4.3.8 CHANGING SETTINGS

a) ENTERING NUMERICAL DATA

Each numerical setting has its own minimum, maximum, and increment value associated with it. These parameters define
what values are acceptable for a setting.

Two methods of editing and storing a numerical setting value are available.

•

0 to 9 and decimal point

: The relay numeric keypad works the same as that of any electronic calculator. A number is

entered one digit at a time. The leftmost digit is entered first and the rightmost digit is entered last. Pressing the MES-
SAGE LEFT key or pressing the ESCAPE key, returns the original value to the display.

•

VALUE keys

: The VALUE UP key increments the displayed value by the step value, up to the maximum value allowed.

While at the maximum value, pressing the VALUE UP key again allows the setting selection to continue upward from
the minimum value. The VALUE DOWN key decrements the displayed value by the step value, down to the minimum
value. While at the minimum value, pressing the VALUE DOWN key again allows the setting selection to continue
downward from the maximum value.

b) ENTERING ENUMERATION DATA

Enumeration settings have data values which are part of a set, whose members are explicitly defined by a name. A set is
comprised of two or more members.

Enumeration type values are changed using the VALUE keys. The VALUE UP key displays the next selection while the
VALUE DOWN key displays the previous selection.

c) ENTERING ALPHANUMERIC TEXT

Text settings have data values which are fixed in length, but user-defined in character. They can be upper case letters,
lower case letters, numerals, and a selection of special characters.

FLASH MESSAGE

s

For example, select the

 setting.

MINIMUM: 0.5
MAXIMUM: 10.0

Press the HELP key to view the minimum and maximum values. Press the HELP key
again to view the next context sensitive help message.

FLASH MESSAGE
TIME: 2.5 

s

As an example, set the flash message time setting to 2.5 seconds. Press the appropriate
numeric keys in the sequence “2 . 5". The display message changes as the digits are
being entered.

NEW SETTING
HAS BEEN STORED

Until ENTER is pressed, editing changes are not registered by the relay. Therefore, press
ENTER to store the new value in memory. This flash message momentarily appears as
confirmation of the storing process. Numerical values which contain decimal places are
rounded-off if more decimal place digits are entered than specified by the step value. 

ACCESS LEVEL:
Restricted

For example, the selections available for 

ACCESS LEVEL

 are "Restricted", "Command",

"Setting", and "Factory Service".

ACCESS LEVEL:
Setting

If the 

ACCESS LEVEL

 needs to be "Setting", press the VALUE keys until the proper selec-

tion is displayed. Press HELP at any time for the context sensitive help messages.

NEW SETTING
HAS BEEN STORED

Changes are not registered by the relay until the ENTER key is pressed. Pressing
ENTER stores the new value in memory. This flash message momentarily appears as
confirmation of the storing process.
