Functional Testing
Do not apply any signal to pin VB.Commissioning Testing
Introduction
Before any SEL-2414 devices leave our factory, SEL performs a complete func-
tional check and calibration of each device. This helps to ensure that you receive
a device that operates correctly and accurately.
Commissioning tests should verify that the device is properly connected to the
auxiliary equipment. In order to verify control signal inputs and outputs use an ac
connection check to verify that the device current and voltage inputs are of the
proper magnitude and phase rotation.
Brief functional tests ensure that the device settings are correct. It is not neces-
sary to test every element, timer, and function in these tests.
The following procedure is a guideline to help you enter settings into the
SEL-2414 and to verify that it is properly connected. Modify the procedure as
necessary to conform to your standard practices. Use this procedure at initial
device installation; you should not need to repeat it unless major changes are
made to the device electrical connections.
Required Equipment
➤ The SEL-2414, installed and connected according to your design.
➤ PC with serial port, terminal emulation software, and serial
communications cable.
➤ SEL-2414 Settings Sheets with settings appropriate to your
application and protection design.
➤ AC and dc elementary schematics and wiring diagrams for this
device installation.
➤ Continuity tester.
➤ Protective device ac test source:
➢ Minimum: single-phase voltage and current with phase
angle control.
➢ Preferred: three-phase voltage and current with phase
angle control.
Procedure
Step 1. Remove control voltage and ac signals from the SEL-2414 by
opening the appropriate breaker(s) or removing fuses.
Step 2. For safety, isolate the device output contacts assigned to control
external equipment.
The device contains devices sensitive
to Electrostatic Discharge (ESD).
When working on the device with the
front panel removed, work surfaces
and personnel must be properly
grounded or equipment damage may
result.

CAUTION
Step 3. Verify correct ac and dc connections by performing point-to-point
continuity checks on the associated circuits.
Step 4. Apply ac or dc control voltage to the power supply of the
SEL-2414. After the device is energized, the front-panel green
ENABLED LED must illuminate.
Step 5. Use the appropriate serial cable (SEL Cable C234A or equivalent)
to connect a PC to the device.
Step 6. Start the PC terminal emulation software and establish
communication with the device (refer to Section 7:
Communications for more information on serial port
communications).
Step 7. Set the correct device time and date by using either the front-panel
or serial port commands.
