Declaration
Our internal company quality management system ensures information on safety-related systematic faults which become evident
in the future
1)
Maximum admissible 1 demand per week.
2)
FIT = Failure In Time, number of failures per 10
9
h
3)
Valid for average ambient temperature up to +40 °C (+104 °F)
For continuous operation at ambient temperature close to +60 °C (+140 °F), a factor of 1.5 should be applied
4)
PTC = Proof Test Coverage
5)
All diagnostic functions are performed at least once within the diagnostic test interval
6)
Maximum time between error recognition and error response
