2. Correct use
EUCHNER key adapters series CKS-K-AS are operated as a slave on the safety bus AS-Interface Safety at Work
This safety component allows dangerous machine movements to be undertaken as long as a valid key is inserted. A stop
command is triggered if the key is removed during the dangerous machine function.
Before use, a risk assessment must be performed on the machine, e.g. in accordance with:
Ì
EN ISO 13849-1, Safety of machinery. Safety related parts of control systems. General principles for design
Ì
EN ISO 12100, Safety of machinery - General principles for design - Risk assessment and risk reduction
Ì
IEC 62061, Safety of machinery - Functional safety of safety-related electrical, electronic and programmable electronic
control systems.
Correct use includes compliance with the relevant requirements for installation and operation, for example
Ì
EN ISO 13849-1, Safety of machinery. Safety related parts of control systems. General principles for design
Ì
EN 60204-1, Safety of machinery. Electrical equipment of machines. General requirements
The key adapter must be used only in conjunction with the designated CKS keys from EUCHNER. On the use of different
keys, EUCHNER provides no warranty for safe function.

Ì
In the estimation of the PL for the overall system, a maximum value of 100 years can be assumed
for the MTTF
