4.5.5 Error Monitoring
Valid for all systems
Currently 10 single error bits are set on the board which can be summarized to an entire er-
ror message by means of the error priority input.
The setting of a failure bit is delayed approximately 4 minutes in order to blank out sporadic
failures. However, this does not mean that for the internal signal processing sporadic failures
are also blanked out for 4 minutes.
A logical '1' indicates that there is a failure.
Underneath the failure message it is shown how the failure influences the total failure mes-
sage.
Selection frame:
ERROR MONITORING Y/N
Display frame:
ERROR-NO 1-8 >00000000< 9-16 >00000000<
PRIORITY 1-8 >H--L---H< 9-16 >LL------<
The various failure bits have the following meaning:
ERROR-1
0 / 1
ERROR-2
0 / 1
ERROR-3
0/1
36 / 44
