Basic Relay Operations
Checking Relay Status
Checking Relay Status Using the Terminal
The procedure in the following steps assumes that you have successfully estab-
lished communication with the relay (see Making an EIA-232 Serial Port Con-
nection on page 3.4). In addition, you must be familiar with relay access levels
and passwords (see Changing the Default Passwords in the Terminal on
page 3.10 to change the default access level passwords).
Step 1. Enter Access Level 1.
a. Using a communications terminal, type ACC <Enter>.
b. Type the Access Level 1 password and press <Enter>.
You will see the Access Level 1 => prompt.
Step 2. Type STA <Enter>. The relay returns a status terminal screen simi-
lar to that in Figure 3.7.
Step 3. Type STA A <Enter> to view all relay status entries.
For more information on relay status report items, see STATUS on
page 14.50.
Checking Relay Status in QuickSet
You can use QuickSet to check relay status. Use the HMI > Meter Control
menu to view status conditions.
The procedure in the following steps assumes that you have successfully estab-
lished communication with the relay (see Making an EIA-232 Serial Port Con-
nection on page 3.4). In addition, you must be familiar with relay access levels
and passwords (see Changing the Default Passwords in the Terminal on
page 3.10 to change the default access level passwords). You should also be
familiar with QuickSet (see Section 2: PC Software).
Step 1. Configure the communications port.
a. Start QuickSet.
NOTE: The DTR parameter has no
effect on communications with the
relay.
b. On the top toolbar, click Communications > Parameters.
You will see the Communication Parameters dialog box
similar to that shown in Figure 3.8.
