MANUAL working
Press the button “SETUP”.
When the regulator is in the manual mode the red Led on the button will be on. In manual mode, the
regulator will not operate without a manual input (both inductive and capacitive Led's are off). By pressing
either the "+" or "-" buttons all banks will be connected or disconnected one step at a time. Each button must
be pressed for at least 25 secs. When a power loss occurs, all capacitor banks will be switched off
automatically. When the power returns, the regulator will again insert all required banks step by step.
SETTINGS ON REGULATOR
After making the required connections to the regulator, the following adjustments should be made.
Note: In the presence of alarms, the setting mode is disabled.

C/K setting
By pressing the “SETUP” button for 4 secs in AUTOMATIC mode, the "SETTING MODE" will be entered.
The red led "Ind” and “Cap” will illuminate and, at the same time, a number will appear in the digital
display. Release the “SETUP” button and use the " + " or "-" buttons to change the selection. The
suggested value to set is given on the table "C/K VALUES" (see table on the next page).


When using the regulator on 220/240 Vac networks the C/K values should be doubled.

“-” means installation of C.T. with primary value too small.

PF setting
After setting the C/K value, press the “SETUP” button again for 4 secs to indicate the selected PF
required. At the same the red led’s "Ind” and “Cap” will illuminate. Release the “SETUP” button and use
the " + " or "-" buttons to change the selection. A P.F. of 0.95 is recommended.

SAVING THE SET VALUES
By pressing the “SETUP” button again the C/K, P.F. values which have been selected will be saved and
the Regulator works in AUTOMATIC condition.
Note – It is not necessary to set the rated frequency, the Power Factor Regulator auto-set the mains value.
