requirements, a power supply for use in class 2 circuits must be used.
110845-04-03/12 Subject to technical modifications Page 5/40
Manual EKS Light and Light FSA
1.4 Correct use
As part of a higher-level overall system, the EKS read station is used for access control and monitoring on
control systems or parts of control systems (e.g. of machines). The 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.
Outputs A, B, C, D and strobe plus the switching contact LA1/LA2 switch only if there is an authorized
Electronic-Key in the read station. Outputs A, B, C, D and strobe (channel LB) plus the switching contact
LA1/LA2 (channel LA) must be polled by a safe downstream evaluation to suit the risk determined. The outputs
A, B, C, D and strobe (channel LB) are used to supply the information as to whether the or not an ElectronicKey is inserted and which access rights are assigned to the Electronic-Key. The output LA1/LA2 (channel LA) is
used for the redundant supply of the information as to whether or not an authorized Electronic-Key is inserted
(independent of the access rights).
The control system must check whether the Electronic-Key placed is authorized to select the operating
mode and whether the access rights on the Electronic-Key permit operation in the operating mode currently
selected.
The user must select the related operating mode using the control system or another suitable circuit.
The manufacturer of the system must check which safety level is reached with the overall system and
whether the overall system provides adequate safety against hazards in the intended application.
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 read station, 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 read station 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 read station must only be employed and used in accordance with
this manual and
other documentation referred to in this manual.
The EKS read station is not a safety component in the sense of the machinery directive.
Without additional precautions the EKS read station must not be used to provide a safety function, particularly if
failure or malfunction of the unit could endanger the safety or health of people in the operating area of a
machine.
For applications in which the machinery directive is not applicable (vehicle manufacturing, building services
engineering or similar), the applicable regulations and standards from the respective field must be taken into
account.

3 Function
3.1 Functional Description
3.1.1 Functions of EKS Light
EKS Light is used on control systems or parts of control systems for access control and monitoring.
Instead of passwords, coded Electronic-Keys are assigned. In this way, unauthorized system access (e.g. to
control and visualization systems) is prevented to the greatest possible extent.
EKS Light uses a non-contact, inductive read identification system.
It consists at least of:
Electronic-Key
Electronic-Key adapter EKS Light compact or Electronic-Key adapter FHM with interface adapter EKS Light
modular
For configuration, you will require at least the following items:
A commercially available Windows
EKS Electronic-Key adapter with USB interface or serial interface
®
PC
Electronic-Key-Manager EKM Light software
Programming of the application and the integration into an overall system are organized by the user.
EKS Light is characterized by simple integration into the control system environment. After the Electronic-Key is
placed, the Electronic-Key's data are evaluated within the device as the first step, which permits automatic
Electronic-Key recognition without the aid of the control system. Once the internal check of the data integrity is
complete, an access level is issued at the data outputs.
The EKS Light read station is a read-only system with integrated evaluation electronics and interface. The
access level is output via a 4-bit parallel interface. The parallel interface offers the advantage of transparent
depiction of the data and therefore simple connection directly to the inputs of a control system or a switching
device.
An EKS operating state (OS), an access level (AL), an access code (AC), a checksum (CRC) and a serial
number are stored on the Electronic-Key. When an Electronic-Key is inserted, the data range relevant for the
respective operating state is automatically read from the Electronic-Key into the device, temporarily stored there
and evaluated. If a valid Electronic-Key is detected, the outputs on the read station are set to High depending on
the stored values of the access level. All outputs are reset to Low when the Electronic-Key is withdrawn.
The read station and Electronic-Key are separately parameterized with values which have to match. Parameter
assignment to the Electronic-Key adapter is performed exclusively via the DIP switch.
Figure 1: DIP switch setting and access code on the Electronic-Key.
110845-04-03/12 Subject to technical modifications Page 9/40
Manual EKS Light and Light FSA
Parameter assignment for the Electronic-Keys is performed exclusively via a programming station on the PC.
An EKS Electronic-Key adapter with USB interface (order No. 092 750) or with serial interface (order No. 084
750) is installed on the PC for this purpose. Programming is performed via the Electronic-Key-Manager EKM
software with an input mask suitable for the operating state (see section 8 Parameter assignment of the
Electro
nic-Keys via the Electronic-Key-Manager EKM software)
Due to the no
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 current state of the Electronic-Key adapter is displayed using a 3-color LED.
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.
The Electronic-Key is placed on the Electronic-Key adapter for operation. The power supply for the transponder
and the data are transferred contactlessly between the Electronic-Key adapter and Electronic-Key.

Manual EKS Light and Light FSA
3.1.2 Additional functions of the version EKS FSA
The EKS FSA version features an additional semiconductor switching contact (LA1/LA2) that is switched off as
long as there is no authorized Electronic-Key in the Electronic-Key adapter or if the Electronic-Key cannot be
read.
The semiconductor switching contact is galvanically isolated from the device electronics. Either AC or DC can
be switched. Outputs A, B, C, D and strobe on the first channel LB and the semiconductor switching contact on
the second channel LA are each operated with diversity by a dedicated processor that switches off the outputs
or the switching contact on removal of the Electronic-Key (see Figure Block diagram EKS FSA).
Figure 4: Block diagram EKS FSA
By separately evaluating channel LB and channel LA, the EKS FSA device can be used in conjunction with a
safe evaluation device in safety-related applications. Integrated voltage monitoring switches off outputs A, B, C,
D and strobe (channel LB) or the semiconductor switching contact (channel LA) if the power supply is outside
the permitted tolerance (see section 5.2).

4 Operating states
Information!
Various operating states are available, depending on the EKS Light version.
Refer to section 1.1 Use of the manual to check which operating state your devi
The operating state determines the function of the system, which comprises the read station (also referred to as
device below) and Electronic-Key. The operating state defines the scheme according to which automatic
Electronic-Key recognition functions and how an access level is issued.
The operating state is set using DIP switches on the read station. The various operating states are stored in the
device software (firmware). The value for the operating state is also programmed on the Electronic-Key. Values
in the Electronic-Key and in the device must match.
What is the same in all operating states?
Parity bit comparison in the device. The parity bit is used to check the values set within the DIP switch. By
this an accidentally reset or faulty DIP switch can be recognized.
Matching of the EKS Light data block on the Electronic-Key with the set values in the device. This also
includes a comparison of the checksum (CRC). The checksum is stored on the Electronic-Key. After the
Electronic-Key is inserted, the checksum is calculated in the device and compared with the value on the
Electronic-Key. Access is released only if the values agree. The checksum is formed using the programmed
EKS Light data block required for the operating state and the serial number of the Electronic-Key. Like the
serial number, the checksum is therefore also a unique number. The cyclic redundancy check routine
prevents data manipulation outside of the defined software environment.
