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.

rounded-off if more decimal place digits are entered than specified by the step value.
