Text setpoints have data values, which are fixed in length, but user defined in
character. They may be comprised of uppercase letters, lowercase letters, numerals,
and a selection of special characters. The editing and storing of a text value is
accomplished with the use of the decimal [.], VALUE, and ENTER keys.
For example:
1. Move to message
S3 DIGITAL INPUTS
and scrolling with the VALUE keys, select "General Sw. A". The relay will display
the following message:
INPUT 1 FUNCTION:
General Sw. A
2. Press the MESSAGE key to view the next setpoint,
this user defined input will be changed in this example from the generic
"General Sw. A" to something more descriptive.
3. If an application is to be using the relay as a station monitor, it is more
informative to rename this input "Station Monitor". Press the decimal [.] key to
enter the text editing mode. The first character will appear underlined as
follows:.
SWITCH NAME:
General Sw. A
4. Press the VALUE keys until the character "S" is displayed in the first position. Now
press the decimal [.] key to store the character and advance the cursor to the
next position. Change the second character to a "t" in the same manner.
Continue entering characters in this way until all characters of the text "Stn.
Monitor" are entered. Note that a space is selected like a character. If a
character is entered incorrectly, press the decimal [.] key repeatedly until the
cursor returns to the position of the error. Re-enter the character as required.
Once complete, press the ENTER key to remove the solid cursor and view the
result. Once a character is entered, by pressing the ENTER key, it is automatically
saved in flash memory, as a new setpoint.
