3.4 ELECTRONIC MONITORING AND CONTROL SYSTEM ECS
Explanation of the statistics print-out
You receive for example the following print-out:
Column
Column 1:
Good: Time with no faults, number of faults = 0
Err : Time, where faults have occurred, number of faults = 7
The numbers 524, 578, etc. indicate the message page number in
the text store.
Column 2:
The number indicates, how often the fault has occurred, for exam-
ple the fault of page no. 590 has occurred 3 times. In line "Err"
(Error) the number of faults is summed up, the result is 7.
Column 3:
Here is indicated in percent, how often the fault has occurred
applying to the total number of faults (7 = 100 %).
Column 4:
The time indicates, how long the fault has been present. If a fault
has occurred more than one time, the sum of time will be indi-
cated here.
Column 5:
The duration of the fault applying to the total time with faults (Err),
= 4:00:00 (4 hours). This number results in the temporal overlap-
ping of the faults. If you sum up the times, you receive 5:30:00.
Good and Err apply to the sum of Good and Err, respectively.
