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 a 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
MESSAGE
left arrow or
pressing the
ESCAPE
key, returns the original value to the display.
•
VALUE keys
— The
VALUE
up arrow increments the displayed value by the step value, up to the maximum value
allowed. While at the maximum value, pressing the
VALUE
up arrow again allows the setting selection to continue
upward from the minimum value. The
VALUE
down arrow decrements the displayed value by the step value, down to
the minimum value. While at the minimum value, pressing the
VALUE
down arrow again allows the setting selection to
continue downward from the maximum value.

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. Press
ENTER
to store the
new value in memory. This flash message momentarily appears as confirmation of the storing
process. Numerical values that contain decimal places are rounded-off if more decimal place digits
are entered than specified by the step value.
