The monitoring function of the PNOZ s30 can be used to implement safety functions
defined in the standard EN 61800-5-2 for Adjustable speed electrical power drive systems.
Safety functions in accordance with
EN 61800-5-2
Implementation with PNOZ s30 safety func-
tion

Safety-related architecture
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)
1* Manufacturer-
specific
0 % Monitoring
1 encoder
2,34-08
*In accordance with EN ISO 13849-1, Category 1 is only met if the sensor is a "well-tried
component".
