The microprocessor electronic control is made on a standard RACK container with 4 electronic board in EURO standard and connected to the system by means of a pcb and plug connectors on the back side of the container. The four pull-out boards have the following functions:

¥ POWER board with d.c. stabilized power supply;
¥ MAIN board (CPU) with the microprocessor for the management and the control of the different functions of the regulator and of the timer;
¥ DRIVERS board for the control of the voltage variatiors motors;
¥ SERVICE board with transformers for the continuous monitoring of the input/output voltage levels.

On the panel of the RACK there are the membrane keypad for the programming of the different functions, the liquid crystal display, the control leds, the main switch, the switch for the manual command of the reduction and the RS232 connector for the remote control.
The internal timer allows the programming of 4 different cycles of reduction during the 24h, is also present a device that automatically by-pass the regulator in case of irregular operation. The RACK is connected to the system by means of pull-out connectors to allow the complete removing without disconnecting the screwed connections.

REGULATOR STANDARD PROGRAMMING
It is possible to display all the stored parameters by means of the keypad on the microprocessor electronic control. It is also possible to modify the programming to customize the regulator for all the specific user requirements.

The "ELIGHT" flux regulator, besides the standard mode, can have advanced functions in advanced mode "ELIGHT PLUS". In this case the regulator has the possibility to manage the lighting installation with different communication systems: on site using the keypad; or with a remote control (via radio or over the telephone network).
The management in advanced mode of the regulator and of the installation is supported by a measuring devices (multimeter) to sense and measure the following parameters:

• The voltage of the three phases;
• The line current of the three phases ;
• The power factor of the three phases;
• The total apparent power of the three phases;
• The apparent power for each phase;
• The active power of the three phases;
• The active power for each phase;
• The reactive power of the three phases;
• The reactive power for each phase;
• The consumption of total active energy;
• Hours counter of operating in regulation; Hours counter of operating in By-pass.

These parameters besides to be sensed and measured by the devices are also sent to the microprocessor electronic control.
It will use the data in the following ways:
• Displaying of the data on the LCD on the panel;
• Generating alarm thresholds for each single measure;
• Storing the sampling of the data choosing the measures;
• Giving the possibility to display the stored sampling;
• Giving the possibility to read the data using a P.C., remote control.
