2.3 General safety instructions and measures of protection
Safety instructions!
To ensure LS2 safety lig t curtain
s are used to standard and in a safe manner it is necessary to observe t e following
points:
• For t e installation and use of t e LS2 safety lig t curtain
as for commissioning it and t e repeated tec nical tests,
national and international regulations apply, particularly:
– Mac inery directive 2006/42/EC
– t e Directive on work equipment operators 2009/104/EC
– t e accident prevention prescriptions and safety rules
– ot er important safety prescriptions.
• T e manufacturers and operators of t e mac ine on w ic t e LS2 safety lig t curtain
is used must, in agreement wit
t e relevant aut ority and under t eir own responsibility, apply all t e current safety rules and prescriptions and are also
in c arge of t eir observance.
• It is absolutely necessary to observe t e guidelines on c ecking
t ese operating instructions (see c apter 6
“Commissioning”).
• T e c ecks must be carried out by qualified persons, t at is by aut orized and specially appointed persons, and t ey
must be documented so as to be compre ensible at any moment.
• T e operating instructions contained in t is manual must be set at t e disposal of t e operator of t e mac ine used
wit LS2 s.
T e mac ine operator must be educated by qualified personnel and urged to read t e operating instructions.
2.4 Disposal
Dispose o
f unusable or unrepairable devices always in observance of current national prescriptions on t e subject of
waste disposal.
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.
