Schaudt Booster D+ and Orion XS

[Alanf75]

Sorry if this has been covered before, I suspect it has!
I"be fitted my Fogstar drift 300ah lithium and my Orion XS. I also have a Schaudt Booster installed from factory. I've removed the 50a fuse from the starter battery to EBL so as not to run with the split charge in the EBL active. I've took a link off the D+ to the Schaudt to Run to the he Orion XS.
The problem I'm having is that the Orion is not activating when the engine is started. I think the Schaudt isn't charging either as the 50 amp fuse is out and it's in combination with the EBL. Does the 12v system need yo be on at the control panel to have the D+ I've tapped into active? Is it coming from the EBL and as it's not powered on it's not giving out a signal? I've not really had chance to investigate as yet, so not really got down into the nitty gritty. Does anyone have any thoughts on what might be happening here?

I've no idea but I'd measure the d+ voltage with the 50a fuse in and out?

Which EBL version do you have?

Its an EBL119 on a 2021 Bürstner Lyseo

OK - that is not one I know much about. Sorry.

I would put the 50 amp fuse back - certainly, if that is how it came from the factory.

The Schaudt 121545 factory fitted by the (Hymer) factory works with a lithium battery if you set the DIP switch to lithium.
No need to change anything else.
(Some on here may tell you it is not the best profile - but ours has been OK for 2 years and counting)

You don’t need to disconnect the Schaudt booster from the EBL and relay, you can run it alongside the Orion XS. Lenny HB suggested in other threads that putting a switch on the D+ to the Schaudt Booster would be a good idea because it doesn’t know when to stop charging. It can be left switched off but turned on if you need some extra boost.

I have my Orion XS running alongside the Schaudt Booster. The Schaudt uses the original wiring and the only alteration is the new switch on the D+ feed to it. The Orion is wired directly to both engine and leisure batteries with new wiring and fuses. The D+ feed is shared with the original Booster but taken from the un-switched side of the wire.

If the Orion is not working it may well be in the settings. The first thing to check is that the engine detection function has been switched off which allows the D+ switching to operate.

 

[Alanf75]

I'll reinstate the 50amp fuse and see what happens then. I've adjusted the setting for the Orion to turn off the engine shutdown detection or whatever it's called. Hopefully that will get me a bit further.

According to the EBL 119 wiring diagram, the D+ signal comes in to the EBL on pin3 of Block2 (the 5-way connector), and is directly wired to pin2 of Block2 (the 4-way connector). No switches or diodes, just a wire link.

Another thing, if there is a Schaudt booster fitted, the split charge relay will already be taken care of one way or another. So no need to worry about it, I think. Have you removed the wire link between H and L on the Orion XS, and wired the D+ to the H terminal?

 

[Alanf75]

Thanks autorouter, and yes, the link wire is out and I've connected the D+ into the H terminal. I'll add the 50a fuse back in and see what happens but also scope to then add in a stitch to the D+ on the booster if necessary

on mine (2020 Carado), the d+ line to the Shaudt b2b was taken from an automotive relay not from the EBL. The supply to that automotive relay came from one of the circuits on the EBL that is switched on/off by the "master" 12v switch on the main panel . So if you used the main 12v switch as a master to turn off the hab lights for driving, that immediately disabled the b2b! it would never have worked. clearly the dealers story that the previous owners didn't use it much (or perhaps were always on EHU so never noticed) was right. Its possible you may have the same thing. scratched my head for a while but actually easy to check if you know what you are looking for - check voltage on the D+ line you are using, with engine running with main panel on, then panel off.

Thanks ian27 I will keep that in mind and was something I was considering could be a possibility, so good to know it's not just a figment of my imagination. I will check the necessary.

Not sure why you would want to turn the EBL/main switch off while driving. I never do.

Reading this with interest as I'm still using the engine shut down on my 30a B2B. So, the on the 119 Electroblok, it would be the Purple coloured wire I would need to feed to my B2B and remove the jump link, which is just to the rear of the E.Blok. Is a wago connection acceptable?

as a master light switch. save going round turning them all off individually. At some point I'm going to mod the wiring so I have this as a separate switch. don't want to divert too much from the OP's thread ;-)

I use wago's for pretty much everything.

Just a quick update on this as I've managed to rectify the problem.
I plugged the 50a fuse back in and tried with the control panel on and off and still no joy so I went back to where I'd tapped into the D+ and took it apart (Wago's) and reinstated but took a bit more care this time and it now works as expected. I took the opportunity to install a switch for the Booster at this point so now the Orion is the primary charger and I can add the booster if necessary. Thanks for all the advice and suggestions, but seems it was my own ineptitude all along!
