Figure 26: Default display navigation
If the device is not yet configured for NERC compliance (see Cyber-security chapter), a warning will appear
when moving from the "NERC compliant" banner. The warning message is as follows:
DISPLAY NOT NERC
COMPLIANT. OK?
You will have to confirm with the Enter button before you can go any further.
Note:
Whenever the IED has an uncleared alarm the default display is replaced by the text Alarms/ Faults present. You
cannot override this default display. However, you can enter the menu structure from the default display, even if the
display shows the Alarms/Faults present message.
2.5 PASSWORD ENTRY
Configuring the default display (in addition to modification of other settings) requires level 3 access. You will
be prompted for a password before you can make any changes, as follows. The default level 3 password is
AAAA.
