3.0 DESCRIPTION OF THE PRODUCT
3.1 Brief description
T e LS2 series curtains are multiple lig t beam safety devices, built in compliance wit t e IEC 61496-1 and 2
standards, are Type 2 and t erefore applicable for t e protection of t e operators of systems or dangerous mac ines.
According to t e requirements of t e EN 61496-1 standard, a Type-2 safety lig t curtain must be able to carry out
periodical testing on its internal circuits to detect t e presence of any dangerous faults.
LS2 safety lig t curtains ave a slim profile of 28x30mm, t e distance of 28mm refers to t e front side, t ey ave a
rear groove for fastening, t ey are extremely reliable devices, t e Receivers provide two protected static safety PNP
outputs, so t ey are not subject to output contact wear or affected by strong vibration, t ey are able to detect
internal faults, control external contacts and, in t e event of a fault, ensure safe be aviour in any case. Wit a free
area t e level of t e two outputs is enabled to be ig (status ON, outgoing current), wit an occupied area or in case
of fault t e level is low (status OFF).
T e Emitters ave a Test input, t at can be used if it is necessary to control t e devices downstream from t e
Receiver.
T ere are models wit different resolutions (smaller diameter of t e detectable object) dedicated to certain detection of
ands, limbs and body; t e different resolution for models of t e same type enables c oosing different safety
distances.
Safety lig t curtains are available wit resolutions of 30, 40, 50, 90 mm, eig ts from 160 to 1510mm, maximum
ranges of 3, 4, 10, 12m. Multi-beam safety lig t greed are available wit 2, 3, 4 beams dedicated to access control.
T e Base and standard models can be used individually, t e Master, Slave and Final slave models can be used in
a c ain of two or t ree elements, also wit different types of optics; t is enables creating complex applications in a
simple cost-effective manner, for ig ly integrated protected zones even wit different resolution or range
requirements.
T e Base models ave only t e automatic restart function wit out controlling t e external contacts (EDM).
On t e standard and Master models it is possible to combine all t e functions by wiring as preferred: external
contact control (EDM), automatic starting, manual starting.
All t e models use M12 connectors with 5 or 8 poles, for t e supply/output cables and t e interconnection cables
in a c ain no s ielding is required, t e output cable can reac lengt s of 100m, t e interconnection cable 50m, t ese
features also allow great operational flexibility.
T e required operational voltage is 24V
DC
±20%, t e absorbed power is moderate, at most 3W per pair; t e
maximum output current is 400mA, suited to drive even power contactors directly; t e restart interlock and EDM
function, present on t e standard and Master models, enable making versatile and integrated protection systems.
Normally, t e degree of protection of t e ousing is IP65+IP6 , suitable also for dusty environments or compatible
wit p enomena of condensation, except for t e front surface t at as strict optical requirements.
Models are available wit IP69K protection t at can be subjected to was ing wit jets of ot water up to 80°C and
pressure up to 80 bar; wit t is level of protection models are also available wit an integrated t ermal auto-control
system t at moreover enables working at temperatures as low as -25°C and avoiding condensation on t e optics.

4.0 INSTRUCTIONS FOR POSITIONING THE SAFETY LIGHT CURTAINS
4.1 Respecting the safety distance
A safety distance must be maintained between t e protection surface composed of t e beams of t e optico-
electronic
safety lig t curtain and t e point of danger.
T is distance must ensure t at, considering a maximum approac speed defined by t e standard, t e point of danger
can only be reac ed w en sufficient time as elapsed so t at t e dangerous state of t e mac ine as ended.
The safety distance in accordance with EN ISO 13855 depends:
-
in direct proportion on t e total time for stopping t e mac ine or system, w ic corresponds to t e sum of t e
individual times
of reaction of t e w ole safety c ain (t e individual response times are indicated in t e tec nical
documentation of t e safety devices and of t e mac ine itself or must be verified wit specific measures).
- in direct proportion on t e approac speed.
- in direct proportion on t e resolution of t e safety lig t curtain
, or inversely to t e number of beams for t e unit of
eig t.
If t e mac ine is subject to a specific standard of type C, t e indications of t is standard must be followed.
Danger of f
ailed recognition!
Particularly in access protection applications, people may stop in t e danger area, but not in t e optical
beam between t e Emitter and t e Receiver, and t eir presence mig t not be recognized.
Make sure t at dangerous states can only occur w en t ere are no persons in t e danger area.
Make sure t at t e system restart control is effected from a point providing full visibility of t e danger
area and t at t is control cannot be reac ed from wit in said area.
No protection function
is secure if the safety distance is not correct!
It is indispensable to mount t e safety lig t curtains at t e correct safety distance to ensure t e function
of protection.
If there is a C
-
type standard for the application you are creating, follow
its instructions!
T e following instructions apply only to an industrial environment, t at is to say w ere only adults of
normal constitution are expected 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 t e general procedures for calculating t e minimum safety distance S
, t ese instructions must be followed
if t ere is not a specific standard of type C for t e mac ine to make safe.
Depending on t e application it is necessary to use different calculation sc emes.
In general t e formula as t is form:
S = K * T+ C
W ere…
S = [mm] Safety distance
K = [mm/s] Approac speed, a speed of 2000mm/s is indicated for t e upper limbs and 1600 for t e lower limbs.
T = [s] Total stopping time: response time of t e entire safety device + mac ine stopping time.
C = [mm]
Safety distance supplement, to ensure t at t e dangerous zone cannot be reac ed by climbing over t e
beams or inserting limbs between t e beams. It is provided by t e standard, it
takes on a fixed value or is calculated
according to t e optical features of t e safety lig t curtain and its utilization in t e 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 lig t curtain and surface of 90° ±5°
2) PERPENDICULAR APPROACH
Safety light grid in vertical position.
Angle between safety lig t curtain and surface of 90° ±5°
3) HORIZONTAL APPROACH
Safety light curtain in horizontal position.
Angle between safety lig t curtain and surface of 0° ±5°
4) OBLIQUE APPROACH
Safety light curtain in angled position.
Two cases are considered for different angle values α

5.0 MINIMUM DISTANCE FROM REFLECTING SURFACES
T e optical beams of t e Emitter
, aving a beam angle t at is not null, can partly be diverted by reflective surfaces
located near to t e curtains. T is may mean t at a break in t e direct pat of t e optical beam is not d
etected, w ic is
w y all reflective surfaces and reflective objects (in any position t ey may ave wit respect to t e controlled area,
above, under, inside or outside) must respect a minimum distance from t e direct pat of t e beams of t e
safety lig t
curtain.
Indication
It is likewise important to respect t e minimum distance between t e Emitter and Receiver
indicated by
t e manufacturer, in some cases t e minimum distance may be greater t an zero, especially for long-
range models.
At smaller
minimum distances t an t e ones stated, t e beam angle may ave an unpredictable breadt
and so t e safety distance may not be definable wit certainty.
W en using diverter mirrors, consider t at t e minimum distance from reflective surfaces must be
respec
ted for all t e rectilinear segments of t e beams, considering t e sides bot inside and outside t e
protected zone.
A reflective surface is any s iny surface, even a black one.
Any damage or opacification of t e optics or inclusion of slabs of transparent
or, even worse,
semitransparent material on t e optical pat can produce an increase in t e beam angle.
C ecking t e capacity of detection wit t e test rod, performed in t e intermediate
and at t e ends of t e
controlled area, is an effective procedure t
o exclude t e presence of dangerous reflections, see also
C ap.:13.4.
5.1 How to calculate the minimum distance from reflective surfaces
T e safety lig t curtains LS2 respect t e maximum beam angle defined by IEC / EN 61496-2 for Type 2 (a/2=±5°),
or
less.
T e safety distance D is calculated considering t e entire beam angle a=10° and t e safety lig t curtain
s reciprocally
orientated towards t e reflective surface by an angle a
, in t is way we consider t e case of alignment at t e limit of
reciprocal visibility between t e Emitter and Receiver, but w ic is more dangerous due to t e effects of t e reflection.
T e safety distance D to take P ≥3m is calculated as follows:
D=tan(10°)*P/2 = 0.1 63*P/2
For ranges less t an 3m t e value calculated at 3m applies:
D = 0.1 63*1.5=0.264m
Fig.:1; Chap.:5; t is figure s ows t e worst borderline case t at can occur: safety lig t curtains not perfectly aligned,
but tilted by an angle a/2 towards a reflective surface .

6.0 COMMISSIONING
6.1 Mechanical mounting
T is device is suited to work in protected environments, not outdoors.
It is extremely important to secure t e safety lig t curtains to a rigid structure, not subject to deformation or strong
vibration.
C oose t e position of t e Receiver so as not to subject it to strong sources of natural or artificial lig t or to luminous
interference by ot er sensors.
Mount t e Emitter and Receiver facing eac ot er, at t e same eig t off t e reference surface and wit t e same
orientation (refer to t e BASE side t at is t e display side), t e reciprocal distance must be wit in t e field of t e
specification. To secure t e safety lig t curtains to a support use t e specific inserts to apply to t e rear groove and t e
brackets normally provided.
If t ere is vibration in t e application, but still compatible wit t e optical alignment, use t e damping supports
available as accessories.
In t is p ase classic tools suc as a plumb line and/or a spirit level may be useful.
To facilitate t e first p ase of alignment, it is possible to use t e specific LASER STL 01 S accessory for safety lig t
curtains wit a profile of 28x30mm.
Temporarily block t e Emitter and Receiver so t ey are aligned wit and parallel to eac ot er.
Danger!
To perform t e next steps it is necessary to power t e Emitter and Receiver, make sure t at during t is
p ase t e mac ine's movements are blocked irrespective of t e state t at t e Receiver will take on; an
effective manner to obtain t is is to p ysically cut off t e supply to t e actuators by permanently
disconnecting t eir supply cables.
6.2 Alignment
1) W en switc ing on t e LED 1 of t e Emitter will be RED for t e duration of t e power-on, if afterwards t e LED
makes two s ort GREEN flas es t e Hig range function is active, if t e LED makes 2/3 RED flas es, t e TEST is
probably open and t ere is no emission (jumper TEST to proceed), if t e LED is illuminated GREEN it means t at t e
Emitter is working. In case of difficulty wit alignment it is advisable to temporarily activate t e Hig range function, if
it is not already enabled, so as to facilitate it. Refer to C ap.: 6.3 to verify t e Emitter and Receiver configuration mode
and to C ap.:8 for t e meaning of t e indications.
2) If it is possible to c oose or temporarily c ange t e configuration of t e Receiver, it is advised to use t e “Automatic
Restart wit out EDM” mode, t at is able to clearly signal t e state of LIGHT and outputs ON lig ting up LED 3, t at in
t is case will be GREEN; if t e Receiver as been configured differently (restart interlock wit or wit out EDM), observe
instead LED 2, t at in t is case will be YELLOW, indicating t e state of LIGHT, but outputs OFF; YELLOW LED 2 will be
blinking in case of MASTER on LIGHT connected to slaves on DARK.
To simplify any Receiver will be on light if LED 3 is GREEN or LED 2 is YELLOW on steady or blinking.
3) Now try adjusting t e Receiver around t e original position and define a zone in w ic t e Receiver is in t e LIGHT.
More careful alignment t an as obtained normally could be ensured by temporarily darkening t e optics of t e Receiver
wit opaque ad esive tape precisely covering alf of t e optical window and t en seeking t e condition of lig t under
t ese conditions; on obtaining t e condition of LIGHT, on removing t e tape t e signal will be at least wit margin 2.
Now c eck t at wit moderate mec anical stresses applied to t e safety lig t curtain it remains in t e LIGHT. Now
proceed wit step 5).
4) If you are not able to bring t e Receiver into t e lig t or to ensure an adequate level of margin, correct t e position
of t e Emitter and try to align t e Receiver again, step 3).
5) Again temporarily lock t e Receiver in t e intermediate of t e found zone and c eck it as an acceptable
arrangement. If it is acceptable proceed wit step 6), if it is not acceptable correct t e alignment of t e Emitter
accordingly and realign t e Receiver, step 3).
6) After alignment, permanently lock t e safety lig t curtains and restore all t e required conditions for t e application,
including t e electric connections.
) Have complete functional testing carried out on t e safety lig t curtain, including a resolution test and c ecking for
t e presence of reflective surfaces, using a test rod, of t e same diameter as t e rated resolution.
8) Make sure t at during normal use no unfavourable conditions arise around, suc as:
- presence of ot er Emitters or ot er brig t or modulated sources of lig t able to it t e Receiver,
- presence or movement of reflective objects near t e area,
- transparent or semi-transparent materials inserted in t e pat of t e beams,
- systematic presence of dust or spray of liquids able to foul t e surface of t e optics.
Indication
Correct optical alignment wit good excess gain enables avoiding instability in t e be aviour of t e
safety
lig t curtain
, reducing optical interference, reflections from s iny surfaces and in general ensuring greater
safety.
Danger!
Remember to restore t e wiring and c eck t e required met ods of operation of t e application again.
