Fault tracing
7.1.1
Identifying hardware errors
1.
Check the module with an error.
Check the IED supervision events in
Main menu/Monitoring/IED status/Self-
supervision
for a faulty hardware module.
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 the IED's supervision events
Main menu/
Monitoring/IED status/Self-supervision
.
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.
•
In case of persistent faults originating from IED's internal faults such as
component breakdown, contact ABB for repair or replacement actions.
7.1.3.1
Checking the communication link operation
•
To verify communication, check that both LEDs above the RJ-45
communication port are lit.
