Enumeration data
Enumeration settings have data values that are part of a set, whose members are explicitly defined by a name. A set has
two or more members.
Enumeration type values are changed using the
VALUE
keys. The
VALUE
up arrow displays the next selection while the
VALUE
down arrow displays the previous selection.
Alphanumeric text
Text settings have data values that are fixed in length, but user-defined in characters. They can be upper-case letters,
lower-case letters, numerals, and a selection of special characters.
There are several places where text messages can be programmed to allow the relay to be customized for specific
applications. One example is the Message Scratchpad. Use the following procedure to enter alphanumeric text messages.
For example, enter the text “Breaker #1”.

Press the decimal point to enter text edit mode.

Press the
VALUE
keys until the character 'B' appears; press the decimal key to advance the cursor to the next position.
3.
Repeat step 2 for the remaining characters: r,e,a,k,e,r, ,#,1.
4.
Press
ENTER
to store the text.

to view context sensitive help. Flash messages appear sequentially for several
seconds each. For the case of a text setting message, pressing
HELP
displays how to edit and store new values.

panel. Navigate out and back into the menu for activation.
