I'm not sure on that particular device, but SCI equipment usually have
test points, that you measure with a volt meter: positive to test point,
negative to the negative battery input. The readings reflect cell
voltage, so you need to figure the voltage set points you want, and
divide by 36 (in your case) to determine the proper set points. Turn the
little pot, and watch the values change by the thousandth. Just to make
things interesting, those set points can drift. Overall, SCI made great
gear, I have a bunch of it still in service. They kind of got run out by
Chinese copies of their circuits that sold for significantly less.
Another option is Midnite Classics can be set to 72 v mode (I believe).

Hi all,
I am servicing a system that has a 72 volt charge controller circuit
board made by solar converters in Canada. I believe they are no
longer in the business. The float and bulk settings are messed up and
they are set with two variable resistor pots. Can anyone tell me how
I can set these???
Thanks,
Kris
