Basic Relay Operations
Making Simple Settings Changes
When you exit settings entry from the SET commands, the relay responds,
Save settings (Y,N) ?. If you answer Y <Enter>, the relay writes the new
settings to nonvolatile storage. If you answer N <Enter>, the relay discards
any settings changes you have made.
Making Settings Changes: Initial Global Settings
You must configure the relay for specific conditions found in the power
system where you are connecting the relay. In particular, you must set the
nominal frequency and phase rotation.
The procedure in the following steps assumes that you have successfully
established communication with the relay; see Making an EIA-232 Serial Port
Connection for a step-by-step procedure. In addition, you must be familiar
with relay access levels and passwords. See Changing the Default Passwords:
Ter minal to change the default access level passwords.
This example jumps to a Global setting that is not at the beginning of the
Global settings list. Thus, you enter SET G, the setting name, and <Enter>.
To start at the beginning of the Global settings, simply type SET G <Enter>
without a settings name.
Step 1. Prepare to control the relay at Access Level 2.
a. Using a communications terminal, type ACC <Enter>.
b. Type the Access Level 1 password and press <Enter>.
You will see the Access Level 2 => prompt.
c. Type the 2AC <Enter> command.
d. Type the correct password to go to Access Level 2.
You will see the Access Level 2 =>> prompt.
Step 2. Type SET G DATE_F <Enter> (this sets the date format using
the DATE_F setting, which has options of MDY, YMD, or DMY).
The relay responds with a terminal screen display similar to the
beginning of Figure 10.11.
