What caused the diodes to burn out?
Field power is fed through F1 and F2 - these are clearly marked on the AVR.You simply have two AC leads for output voltage sensing (7 and 8 ) and two field leads for changing the exciter field strength (F1 and F2). That should be all that is needed for the control. I did not mention the setup procedure... normally have to adjust AVR voltage pot for proper output range as well. If you need the Stamford docs you have to look at the Cummins web site, they now own NewAge AVK Stamford.dieselgman[/quote ] Thanks for the replies guys.It all helps but i need a bit more selective info I understand that F1 and F2 are for the exiter leads but which lead goes to F 1 , the + or the - or will either do?And which of the phase leads go to 7 or 8 or do i hook op 1 phase to 7 and the second phase to 8 or do i use 1 phase and neutral?The document that came with the AVR mentions the procedure for adjustment of voltage and amperage and hertz selection but not much else.
