15 AVR-A-OPT-03/C CONNECTION
15.1 CONNECTION WITH AUXILIARY COIL
Sensing Voltage 160 to 300Vac and 320 to 600Vac.
¹ Item not supplied by WEG (opened
– parallel, closed – single);
² If there is no Potentiometer connected, keep terminals short-circuited;
³ 10A/250Vac switch to turn ON/OFF the regulator;
4
JR, JS e JT Jumpers
– Sensing voltage selection (pins 1-2 = 160 to 300Vac, pins 2-3 = 320 to 600Vac).
ATTENTION
1. Before connecting the regulator to the generator, verify in the installation manual, the reference
nominal voltage.
2. The sensing voltage can be different than the alternatorphase voltage. Note the point where the
sensing voltage is taken from (middle of the phase or complete phase).
3. If the reference voltage is not equal to the output voltage of the generator,
do not
make the
connections without consulting the service department.
