!
Procedures of installation, configuration, calibration and verification must be
performed by qualified personnel only and aware of risks involved when
handling electric equipment.

6.1 CONNECTIONS:

E1/E2: Sensing voltage, selectable through dip switch SW2;
E3/4: Power Input Voltage and single-phase sensing voltage common connection;
3:Power Input Voltage;
F+: Positive Exciter Field of the alternator;
F-: Negative Exciter Field of the alternator;
6 and 7: Remote Voltage Adjustment potentiometer (1K x 3W, optional, not supplied with the
regulator. In case it is not used, short-circuit these terminals).
6.2 POTENTIOMETERS:
VOLT: Voltage adjustment. Turning clockwise increases the voltage;
U/F: Fine U/F trigger adjustment. Turning clockwise increases the actuation point;
STAB: Stability adjustment. Turning clockwise increases the stability but the response time to load
variation is slower.

6.3 DIP SWITCHES:

SW1: Operation Frequency Selection;
SW2: E1/E2 Sensing Voltage Selection. ON: 150~300Vac OFF: 300~600Vac;
NOTE
The potentiometers STAB and U / F are preset and sealed. If adjustments are
required, follow the procedures described in this manual.
