General for a faulty hardware module.
•
Check the history of changes in internal event list in Main menu/
Diagnostics/Internal Events.

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

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

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.
