Automatic Voltage Regulator – AVR-A-OPT-06 l 21
¹ Item not supplied by WEG, please verify ratio specification (PAR/1 or PAR/5);
² if there is no Potentiometer connected, keep terminals short circuited;
³ 10A/250Vac switch to turn ON /OFF the regulator (Item not supplied by WEG)
* Output line voltage from alternator in accordance to sensing class and the voltage level of the regulator power supply
(Table 4.1).
ATTENTION
1. Before connecting the regulator to the alternator, verify in the installation manual, the reference nominal
voltage.
2. When using an auxiliary coil, the connector E3/4, reference of the regulator circuit, should be the
mandatory common point between the coil and the alternator
3. If the reference voltage is not equal to the output voltage of the alternator, do not make the connections
without consulting the service department.
