OPERATING MODES
The currently selected mode is displayed in reverse at the center of the home page. There are three possible operating modes,
listed below:
4.1
Manual mode (MAN)
When the unit is brand new and has never been programmed, it automatically enters in MAN mode.
When the unit is in manual mode, you can select one of the steps and manually connect or disconnect it, after necessary regulator
parameters set-up.
From the home page, press ►. The step No. 1 is highlighted by a box. To select the step you want, press the ◄ and ►.
Press ▲ or ▼ to enter to disconnect the selected step.
If the number above step is light gray, it means that the step is not available because its reconnection time is not yet exhausted.
In this case, sending a command to close the step number will flash to indicate that the operation has been confirmed and will be
conducted as soon as possible. The manual configuration of steps is maintained even in the absence of supply voltage. When the
power returns, the original state of the steps is restored.
4.2
Automatic mode (AUT)
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.
