5.1. MAN and AUT Modes
• The icons AUT and MAN indicate the operating mode automatic or manual.
• To change the mode, press and hold the
• The operating mode remains stored even after removing and reapplying the power supply voltage.
5.2. MAN Mode
• When the unit is in manual mode, you can select one of the steps and manually connected or disconnect it.
• In addition to the specific icon, the alphanumeric display shows MAN in order to highlight the manual mode condition.
Press to view the other measurements as usual.
MODE
• While the display shows MAN, it is possible to select the step to be switched on or off. To select a step, use the ▲or
▼buttons. The selected step will flash quickly.
• Press to activate or deactivate the selected step.
MODE
• If the selected step has not yet exhausted the reconnection time, the
been accepted and will be conducted as soon as possible.
Manual configuration of the steps is maintained even when the power supply voltage is removed. When the power returns,
•
the original state of the steps is restored.
5.3. AUT Mode
• In automatic mode, the controller calculates the optimum configuration of capacitor steps in order to reach the set cosϕ.
• 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 cosϕ is different from the setpoint.

6. Measures

• The RPC 5LGA controller provides a set of measurements displayed on the alphanumeric display, in conjunction with the
current cosϕ that is always displayed on the main display.
• Press the key to scroll through the measures in rotation.
MODE
• 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 cosϕ, acting on the same value set with P.19.
Below is a table with the measurements displayed.
