ABB Relion 670 series - Diagnosing the IED Status Via the LHMI Hint Menu

The internal events are time tagged with a resolution of 1ms and stored in a list. The list can store up to
40 events. The list is based on the FIFO principle, when it is full, the oldest event is overwritten. The list
cannot be cleared and its content cannot be erased.
The internal events in this list not only refer to faults in the IED, but also to other activities, such as
change of settings, clearing of disturbance reports, and loss of external time synchronization.
The information can only be retrieved from the Parameter Setting software package. The PC can be
connected either to the port at the front or at the rear of the IED.
These events are logged as internal events.

The events in the internal event list are time tagged with a resolution of 1ms.
This means that, when using the PC for fault tracing, it provides information on the:
• Module that should be changed.
• Sequence of faults, if more than one unit is faulty.
• Exact time when the fault occurred.

In order to help the user, there is an LHMI page labeled ‘Hints’. This page is located under Main menu /
