Safety note:
The specific safety related characteristic data of the corresponding module can be
taken from the technical characteristic data in chapter 3.
When using several sensors with different functions (e.g. position indicator access door
+ speed detection) for a safety function (e.g. safe reduced speed when access door is
open), these must be assumed as being connected in series for the safety related
assessment of the overall system. See also exemplary calculation in appendix.
The safety regulations and EMC-directives must be strictly followed.
Concerning the applicable fault exclusions please refer to the tables under D in the
appendix of EN 13849-2.
The characteristic data specified in chapter 3 for the partial system PES (e.g. PI e and
PFH-value acc. to table as evidence acc. to EN 13849) can be used for the safety
related assessment of the overall system.
The following examples and their characteristic architecture are mainly responsible for the
assignment to a category acc. to EN ISO 13849-1.
The maximum possible Performance Levels acc. to EN 13849 resulting from this still
depend on the following factors of the external components:
Structure (simple or redundant)
Detection of common cause faults (CCF)
Degree of diagnostic coverage on request (DC
avg
)
Mean time to dangerous failure of a channel (MTTF
d
)
