1)
PFH values are according to EN ISO 13849.
2)
In low demand mode, DC of electromechanical devices is considered as 0%, and therefore no overall DC value is claimed
in low demand mode.
3)
See the recommendation of use CNB/M/11.050 published by the European co-ordination of notified bodies for lower T
1
requirement.
4)
T
1
= 20a is used with high demand mode of operation. T
1
= 1a is used with low demand mode of operation.
Note: If T
1
> 1a is needed in low demand mode of operation, SIL 1 / PL c levels are used
and PFD is calculated separately.
