Table 3 – Level of access: Relays with Cyber Security features
Level management, including password description, management and recovery, is fully
described in section P746/EN CS (relays with Cyber Security features).
Each of the passwords is 4 (or 8) characters of upper case text. The factory default for both
passwords is AAAA (General case). For models with Cyber Security features: default
passwords are blank for Level 1, BBBB for level 2 and AAAA for Level 3. Each password is
user-changeable once it has been correctly entered. Entry of the password is achieved either
by a prompt when a setting change is attempted, or by moving to the 'Password' cell in the
'System data' column of the menu. The level of access is independently enabled for each
interface, that is to say if level 2 access is enabled for the rear communication port, the front
panel access will remain at level 0 unless the relevant password is entered at the front panel.
The access level enabled by the password entry will time-out independently for each
interface after a period of inactivity and revert to the default level. If the passwords are lost
an emergency password can be supplied by contacting General Electric with the relay's
serial number and security code (relays with Cyber Security features). The current level of
access enabled for an interface can be determined by examining the 'Access level' cell in the
'System data' column, the access level for the front panel User Interface (UI), can also be
found as one of the default display options.
The relay is supplied with a default access level of 2 or 3, such that no password is required
to change any of the relay settings. It is also possible to set the default menu access level to
either level 0 or level 1, preventing write access to the relay settings without the correct
password. The default menu access level is set in the 'Password control' cell that is found in
the 'System data' column of the menu (note that this setting can only be changed when level
2 access is enabled).

Relay configuration

The relay is a multi-function device that supports numerous different protection, control and
communication features. In order to simplify the setting of the relay, there is a configuration
settings column that can be used to enable or disable many of the functions of the relay. The
settings associated with any function that is disabled are made invisible, i.e. they are not
shown in the menu. To disable a function change the relevant cell in the 'Configuration'
column from 'Enabled' to 'Disabled'.
The configuration column controls which of the four protection settings groups is selected as
active through the 'Active settings' cell. A protection setting group can also be disabled in the
