Fault tracing

Identifying hardware errors

1. Check the module with an error.
Check the relay supervision events in Main menu/Monitoring/IED status/Self-
supervision for a faulty hardware module.
2. Inspect the protection relay visually.
• Inspect the protection relay 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 protection relay 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 the protection relay's supervision events Main menu/
Monitoring/IED status/Self-supervision.
2. Reboot the protection relay 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.
• In case of persistent faults originating from protection relay's internal faults such as
component breakdown, contact ABB for repair or replacement actions.
