Fault tracing
7.1.1
Identifying hardware errors
1.
Check the module with an error.
•
Check the general IED status in
Main menu/Monitoring/IED status
for
a faulty hardware module.
•
Check the history of changes in internal event list in
Main menu/
Monitoring/Internal events
.
2.
Inspect the IED visually.
•
Inspect the IED visually to find any physical error causes.
•
If you can find some obvious physical damage, contact ABB for repair or
replacement actions.
3.
Check whether the error is external or internal.
•
Check that the error is not caused by external origins.
•
Remove the wiring from the IED and test the input and output operation
with an external test device.
•
If the problem remains, contact ABB for repair or replacement actions.
7.1.2
Identifying runtime errors
1.
Check the error origin from IED's internal event list
Main menu/Monitoring/
Internal events
.
2.
Reboot the IED and recheck the supervision events to see if the fault has
cleared.
3.
In case of persistent faults, contact ABB for corrective actions.
7.1.3
Identifying communication errors
Communication errors are normally communication interruptions or synchronization
message errors due to communication link breakdown.
•
Check the communication status in the internal event list in
Main menu/
Monitoring/IED status
.
•
In case of persistent faults originating from IED's internal faults such as
component breakdown, contact ABB for repair or replacement actions.
