    linked for normal operation.
2. p2,p3 : external power input terminals.
3. 3,2 : sensing input terminals.
4. 1,2 : external vr terminals. linked for useless.
5. x,xx : x connect to field (+), xx connect to field (-).
6. s1,s2 : droop ct input terminal.
7. a1,a2 : var/pf controller input.
8. a,b,c : link a,c for under 90kw.
               link b,c for 90 ~ 550kw.
               link a,b for over 550kw.
9. j1~j8 : jump select terminals, 2-3,4-5,6-7.
    please refer to figure 2 and figure 3.

3. adjustment

3.1 voltage adjustment

the generator output voltage can be altered by
adjustment of the volt vr on the avr board, or by
the external trimmer (1kw) if fitted.

1. the terminals 1&2 must be linked if no hand
    trimmer.
2. before start the generator, please turn the volt
    trimmer on the avr board fully anticlockwise
    turn the external trimmer to midway position.
3. turn the stability trimmer on the avr board to
    midway position.
4. connect a voltmeter to generator output voltage
    terminals.
5. start generator set and run on no load at nominal
    frequency 50 ~ 53hz or 60~63hz.
6. if the red led is illuminated, refer to the under
    frequency roll off adjustment.
7. carefully turn volt trimmer clockwise until rated
    voltage is reached.
