Note on fault frequency of operating time - AD91.60-P-2000-13GH
Diagnosis - Fault frequency, operating time
A fault time with start and finish fault time is assigned to each fault
Fault frequency 4
The operating time which has elapsed since the first occurrence of this fault is 6 h 15 min.
The operating time which has elapsed since the last time this fault disappeared is 4 h 35 min.
Example:
- Fault frequency: Fault occurred 4 times
- Period of time which has elapsed since the fault occurred: 6 h 15 min.
- Period of time which has elapsed since the same fault disappeared: 4 h 35 min.
Fault frequency (number)
Operating time (h, min., s) 0 No fault found
BFU=Fault time starts 1, 2, 3, 4 fault found (occurred 4 times, did not occur 4 times)
EFU=Fault time stops
