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:

• Exact time when the fault occurred.
12.2.3 Diagnosing the IED status via the LHMI hint menu
GUID-7E8503E9-441B-487A-9CD7-B43463D1CAE5 v3
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.
The Hint menu is currently only available in English. All the entries
are in English, regardless of which language is selected.
The supported list of hints are as follows:

configured to achieve the required accuracy.
Unless a high accuracy time source is selected,
the function dependent on high time accuracy
will be blocked.
SyncLostMode
is set to

, but
there is no UTC capable synch source (GPS,
IRIG-B) used. Unless a UTC capable time
source is selected, the function dependent on
high time accuracy will be blocked.
