To switch between AUTOMATIC and MANUAL mode, press
the
MAN/AUT
button for 5 secs.
To switch ON or OFF a bank manually, press
MAN/AUT
for 5
secs. (the AUT led turns off and the MAN led lights), press
UP
or
DOWN
to select the capacitors bank desired then confirm with
SETUP
button. To verify the status of the bank selected, the power
(in kvar) appears on the display.
In the menu advanced
(“MAIN SETUP”) you configure the
compensation equipment parameters like: kvar power banks,
capacitors rating voltage, switching delay, network rating
frequency, type of network (single or 3-phase), alarm mode
relays (NC or NO).
To enter in the MAIN SETUP:
set the regulator on MANUAL mode (you should read the
PF on the display);
disconnect all the banks, press and hold the
SETUP
button
until to read PAR SETUP onto digital display: press and
hold again
SETUP
until “MAIN SETUP” is displayed.
MAIN SETUP parameters description:
POWER CAP n°
=> reactive power ratio (kvar) of each bank;
to set a bank in
FIX
mode
(always connected)
set
the power to “0,0” and press
DOWN
to read
“
FIX
” on the display.
CAP VOLTAGE
=> voltage ratio (V) of the capacitors banks
CAP RC TIME
=> switch delay time (sec.)
-----
CAUTION -----
Contact the capacitors manufacturer before modify this value.
ALARM RELAY
=>
type of output contact relay (NC, NO
or FAN mode) in alarm condition.
EXTERNAL TV =>
set the Voltage Transformer (primary
and secondary value) if used.
LINE FREQ
=>
network rating frequency (50 or 60Hz).
LINE TYPE
=>
network system (single or 3-phase).
SYSTEM MODE
=>
mesurement on 2 or 4 quadrants.
USER INTERFACE OPERATION
After the setting procedure, the PF (cos
φ
), the voltage and the
current measured appears on the display: you can read the
reactive power needed to obtain the target cos
φ
chosen.
In AUTOMATIC mode, pressing the
SETUP
button you can
navigate between the pages in the sequence below :
MAIN
→
THD
→

MAIN =>
network parameters measurements including :
cos

, true RMS voltage, true RMS current,
Delta Power (means the reactive power gap to
target the SET cos
φ
)
THD =>
total THD% current value, fundamental

and
harmonic

value
measurement
FAN =>
real time temperature measured by the probe
(if connected) in °C
SET cos

=>
target P.F. (cos
φ
): in ATUOMATIC mode
you can just check it, in MANUAL mode you
can set the value by
UP
and
DOWN
buttons
POWER =>
Active and Reactive Power measurments
MAX(line) =>
max values of network parameter measured
(2)
MAX(power) =>
max network energy values measured

Note:if the POWER FACTOR value on the display is not stable,
reverse the K-L (C.T. signal) connections.

All the history measurements can be reset by pressing the
UP
and
DOWN
buttons at same time.
The display of the parameter is 30sec., after this time the regulator
come back to the main display page.
During the manual control of the banks, the AUTOMATIC
control is inhibited but the others control are operating
(measurements and alarms). Moreover, if the voltage supply is
interrupted, the bank status set in MANUAL mode is stored in a
non-volatile memory: when the voltage supply is restored, the
regulator switches in the memorised banks.
ALARMS:
The output relay <C1>-<C2> (see settings of the
ALARM RELAY contact), switches when any of following
conditions occur:
HIGH VOLTAGE
: the voltage measured to the <L2>-<L3>
terminals exceeds the 110%Un for 15 min.; the alarm
relay operates in the programmed mode.
LOW VOLTAGE
: the voltage supply is less than 85%Un; and
the alarm relay operates in the programmed mode.
HIGH CURRENT
: the current measured from the C.T.
exceeds the 110% In. the alarm relay operates in the
programmed mode.
LOW CURRENT
: the current measured from the C.T. is less
than 6%In for 5secs.: if this conditions during more than
2 min. the regulator switch OFF all the capacitors banks,
and the alarm relay operates in the programmed mode.
UNDER COMPENS
: this alarm appears when the PFC
equipment does not reach the target cos
φ
for 15min;
and the alarm relay operates in the programmed mode.
OVER COMPENS
: this alarm appears when the cos
φ
is
Capacitive for 2 min; the regulator switches OFF all the
capacitors banks and the alarm relay operates in the
programmed mode.
HIGH THD%
: the harmonic distortion value is more than the
THERM THD% value set on the PAR SETUP menu; the
regulator switches OFF all the banks and the alarm relay
operates in the programmed mode.
OVER THD%
: the harmonic distortion value is over the
instantaneous OVER THD% value set on the PAR
SETUP menu; the regulator switches OFF all the banks
and the alarm relay operates in the programmed mode.
OVER TEMPERATURE
: the temperature measured by the
probe (if connected) is over the value set in the PAR
SETUP menu the regulator switches OFF all the banks
and the alarm relay operates in the programmed mode.
The normal functions resume when the alarm condition ends
and the alarm relay is reset.
