1. RECEPTION & INSTALLATION
1.1.Relay unpacking
Previously to any handling action, confirm that relay carton box is in good conditions, no broken
or damaged due to external manipulation or during storing or moving process. If packing is
correct, proceed to unpack and you should find following element:
•SIAB Electronic protection relay.
•User Guide.
•Testing protocol.
Testing protocol is a certificate that relay has passed all factory testing process with correct
results.
In case some fault is detected, consider putting into quarantine period the relay and contact
Fanox for further instructions.
1.2.Relay verification
When relay is unpacked, please, take your time to confirm following checking list to be sure that
everything is ok:
•Metallic case not damaged and well assembled. No loose screws due to transport or
movement conditions
•LCD and front cover not damaged or scratched.
•Quality sticker and terminal sticker correctly stuck.
•Rear terminals in good state, being able to do a good wiring connection.

1.3.Powering the relay up
Thanks to the external battery KITCOM the powering and adjusting process of the relay is very
easy and it allows the user to test the relay.
The power comes from two AA batteries (IEC LR06) of 1.5 Volts placed at the bottom of the
kitcom. The equipment has a small Dc/Dc power supply that raises the voltage till the required 5
volts to operate the equipment and that is plugged into the front USB communications port
(KITCOM).
Once the KITCom is connected, the relay will be switched on and a led on the left of the relay
(led on) will blink indicating the relay is powered on through an external battery (KITCOM).
The relay is totally maintenance free. This is, there is no need of batteries to log events and
fault reports and there is no need of batteries to maintain date and time.
NOTE: Date and time must be correctly set the first time the relay is operative and energy
must be kept at least “1 hour” to maintain the RTC for 72 hours once the energy is lost.
Besides, the possibility of using external battery power, together with the possibility of activating
the trip contact from the test menu, allows the trip circuit to be tested before the transformation
center is powered up. So, the KITCOM is useful for cases like commissioning operations,
discharges and repairs to the transformation center.
Using battery power does not block the USB communications port, as it can be used
simultaneously.
Once the relay is powered through the Kitcom, it should be checked:
•Model Directly, complete model on top line and phases/neutral current
measurement on bottom line are displayed. Once “C” key is pressed the name of phase
and neutral currents (instead the complete model) is displayed on the top of LCD
Standby screen.
•Serial Number In “General Settings” menu serial number of 8 digits can be checked
(OK - ▼ - ▼ - ◄ - ▼ - ▼)
•Firmware Version In “Firmware Version” menu (HOLD ▲)

1.3.1.Keypad & LCD
•Use KEYPAD to ensure that all the push-buttons work correctly (no difficulties while
pushing them, check out if the relay reacts by pushing each of the buttons)
•Use KEYPAD to enter in the relay´s menu and make sure that no text is lost while going
from one menu to another.
•Follow the sequence: Left ◄, Down ▼, Right ►, Up ▲, OK, C and RESET and the
following screen should be displayed:
•If the contrast of the LCD is ot the correct one, enter to “CONTRAST” menu by holding
“◄” for 3 seconds. Then, change it by using up and dwon buttons to increase or
decrease the contrast.
1.3.2. Test menu
NOTE: When performing test menu, protection won´t be available and it will be possible to open
circuit breaker. Only authorized personnel can do this job.
Press ◄,▼,► sequentially and hold OK. The relay will ask for the password “5555” to enter to
the test menu (or customer password if default “5555” has been modified).
It will be checked that the LEDs, Magnetic indicator flags and Outputs are activated if OK key is
pressed and it will be deactivated if OK key is pressed again. LEDs, Magnetic indicator and
outputs will be checked to verify the hardware is OK:

5. SPECIFIC CURRENT TRANSFORMERS
SIA-B relay requires specific CTs to achieve not only the line current measurement, but also the
power to keep the relay switched on with tripping capability.
Depending on the requirements there are the following possibilities:

www.fanox.com Installation_Guide_SIAB000B0010AA_Rev. 03 14 / 32
5.1.Test Winding
Unlike the standard current transformers that provide a nominal secondary current of 1A or 5A,
these specific current transformers have a very low current at their secondary.
SIA-B relay has been designed to work with these current levels. For this reason, it is not
possible to do the same tests that are performed with relays that use standard CTs.
The testing consists on the injection of 1A in test winding terminals, providing a simulated
primary current value, that will have a different primary value depending on the selected CT.
6. OPENING MECHANISM
The trip is associated to a striker. The type of trip is a polarized trip. There are a lot of models of
strikers in the market, with different trip energies, being for example 50 mJ (0,05W·s) and
operation voltage of 6V, or 135 mJ (0,1W·s) and operation voltage of 24V.
The opening mechanism is activated by means of a striker. The activation of the trip generates
a pulse train.
The Trip Voltage Level setting allows adjusting the trip voltage level required by the selected
striker. The default value is 17 Vdc, although there are several options:
•12 Vdc
•17 Vdc
•22 Vdc
•24 Vdc
The equipment will allow the trip when it gets the selected trip voltage, so if a lower level that
the required by the striker is adjusted, it may result on tripping without enough energy and not
activating the striker.
On the other hand, if a higher level that the required by the striker is selected, the activation of
the striker is guaranteed, however, the fault trip time during start-up may be increased. Fanox
encourages selecting the correct value of this critical setting and offers its expertise at any
doubt.
Striker
The striker is a bistable device with a simple action. The striker shaft is moved by a spring. The
striker is activated by a polarized low-power electrical signal, supplied by the relay if a fault
occurs. Resetting the shaft to its position is done manually. Resetting the striker has to be done
in such a way as to guarantee that the opening mechanism is closed. This is normally done
manually.
Due to the existing variety in the market, it is important to check the voltage and the necessary
energy for its activation.
