EMC Characteristics of the CL200

Taken as a whole, a process plant must meet certain minimum requirements
with regard to interference resistance. Compliance with the relevant stipula-
tions is contingent upon the process plant engineering company and/or the
vendor of the machine system. Such are the facts as prescribed by the EMC
Statute that is based on the EMC Directive formulated by the Council of the
European Communities.
The minimum requirements for compliance with the EMC Statute are defi-
ned in the form of standards applying to product families. In cases where
such standards do not exist, generic standards are applied. Conformity with
the corresponding regulations is indicated by affixing the CE Label.
The CE Label signals conformity with all relevant guidelines issued by the
Council of the European Communities. However, it shall not be taken as a
seal of quality, nor does it promise certain properties. Instead, its sole pur-
pose is to address the governing authorities.
Depending on the product and area of application, several guidelines or Di-
rectives may be of relevance. In addition, the manufacturer is required to
produce an appropriate Declaration of Conformity which, in the case of an
inspection by the governing authority, must be made accessible to its repre-
sentatives.
In standard practice, conformity is most commonly proven with the use of
standard tests described in the so-called generic standards, e.g., in
EN 61000-4-X = VDE 0847-4-X. However, to ensure interference resistance
also in the field, the user himself must adhere to the installation prerequisites
and instructions supplied by the manufacturer.
More often than not, when planning and constructing a process plant and/or
machine system, the EMC Directive is augmented by the Low–voltage Di-
rective, EU Declaration of Conformity, and quite possibly a number of guide-
lines referring to specific types of system installations.
As a standalone unit, the CL200 already meets the EMC requirements ari-
sing from the governing standards.
Compliance with these standards was tested on specific system configura-
tions. However, this fact shall not be construed to mean that such testing ser-
ves to confirm the existence of the required electromagnetic compatibility of
the system for any given configuration. The responsibility for the overall sy-
stem is borne only be the process plant engineering company.
Sufficient electromagnetic compatibility may be achieved only on the basis
of meticulous adherence to installation guidelines. Only when this prerequi-
site has been met, it may be safe to assume that a system composed of indi-
vidual devices bearing the CE Label also complies, as an entity, with the
protection objectives embodied in the Directive issued by the Council of the
European Communities.
