The cos
φ
makes it possible to define the power factor required for the installation. The

will add the number of capacitors needed to adjust the value as close as possible
to the objective value. Since the regulation is by stages, it does not perform any operations until the
uncompensated demand is at least 70 % of the power of the smallest stage or the compensation
surplus is 70 % of the power of the smallest stage.
Four target cosines can be configured, depending on the status of the digital inputs (

)
the unit allows one of the 4 programmed cosines.
For every cosine, you must program the value and state whether it is inductive
L
or capacitive
C

of the display flashes and the value entered is replaced with the minimum or maximum value, or with
the last value validated.
