Operating Modes; Main Menu - LOVATO ELECTRIC DCRG8 Manual Operativo

– Then the display will show a window asking to set the CT primary value, which usually is the responsibility of the end-installer/user. Even in this case, it
activates a direct access to the setting of the relevant parameter P02.01.
– The above-given procedure will be repeated every time the device is powered up until the CT primary value is set in parameter P02.01.

OPERATING MODES

The correctly selected mode is displayed in reverse at the centre of the home page. There are three possible operating modes, listed below:
TEST Mode
– When the controller is brand new and has never been programmed, it automatically enters in TEST mode that allows the installer to manually activate the
individual relay outputs, so the correct wiring of the panel can be checked.
– The activation and deactivation of the outputs are done as per manual mode, but without considering the reconnection time.
– Once in programming and with parameters set, the controller automatically exits the test mode.
– If you need to enter TEST mode after programming the unit, use the appropriate command in the commands menu.
MAN Mode
– When the controller is in manual mode, you can select one of the steps and manually connect or disconnect it.
– From the main page, press ►. Step No. 1 is highlighted by a box. To select the step you want, press ◄ or ►.
– Press ▲ to connect or ▼ to disconnect the selected step.
– If the number above the step is light grey, it means the step is not available because its reconnection time has not elapsed yet. In this case, by sending a
close command, 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 power returns, the original state of the steps is restored.
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 rating 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 by flashing (above) their identification number. The flashing can be prolonged
when the insertion of a step is not possible due to the reconnection time (discharge time of the capacitor).
– If the number above the step is light grey, this means the step is not available because its reconnection time is not elapsed yet. The device then waits for the
end of the reconnection time.

MAIN MENU

– The main menu is made up of a group of graphic icons (shortcuts) that allow rapid access to measurements and settings.
