To calculate the safety function you will need the following data for the "sensor" subsystem
and "PNOZ s30" subsystem:
Sensor PNOZ s30 subsystem
Category MTTFd DC Operating mode PFH (1/h)
4 Manufacturer-
specific
90 % Monitoring
2 encoders
1,44E-09
In a worst case scenario, the sensor subsystem's characteristic value MTTFd is calculated
from the inferior (lower) value of the two sensors.
