<p>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).<br>

<div dir="auto">Hi all,

<div dir="auto">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???</div>
