Avoid working alone
Do not use the equipment in gas or explosive vapor areas.
Before using the equipment check cables and coils to see if there is any
mechanical damage; if so replace them. Try to locate breaks or missing plastic
components. Pay special attention to the isolating material that surrounds
connectors.
Disconnect all sensors, cables and accessories that are not being used.
Use the earth connection to connect the equipment to ground and do not
apply voltage.
Do not apply voltages above the nominal working voltage of the equipment.
Before use, check the voltage level coincides with the supply voltage and frequency.
In case of security functions deterioration:
If the equipment is used in a way not specified by the manufacturer, its protections
could become affected.
Before use, check cables and rest of accessories to make sure they are not
damaged; replace them if necessary.
If the equipment or its accessories are damaged or do not work properly, do not use
them and send them for repair.

1. SYSTEM DESCRIPTION
The purpose of this equipment is to achieve the maximum possible information
regarding the low voltage network topology. This means knowing the
connectivity of each accessible point of the LV network.
In this document connectivity is defined as the existing connection relationship
between a network point that is being analyzed, and the MV/LV transformer
substation, feeder and phase that feeds it.
Ariadna ILF12 equipment consists of two devices: Central Device (CD) that is
installed in the MV/LV transformer substation that supplies electricity to the area
whose topology is being achieved, and the Line Device (LD) that is carried by
the operator along the network points whose connectivity is being analyzed. The
CD and the LD communicate with each other using the electric distribution
network.

1.1. Communication between CD and LD in Automatic Mode

CD
LD
INFORMATION
CD injects phase and CD
number identification
signals through each
phase of the MV/LV
transformer.
If the network point where the LD is
connected to belongs to the same
MV/LV transformer, it will receive data
info, which will be shown on the LCD
display.
INFORMATION
After receiving
phase and CD
number, it will
transmit a signal
upstream towards
the transformer.
CD receives this signal
through the sensor ring that
corresponds to the feeder
where the LD has been
connected to.
This way MV/LV transformer, feeder and phase
connectivity information is clearly identified.

INFORMATION
CD identifies the
corresponding feeder
and injects its
identification result code
towards LD.
Receives feeder
identification signal
injected by CD and
displays this
information.

4. CENTRAL DEVICE (CD) EQUIPMENT CONNECTION
Depending on the LV side of the transformer there can be different network
configurations.
4.1. STAR Transformer: 3 phase + neutral LV output
In this LV configuration the transformer will have a neutral cable. Depending on
the network voltage it can be*:
CD connection point
LD connection point
B1 transformers:
oV phase-phase:
230Vac
Vphase-phase:
230Vac
oV phase-neutral:
130Vac
Vphase-neutral:
130Vac
B2 transformers:
oV phase-phase:
400Vac
Vphase-phase:
NOT AVAILABLE
oV phase-neutral:
230Vac
Vphase-neutral:
230Vac
* See equipment working voltage ranges in 5. Technical Features

4.1.1.LD device connection point Phase-Neutral:
Whenever the network point where the LD device is going to be connected,
has an accessible neutral point, the working procedure to connect the CD at
the transformer side should be:
4.1.1.1. Step ONE: Connect sensor rings to feeders
Sensor rings must be connected
checking that each ring embraces all
three phases of a feeder, never the
neutral, and making sure sensor
ring’s polarity (white dot) faces the
transformer side.
The coil must be connected to one of
the BNC inputs of the front panel.

13
4.1.1.2. Step TWO: CD supply cable connection
Connect the supply cable to the CD’s front panel.
It is not possible to work with more than one
transformer at a time, so if there is more than one
transformer in the substation, work must be done with
each transformer separately.
Connect cables to MV/LV transformer’s output:
-F1, green conductor -> Phase
-F2, yellow conductor -> Phase
-F3, brown conductor -> Phase
-N, blue conductor -> Neutral
-GND, green-yellow -> Ground

14
The connection to the network should look like the following figure:

15
4.1.1.3. Step THREE: select working mode, AUTO-FN or MAN-FN modes *
In AUTO mode, the communication between the Central Device and the Line
Device is made automatic, and takes place as described in 1.1 (Communication
between CD and LD).
However, there are certain network points where, due to network topology,
feeder length (over 1km), noise produced by harmonics, etc., it is not possible
for signals from CD to reach the network point where LD device has been
connected to. The MAN mode has been developed for these cases.
When working in MAN mode, the LD works as a transmitter and the CD as a
receiver.
For further information check 6.1 (Identification process: Automatic mode) and
6.2 (Identification process: Manual mode).
*Note: Both UC and UL must be in the same mode:
- UC Automatic mode and UL Automatic mode.
- UC Manual mode and UL Manual mode.

Check CD front panel LEDs:
- If a sensor ring has been connected to the front panel connector its
corresponding LED must turn ON.
Otherwise check the sensor ring’s resistance with an ohm meter.
It should be within 30 to 50 ohm range.
- If no sensor ring has been connected to a front panel connector its
corresponding LED must be OFF.
If all LEDs are blinking check mains connection.
If they still blink, please check supply cable’s connections are good, and
also fuses if necessary.

4.1.2.LD device connection point Phase-Phase:
If the LD connection point has no neutral, and transformer’s LV side is B1 type
(Vphase-phase 230Vac, Vphase-neutral 130Vac) the working procedure
should be as in Transformer LV side in DELTA mode.
Refer to section 4.2 DELTA Transformer: 3 phase LV output (no neutral)
