Basic Relay Operations
Making Simple Settings Changes
Text-Edit Mode Line Editing
Some relay settings present multiple input lines to your terminal; you use
basic line text editing commands to construct the setting. For display, the relay
references each line of the setting by line number, not by the setting name. See
Making Text-Edit Mode Settings Changes for an example of a text-edit mode setting.
While in the text-edit mode, you see a prompt consisting of the line number
and the present setting for that line. You can keep the setting, enter a new
setting, or delete the setting. Table 10.6 lists the commands for text-edit mode.
Use commas to separate the items in a text-edit mode setting when you are
entering multiple items per line. After you enter each line, the relay checks the
validity of the setting. If the entered setting is invalid, the relay responds with
an error message and prompts you again for the setting.
Making Text-Edit Mode Settings Changes
The procedure in the following steps familiarizes you with basic text-edit
mode line editing. You set Display Points 1–3 to show the status of Circuit
Breaker 1, Circuit Breaker 2, and the operational state (on or off) of the
transformer cooling fans near the circuit breaker bay where you have installed
the relay. See Display Points on page P.7.8 for information on programming
display points.
For this example, use inputs IN201, IN202, and IN205. You can use other
inputs for your particular application. See Control Inputs on page P.2.5 for
more information on control inputs.
This procedure assumes that you have successfully established
communication with the relay (see Making an EIA-232 Serial Port
Connection) In addition, you must be familiar with relay access levels and
passwords (see Changing the Default Passwords: Terminal) to change the
default access level passwords.
Table 10.6 Actions at Text-Edit Mode Prompts
Action Relay Response
Enter> Accept the setting and move to the next line; if at the last line or
at a blank line, exit settings.
>n <Enter> Move to line n. If this is beyond the end of the list, move to a
blank line following the last line.
^ <Enter> Move to the previous line; if at the first line, stay at the present line.
< <Enter> Move to the first line.
> <Enter> Move to a blank line following the last line.
LIST <Enter> List all settings and return to the present action prompt.
DELETE n <Enter> Delete the present line and subsequent lines for a total of n lines;
n = 1 if not provided. Lines after deletion shift upward by the
number of lines deleted.
INSERT <Enter> Insert a blank line at the present location; the present line and
subsequent lines shift downward.
END <Enter> Go to the end of the present settings session. Prepare to exit
