•
AUTOMATIC working
This is the standard condition when switching on the regulator. When the network is inductive (motors,
transformers, fluorescent lamps, etc.), the red led _∩∩∩_ is on and the regulator begins to connect capacitors
banks.
If too many capacitor banks are connected, the red led –– will be on and the regulator will begin to switch off
banks. The preset PF value will be achieved when both Led's _∩∩∩_ and –– are off.
•
MANUAL working
Press button . When the regulator is in the manual mode the red Led on the button will be on. In manual
mode, the regulator will not operate without an external control (both inductive and capacitive Led's are off). By
pressing either the "+" or "-" buttons all banks will be connected or disconnected one step at a time. Each button
must be pressed for at least 25 secs. Operating banks will be shown by the red Led's corresponding to numbers 1
- 2 - 3 ..... When a power loss occurs, all capacitor banks will be switched off automatically. When the power
returns, the regulator will again insert all banks step by step.

5. DIGITAL DISPLAY

It is possible to read the values of PF, VOLTAGE, CURRENT and TEMPERATURE ° C on the digital display. T he
current value should be multiplied by the CT ratio to determine the actual load current. The TEMPERATURE
reading is as measured at the point of external control by the sensor - MPR8 range only.
Select
Pressing the button it will cycle around the options. On power up PF is displayed automatically
The "-" led near the two numbers display is illuminate if the P.F. value is more than 1.00.
6. SETTINGS ON REGULATOR
After making the required connections to the regulator, the following adjustments should be made.
Note: In the presence of alarms, the settings mode is forbidden.
