A safety function's SIL/PL values are not identical to the SIL/PL values of the units that are used and may be different. We recommend that you use the PAScal software tool to calculate the safety function's SIL/PL values. Operating Manual PNOZ XV2.1 | 20 20690-EN-08... -

If the service life graphs are not accessible, the stated PFH value can be used irrespective of the switch frequency and the load, as the PFH value already considers the relay's B10d value as well as the failure rates of the other components. Operating Manual PNOZ XV2.1 | 21 20690-EN-08... -
Page 22: Service Life Graph
To increase the service life, sufficient spark suppression must be provided on all output contacts. With capacitive loads, any power surges that occur must be noted. With DC con- tactors, use flywheel diodes for spark suppression. Operating Manual PNOZ XV2.1 | 22 20690-EN-08... -
