[RE-wrenches] Battery question

[Kristopher Schmid]

Greetings All,

I have inherited a stand alone system at a state park originally installed
by Currin Corporation out of Michigan (I think that he did work in a number
of state parks in the region).  Good install, but the custom designed 72
volt controller (a Canadian company that slips my mind at the moment)
crapped out.  I replaced it with a 72 volt midnite controller and all is
well except...
The original system used a dc relay to disconnect the 72 volt dc
submersible well pump.  I kept the relay in the circuit controlled by the
midnite aux port.  Since I was unable to read any programming from the old
controller, I am not sure where to set the cut-in and cut-out voltages for
the pump relay.
Battery bank: 12 Deka MK 8G27 (72 volts, 176 ah)
Pump current: unknown at the moment

Anyone?

Thanks,
Kris
