This manual is intended as a rapid guide to the use and operation of the PFCL Elite
regulator.
Any manipulation or use of the equipment different from that specified by the
manufacturer may compromise user safety. The apparatus must be disconnected
from the power supply before carrying out any maintenance operation. In the event of
failure in the operation or the protections, the unit must be left out of service and its
reconnection must be prevented until the problem has been corrected.
2.
- Connections
A current transformer must be installed for the start-up (I
n
/ 5 A) depending on the
total current of the load.
The regulator power supply voltage will be two-phase, preferably L1 for U
L1
and
L2 for U
L2
, and the current will preferably be taken from L1. It must be supplied by
means of an automatic switch. See cable section and protections in the table of
technical features.
The current transformer must be placed in such
a way that it measures the total current of the
loads plus the capacitors.
The transformer for the leakage current must be
placed so that it measures the current in the
capacitor bank and must include lines L1, L2, L3
and N.
The unit has a switched relay exclusively for the alarm outlet.

Communications
The PFCL Elite regulators can be connected to a computer or another unit by
means of the standard RS-485 bus included. This system is able to focus data
on a single registry point (Power Studio® System).
In a network of equipment, the PFCL Elite communicates by question-answer
(slave).
The PFCL Elite communicates with the MODBUS RTU© protocol, which
enables it to access the electrical parameter and the main variables and
configurations. Contact the manufacturer for the table of addresses.
See section 4.3. to change the communications configuration.

4.- Handling and configuration
4.1.- RUN
When it is in RUN, the equipment compensates the reactive energy by connecting the
necessary capacitors. In this mode, the display can show different parameters of the
installation, depending on the screen.
By pressing the and arrows, we will move through the different measurement screens.
By pressing the arrow, the maximum values are shown, and by pressing the
minimum values are shown of the variables shown on each screen. If you want to see the
instantaneous values again, press the key or wait 5 seconds for this to happen
automatically.
In the maximum or minimum screen, these can be reset by holding down for the
maximums and for the minimums. If you hold down and in the max or min screen,
they will all be reset.

4.2.- Error and alarm codes
In the measuring screens there may be different error or alarm codes making the screen
backlight flash. The meaning of each of the codes is summed up in the following table:
ERROR
message Description
No current . Load current below minimum or current transformer not
connected. It appears if the secondary current < 50 mA.
On compensation. The unit measures capacitative power and all steps are
disconnected.
Sub-compensation. The unit measures inductive power and all steps are
disconnected.
Over-current. The measured current exceeds the nominal current by +20 %.
The nominal current is considered to be that of the primary of the TC.
Overvoltage The measured voltage exceeds the nominal voltage by +15 %.
Low voltage. The voltage in some of the phases is under 90% of the nominal.
THD alarmU. The THDUlevels are higher than those configured in the THDU
alarm.
THD alarmI. The THDI levels are higher than those configured in the THDI
alarm.
Leakage Alarm. The leakage current is higher than that configured in the
leakage current alarm.
Cosine Alarm ϕ. The ϕcosine is out of the range configured in the Cosine
alarm ϕ.
Temperature Alarm. The measured temperature is higher than that configured
in the Temperature alarm.
Repeated Leakage Alarm. Leakage has been detected in the system, but the
cause has not been found.
Leakage Alarm in Capacitors. Leakage has been detected that is caused by
one of the capacitors and this capacitor is disabled. The disabled capacitors
are shown flashing. To enable them once more, see the Leakage Alarm
configuration in section 4.4.
Leakage current transformer not connected alarm (if the leakage alarm is
enabled).
4.3.- AUTO-TEST
The equipment allows a self-test to be made for maintenance of the capacitors, by
connecting them individually and measuring connected power and leakage current. Tp
perform the self-test, the unit must be in the SETUP screens and must be pressed
for a few seconds at the same time. In the AUTO-TEST screen, the and keys show
the data of each capacitor. To start the process, press and hold down . The load must be
stable during the process. To leave SETUP, press and for a few seconds together,
or press and hold down to go to the checking screen. Further information on the AUTO-
TEST in manual.
4.4.- SETUP
In SETUP the and keys are used to move through the different screens and see the
configurable parameters of the equipment.
To edit some parameter, press the key to enter edition mode and the parameter to be
edited will flash. Then the or keys will be used to increase or decrease the value, and
the or keys to change the editable parameter. Once the screen parameters have
been configured, press to confirm and leave the edition mode.
P&P (PLUG AND PLAY): To start the process, press and hold down . The P&P
automatically adjusts the PHASE, C/K, PROG and STEPS parameters in a step
connection process. After the measured cosine (confirmation of the chosen PHASE) and
the configuration made. For correct operation the load must be inductive, with cos phi > 0.5
and stable (variation < 10%). If the program is not standard, the P&P starts with (long).
After the P&P, the primary of the TC has to be configured (IP screen) for the equipment to
measure the current and the powers correctly. Further information on Plug&Play in manual.
IP: The current of the installed transformer primary is configured bearing in mind that the
current secondary is always 5 A. Range of values between 5 and 9999.
COS: Configuration of cosine phi to be reached and its type (inductive or capacitive
). Range of values between 0.70 and 1.00.
PHASE: Phase configuration depending on how the current transformer has been
connected. The cosine phi is also shown to check the correct phase, it being understood
that in a normal installation, it must be between 0.60 ind and 0.99 cap.

For network voltages other than 400 V, the result of the table must be multiplied by Unetwork /
400. C/K can be calculated with the following expressions:
Example calculation of C/K
: TC ratio = 500/5 ; 1st capacitor: 60 kvar , 440 Vac.
It = Current of the TC primary; Ic = Current of the first capacitor

PROG: This configuration depends on the ratio of kvar between the different steps with
respect to the first. For example 10+20+20+20 kvar would be program 1222. If it is not a
standard programme, choose OPEn and configure any programme between 1111 and
1999.
STEPS: Configuration of the number of steps of the battery.
DELAY: Configuration of the connection time between steps (seconds). Range of values
from 4 to 999 s. The reclosing system time is 5 times the DELAY.
COMM: Baud Rate (9600 - 19200 - 38400), parity (none-odd-even), number of stop bits (1
or 2) and number of peripherals (1-255).
ALARM: alarm enabling (on-off) and the possibility of their triggering the alarm relay (yes-
no). With the and keys, the different alarms are displayed.
ALARM COS: The cosine limit value and type (inductive or capacitive ) under
which the alarm would be triggered (E10) are configured. A minimum value is also
configured for the current needed to make the cosine alarm come on.
ALARM THD: The alarm limit values are configured as a % above which the THDUand/or
THDI(E07 and E08) would be triggered. A step must be connected for a THD alarm to be
triggered.
ALARM ILEAK: The alarm limit value is configured in mA above which the leakage current
would be triggered (E09). The option to search for faulty capacitors when E09 (Off-On) has
been triggered is also configured. If there are capacitors annulled by this alarm, the reset
option appears (yes-no).
ALARM TEMP: Limit value for the temperature alarm (E11) in ºC.
On/Off/Auto: The state of the battery capacitors is configured (On: Always connected, Off:
always disconnected, and Auto: the regulator decides when to turn it on or off). With the
and keys, the different capacitors are displayed.
DISPLAY: The luminosity of the backlight is configured as a percentage, as well as its
state (On: always alight, Off: always out, Auto: it goes out after 5 minutes if no key is
pressed).
