All the values in the table are worst case values for one safety function and are fulfilled in any valid configuration.
The values above are calculated with these assumptions:
MTTR = MTR = 0 h. When a failure is detected, the STO safety function becomes active.
The proof test interval is 20 years.

The response time to a violation depends on these factors:
Pulse per rotation (PPR) of the speed measurement sensor. The response time is faster with a higher PPR value.
Actual speed at the time of the violation of the monitored speed limit. The response time is faster in higher speeds.
