2 Power factor regulator PR-7D and PR-7D12 series permit the visualization on a digital display of power system cos ϕ, and the automatic connection of capacitors in function of this cos ϕ. Cos ϕ C/K Setting Operation Program Setting Delay time for switching on/off operations setting Capacitors steps setting Manual Mode Cursor keys (Conection/Manual Disconnection) Setup Key SETUP Setup key: - Long press To enter and exit Setup. - Short press: To move from display mode/editing mode. Cursores: - Cursors to move within the screens in display mode or to edit parameter in edit mode. Visualization / Edition: Simbol showing which parameter is being displayed/edited. Long press of the Setup key for (more than 1 seconds) accesses the adjustment screens if all the capacitors are disconnected, otherwise stars disconnection sequense and then accesses to setup menu. If any key is not pressed in 12 seconds, the equipment leaves the SETUP. Screen 1. Editing Cos ϕ 0.85L to -0.95C (2 quadrants) Screen 2. Adjusting reactive current C/K. Ratio 1 st step.
