Note:
If T1 > 1a is needed in low demand mode of operation, SIL 1 / PL c levels are used
and PFD is calculated separately.

1) PFH values are according to EN ISO 13849.
2) DC for low demand mode is 90% (determined by the DC of the worst component in the subsystem).
3) See the recommendation of use CNB/M/11.050 published by the European co-ordination of notified bodies for lower T1
requirement.
4) T1 = 20a is used with high demand mode of operation. T1 = 1a is used with low demand mode of operation. See also
section Proof test interval.
