Channel B
– shut-down via STO/inverter:
Component
MTTFD [years]
DC
Door closer
B10d = 100000
Nop = 30/AT = 10000/year(309 AT/year)
DCSwitch = 99%
SIN/COS
encoder:
MTTFD_SinCos = 30 years
DCEncoder = 99%
PES
PFH = 1.4 * 10-8
DCPES = 99%
STO/ inverter
MTTFD_STO = 150 years
DCPES = 90%
Resulting PI for both channels:
Symmetry of both
channels:
DC mean value
Pl
MTTFD_STO = 27 years = average
DC avg = 98 % = average
P =“ “ ( o EN ISO 13849-1, tables 5, 6 and 7)
In this case the B10d value of the door monitoring feature is is determining
for PI. If an even higher safety level is to be reached a correspondingly
higher qualitative switch is to be used.
Note:
The PI can also be determined with the program tool "Sistema" from BGIA.
