SEL-411L Relay Protection Manual Date Code 20151029
Time-Synchronized Measurements
Configuring High-Accuracy Timekeeping
This example assumes that you have successfully established communication
with the relay (see Making an EIA-232 Serial Port Connection on
page P.10.5). In addition, you must be familiar with relay access levels and
passwords (see Changing the Default Passwords: Terminal on page P.10.9 to
change the default access level passwords). Also, you should be familiar with
ACSELERATOR QuickSet (see Section 6: PC Software).
Step 1. Configure the communications port.
a. Start
ACSELERATOR QuickSet.
b. On the top toolbar, open the Communications menu,
and then click Parameters.
You will see the Communication Parameters dialog
box similar to Figure 13.7.
c. Select the Data Speed, Data Bits, Stop Bits, Parity,
and RTS/CTS that match the relay settings.
The defaults are 9600, 8, 1, None, and Off,
respectively.
d. Click OK to update the
ACSELERATOR QuickSet
communications parameters.
e. Confirm that the Communications Status bar at the
bottom of the
ACSELERATOR QuickSet window says
Connected.
Step 2. Confirm the correct
ACSELERATOR QuickSet passwords.
a. Reopen the Communication menu and click
Parameters.
b. Enter your Access Level 1 password in the Level One
Password text box, and your Access Level 2 password
in the Level Two Password text box.
c. Click OK to accept changes and close the dialog box.
Step 3. Read the present configuration in the relay. Click Settings >
Read.
The relay sends all configuration and settings data to
ACSELERATOR QuickSet.
Step 4. Access the protection free-form SEL
OGIC settings.
a. Click the + mark next to Group 1 in the Settings tree
view.
b. Click the Protection Logic 1 settings (see Figure 13.4).
Step 5. Enter the two lines of SEL
OGIC control equation programming
in the Protection Free-Form Logic Settings shown in
Figure 13.4.
Comments begin with the # character (see Fixed SEL
OGIC
Control Equations on page P.14.4).
