Foreseeable misuse
The following foreseeable misuse is among those not approved as intended use:
–
outdoor operation
–
use in non-industrial areas
–
use outside the limits of the product defined in the technical data
–
use with inappropriate function modes
–
unauthorised modifications
NOTICE
The use of connection and interlinking blocks that are not specified is not permissible
Tab. 9 Permissible manifold blocks
Tab. 11 Permissible interlinking blocks.
NOTICE
The use of the input module CPX-F8DE-P for implementation of safety circuits is not permissible in the
following cases:
• in a CPX terminal equipped with CPX-FEC or CPX-CEC
• in a CPX terminal of variant P
• in configurations other than the configurations stated
2.3.3 Details of the function modes.
NOTICE
In the event of damage caused by unauthorised manipulation or use other than the intended use, the
guarantee will be invalidated and the manufacturer will not be liable for damages.
1.6
Achievable safety classification
The CPX-F8DE-P can be used to implement safety functions up to:
–
Performance Level e, Cat. 4, in accordance with EN ISO 13849-1
–
Safety integrity level SIL 3 in accordance with EN 61508
–
Performance Limit SIL CL 3 in accordance with EN 62061.
The achievable safety classification of the overall safety device depends on the set function mode as
well as other components used to implement the safety function.
–
Make sure that the overall safety function of the system is analysed and validated. It is the responsi-
bility of the operator to determine and verify the required safety classification (safety integrity level,
performance level and category) of the system.
–
Be aware of the residual risks that remain in your system despite the measures to integrate safety
in the design, despite safety precautions and despite the supplementary protective measures.
The residual risks are determined, among other things, by your safety regulations and the safety
characteristics of your system.
