7
Communication With Relay
There are two ways of communicating with the SEL-710 Motor Relay. You can communicate with the relay using the human-machine
interface (HMI) on the front panel or through serial port communications with a computer. For communications, the computer must
have a serial port and the operating system should be Windows® 2000 or newer. A standard EIA-232 crossover cable or an SEL-234A
cable will also be required.
HMI Pushbuttons
Press the TARGET RESET pushbutton
to clear targets that have been alarmed.
Press the directional (up, down, left, right)
pushbuttons to scroll through options.

ENT
Press the ENT pushbutton

Computer Connection Steps
Step 1.
Connect the PC and the relay using a serial communications cable.
Step 2.
Apply power to both the PC and the relay.
Step 3.
Open a terminal emulation program.
Option 1: ACSELERATOR QuickSet SEL-5030 Software
Open ACSELERATOR QuickSet and proceed to Step 4. If you do not
have ACSELERATOR QuickSet, you can download the program from
www.selinc.com/sel-5030.htm. Refer to Section 3 of the SEL-710
manual for more information about ACSELERATOR QuickSet.
Option 2: HyperTerminal
To open HyperTerminal go to Start > Programs > Accessories >
Communications > HyperTerminal. Once there you will be
prompted to enter a name of your choice for the connection. Then
you will choose which port to connect through. Make sure you select
the same port that you connected the cable to, then click OK.
Step 4.
Set the PC terminal emulation program to the same communications
port settings as shown in the figure to the right and click OK.
Step 5.
Press the <Enter> key on the PC keyboard to check the
communications link. You should see the = prompt. If you do not see
the = prompt, check the cable connections, confirm that the settings
in the terminal emulation program are the default values, and that the
emulation mode is set to VT100.
Step 6.
Once connected, you can set all other relay settings and obtain values
as needed. Refer to Section 6 in the SEL-710 manual for more
information.
SEL-710 Relays are shipped with default passwords. To prevent unauthorized access, change default passwords
to private passwords at installation. SEL shall not be responsible for damage resulting from unauthorized access.
8
Relay Settings
This section of the Express Installation Guide provides a step-by-step process to set the SEL-710 for basic protection purposes. For
more in-depth relay setting procedures, please refer to the SEL-710 manual or contact your local SEL representative. To get more directions on relay setting using PC configuration, please refer to Section 3 of the SEL-710 manual.
Step 1.
Locate the values listed below. Some of the values needed are located on the control center nameplate while others can be
found directly on the motor nameplate.
Find the Values:
CT Ratio (CTR1) =
Full Load Amps (FLA1) =
Service Factor (SF) =
CT Ratio to Ground (CTRN) =
Phase PT Ratio (PTR) =
Line Voltage (VNOM) =
Delta/Wye Connection (DELTA_Y) =
Single V Input (SINGLEV) =
Step 2.
Enter Access Level 2. Whenever prompted for a password, enter the corresponding password. To change the
character, use the arrow keys and press the ENT pushbutton to select the character. Once the full password has been
entered, scroll to Accept and press the ENT pushbutton.

There are three settings sections that need to be set in order to provide basic protection. Navigate to ENT >
SET/SHOW > GLOBAL > General Settings. Once in this menu the following parameters can be set. Complete
these settings to fit the motor connected to the SEL-710 making sure to select NAMEPLATE for the APP
parameter. The other settings should be set to the values taken off the motor nameplate and to your preference.
The warning that scrolls across the top lets you know that the relay will only provide basic and default protection,
which is fine for beginning functionality. This setting will need to be changed to FULL at later date.

Step 4.
The second setting section is Group settings. Navigate to ENT > SET/SHOW > GROUP > 1. In this menu there
are five sections (ID Settings, Config Settings, Thermal Overload, Neutral Overcurrent, Residual Overcurrent) and
there are parameters in each section that must be set. These values can be set from the values taken off the motor
nameplate and control center.
Step 5.
The last setting section is Logic settings. The logic output 103 Fail Safe must be set to Y. The default factory
settings are set to Y so there are no changes that need to be made during this step.

Relay Settings
When APP = NAMEPLATE the following protection is provided by the SEL-710 based on the settings listed previously and hidden
settings (all other protections and warning functions are disabled):
➤ Thermal stator and rotor protection based on motor ratings
➤ Current unbalance protection (20% unbalance, 5 second delay)
➤ Instantaneous phase overcurrent trip level set based on IEEE C37.96 recommendation for phase overcurrent protection
➤ Ground overcurrent protection
➤ Phase overvoltage protection (1.1*VNOM, 0.5 second delay)
➤ Phase reversal protection
➤ Breaker failure protection
To reference all other applications and exact default settings when in this mode, please refer to Section 4 in the SEL-710 manual. The
