I had to shut down my system to add an MPPT. Turned off the REC, and opened my main disconnect. Went to start it up, and I got an error 10.
I have checked all connections and fuses, including the six internal fuses. And all are good. I have cell voltage at the REC plug as well.
Yesterday, I was able to connect with my laptop using the software, and see the cell voltages. I was going back in to try and check RAZL last night, and now I can\'t even get the REC to show present in the software. If the RAZL setting is low, that may very well be my original issue, but now I can\'t get connected to find out...
When I hook up the USB, it sounds the tone, and I can see it on the device manager. I select the proper comm port in the \"communication properties\", but it still won\'t show present.
Was emailing tech on this because I couldn\'t get an account in here, but now I\'m in here.
I am extremely frustrated with this very expensive piece of equipment that now won\'t let me even turn my lights on.
Any ideas??
Bret, I cant find your order in our system so I dont know the details of what your have.
Did you try disconnecting the MPPT to see if the error goes away?
Are you setting your addresses to 0 and 2 for an active BMS?

Rick,
I bought my REC from them before you guys were selling them. This has been in service for a while. I am desperate for help, so I was searching and found your forum. If you can\'t help me, I understand.
If you can, my setup is a REC Active controlling an entire Victron set of components via a Cerbo. Everything is down, and the contactors are open because I couldn\'t get the REC to start back up after doing the wiring work. I got an error 10 immediately. I think that, as your tech pointed out, my cells may have settled a bit further apart than the RAZL setting after being shutdown for several days. But, I can\'t even get in now to find out. I appreciate any help you can provide, as my 5th wheel camper is dead until I get this straightened out.
Here is a screenshot I emailed your tech yesterday of my cell voltages. I didn\'t do anything after being connected except shut off the beeping BMS. When I turned it back on, I was unable to get \"present\".
I wonder if when you powered off your BMS while communicating if that caused a driver problem or something.
I assume you have removed your USB cable and rebooted, then re-installed your cable during your testing?
Yes, I have removed the USB cable and tried both ports. I have rebooted multiple times. I even uninstalled the REC software and reinstalled it. I would think if it was a driver problem, it wouldn\'t connect up to the comm port or chime when I plug in the USB.
Can the BMS firmware or anything else be hard pushed to it somehow? I would think something like that would require it sent in to somewhere.
I\'m starting to think this thing is bricked, and I will be buying a new unit...
It was starting to sound like that was one of the issues.
We sell the software and cable at our online store .
You may also want to consider grabbing a replacement BMS only. Its not too expensive and if you find that was the problem, you can have your old one fixed by REC directly and keep it for a spare. The default profile should get you up and going.
If you decide to go that way here is a cart link for you that includes a bare BMS, and USB config cable with software:

It looks like we currently have stock but Covid and the Ukraine war are delaying production again.
