1 INTRODUCTION AND SAFETY TIPS
INTERNATIONAL CAPACITORS S.A. thanks you for choosing one of the regulators from the PFCL Elite
series. These units have been built with state-of-the-art technologies, including a powerful processor that can
calculate the optimum algorithms and achieve the best correction of the cos ij.
The units comply with the EN 61010 Electrical Safety Standard, in accordance with the Low Voltage Directive
requirements (LVD 73/23/EC), as well as the EMC Directive (2004/108/EC) and are, therefore, certified for
use with the CE mark.
The purpose of this user manual is to describe the operating principles for the regulators from the PFCL Elite
series and to define the installation, start-up and operation procedures.
SAFETY
The installation and maintenance of the equipment must be performed by qualified and
authorised staff, in accordance with the national and international Standards. Any
manipulation or use of the equipment different from that specified by the manufacturer
may compromise user safety.
The main switch must be disconnected before any maintenance to be performed on the cos ij
regulation equipment. After the main switch has been disconnected, wait at least 5 minutes to make
sure that all capacitors have been discharged.
The following safety precautions must be taken into account during installation, maintenance or start-up
operations on equipment regulated with a PFCL Elite unit:
9Make sure that the units have the corresponding earthing connections before they are connected. A
faulty earthing connection could lead to a faulty operation and represent the risk of electrical
discharge to the user or person handling the equipment.
9The necessary precautions will be taken during maintenance operations to prevent the risk of
electrocution and electric shock. Make sure that the unit has been disconnected and wait until the
capacitors have been fully discharged before handling or operating the unit. We recommend the use
of safety goggles and gloves.
9Resonance can be produced when the power factor compensation units are connected with no
loads. In this case, the voltage harmonics can be amplified, causing damage to the compensation
equipment and other equipment connected to the network.
9Follow the start-up and stop procedures described in the manual to prevent damage to the unit
and/or adjacent equipment.
9Always use original spare parts or components when adjusting or replacing components and follow
the corresponding procedures described in the instruction manual.
1.1 Checks to be carried out when the regulator is received
On receiving the regulator, check that:


The unit has not been damaged during transport.


The type supplied is the same as that requested. (See label on the rear, Fig. 1.1)


Check the features shown on the unit's label, to make sure that they are valid for the type of grid
where the unit will be connected. (Voltage and power supply frequency, measurement range, etc.)


Follow the instructions described in section 2, in relation to the rest of the installation and setup.


Please contact the technical-commercial service of INTERNATIONAL CAPACITORS, SA if you

1.2 Definitions
The following definitions might be useful to understand some of the sections in this manual.
1.2.1 4-Quadrant Regulator.
The regulator is capable of performing the measurement and regulation functions when the active power is
transferred from the grid to the loads (common case in a consumer installation) or when the load is
transferred to the grid (this is the case of installations with generators that not only allow the consumption of
energy, but can also export and sell energy).
1.2.2 FCP System (FAST Computerized Program).
This system controls the connection sequence of the different stages, tending to minimise the number of
operations and matching the usage times of the different stages to achieve the determined final power
demand. The operations are carried out in such a way that, in the case of stages with an identical power, the
stage that has been disconnected the longest is connected when there is demand and the stage that has
been connected the longest is disconnected in the case of a surplus.

1.2.3 Stages and Steps
We must explain the difference between stages and steps. In this manual, a STAGE is described as the
capacitor banks in which the power factor compensation unit is divided, which may have different power
ratings, usually in 1:1, 1:2, 1:2:4, etc. ratios.
A step is each one of the total power fractions (power of the first step) that can be regulated with the use of
stages with a different weight.
1.2.4 Regulation Program.
The power ratings of the different groups or stages usually follow certain patterns called "programs”. The
program indicates the power ratios between different stages. The most frequent programs are:
Program 1:1:1:1. All stages have the same power. For example, a 100 kvar unit with 5 steps would be
composed of 5 identical 20 kvar stages and it would be described as a (5 x 20) kvar unit.
Program 1:2:2:2. All stages after the second stage have twice as much power as the first stage. For
example, a 180 kvar unit with 5 stages would be composed of a first 20 kvar stage and 4 identical 40 kvar
stages. It could be described as a (20 + 4 x 40) kvar unit.
Program 1:2:4:4. The power of the second stage is twice as much as the first stage and all other stages
after the third stage would have four times as much power as the first stage. For example, a 300 kvar unit
with 5 stages would be composed of a first 20 kvar stage, a second 40 kvar stage and 3 identical 80 kvar
stages. It could be described as a (20 + 40 + 3 x 80) kvar unit.
Other Programs. Other programs can be used, such as 1:2:2:4, 1:2:4:8 or 1:1:2:2, etc. The meaning of the
numbers, as assumed in previous cases, shows the proportion of the powers between the first stage, which
receives a value of 1 and the next stages (2 means twice as much power, 4 means four times as much
power, etc.).
The unit can easily configure one of the 10 standard programs, which are as follows:
1:1:1:1, 1:2:2:2, 1:2:4:4, 1:2:4:8, 1:1:2:2, 1:1:2:4, 1:2:2:4, 1:2:3:3, 1:2:3:4, 1:2:3:6.
An open program can also be configured between 1:1:1:1 and 1:9:9:9 in special cases.
1.2.5 Plug and Play.
A series of parameters must be configured when a power factor regulator is installed, to make sure that it
operates correctly. Some of these parameters might be hard to know, such as, for example, the voltage
phases or the voltage corresponding to the current measured, as well as the current transformer ratio. PFCL
Elite has been designed with a smart automatic process that detects the necessary parameters, such as:
¾C/K: calculates the ratio of the current transformer and the power of the smallest step.
¾Phase: Identifies the voltage sequence and correspondence with current. In other words, it identifies
the U
L1
, U
L2
, U
L3
, when the current measured is I
L1
, I
L2
, I
L3
and whether it is connected in the
opposite way or not.
¾Number of stages installed and Program: the system connects all stages in a sequence, finds out
how many stages are installed and then calculates the program, i.e., the power ratio of the
capacitors (see Section 1.2.4).
1.2.6 Connection and Reconnection Time.
Connection time Tc defines the minimum time between changes in the status of stages, i.e., between
connections and disconnections. Therefore, the configuration of this parameter has a direct impact on the
compensation speed, in other words, on the monitoring capacity after changes in load. Establish a shorter
connection time to improve the power factor correction when the load can change quickly.
However, a shorter Tc will lead to a higher number of connections per time unit, shortening the useful life of
the associated components (contacts, capacitors). To assess the number of connections, PFCL Elite uses
individual meters for each capacitor.
The reconnection time is the minimum time between the disconnection of a stage and its reconnection. This
time is required to discharge the capacitor enough to prevent an over-current in the system after it is
reconnected.

1.2.7 Harmonics and THD
Non-linear loads, such as those in rectifiers, inverters, speed drives, kilns, etc., absorb non-sinusoidal
periodic currents from the grid. These currents are composed of a fundamental frequency component, rated
at 50 or 60 Hz, plus a series of overlapping currents, with frequencies that are multiples of the fundamental
frequency; they are defined as harmonics. The result is a deformation of the current and, as a consequence,
of the voltage, which leads to a series of associated secondary effects (overloads in conductors, machines
and automatic switches, phase offsets, interferences in electronic equipment, RCCB trips, etc.).
The level of harmonics is usually measured with the total harmonic distortion rate (THD), which is the ratio,
usually as a %, of the RMS value of the harmonic content and the value of the fundamental component.
2 INSTALLATION AND START-UP
This section contains information and warnings that the user must respect at all times to guarantee his own
safety and the safe operation of the device.
WARNING! The PFCL Elite regulators are connected to units with capacitors that remain
charged even after the voltage has been disconnected. Wait at least 5 minutes after the
equipment is disconnected, before the internal components of the equipment are handled, in
order to avoid the risk of electric shock.
Any manipulation or use of the equipment different from that specified by the
manufacturer may compromise user safety.
The power supply must be disconnected from the unit when it shows signs of deterioration or a faulty
operation. In this case, contact a qualified service representative.
The persons responsible for the installation or operation of the PFCL Elite 6 or PFCL Elite 12 regulator must
follow the common safety measures for LV or MV installations to guarantee a safe operation, depending on
the installation location. In addition, they must take into account all safety warnings stated in this instruction
manual.

2.2 Equipment Installation
2.2.1 Mechanical Installation
In mechanical terms, the equipment is installed in a cabinet's front panel or in a panel. The panel fixing drill
must be drilled in compliance with DIN 43 700, (dimensions: 138+1x138+1 mm).

PFCL Elite 6 / PFCL Elite 12

2.2.2 Connections
The following points must be checked before the unit is powered:
The installation and maintenance of the equipment must be performed by qualified and
authorised staff, in accordance with the national and international Standards.
All connections must remain inside the electrical panel.
Take into account that, when the device is connected, the terminals may be hazardous to the
touch, and opening the covers or removing elements may expose these parts. Do not use the
device until it is fully installed.
This regulator has a series of associated capacitor units that remain charged up to 5 minutes
after the unit has been disconnected from the grid. Make sure that all capacitors have been
discharged before handling the unit.
The installation of an external current transformer (CT) is necessary to measure the current. Usually, the
transformation ratio of this CT is In/5 A, where Inmust be a minimum of 1.5 times over the total maximum
current of the load.
The current transformer (CT) must be installed on the connection point where all of the loads' current
circulates and where the current of the capacitors will be compensated (see Fig. 2.1).
The current transformer (CT) should preferably be connected to phase L1, while the voltage connections
should be connected to phases L1, L2 and L3 (see diagram in Fig. 2.2). Connections P1, P2, S1 and S2
shown on the said diagrams should be respected. In case the connection layout mentioned above is not
respected, the phase must be adjusted, following the procedure described in section 5.5.
&255(&7 ,1&255(&7

The current transformer (CT)
must measure the joint current
of the capacitors and the loads.
If this does not work, make
sure that the CT is not short-
circuited.

When the CT is connected in this
position, NO CAPACITORS WILL
BE CONNECTED, even when
inductive loads are present. The
unit will not perform the
compensation functions.



When the CT is connected in this
position, ALL CAPACITORS WILL
BE CONNECTED. However, they
will not be disconnected when the
load decreases.
Risk of over-compensation in the
grid with no load.

2.2.3 Cable sections and protection elements
The power circuit must be protected with gl (IEC 269) or M type fuses (IEC 127) with a rating of 0.5 to 2 A. A
circuit breaker or equivalent device must be used to connect and disconnect all of the unit's control circuits
(PFCL Elite power supply + relay circuits and contact coils) from the power supply grid. The circuit breaker
must be installed on the equipment and be easy to access. The power circuit and relay contact circuits must
be connected with cables with a minimum section of 1.5 mm
2
. The cables of the current transformer's (CT)
secondary must have a minimum section of 2.5 mm
2
. In the case of distances between the CT and the
regulator over 25 m, this section must be increased by 1 mm
2
for every 10 m.

5 REGULATOR'S OPERATION
5.1 Start-up Screen
A start-up screen will be displayed when the PFCL Elite is powered, showing the
unit's version, voltage model and number of relays available. This information must
be included when reporting any fault or defect.
After a few seconds, the unit will display the first measurement screen, i.e., the default
screen.
5.2 Device States
The PFCL Elite regulators can have two states:
-Normal State (RUN): This is the normal operating state of the regulator, where it measures the installation's
cos ij, among many other parameters, and automatically regulates the connection and disconnection of
capacitors to correct this value. The regulation method depends on different parameters configured in the
setup state (SETUP).
The variable measurement screens will always be displayed when the unit is in the Normal state. The unit will
automatically open this default screen after 10 minutes of inactivity and no key is pressed (see Section 5.3).
The Manual Connection/Disconnection of Capacitors can only be carried out in this state by holding
keys or key .
Hold down key to change the state from normal to setup. The regulator will sequentially disconnect all
capacitors that are connected before opening the setup state.
-Setup State (SETUP): The different work parameters of the regulator can be configured in this state.
Likewise, the equipment will not perform the regulation functions while active in this state, i.e., it will not
connect or disconnect capacitors to regulate cosine.
The setup screens will always be displayed when the unit is in the Setup state. The unit will automatically
open the verification screen after there are 10 minutes of inactivity and no key is pressed (see Section 5.5).
Likewise, if there are another 10 minutes of inactivity and no key is pressed, the unit will automatically return
to the Normal state (RUN) on the default screen (see Section 5.3).
Hold down key to change from the setup state to the Normal state. A verification screen will be displayed
first. Confirm the change to the Normal state by holding down . Or, press
to continue in the setup state.

5.3 Measurement Screens
In the normal state, the regulator measures different parameters, which can be displayed on different
screens. The device also acquires the maximum and minimum values of the said parameters and displays
them after the last reset, even after the unit is turned off and restarted.
All measurement screens show the capacitors that are connected at that moment, the flashing backlight and
the alarm icon. Most screens also display the alarm code.
The unit's measurement screens are as follows (in order):
Default screen: Cos III, phase-phase voltage III and current (PM1; TypeM1):
The following data is displayed:
¾Three-phase cosine and its type ( inductive or capacitive).
¾Three-phase phase-phase voltage.
¾Current.
The EXPORT word under the icon that shows the type of cosine indicates
that the power measured is exported. When the installation is consuming
(importing) power, the PHASE parameter must be reconfigured in the
setup menu.
Three-Phase Power Screen (PM2; TypeM1):
The following data is displayed:
¾Three-phase active power (in kW).
¾Three-phase reactive power and its type ( inductive, or
capacitive) (in kvar).
¾Apparent power (in kVA).
Phase-neutral voltage screen (PM3; TypeM1):
The following data is displayed:
¾L1 Phase-neutral voltage, with respect to the neutral (in V).
¾L2 Phase-neutral voltage, with respect to the neutral (in V).
¾L3 Phase-neutral voltage, with respect to the neutral (in V).
¾Frequency (in Hz).
Phase-Phase Voltage Screen (PM4; TypeM1):
The following data is displayed:
¾Phase-phase voltage of L1-L2 (in V).
¾Phase-phase voltage of L2-L3 (in V).
¾Phase-phase voltage of L3-L1 (in V).
¾Frequency (in Hz).

Currents and Temperatures Screen (PM5; TypeM1):
The following data is displayed:
¾Current (in A).
¾Leakage current (in mA).
¾Temperature (in ºC).
Comments about temperature measurements:
the unit uses an internal sensor to display the approximate external
temperature of the equipment (internal cabinet temperature), which will be
reached when the current conditions remain stable: number of stages
connected, ventilation (forced or not), external cabinet temperature, load
consumption, etc. If these parameters are not stable, the error in the
temperature reading can increase significantly.
Cos III and PF Screen (PM6; TypeM1):
The following data is displayed:
¾Three-phase cosine and its type ( inductive, or capacitive).
¾Power factor, PF.
THDs Screen (PM7; TypeM2):
The following data is displayed:
¾THD harmonic distortion of the voltage (in %).
¾THD harmonic distortion of the current (in %).
Voltage Harmonics Screens (PM8 and PM9; TypeM2):
There are two screens. The first screen shows harmonics 3, 5 and 7

Screens with the Number of Capacitor Connections (PM12, PM13, PM14 and PM15; TypeM3):
The number of screens will depend on the number of capacitors configured. We will have a maximum of 4
screens, since the information of 3 capacitors will be shown on a single screen.
The screens are alternated automatically to show the number of connections for each capacitor (C1, C2,...up
to C12).
Flashing capacitor icons on the measurement screens:
¾The icons of the capacitors configured as ON (forced connection) will be turned off for 1 second
every 4 seconds.
¾The icons of the capacitors configured as OFF (forced disconnection) will be turned on for 1 second
every 4 seconds.
¾The icons of the capacitors that have been cancelled by the leakage current alarm will flash every
second.
¾In the case of the disconnection after changing to the setup screen or due to a leakage alarm, only
the steps connected will start flashing every second.
