mo els can be use in
a chain of two or three elements, also with ifferent types of optics; this enables creating complex applications in a
simple cost-effective manner, for highly integrate protecte zones even with ifferent resolution or range
requirements.
The Base mo els have only the automatic restart function without controlling the external contacts (EDM).
On the standard an Master mo els it is possible to combine all the functions by wiring as preferre : external
contact control (EDM), automatic starting, manual starting.
All the mo els use M12 connectors with 5 or 8 poles, for the supply/output cables an the interconnection cables
in a chain no shiel ing is require , the output cable can reach lengths of 100m, the interconnection cable 50m, these
features also allow great operational flexibility.
The require operational voltage is 24V
DC
±20%, the absorbe power is mo erate, at most 3W per pair; the
maximum output current is 400mA, suite to rive even power contactors irectly; the blocking functions on restarting
an EDM, present on the standard an Master mo els, enable making versatile an integrate protection systems.
Normally, the environmental protection is IP65+IP6 , suitable also for usty environments or compatible with
phenomena of con ensation, except for the front surface that has strict optical requirements.
Mo els are available with IP69K protection that can be subjecte to washing with jets of hot water up to 80°C an
pressure up to 80 bar; with this level of protection mo els are available with an integrate thermal auto-control system
that moreover enable working at temperatures as low as -25°C an avoi ing con ensation on the optics.

4.0 INSTRUCTIONS FOR POSITIONING THE SAFETY LIGHT CURTAINS
4.1 Respecting the safety distance
A safety istance must be maintaine between the protection surface compose of the beams of the
safety light curtain
an the point of anger.
This istance must ensure that, consi ering a maximum approach spee efi
ne by the stan ar , the point of anger
can only be reache when sufficient time has elapse so that the angerous state of the machine has en e .
The safety distance in accordance with EN ISO 13855 depends:
- in irect proportion on the total time for
stopping the machine or system, which correspon s to the sum of the
in ivi ual times of reaction of the whole safety chain (the in ivi ual response times are in icate in the technical

height.
If the machine is subject to a specific stan ar of type C, the in ications of this stan ar must be followe .
Danger of failed recognition!
Particularly in access protection applications, people may stop in the anger area, but not in the optical
beam between the projector an the receiver, an their presence might not be recognize .
Make sure that angerous states can only occur when there are no persons in the anger area.
Make sure that the system Restart control is effecte from a point provi ing full visibility of the anger
area an that this control cannot be reache from within sai area.
No protection function is secure if the safety distance is not correct!
It is in ispensable to mount safety light curtains at the correct safety istance to ensure the function of
protection.
If there is a C
-
type standard for the application you are creating, follow its instructions!
The following instructions apply only to an in ustrial environment, that is to say where only a ults of
normal constitution are expecte to be present.

4.2 How to calculate the safety distance S in conformity with EN ISO 13855 and EN ISO 1385
Here we give the general proce ures for calculating the minimum safety istance S
, these instructions must be followe
if there is not a specific stan ar of type C for the machine to make safe.
Depen ing on the application it is necessary to use ifferent calculation schemes.
In general the formula has this form:
S = K * T + C
Where…
S = [mm] Safety istance
K = [mm/s] Approach spee , a spee of 2000mm/s is in icate for the upper limbs an 1600 for the lower limbs.
T = [s] Total stopping time: response time of the entire safety evice + machine stopping time.
C = [mm]
Safety istance supplement, to ensure that the angerous zone cannot be reache by climbing over the
beams or inserting limbs between the beams. It is provi e by the stan ar , it takes on
a fixe value or is calculate
accor ing to the optical features of the safety light curtain an its utilization in the application.
The reaction time of the safety light curtain alone is stated on the product label of the
Receivers and in this document in the tables of Chap.:9.
In the case of a chain connection the reaction time of the safety light curtains corresponds to
the sum of all the individual times of the Receiver elements in the chain.
The standard considers different methods of approach:
1) PERPENDICULAR APPROACH
Safety light curtain in vertical position.
Angle between safety light curtain an surface of 90° ±5°
2) PERPENDICULAR APPROACH
Safety light grid in vertical position.
Angle between safety light curtain an surface of 90° ±5°
3) HORIZONTAL APPROACH
Safety light curtain in horizontal position.
Angle between safety light curtain an surface of 0° ±5°
4) OBLIQUE APPROACH
Safety light curtain in angled position.
Two cases are consi ere for ifferent angle values α

curtains
over
which it is possible to climb.
If a safety light curtain
is installe without any supplementary mechanical protection on the top, an therefore it is
possible to enter the protecte area from above, it is necessary to efine the safety istance consi ering two metho s:
- Access from above.
- Access through the beams.
-
Access from below, not consi ere now, can be exclu e if the lowest beam has a maximum height of 200mm from
the surface, or by installing mechanical protection.
The safety i
stance, consi ering access from above, must be such as not to allow reaching the anger area; this safety

5.0 MINIMUM DISTANCE FROM REFLECTING SURFACES
The optical beams of the projector, having a beam angle that is not null, can partly be iverte by reflective surfaces
locate near to the safety light curtain
. This may mean that a break in the irect path of the optical beam is not
etecte , which is why all reflective surfaces an reflective objects (in any position they may have with respect to the
controlle area, above, un er, insi e or outsi e) must respe
ct a minimum istance from the irect path of the beams of
the safety light curtain.
Indication
It is likewise important to respect the minimum istance between the projector an receiver in icate by
the manufacturer, in some cases the minimum istance may be greater than zero, especially for long-
range mo els.
At smaller minimum istances than the ones state , the beam angle may have an unpre ictable brea th
an so the safety istance may not be efinable with certainty.
When using iverter mir
rors, consi er that the minimum istance from reflective surfaces must be
respecte for all the rectilinear segments of the beams, consi ering the si es both insi e an outsi e the
protecte zone.
A reflective surface is any shiny surface, even a black one.
Any amage or opacification of the optics or inclusion of slabs of transparent or, even worse,
semitransparent material on the optical path can pro uce an increase in the beam angle.
Checking the capacity of etection with the test ro , performe in the
mi le an at the en s of the
controlle area, is an effective proce ure to exclu e the presence of angerous reflections, see also
Chap.:12.4.
5.1 How to calculate the minimum distance from reflective surfaces
Safety light curtains LS4 respect the maximum beam angle efine by IEC / EN 61496-2 for Type 4 (a/2=±2.5°),
or
less.
The safety istance D is calculate consi ering the entire beam angle a=5° an the safety light curtain
reciprocally
orientate towar s the reflective surface by an angle a
, in this way we consi er the case of alignment at the limit of
reciprocal visibility between the emitter an receiver, but which is more angerous ue to the effects of the reflection.
The safety istance D to take P ≥3m is calculate as follows:
D=tan(5°)*P/2 = 0.08 5*P/2
For ranges less than 3m the value calculate at 3m applies:
D = 0.08 5*1.5=0.131m
Fig.:1; Chap.:5; this figure shows the worst bor erline case that can occur: safety light curtain not perfectly aligne ,
but tilte by an angle a/2 towar s a reflective surface .
Fig.:2; Chap.:5; minimum istance “D” to maintain for the reflective surfaces in relation to the range “P”.

6.0 COMMISSIONING
6.1 Mechanical mounting
This evice is suite to work in protecte environments, not out oors.
It is extremely important to secure the safety light curtain to a rigi structure, not subject to eformation or strong
vibration.
Choose the position of the receiver so as not to subject it to strong sources of natural or artificial light or to luminous
interference by other sensors.
Mount the emitter an receiver facing each other, at the same height off the reference surface an with the same
orientation (refer to the BASE si e that is the isplay si e), the reciprocal istance must be within the fiel of the
specification. To secure the safety light curtain to a support use the specific inserts to apply to the rear groove an the
brackets normally provi e .
If there is vibration in the application, but still compatible with the optical alignment, use the amping supports
available as accessories.
In this phase classic tools such as a plumb line an /or a spirit level may be useful.
To facilitate the first phase of alignment, it is possible to use the specific LASER STL 01 S accessory for safety light
curtains with a profile of 28x30mm.
Temporarily block the emitter an receiver so they are aligne with an parallel to each other.
Danger!
To perform the next steps it is necessary to power the emitter an receiver, make sure that uring this
phase the machine's movements are blocke irrespective of the state that the receiver will take on; an
effective manner to obtain this is to physically cut off the supply to the actuators by permanently
isconnecting their supply cables.
6.2 Alignment
1) When switching on the LED 1 of the emitter will be RED for the uration of the power-on, if afterwar s the LED
makes two short GREEN flashes the High range function is active, if the LED makes 2/3 RED flashes, the TEST is
probably open an there is no emission (jumper TEST to procee ), if the LED is illuminate GREEN it means that the
emitter is working. In case of ifficulty with alignment it is a visable to temporarily activate the High range function, if it
is not alrea y enable , so as to facilitate it. Refer to Chap.: 6.3 to verify the emitter an receiver configuration mo e
an to Chap.:8 for the meaning of the in ications.
2) If it is possible to choose or temporarily change the configuration of the receiver, it is a vise to use the “Automatic
Restart without EDM” mo e, that is able to clearly signal the state of LIGHT an outputs ON lighting up LED 3, that in
this case will be GREEN; if the receiver has been configure ifferently (shut own on restart with or without EDM),
observe instea LED 2, that in this case will be YELLOW, in icating the state of LIGHT, but outputs OFF; YELLOW LED 2
will be blinking in case of MASTER on LIGHT connecte to slaves on DARK. Some mo els with exten e range, or with
a resolution of 14mm, have a LED 4 which can take the colour blue, if that happens with LED 5 RED, it in icates signal
just below the threshol , if it happens with LED 5 GREEN, it in icates signal just above the threshol , see also Tab.: 6,
Chap.: 8. To simplify any receiver will be on light if LED 3(or 5) is GREEN or LED 2(or 4) is YELLOW on stea y or
blinking.
3) Now try a justing the receiver aroun the original position an efine a zone in which the receiver is in the LIGHT.
More careful alignment than as obtaine normally coul be ensure by temporarily arkening the optics of the receiver
with opaque a hesive tape precisely covering half of the optical win ow an then seeking the con ition of light un er
these con itions; on obtaining the con ition of LIGHT, on removing the tape the signal will be at least with margin 2.
Now check that with mo erate mechanical stresses applie to the safety light curtain it remains in the LIGHT. Now
procee with step 5).
4) If you are not able to bring the receiver into the light or to ensure an a equate level of margin, correct the position
of the emitter an try to align the receiver again, step 3).
5) Again temporarily lock the receiver in the mi le of the foun zone an check it has an acceptable arrangement. If it
is acceptable procee with step 6), if it is not acceptable correct the alignment of the emitter accor ingly an realign
the receiver, step 3).
6) After alignment, permanently lock the safety light curtain an restore all the require con itions for the application,
inclu ing the electric connections.
) Have complete functional testing carrie out on the safety light curtain, inclu ing a resolution test an checking for
the presence of reflective surfaces, using a test ro , of the same iameter as the rate resolution.
8) Make sure that uring normal use no unfavourable con itions arise aroun , such as:
- presence of other emitters or other bright or mo ulate sources of light able to hit the receiver,
- presence or movement of reflective objects near the area,
- transparent or semi-transparent materials inserte in the path of the beams,
- systematic presence of ust or spray of liqui s able to foul the surface of the optics.
Indication
Correct optical alignment with goo excess gain enables avoi ing instability in the behaviour of the
safety light
curtain, re ucing optical interference, reflections from shiny surfaces an in general ensuring greater safety.
Danger!
Remember to restore the wiring an check the require metho s of operation of the application again.

6.3 Electrical installation.
Before procee ing carefully rea the ata of Tab.:1; Chap.:7 in the sections: Supply, Outputs an Connections.
See Tab.: 1-4 in this chapter to make the require connections for the supply, loa an configuration for the
connectors. Preferably use prewire connectors; for the Master/Slave connections use only extensions.
Use PELV power supplies, in accor ance with Chap.6.4. of EN 60204-1.
If using a non-stabilize power supply, the transformer must have ouble insulation an a equate power, the
secon ary win ing must be 18V, bri ge power factor correction, capacity C with a minimum value of 2200µF for
absorptions up to 1A, for higher absorptions a 2200µF for every extra Ampere.
Connect the supply cables irectly to the source an not ownstream of other power or highly in uctive evices.
Run the cables of the safety light curtain in e icate raceways or, where only signals run, o not use raceways that
carry power cables.
Make sure the functional earth cable (FE) is connecte irectly to the general groun terminal.
Before inserting the connector, check that the mains voltage an the supply voltage are within the require limits, apply
the connector an check again that the supply voltage has a correct nominal value an remains within the limits efine
in all the working con itions, check the limits in the two extreme con itions of minimum an maximum absorption of all
of the evices connecte to the same power supply, especially if this is not a stabilize power supply.
