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.
FLASH MESSAGE
TIME:
1.0 s
MINIMUM:
0.5
MAXIMUM:
10.0
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 will allow 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 mini-
mum value. While at the minimum value, pressing the VALUE DOWN key again will allow the setting selection to con-
tinue downward from the maximum value.

MESSAGE TIME
Press the HELP key to view the minimum and maximum values. Press the HELP key
again to view the next context sensitive help message.
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 will change as the digits are
being entered.
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 will momentarily appear
as confirmation of the storing process. Numerical values which contain decimal places
will be rounded-off if more decimal place digits are entered than specified by the step
value.
For example, the selections available for
"Setting", and "Factory Service".
If the
needs to be "Setting", press the VALUE keys until the proper selec-
ACCESS LEVEL
tion is displayed. Press HELP at any time for the context sensitive help messages.
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.
