►
Check whether the configured safety application monitors the machine or plant
as intended and if the safety of the configured application is maintained at all
times. This must be ensured in every operating mode and secondary application.
Document the results of this thorough check.
►
Check the safety function again after any change to the configuration.
►
Observe the testing information in the operating instructions for the connected
