Self-Supervision – Warning Messages
Description
Information
Corrective Action
SW 1…3
– reserved for future use –
—
SW 4 Power Supply
Your device suffered a short-term sag or outage of the
supply voltage.
Check your power supply.
SW 5 No time sync
Warning that the device is operating without time
synchronization.
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).
SW 6 TLS basic cert.
The device uses a basic certificate for the encrypted
communication. Compared with a device-specific
certificate, this means a slightly reduced security
level.
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.
SW 7
– reserved for future use –
—
SW 8 Mult. inval. Conn. Pwd
Warning that a wrong connection password was
entered multiple times in series.
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 Smart view connection).
SW 9 Disturb Rec Trigger
Perpetual trigger of the Disturbance Recorder. Too
many records created during a monitored time span.
Make sure that the Disturbance Recorder is not triggered too
frequently. Check the following settings:
• Configuration of the Disturbance 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
Disturbance 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.
