1. Statutory provisions
1.1 Conformity to the European
Directives
The EC type examination certificate granted by the
Berufsgenossenschaft E+MIII guarantees the conformity
of the product with respect to the essential requirements
of the following EC Directives:
• Machine Directive 98/37/EC
• Low Voltage Directive 73/23/EC
• Electromagnetic Compatibility Directive 89/336/EC
An EC declaration of conformity is enclosed in this
product installation manual.
1.2 Use
Conditions of use
This installation manual has the following sections:
• Photoelectric safety barriers may be used as
principle protection for presses, punches or
machines where the movement of the functional
parts can be interrupted at any moment in a
dangerous phase.
• Photoelectric safety barriers can only be used as
principal protection on presses or machines on which
the control circuit has been designed in such a
manner that a fault in one component does not result
in any risk.
• Photoelectric safety barriers cannot be used as
principle protection for presses operating
continuously or automatically.
• Photoelectric barriers are protective devices that
output stop signals, not control signals.
• Cancellation of the photoelectric safety barrier stop
signal must not cause the re-start of moving parts. A
restart may only be initiated by means of a control
designed for this purpose.
Additional protection
In some applications, it may be necessary to provide
additional protection to that of the safety barrier. Material
screens or more safety barriers can be used, in such a
way that the operator is obliged to pass through the
detection field in order to enter the danger zone, and is
not able to stay between the danger zone and the safety
barrier.
Additional protection must be placed and be of such
dimensions that it will not permit an operator to reach the
danger zone via the top, the bottom, the rear and
laterally.
Additional protection devices will have to be:
• fixed (fitted with the aid of a tool, or welded if
possible) ;
• or automatically positioned and checked, if their
opening is necessary.
It must not be possible for operators to neutralize the
detectors associated with these additional protection
devices.
1.3 Installation
The installation of a photoelectric safety barrier is subject
to very strict rules which may vary from country to
country.
Correct installation is necessary to ensure safety and
must be carried out according to European regulations.
EN 292 ”Safety of Machinery - Basic
concepts, general principles for
design”
EN 60204 ”Safety of Machinery - Electrical
equipment of machines”
IEC 61496-1/2 ”Safety of Machinery - Electro-
sensitive Protective Equipments”
EN 999 ”Safety of machinery - The
positioning of protective equipment
in respect of approach speeds of
parts of the human body“
EN 294 ”Safety of machinery - Safety
distances to prevent danger zones
being reached by the upper limbs”
EN 811 ”Safety of machinery - Safety
distances to prevent danger zones
being reached by the lower limbs”
In the absence of existing harmonized standards, the
following local regulations may apply:
U.K.: PM41
Germany: DIN 31001
France: NFE 09010
1.4 Important remarks on safety
The photoelectric barrier is only one part of an integrated
safety system. A complete safety system can be
compared to a chain, where correct functioning of each
link is essential for overall security. And as the safety
barrier only forms one link, the rest of the system is of the
user's or machine manufacturer's responsibility.
Especially with regard to the stop relay, only use fail to
safe schemes (if necessary, please consult the safety
authorities of your country).
