6�- CONFIGURATION
6.1.- CONFIGURABLE PARAMETERS
In order to adapt the regulator to the loads, certain parameters of the Computer MAX must be
set-up. The programmable parameters, the required settings and the set-up procedure are ex-
plained here below. See also paragraph
“5.5.2.- KEY FUNCTIONS IN SET-UP STATUS”
to see
how to select the different menu options.
The configurable parameters are listed and shortly explained below.
6�1�1�- PLUG&PLAY FUNCTION
To access the Plug&Play screen, press the buttons to open the following screen:
Press to start the process; if you want to stop the process, long , and it will return to its initial
state.
Once started, the digits will start flashing and the device will start a capacitor measurement,
calculation and connection and disconnection process to gather the following capacitor bank
parameters:
Phase (
“6.1.8.- U, I PHASE ANGLE SETTING.”
)
y
C/K Factor (
“6.1.3.- SMALLER
AVAILABLE CAPACITOR STEP”
) .
Once the device’s Plug&Play process has finished and no error has occurred during the pro -
cess, the calculated C/K factor and the measured cosine phi will be displayed on the screen,
the result of having correctly configured the phase relationships (2 times each).
If an error occurs during the process, the following screen will appear:
Conditions for the correct operation of the Plug&Play function:

The system should be maintained with an inductive cosine of 0.62 to 0.99 throughout the
process.

The power in the system should be stable. Any major load changes (>10 % in less than 20
seconds) would result in an incorrect calculation of the capacitor power ratings.

There must be enough current in the system at the regulator’s input, i.e., >100 mA AC.

If the load is unbalanced, the correct operation of the Plug&Play function will depend on the
phase to which the current transformer is connected.

The correct values for Program (
“6.1.5.- STAGE’S CONFIGURATION OF PF CORRECTION
EQUIPMENT (CONFIGURATION PROGRAM)”
) and Number of steps (
“6.1.7.- SELECTION OF
THE NUMBER OF STAGES”
) must be configured beforehand.
