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:
•
•
•
SIAC 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 to put 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.

Powering the relay up with kitcom
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 12 volts to operate the equipment and that is plugged into the front RS232
communications port (KITCOM).
Once the KITCom is connected, the relay will be switched on and a led on the right of the
relay (led battery) 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, it is clear the KITCOM useful for cases like
commissioning operations, discharges and repairs to the transformation center.
Using battery power does not block the RS232 communications port, as it can be used
simultaneously.
Once the relay is poowerd 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 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 ▲)

Keypad & LCD
•
Use the KEYPAD, 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 the KEYPAD to enter in the relay´s menu and make sure that no text is lost while
going from one menu to another.
•
•
1.3.2.
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 not the correct one, enter to “CONTRAST” menu by holding
“◄“for 3 seconds. Then, change it by using up or down buttons to increase or decrease
the contrast.
Test menu
NOTE: When performing test menu, protection won´t be available and it will 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:

OPENING MECHANISM
The trip is associated to a striker. The type of trip is a polarized trip, this is, the trip is
associated to a striker. 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.

PROGRAMMABLE LOGIC CONTROL
Physical outputs are the real outputs of the Device. SIA C has a trip output and other three
digital outputs (Output 2, Output 3 and Output 4). SIA C device has 3 configurable LEDS,
which receive the same treatment as the physical outputs. All the outputs (Leds and physical
outputs) are the result of a PROGRAMMABLE LOGIC CONTROL which can be configured
from HMI or from SICom software.
For each output, there is a LOGICAL GATE. It can perform a logical operation up to 4 binary
states to obtain other binary result. In V3 of the PLC the LOGICAL GATES that are
supported by SIAC are:

NOTE: It is checked that thermal image values are re-defined not to exceed the declared value
in the International Standard:
Commisioning recommendation:
•
It is recommended to use Kitcom accessory for relay protection functions settings.
Connect it for setting and disconnect it for testing purpose.
•
Adjust manually current generation value without injecting current to relay, for not
stressing it during adjustment process.
Be sure that relay output contact is connected to generator tripping input in order to stop
the generator, hence the current injection, after reaching adjusted tripping time. This
way, relay will only withstand rated injected current during adjusted time at protection
function settings, not maintaining current injection constantly, which could become a
damaging situation for relay, as in other case, the internally handle energy will be higher
than rated one.
•
•
Not to perform repetitive trips continuously as the stress of the relay will be increased
drastically, especially when high current is being injected on the relay.
By following these recommendations, relay should pass commissioning test successfully. If
commissioning test is performed not following these recommendations, manufacturer won’t be
responsible for relay failure

Measurements
The accuracy of the measurement is ±2% on a band of ±20% over the nominal current
and ±4% over the rest of the measurement range.
It is shown some examples below:
-
Current inyected => I=1xIn: ±2% accuracy is complied.
-
Current injected => I=2 xIn as this current value is 20% higher than the nominal
current  4% accuracy is complied.

Protection functions
Current injection procedure:
Adjust the Sverker current generator with HOLD 0,2 xIn, and suddenly, inject it to the relay,
as it would happened in real situation when circuit breaker is close, powering network line.
From this value, increase the current to achieve the function pick-up and the function trip.
