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.
The supported list of hints are as follows:
Table 21:
Headline
Incorrect setting of SyncLostMode
Sampled value substituted
Time diff: IED vs Sampled value
Frequency diff: IED vs Sampled value
Wrong cycle time for PMU report
PMU not connected to 3ph output
Table continues on next page

The Hint menu is currently only available in English. All the entries are in English,
regardless of which language is selected.

Explanation
There are two explanations possible:
SyncLostMode is set to Block, no time source is 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 BlockOnLostUTC, 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.

Wrong cycle time on SMAI or 3PHSUM block connected to
Phasor Report block. The SMAI or 3PHSUM block should
have same cycle time as that of Phasor Report.
The PMU phasor report input(s) must be connected to the
3ph output of SMAI or 3PHSUM.
