6048 slave not turning on

ArtboardArtboard Registered Users Posts: 22 ✭✭
Schneider 6048 slave will not switch on after maintenance off. Switched system off to replace 2 batteries. Master comes on, slave will not turn on at all. I used to be able to change the sequence of turning the DC breakers back on to get the slave to switch back on, but no joy on any combination now. Running off just one 6048 causes long generator run times to recharge, cannot equalize at all.  Help?

    Do you have the Xantrex distribution panel? Did you disconnect DC for at least three minutes from the XW before you connected DC? 

    One of the problems with generators is they can glitch an XW and with old firmware the unit can be "bricked"
    Bricked is dead to the world without the config tool or a combox. Depending on your skill you can fix this without sending the unit for a ride.

    The other thing is that the XW is fried. Any funny smell from the power bridge on the right side?

    Are you the installer or is there anyone you can call near La Veta?

    Other bad news, Apollo is long gone out of business.  Why can't you EQ with the good unit by disconnecting strings?

    Good Luck!

    DC has been disconnected from slave 6048 for hours. Still does not turn on. I have Xantrex SCP (system control panel). No funny smells from unit. T80s still work, so no need to replace. Yes, I have become installer by default and OJT. Replaced 29 of 32 batteries since system online in Jan ‘09. Always had trouble restarting slave 6048 unit, but this time is longest offline. How do I get a config or combox?

    Could be firmware. Are you computer savvy or have you ever done firmware? It is not for everyone!
    I would call Schneider tomorrow and see what they will do. Get the firmware  version of the working XW from your SCP. Assume the bad one is the same date? One of the reasons I asked if you had the XW distribution panel was to get an idea of the quality of the installation?

    The store here sells the gear.

    I sell to my clients only but check what Schneider says.

    Silly question perhaps, but have you confirmed dc voltage at the dc input terminals of the slave with a meter?
    Off-grid.

    I don't think it is silly!  That is why I asked him (never heard an answer) if he had the Xantrex pwr distribution panel. He said he had trouble before restarting the slave, which did not sound good either. 

    Anyone reading this should be advised that the older gear can be bricked from grid and generator glitches. This has been made much easier now if you have the latest firmware in your COMBOX. Even if you are not computer savvy Schneider can walk you through it if your gear has warranty. If you are one of their install people they will help you forever on any of their XW systems.

    The older XW's that do not have the grid or a generator just keep running like the eveready bunny :)  Lightning strike exception though..
