A start-up screen will be displayed when the computer MAX 6f V12dc is
powered, showing the unit's version. This information must be included when
reporting any fault or defect
1.3 Definitions
The following definitions may be useful to understand some of the sections in this manual
1.3.1 4-Quadrant Regulator.
The regulator is capable of performing the measurement and regulation functions when the active power
is transferred from the mains to the loads (common case in a consumer installation) or when the load is
transferred to the mains (in the case of installations with generators that not only allow the consumption of
energy, but can also export or sell energy).
1.3.2 FCP System (FAST Computerized Program).
This system controls the connection sequence of the different stages, tending to minimise the number of
operations and matching the usage times of the different stages to achieve the determined final power
demand. The operations are carried out in such a way that, in the case of stages with an identical power,
the stage that has been disconnected the longest is connected when there is demand and the stage that
has been connected the longest is disconnected in the case of a surplus.
1.3.3 Stages and Steps
A distinction must be established between stages and steps. In this manual, a STAGE is described as the
capacitor banks in which the power factor compensation unit is divided and that may have different power
ratings, usually in 1:1, 1:2, 1:2:4, etc. ratios.
A step is each one of the total power fractions that can be regulated by using stages with different
weights.
1.3.4 Regulation Program.
The power ratings of the different groups or stages usually follow certain patterns called "programs”. The
program indicates the power ratios between different stages. The most frequent programs are:

or 60 Hz indifferently
