Section 7 Troubleshooting7.1 Fault tracing7.1.1 Identifying hardware errors1. 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 the physical error causes.• If you can find some obvious physical damage, contact ABB for repair orreplacement 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 operationwith an external test device.• If the problem remains, contact ABB for repair or replacement actions.7.1.2 Identifying runtime errors1. 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 errorsCommunication errors are normally communication interruptions or synchronizationmessage errors due to communication link breakdown.• In case of persistent faults originating from IED's internal faults such ascomponent 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 communicationport are lit.1MRS756708 A Section 7Troubleshooting615 series 81Operation Manual
