9.2.1.1 MTTF >= 10 years
MTTF >= 10 years 9- SI_Kennzahlen_protego S1_ein_Geber_MTTF_10
SI_Kennzahlen_protego S_ein_Geber_MTTF_10_Einl
This operating mode requires a motor encoder with MTTF ≥ 10 years.
SI_Kennzahlen_protego S_ein_Geber_MTTF_Allg
The motor encoder is already included in the characteristic data, so no
more calculations need to be performed for the "Safe Actuator" subsys-
tem.

SI_Kennzahlen_alle_Sicherheitsfunkt_protego S
The safety-related characteristic data is valid for all safety functions.
Si_Kennzahlen_Erläuterung_1
All the units used within a safety function must be considered when cal-
culating the safety characteristic data.
