Settings
Parameter changes can be entered from the device fascia. These can be for the Function Groups (FG) or
Function Elements (FE) i.e. the Settings > Function menus. 4 settings groups are provided for each
function – Group number (Gn) 1 to 4.
NOTE
Where the Setting Confirmation ID has been enabled this must be entered to allow changes.
At any 1 time only 1 group of settings can be active – Device Config > Active Group setting, (see
3.2 Device Configuration ).
Settings data is stored in non-volatile memory in the device.
Instruments
The device instrumentation and metering provides real-time measured quantities and data, this is displayed on
the relay fascia LCD (when in Instruments Mode) or via the data communications interface.
The primary values are calculated using the CT and VT parameters i.e. the values entered in the Configura-
tion > CT/VT menu, (see 3.3 CT and VT Inputs ).
The user can add the meters that are most commonly viewed to a Favorites window by pressing the Enter
key when viewing a meter. The relay will display the favorite meters after elapse of the Configuration >
Device > Favorite Meters Timer setting. When more than 1 favorite meter is selected each selected
meter is displayed on the LCD for 5 seconds.
The energy storage meters can be reset from a binary input and have a user selectable setting for their meas-
urement in the Configuration > Data Storage menu, (see 3.6 Data Storage ).
Counter instruments can be reset by pressing the ▶ key when the instrument is displayed.
Communication Meters
The communications meters display the information and activity.
The screen itself depends on the module type and is available only in English.
Control Mode Menu
This mode provides convenient access to commonly used relay control and test functions. When any of the
items highlighted in the control menu are selected control is initiated by pressing the Enter key. The user is
prompted to confirm the action, again by pressing the Enter key, before the command is executed.
NOTE
Control ID access code entry may be necessary to carry out control commands from the device, (see
3.2 Device Configuration ).
NOTE
A CB must be in a Closed state before an Open command will be accepted. And that a CB must be in an
Open state before a Close command will be accepted. If not, the relay reports that the requested
command is Interlocked.
NOTE
Switching a protection function In/Out via the Control Mode menu will not change that function
group’s Enabled/Disabled setting. The Control Mode menu selection will however over-ride the
setting when disabling or switching the function out of service.
