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 control systems or parts of control systems for machine installations. EKS can be used, for
example, as part of an overall system for checking access rights on the selection of the operating mode.
However, it is not permitted to derive the operating mode directly 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.
Information!
The Machinery Directive 2006/42/EC provides information on selection of the operating mode. It is
imperative that this information be followed.
When designing machines and using the Electronic-Key adapter, the national and international regulations and
standards specific to the application must be observed, e.g.:
EN 60204, Safety of machinery –Electrical equipment of machines

terminology, methodology
EN 62061, Safety of machinery –Functional safety of safety-related electrical, electronic and programmable
electronic control systems
EN ISO 13849-1, Safety of machinery –Safety-related parts of control systems –Part 1: General principles
for design
Modifications to the electronics of the Electronic-Key adapter and any other changes, especially mechanical
modifications and reworking, are not permissible and will result in the loss of the warranty and exclusion of
liability.

3 Function
3.1 Functional description
3.1.1 Common functions of EKS Standard and version EKS FSA
The EKS is used for access control and monitoring on control systems or parts of control systems for machine
installations.
Instead of passwords, coded Electronic-Keys are assigned. In this way unauthorized access to control and
visualization systems is prevented to the greatest possible extent.
The EKS uses a non-contact, inductive read/write identification system.
It comprises:
Electronic-Key
Electronic-Key adapter
The user is responsible for organizing the programming of the application, integration into an overall system and
the assignment and use of the freely programmable memory in the Electronic-Key.
Information!
For easier organization and management of your Electronic-Keys and the data they contain, EUCHNER
also offers the Electronic-Key-Manager EKM software. To enter data in the EKM software, an
Electronic-Key adapter with serial interface or USB interface must be in operation on the PC.
EKS Ethernet TCP/IP devices are read/write systems with electronics for the inductive bidirectional interface to
the transponder and interface electronics.
Due to the non-contact transfer of data, the Electronic-Key adapter is designed with a high degree of protection
suitable for industry from the access side. The Electronic-Key adapter is fastened from the rear side of the panel
in order to exclude unauthorized tampering from the operator side.
The system is connected via the integrated Ethernet TCP/IP interface, which is designed as an RJ45 socket. A
separate switch may be required for the Ethernet TCP/IP connection. The device does not have an integrated
switch.
Setup and system integration can be implemented straightforwardly and quickly on the Electronic-Key adapter
with Ethernet TCP/IP interface.
The current state of the Electronic-Key adapter is displayed using a 3-color LED.
For operation, the Electronic-Key is inserted into the Electronic-Key adapter and is held in place by a spring clip.
The power supply for the transponder and the data are transferred between the Electronic-Key adapter and the
Electronic-Key without using any contacts.
Figure 1: Cut-away illustration of Electronic-Key adapter
The Electronic-Keys are tag shaped. The complete transponder with memory chip and antenna is integrated
into the Electronic-Key. The transponder does not have a battery.

Page 10/34 Subject to technical modifications 2100420-03-05/19
The data carrier in the Electronic-Key is equipped with a combined memory:
116 bytes E2PROM (programmable) plus 8 bytes ROM (serial number)
The programmable memory of 116 bytes is organized in 4-byte blocks. This means a multiple of 4-byte-sized
blocks must always be written.
3.1.2 Additional functions of the version EKS FSA
The version EKS FSA has two additional switching contacts (semiconductor relay) LA1/LA2 and optionally
LB1/LB2 that are switched off as long as there is no Electronic-Key in the Electronic-Key adapter or if it is not
possible to read the Electronic-Key.
The switching contacts are electrically isolated from the device electronics and from each other. Either AC or
DC can be switched.
Each of the contacts is operated with diversity by a dedicated processor that opens the contacts on removal of
the Electronic-Key (see figure Block diagram EKS FSA).
Figure 2: Block diagram EKS FSA
Due to separate evaluation of channel LA and channel LB, the EKS FSA device can be used in conjunction with
a safe evaluation device in safety-related applications. Integrated voltage monitoring switches off the switching
contacts LA and LB if the power supply is outside the permitted tolerance (see chapter 4.2).
Information!
The switching contacts FSA close when the Electronic-Key is in place, irrespective of the data allocation
in the memory.
