3- Signals; 4- Operation - ITALFARAD RC4 Notice D'utilisation

- Manual operating
In order to insert manually the capacitor banks, move one ore more swftches, from 1 to
4, on the right (MANUAL INSERTION).
- CT orientation
For a correct operation of the regulator in every condition of load, it is necessary to
orientate the CT as follows:
1) Make sure that the load in line is 0.
2) lnsert manually all the banks of the board, by means of the relevant switches.
3) Check that, in these conditions, the led "CAP" is on. lf on the contrary the led "IND" is
on do invert the connections coming from the CT onto the terminals K and L.

STEP1-4
When you carry out a correct installation of the regulator, the led ON indicate the
presence of measuring ar¡d feeding voltage and a few seconds later the regulator
presents one of the following possibilities:
LED C/K = off
In this case the regulator doesn't insert any bank, even if the power factor value is less
than the imposed power factor.
