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° => programming of each reactive power ratio
(kVAr) of each bank in the position "n" showed by means
display;
to set a bank in FIX mode (3) (always connected) set the power
to "0,0" and press again 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. PRESENT allow to
program the ratio TV and/or MT values.
LINE FREQ =>
network rating frequency (50 or 60Hz).
LINE TYPE =>
network system (single or 3-phase).
SYSTEM MODE =>
measurement on 2 or 4 quadrants.
When EXTERNAL TV is enabled it's possible to connect a voltage
transformer at mountain of the voltage signals. In this case it's
necessary to program the reduction ratio (RATIO-TV). This means
the voltage read is related to the RATIO-TV, so if this value is not
correct the regulator doesn't read the right voltage.
NOTE: the default programming is for a direct voltage measure,
without transformer.
In the case the volt metric signal is read at mountain of the MV
transformer (as previously described) and the connection of the
compensation equipment is downstream of the MV transformer, is
necessary to set up the MV/LV ratio by means the parameter
RATIO-MT. On this way it's possible to program the nominal LV
power values of each capacitor bank at LV nominal voltage.
(3): Explaining of the FIX step capacitor bank function.
To connect/disconnect the banks as FIX it's necessary repeat the
same procedure followed to switch-on a bank in MANUAL function,
note (1); and then to pass in AUTOMATIC function. On this way the
regulator uses the others capacitors banks for automatic
compensation forgetting the FIX batteries (previously programmed
in the "MAIN SETUP"). The automatic compensation is done
calculating the remaining steps not programmed as FIX banks.
Using this function is possible create a mix-system AUTOMATIC
and FIX compensation.

(4): 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 disconnecting all the
capacitors banks.
LOW VOLTAGE: the voltage supply is less than 85%Un; and the
alarm relay operates in the programmed mode.
