2. Correct use
Key adapters of series CKS2-K-BP/BR-CC-FLX are used to read and safely evaluate CKS2 keys. The keys have a high coding
level according to ENISO14119. Only the keys listed in Table 1: System components may be used.
Among other applications, they can be used as part of a trapped key system according to ISO/TS 19837.
Table 1: System components
Key adapter 1 key per packaging unit Several keys per packaging unit, with identical key
code and different key identication
CKS2-K-BP-CC-FLX-…
CKS2-K-BR-CC-FLX-… A-FLX-K-0A-RD-168921 A-FLX-K-0B-…
Before the device is used, a risk assessment must be performed on the machine, e.g. in accordance with the following
standards:
ÌENISO13849-1
ÌENISO12100
ÌIEC62061
ÌEN ISO 14119
Correct use includes observing the relevant requirements for installation and operation, particularly based on the following
standards:
ÌENISO13849-1
ÌEN60204-1
The key adapter must be used only in conjunction with the designated CKS2 keys from EUCHNER. On the impermissible
use of different keys, EUCHNER provides no warranty for safe function.
The communication data that can be read via IO-Link must not be used for safety functions.
The user is responsible for the safe overall function, especially for the safe integration into an overall system.
Connection of several devices in a BR series connection is permitted only using devices suitable for this purpose. Check
this in the specications of the device in question.
Important!
ÌThe user is responsible for the proper integration of the device into a safe overall system. For this
purpose, the overall system must be validated, e.g. in accordance with ENISO13849-2.
ÌIt is only allowed to use components that are permissible in accordance with the Table 1: System
components.

3. Description of the safety function
The safety function is dened by the related application.
ÌDevice safety function:
- Safe detection of a key belonging to the system and checking the associated key code. The safety outputs are switched on
if the key is valid.
- The following additionally applies in a BR series connection: the safety outputs are switched only when the device receives
a corresponding signal from its predecessor in the chain.
ÌSafety characteristics: category, Performance Level, PFHD(see chapter 15. Technical data on page 34).
NOTICE
You can regard the complete BR device chain as one subsystem during calculation. The following
calculation method applies to the PFHDvalue:
#1
PFHd,1 PFHd,ext
BR-Device #1 ... n External Evaluation
(e.g. PLC)
PFHdges =∑ PFHd,k + PFHd,ext
n
k=1
#2
PFHd,2
#n
PFHd,n
Alternatively, the simplied method according to section 6.3 of EN 13849-1:2015 can be used for
calculation.
4. Exclusion of liability and warranty
In case of failure to comply with the conditions for correct use stated above, or if the safety regulations are not followed,
or if any servicing is not performed as required, liability will be excluded and the warranty void.
5. General safety precautions
Safety components fulll personnel protection functions. Incorrect installation or tampering can lead to fatal injuries to
personnel.
Check the safe function of the device particularly
Ìafter any setup work
Ìafter the replacement of a system component
Ìafter an extended period without use
Ìafter every fault
Independent of these checks, the safe function of the device should be checked at suitable intervals as part of the mainte-
nance schedule.
DANGER
Danger to life due to selecting the wrong key or tampering.
ÌWhen selecting the key version used, make sure that all measures for risk assessment for the intended
application are performed.
ÌUnused keys must be rendered unusable or protected against unauthorized access to prevent by-
passing the safety function.

DANGER
ÌIf master keys or replacement keys are used, the operating organization must take suitable organi-
zational measures and use a corresponding risk assessment to prevent the system’s safety function
from being bypassed. For this purpose, observe the information in ISO/TS19837.
WARNING
Danger to life due to improper installation or due to bypassing (tampering). Safety components fulll
a personnel protection function.
ÌSafety components must not be bypassed, turned away, removed or otherwise rendered ineffective.
On this topic pay attention in particular to the measures for reducing the possibility of bypassing
according to ENISO14119:2013, section 7.
ÌThe switching operation may be triggered only by keys specially designated for this purpose.
ÌThe key must be completely pulled out of the key adapter in order to switch the safety circuit off safely.
ÌMounting, electrical connection and setup only by authorized personnel possessing the following
knowledge:
- specialist knowledge in handling safety components
- knowledge about the applicable EMC regulations
- knowledge about the applicable regulations on operational safety and accident prevention.
Important!
Prior to use, read the operating instructions and the supplementary documents and keep them in a
safe place. Ensure the operating instructions are always available during mounting, setup and servicing.
For this reason you should archive a printed copy of the operating instructions. You can download the
operating instructions from www.euchner.com.

The key adapter with integrated evaluation electronics forms a safe system together with the corresponding key. The key
determines the function. You will nd further information in chapter 12.1. Conguring the device and teaching-in the key for
the rst time on page 26.
The safety outputs are switched on when there is a valid key in the key adapter. The safety outputs are switched off when
the key is removed.
A key is valid if its key code was allocated to the key adapter in a teach-in operation, see chapter 12. Setup on page 26.
Keys of the version A-FLX-K-0A-RD-168921 are unambiguously allocated to the key adapter in a teach-in operation. With
keys of the version A-FLX-K-0B-RD-…, the taught-in key and all other keys from the same packaging unit are valid after the
teach-in operation because they have the same key code. Only the key version with which the device was congured can
be taught-in. A factory reset must be performed to recongure the device.
Each key is supplied with a unique electronic code. The high coding level ensures a high level of protection against tampering.
The key’s code cannot be reprogrammed.
In case of a fault in the key adapter, the safety outputs are switched off and the LED signals a fault (see chapter 14.3. Error
messages on page 31).
6.1. Monitoring output OD
The device features a monitoring output for the signal OD. Depending on the application, the signal is available at the moni-
toring output or as a status bit. The status bit is evaluated via the BR/IO-Link Gateway. If no BR/IO-Link Gateway is connected,
this output behaves like a monitoring output.
The signal OD is present when a valid key is detected.
6.2. Communication connection C
When the device is connected to a BR/IO-Link Gateway, the monitoring output functions as a communication connection.
The key adapter supplies cyclical and acyclical data. You will nd an overview of the communication data in chapter 11.3.
Overview of the communication data on page 24.

7. Mounting
NOTICE
Risk of damage to equipment and malfunctions as a result of incorrect installation.
ÌTo achieve the degree of protection IP65/IP67, it is necessary to install the key adapter in a clean, at
metal plate at least 2mm thick and to tighten the screws with a tightening torque of 0.25...0.35Nm.
ÌThe device may be damaged if the tightening torque exceeds 0.35Nm.
ÌSuitable strain relief must be provided to prevent damage to the connecting cables.
The key adapter is intended for mounting in control panels with a mounting cut-out measuring 33x68mm according to
DINIEC61554. The device is fastened using screw clamp elements on the rear side of the panel.
Important!
A pushbutton on the rear of the key adapter is used for the teach-in operation, see chapter 12.2.
Teaching-in a new key on page 27. When mounting, ensure that the pushbutton is accessible for
additional teach-in operations after the initial setup.
1. Insert the key adapter, with seal already bonded in place, into the mounting cut-out on the front.
2. Insert the supplied screw clamp elements as far as they will go into the housing cut-outs.
3. Tighten the screws with a tightening torque of 0.25…0.35Nm.
4. After mounting, check the key adapter for rm seating and correct sealing on the front panel.
