1.2 CE conformity
The EKS Electronic-Key adapter with Profibus-DP interface conforms to the EMC directive 2004/108/EC
(89/336/EEC, 92/31/EEC, 93/68/EEC) and the low voltage directive 2006/95/EC (73/23/EEC, 93/68/EEC,
98/79/EC).
The Electronic-Key adapter complies with the following European / international standards:
f EN 61000-6-2
Electromagnetic compatibility (EMC). Generic standards - Immunity for industrial
environments
f EN 55011
Industrial, scientific and medical (ISM) radio-frequency equipment -
f Radio disturbance characteristics - Limits and methods of measurement
1.3 Approvals
The EKS Electronic-Key adapter with Profibus interface is certified to (certificate number 170205 –
E240367).
For use and operation as per the requirements, a power supply for use in class 2 circuits must be used.
1.4 Correct use
As part of a higher-level overall system, the EKS Electronic-Key adapter is used for access control and
monitoring on controllers or parts of controllers for machine installations. EKS can be used, for example, as part
of an overall system for checking access rights for operating mode selection. However, it is not permitted to
directly derive the operating mode from the access rights on the Electronic-Key. If the selection of the operating
mode is relevant for safety, this must not be performed by means of the EKS; instead an additional device must
be used to select the operating mode. This is possible via the graphical user interface on the control system, for
example.
The version EKS FSA has outputs that can be utilized to form a safe shut-down signal (for block diagram see
section 3.1.2). For this purpose a safe evaluation must be included downstream. The EKS FSA can then be
used for safety-related tasks. The machine must be reset to a safe operating mode by removing the Electronic-
Key. A hazard analysis on this aspect must be prepared as per the requirements in the machinery directive.
The risk and the necessary risk minimization by technical means must be determined using a suitable standard.
