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 edit mode and vice versa.
If no key is pushed 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, cos, etc.) The displayed parameter is pointed by the sign
By default the regulator displays the cos, but pushing the keys
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 in maximum values screen causes de deletion of recorded
max values, in other parameters visualization screens we will go to SETUP
screens.

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. The program P00 of simulation allows to see on screen the steps
that it would connect without managing to do it.

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 cos is between 0.7 Ind and 0.98 Cap.

4.4.- Selecting the rated primary current of CT
If the LED is blinking indicates that we are in SETUP mode and
adjusting primary CT current. When in RUN mode or when Iprimary is displayed,
the LED indicates whether the displayed current has a scale factor x1 (LED OFF)
or x10 (LED ON)
