8 LOCAL USER INTERFACE
The cursor is positioned on the second line and 'n' indicates the current group number. If group number selec-
tion is controlled by Contact Converter inputs, the display will contain the word EXTERNAL.
When the active group number is changed, the equals sign (=) will be replaced by a blinking colon (:) until the
[ENT] key is pressed. A value between 0 and 4 can be entered. Entering 1 to 4 followed by the [ENT] key
selects Protection Settings group 1 to 4. Entering '0' informs the relay to read the active group number from
Contact Converter inputs. If any number other than 0 to 4 is entered, an error message is displayed on the sec-
ond line until the [CLR] key is pressed.
This command is used to display or change the current date and/or time stored in the relay. SETTING or MAS-
TER privilege level is required to make this change, however, users with any privilege level can view the date
and time. When this item is selected, the display looks as shown below:
The cursor will be located on the second line. To change the date or time, place the cursor on the desired line
and press the [ENT] key.
Enter the 6 digits corresponding to the correct date or time from the numeric keypad and press the [ENT] key.
When the first digit is entered, the 6 digits on the display are blanked and the equals sign (=) is replaced by a
blinking colon (:) until the [ENT] key is pressed. If the entered digits do not compose a valid date or time, the
old date or time is retained and an error message is displayed.
In both cases, two checks are performed: privilege level must be SETTING or MASTER and entered data must
be in the correct format. If the checks fail then an error message is displayed and the change is not performed.
The [ACT] key is used to select Action Commands. All Action Commands except LUI Test require either CON-
TROL or MASTER privilege level. The KEYPAD/DISPLAY INTERFACE Test can be performed with any privi-
lege level. The PASSWORD ENABLE/DISABLE command and all relay tests require MASTER privilege level.
