ABB REF 542plus - Resetting alarms

Some alarms might not be reset before the cause that generated it has been removed.
For example, an alarm due to an error in the tripping circuit (coil supervision)
cannot be reset before the tripping coil is replaced. Whereas an alarm generated by a
trip of a protection function is normally reset with this procedure.
