Section 14
Troubleshooting
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.
14.2.3 Diagnosing the IED status via the LHMI hint menu
In order to help the user, there is an LHMI page labeled 'Hints'. This page is located under Main menu/
Diagnostics/IED status/Hints. For each activated hint there is a headline. From the headline view, an
explanation page can be entered, giving the user more information and hints about the particular topic.
For example, if there is a configuration to use IEC 61850 9–2 analog data, but no data arrives on the
access point, then the IED will use substituted data and most protection functions will be blocked. This
condition will be indicated with a sub-menu under Hints, where details about this condition are shown.
The Hint menu is a way to assist the user in troubleshooting.
