SW4024 - dropped of XANBUS

fasterskii

Hi there,

I have small battery backup system running SW4024 with COMBOX and SCP. I had an issue with COMBOX where LAN port stopped working (replaced under warranty). When I received the replacement and plugged it back in I have noticed that there is not data for SW. Then I have checked the SCP and it can't see it either. In COMBOX I can see the SCP. Checked the wiring and end terminators. Used new cables as well.

I tried powering off the SW for 1 hour with DC AND AC disconnected (via breakers) . Still no go. The SW seems to be working fine and no error light is lit. It is working off the batteries (when AC is shut off) and seem to be charging them as it was setup while back.

Any ideas what to do to get it back on the XANBUS and be able to access its data?

you have the proper termination resistor plugs at each end of the Xanbus - right ?

I am curious on how you got warranty for combox? 

 Unless you were one of the last people who bought combox, it has been out of support longer than when they were last sold by Schneider.

The other thing, who did the warranty replacement?  It is common for people to think that the Freedom series from xantrex (combox) is the same as the Schneider CSW and XW series. They are different animals and do not work correctly when mixed up. They look the same

Last thing, when you powered down, you did turn-off any solar correct? Does SCP work with combox out of network? Use your old cables again also.

I'm using the terminator endpoints. Tried different configurations removing and adding components but in any event the SW is nowhere to be seen.

I have tried old and new cables.

@Dave

I purchased the COMBOX this April (got a smoking deal on it as well). So they replaced it after i opened a case with support. We troubleshooted and got it replaced.

I did not see a response to some of the questions. If you do not answer them all, I go do something else, like go outside and watch the red flag wind blow. 70 knots up above me with 2 to 7 percent humidity.

@Dave

You are funny guy .

I have definitely got the right COMBOX. I'm running all newer 2016 and up equipment. No solar in this install yet. Just a battery backup for essentials when power goes out. Wired for generator support but manual transfer switch and manual setup for generator. I used the old and new cables no difference. When I connect only scp and combox with proper terminators combox can see scp. I dont think the SCP will see COMBOX (by design).

The replacement was straight from Schneider. Direct shipment. First class service, kudos to Schneider.

I hope i answered all the questions.

Is it possible that the SW XANBUS is somehow defective? Does this ever happen ?

Dave Angelini

That is where I am going,  defective network electronics in CSW. On an older unit, this happens from not having surge protection.

However as a funny guy, I missed your answer to 

Does scp see csw with combox out of network? If not, and you have let it sit for a day without the battery connected, I would say a gen surge or grid surge has damaged the network electronics in CSW. You need SPD's for battery and AC on modern inverter/chargers.

So when i take out the COMBOX out of the network the SCP does not see the SW. When I take the SCP out of the network and put the COMBOX on the network the COMBOX does not see the SW.

I have turned the DC and AC off for over an hour.

So I can assume the SW network (XANBUS) is damaged. So as long as i dont have to reconfigure it it is all good?

I loose all the real time monitoring and ability to reprogram for other batteries when replacing them eventually? There is no way to reprogram outside of XANBUS?

It was purchased in 2016, so no warranty. Does anyone repair those  units?

fasterskii

is there any way to reset the SW in hopes the XANBUS will come back?

Dave Angelini

The only thing you can do is let it sit for half a day or more off. I have seen a unit that was off for a week come back. Make sure there is zero volts DC on the battery terminals of CSW. 
 It probably was zapped if you do not have SPD's on AC and DC. This is a common problem on DIY to not use SPD's. You probably will never make that mistake again! Good Luck!
