5.3.- TARGET COS φ
The cos φ makes it possible to define the power
factor required for the installation. The Controller
MASTER control VAR FAST 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 congured, depending on the status of the digital inputs (See “4�7�-
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.
Press the key to enter editing mode. It is identified by the symbol and the blinking
of the digits to be modified.
The key increases the digit value or shows the next option.
The key decreases the digit value or shows the next option.
The key skips to the previous digit.
The key skips to the next digit.
Press to validate the data; the symbol disappears from the display.
Maximum value: 1.00.
Minimum value: 0.80.
If the value entered is lower than the minimum value or higher than the maximum value,
the backlight of the display ashes and the value entered is replaced with the minimum or
maximum value, or with the last value validated.
Press key to access the next programming step.
If no keys are pressed for 5 minutes, the unit switches to the simulation screen, “5.27.-
SIMULATION SCREEN”.
