What to do if ABB Relays have persistent runtime errors?
If you're encountering persistent runtime errors with your ABB Relays, try rebooting the protection relay first. Then, recheck the supervision events to see if the fault has cleared. However, if the faults persist, you should contact ABB for corrective actions.
How to troubleshoot a faulty hardware module in ABB Relays?
If you suspect a faulty hardware module in your ABB Relays, begin by checking the specific module that's showing an error. Then, review the relay supervision events in Relay Status to pinpoint any faulty hardware modules. Perform a visual inspection of the protection relay. Determine if the error is external or internal. Remove the wiring from the protection relay and test the input and output operation with an external test device. If the problem remains after these steps, or if you observe obvious physical damage, contact ABB for repair or replacement.
