Aut Mode; Measures - ITALFARAD PFC144evo Manuel De Fonctionnement


In automatic mode, the controller calculates the optimum configuration of capacitor steps in order to reach the set
cosø.

The selection criteria takes into account many variables such as: the power of each step, the number of operations,
the total time of use, the reconnection time, etc.

The controller displays the imminent connection or disconnection of the steps with the flashing of their
identification number (left). The flashing can last in cases in which the insertion of a step is not possible due to the
reconnection time (discharge time of the capacitor).

The device initiates automatic corrections when there is an average reactive power request (delta-kvar) higher
than 50% of the smallest step, and the measured cosø is different from the setpoint.

The PFC144evo controller provides a set of measurements displayed on the alphanumeric display, in conjunction
with the current cosø that is always displayed on the main display.

Press the key to scroll through the measures in rotation.

After 30 seconds without pressing any buttons, the display automatically returns to the default measurement
defined by P.47.

If P.47 is set on the ROT, then the measures rotate automatically every 5 seconds.

At the bottom of the list of measures it is possible to set the setpoint of the cosø, acting on the same value set with
P.19.

Below is a table with the measurements displayed.
