Depends on the requirement for the BMS.
Usually, but not 100% always, the requirement is to get the voltage up
to "absorb" and then stop charging.
Just set the min and max times very low, like 1 minute and that should
satisfy that one.
I do not remember if the MX60 had a Re-Bulk setting but I think it did ?
The MX did not have a logic input for turning it on and off of course.
OB had a communications
device that converted their communications protocol to Modbus or
Ethernet I think it was which
may (or may not) be able to make it work.
Could always buy something newer and keep the MX60 as a spare.

boB,
Interesting...Sounds like this is not a candidate for
L-ion batteries.

Hi Bill....
As I remember, the min is of course... Minimum time in Absorb.
Max is maximum time in absorb but depended on how long it took to get
from Bulk MPPT to that Absorb voltage.
So if it took 3 hours to get to Absorb that morning and you had t set
for Max 2 hours, it would Absorb for 2 hours.
If it only took 1 and 1/2 hours to reach Absorb voltage, the MX60
would Absorb for 1 and 1/2 hours.
It worked "OK" but these days I would probably just set it for min
of some 2 or 3 hours and then a max could be the same
time or longer for FLA batteries.

Yes, the old one, not the FM. This oldie had an interesting way to
set the absorption time. You would set the "min" time (in minutes)
and you would set the "max" time (in hours, you have to set it to
1,2,3 or 4 hours).
I need to know if I set the "min" to 10 minutes and the
"max" time to one hour or two or three or four, how long will it
stay in absorb?
I called Outback and Megan there didn't know how this
old fart works, apparently tech support isn't supporting us their
old relics.
