Fault tracing

Identifying hardware errors

1. Check the module with an error.
• Check the general IED status in Main menu/Diagnostics/IED status/
General for a faulty hardware module.
• Check the history of changes in internal event list in Main menu/
Diagnostics/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.

Identifying runtime errors

1. Check the error origin from IED's internal event list Main menu/
Diagnostics/IED status/General.
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.

Identifying communication errors

Communication errors are normally communication interruptions or synchronization
message errors due to communication link breakdown.
• Check the IEC61850 and DNP3 communication status in internal event list in
Main menu/Diagnostics/IED Status/General.
• In case of persistent faults originating from IED's internal faults such as
component breakdown, contact ABB for repair or replacement actions.
