tiveness of the safety function must be checked by qualified and authorized
personnel.
►
If alterations have been made to the machine or safety function, or if the safety
controller has been changed or repaired, for example by exchanging a module,
check the plant again using the checklist in the appendix.
►
Carry out regular inspections in order to keep the Flexi Soft modules in perfect
working order.
►
Check that the implementation of the Flexi Soft modules complies with all techni‐
cal data.

Check the mounting conditions and check that the Flexi Soft module wiring is
correct.
►
To ensure their reliability, check at regular intervals that the safety functions are
meeting the requirements of the application as well as all applicable regulations
and standards (e.g., regular thorough check).
9.2 Device replacement
Overview
A ser
ious error in one of the Flexi Soft modules impairs the entire network. Therefore
devices that indicate serious errors must be quickly repaired or exchanged. It is recom‐
mended to keep replacement devices for the Flexi Soft modules ready in order to
restore operation as quickly as possible.
