Electromagnetic Compatibility - Kendrion Kuhnke Vico 404 User Manual

Kendrion Kuhnke Automation GmbH
 Take particular heed of the hazard warnings
Information
To achieve a high degree of conceptual safety in planning and installing an electronic controller,
it is essential to exactly follow the instructions given in the manual because wrong handling could
lead to rendering measures against dangers ineffective or to creating additional dangers.
Project Planning

24 VDC power supply: generate as electrically safely separated low voltage. Suitable devices
include split-winding transformers built in compliance with European Standard EN 60742
(corresponds to VDE 0551).

Power breakdowns or power fades: the program structure is to ensure that a defined state at restart
excludes all dangerous states.

Emergency-off installations must comply with EN 60204/IEC 204 (VDE 0113). They must be
operative at any time.

Safety and precautions regulations for qualified applications have to be complied with.

Please pay particular attention to the notices of warning which, at relevant places, will make you
aware of possible sources of dangerous mistakes or faults.

Relevant standards and VDE regulations are to be complied with in every case.

Control elements are to be installed in such a way as to exclude unintended operation.

Lay control cables such that interference (inductive or capacitive) is excluded if this interference
could influence controller operation or its functionality.
Maintenance and Servicing

Precautions regulation BGV A3 (Elektrische Anlagen und Betriebsmittel) to be observed when
measuring or checking a controller after power-up. This applies to section 8 (Admissible deviations
when working on parts) in particular.

Spare parts: Only use parts approved of by Kuhnke. Only genuine Kuhnke modules must be used in
modular controllers.

Modular systems: always plug or unplug modules in a power-down state. You may otherwise
damage the modules or (possibly not immediately recognisably!) inhibit their functionality.

Always dispose of (rechargeable) batteries as hazardous waste.

1.3.8 Electromagnetic Compatibility

Definition
Electromagnetic compatibility is the ability of a device to function satisfactorily in its electromagnetic
environment without itself causing any electromagnetic interference that would be intolerable to other
devices in this environment.
Of all known phenomena of electromagnetic noise, only a certain range occurs at the location of a given
device. It is defined in the relevant product standards.
The design and immunity to interference of programmable logic controllers are internationally governed by
standard
IEC 61131-2 which, in Europe, has been the basis for European Standard
EN 61131-2.
