Program 1:2:4 � The rated power of the second stage is twice the rated power of the first stage
and the rated power of third stage and up is 4 times the power of the first stage. For instance,
a 5-stage device of 300 kvar would be formed by a first stage of 20 kvar, a second stage of 40
kvar and 3 equal stages of 80 kvar, and would be described as a device of (20 + 40 + 3 x 80)
kvar.
Other switching programs� Other switching programs are also commonly available, like
1:2:2:4 or 1:1:2:2, etc. Abbreviated designation form, as can be deduced from previous cases,
consists of a sequence of numbers giving the relationship between the different stage powers
(kvar), and the first stage power, which value is taken as device (1). The successive stages will
be designated by 1, or 2 or 4, etc. meaning that the kvar ratio of such stages with regard to first
stage are equal, twice, four times, etc.
2�3�5�- PLUG & PLAY
When a reactive energy regulator is installed, a series of parameters must be configured for its
correct operation. Some of these parameters might be hard to know, such as, for example, the
voltage phases or the voltage corresponding to the current measured, as well as the current
transformer ratio.
The computer MAX features a smart automatic process that detects the necessary parame-
ters, such as:

C/K : calculates the ratio between the current transformer and the power of the smallest
step.

Phase : identifies the phase sequence between voltages and the correspondence with
the connected current.
