RoHS Directive 2011/65/EU. The devices comply with the following European standards:
EN 55011 Industrial, scientific and medical equipment – Radio-frequency disturbance
characteristics – Limits and methods of measurement
EN 61000-6-2 Electromagnetic compatibility (EMC) – Part 6-2: Generic standards – Immunity standard
for industrial environments

1.3 Approvals
The EKS devices with USB interface are certified in accordance with (UL file number E240367).
For use and operation as per the requirements, a power supply with the feature “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 PC-based 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.
Infor
mation!
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
EN 12100-1, Safety of machinery – Basic concepts, general principles for design – Part 1: Basic
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.
The Electronic-Key adapter must be employed and used only in accordance with
this manual and
other documentation referred to in this manual.
The EKS Electronic-Key adapter is not a safety component in the context of the Machinery Directive.
Without additional precautions, the EKS Electronic-Key adapter must not be used to provide a safety function,
particularly if failure or malfunction of the device could endanger the safety or health of people in the operating
area of a machine.
1.5 Obligations on the operating organization
The manufacturer and the organization operating the higher-level overall system, e.g. a machine installation, are
responsible for the observance of national and international safety and accident prevention regulations
applicable in the specific case.

2 Safety precautions
Warning!
The EKS Electronic
-Key adapter is not a safety component in the context of the Machinery Directive.
Without additional precautions, the EKS Electronic
-Key adapter must not be used to provide a safety
function, particularly if failure or mal
function of the device could endanger the safety or health of
persons in the operating area of a machine. On this topic, pay particular attention to the sections
Correct use
(see chapter 1.4) and Electrical connection (see chapter 6).
Warning!
Mounting and electrical connection are allo
wed to be performed only by authorized personnel who are
familiar with the applicable regulati
ons on accident prevention and have read and understood this
manual.
Furthermore, mounting and electrical connection of the version EKS
FSA must be performed only by
personnel familiar with handling safety components.
Caution!
Modifications to the ele
ctronics 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.

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 PC-based 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 Elect
ronic-Key-Manager EKM software.
EKS USB 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 USB interface that is designed as a virtual COM port in Windows®-
based systems. The power supply is also provided via the USB connection.
Setup and system integration can be realized straightforwardly and quickly on the Electronic-Key adapter with
USB interface. Data communication is in accordance with the transfer protocol 3964R.
The current state of the Electronic-Key adapter is displayed using a two-color LED.
The Electronic-Key is inserted into the Electronic-Key adapter in housing G01 and is held securely in place by a
spring clip. With the Front-Hook-Compact (FHC) mini Electronic-Key adapter in housing G30, the Electronic key
is held in front or dropped into place. 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: Cut-away illustration of an Electronic-Key
adapter with Electronic-Key in the compact G01
housing
Figure: Illustration of an Electronic-Key adapter with
Electronic-Key in the compact G30 housing
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.

2094485-05-07/19 Subject to technical modifications Page 9/34
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 version EKS FSA (only in G01 housing)
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 switching 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: 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 4.2.1).
Information!
The switching contacts
FSA close when the Electronic-Key is in place
, irrespective of the data allocation
in the memory.
