AUT
MODE
In automatic mode, the controller calculates the optimum configuration of capacitor steps in order to reach the set cos
.
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 (
kvar) higher than 50% of the smallest step, and the measured cos
is different from the
setpoint.

MEASURES
The RPC 5LGA controller provides a set of measurements displayed on the alphanumeric display, in conjunction with the
current cos
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 cos
, acting on the same value set with P.19. Below is a table with the measurements
displayed.
