Any manipulation or use of the equipment out of the conditions
specified by the manufacturer may put in risk the user safety. Before
any maintenance operation the equipment must be disconnected from power
supply. In case of miss operation or protection fault the equipment must be
disconnected from supply and remain out of service ensuring against any
accidental reconnection.
1.- Regulator Connection
For proper operation it’s necessary to install a current transformer, CT
(normally In / 5 A), which primary must be sized according to the
maximum expected load current in the installation.
The regulator supply (C-D terminals) must
be taken between two
phases and the CT should be located in the third phase. See technical
characteristics for cable sizes and required protections.
Must use an switch or automatic switch for supply the regulator

3.- Four Quadrants Operation
The Controller

PFR 12
regulators operate in 4 quadrants (suitable
for imported or exported active power). For exported power, a negative
symbol is displayed in the cosϕindication. Check phase connection and
setup if there is no exported energy and the indication is not correct (see 4.3,
SET-UP - phase)

4.- SETUP AND MEASUREMENTS
To enter the SETUP mode, press the setup key (9), for more than 1s. If all the capacitors are disconnected, the access in immediate, otherwise a disconnection sequence
starts and then accesses to setup menu. In the SETUP mode, if no key is pressed for 3 minutes, the equipment exits such mode and returns to normal operation mode.
Key to access the SETUP mode:
- Long push to enter and exit SETUP mode. Also DELETE max values when
in the measuring mode
- Short push: to change from display mode to editmode and vice versa.
If no key ispushed during more than 3 minutes, the regulator exits the SETUP
mode without changing the setup.

4.1.- RUN & Measuring mode
In normal operation mode (RUN mode) the regulator display may show different
parameters (V, I, cosϕ, etc.) The displayed parameter is pointed by the sign .
By default the regulator displays the cosϕ, but pushing the keys the
following parameters can be explored: Current (I), Current harmonics (THD), Mains
Voltage (V), Maximum current (I MAX) y Maximum voltage (V MAX). If both keys
are pushed simultaneously the regulator displays the Nr of connected steps.
A long push of key when maximum values are displayed causes de deletion of
recorded max values.
4.2.- Program selection
This setting depends on the kvar ratio between the different capacitor steps. For
instance if the bank is 10+20+20+20 kvar the program is 1:2:2:2, so the option 122
must be selected.

4.3.- Selecting the CT connection phase
Choose among the options in the table depending on CT connection and the
phases where V is measured. In normal installations (no exported energy) choose
the option for which the displayed cosϕis between 0.7 Ind and 0.98 Cap.

the LED indicates whether the displayed current has a scale factor x1 (LED OFF)
or x10 (LED ON)
