Information
– reserved for future use –
Your device suffered a short-term sag or outage
of the supply voltage.
Warning that the device is operating without
time synchronization.
The device uses a basic certificate for the
encrypted communication. Compared with a
device-specific certificate, this means a slightly
reduced security level.
– reserved for future use –
Warning that a wrong connection password was
entered multiple times in series.
Perpetual trigger of the Waveform Recorder. Too
many records created during a monitored time
span.

Corrective Action
—
Check your power supply.
If the missing time synchronization is intentional this
warning can be safely ignored.
Otherwise, you should check the synchronization settings
and connection (e. g. for IRIG‑B).
The basic certificate is installed when an old firmware,
that did not support encrypted communication, is
updated by the user.
A device-specific certificate, however, can be installed by
the manufacturer.
—
The message value is the number of wrong password
entries in series. It gets reset to 0 (warning end) when the
connection password is entered correctly (and also with a
restart of the device).
You should check whether this indicates an unauthorized
access attempt (as the connection password is needed to
establish a PowerPort-E connection).
Make sure that the Waveform Recorder is not triggered
too frequently. Check the following settings:
•
• Configuration of the Waveform Recorder: Verify that
each of the defined trigger sources is configured by
intention.
• In the Event Recorder, you can see which protection
•
function creates excessive events (as trigger for
the Waveform Recorder). Check the settings of
this protection function, especially the alarm levels.
Adapt them, if necessary.
•
• Device Planning: Make sure that no superfluous
protection functions are projected that you do not
need.
