Brooke Posted June 22 Share Posted June 22 Good afternoon I have an adria lt 500 control panel Everything seems to be working except the light telling me I'm hooked up to mains Everything that is 240v is working in the van but it does not seem to be charging the leisure batteries The question mark is flashing indicating a problem Any help would be greatly appreciated Quote Link to comment Share on other sites More sharing options...
Keithl Posted June 22 Share Posted June 22 Does everything work on 12 Volts when the EHU is unplugged? 1 Quote Link to comment Share on other sites More sharing options...

As you say it only shows a ? mark when on hook up. 1 Quote Link to comment Share on other sites More sharing options...
Robinhood Posted June 22 Share Posted June 22 I'm in Canada, so don't have access to the manual, but I think the why signal comes from the ebl. If your leisure battery isn't charging, I'd check the charger fuse on the ebl, or any rcb if the charger is on it's own circuit. 1 Quote Link to comment Share on other sites More sharing options...
Derek Uzzell Posted June 23 Share Posted June 23 A copy of the instruction manual for the Schaudt LT 500 control panel can be found here https://www.manualslib.com/manual/1405678/Schaudt-Lt-500.html#manual 1 Quote Link to comment Share on other sites More sharing options...
Robinhood Posted June 23 Share Posted June 23 I've just looked at a sample ebl diagram, and the ehu signal is driven by the charger unit in it. I'm not sure that the charger fuse would prevent the signal, but I'd certainly check it. Otherwise, as I said, check that power is getting to the ebl (dedicated rcb somewhere tripped, or "kettle plug" power input backed off?). 1 Quote Link to comment Share on other sites More sharing options...

The cause of the problem turned out to be the 240 volt plug had fell out from the input socket on the bottom of the EBL 226 transformer / rectifier unit under the seat next to the leisure battery. Simple Fix. 1 Quote Link to comment Share on other sites More sharing options...
rayc Posted June 23 Share Posted June 23 The mains indicator is actually a charger ON lamp i.e. the charger output operates the mains on icon. If you have EHU but the charger is switched off or has no output the icon will remain off. this is how all the Electroblock units I have seen work including my EBL 271/LT72 combination. 2 Quote Link to comment Share on other sites More sharing options...
Brooke Posted June 23 Author Share Posted June 23 Thank you all But to clarify When I'm hooked up to ehu the light does not come on saying hooked up *but everything 240v works When you push the button to check batteries the red charge light comes on and the ? Light flashes red This has only started happening since I had a habitation check on Thursday Quote Link to comment Share on other sites More sharing options...
Keithl Posted June 23 Share Posted June 23 I would guess they have either turned something off or maybe unplugged the charger as suggested above. Time to start checking and testing, or possibly wait until tomorrow and ask whoever performed the hab check! 1 Quote Link to comment Share on other sites More sharing options...
Robinhood Posted June 23 Share Posted June 23 2 hours ago, Brooke said: But to clarify When I'm hooked up to ehu the light does not come on saying hooked up *but everything 240v works The EBL plays no part in the functioning of the 240v circuits, other than requiring a mains input to the battery charger. The presence of this input is what illuminates the mains light on the panel. If the EBL charger isn't functioning, the other 230v units will work, but the mains light won't illuminate, and the batteries will not charge from ehu. If the charger itself isn't worked, then it probably isn't getting mains input (though the other units are). You should check the MCBs at the mains input point, check that the mains input to the EBL is connected and secure (it's usually a kettle type plug) and check that the charger fuse in the EBL front hasn't blown. It occurs to me that removing/blowing the main leisure battery fuse (which could be anywhere) might also inhibit the charger, but this can be checked by testing the 12v system (e.g. a light). 1 Quote Link to comment Share on other sites More sharing options...
rayc Posted June 24 Share Posted June 24 From the LT 500 manual section 5.3 : "The yellow 230 V indicator lamp lights if the input of the Electrobloc is live. The yellow 230 V indicator lamp flashes if the vehicle's engine is started and if at the same time the input of the Electrobloc is live." In my opinion the first sentence should have "and the charger module has an output" added. What model of Electroblock do you have e.g EBL XXX? https://www.manualslib.com/manual/1405678/Schaudt-Lt-500.html?page=5#manual 1 Quote Link to comment Share on other sites More sharing options...
onecal Posted June 24 Share Posted June 24 Hi Bring it back to the person, or give them a ring. who provided the habitation check for you. Explain to them you had not this issue prior to the check, Hopefully they may have just turned something off or disconnected something.it happens Regards Quote Link to comment Share on other sites More sharing options...
Brooke Posted June 25 Author Share Posted June 25 Thank you all for your replies The person who did the habitation check tells me he has probably upset the relays and it needs resetting (can't speak direct it's through his wife) he says he can do it in a weeks time Unless somebody knows how I can reset it on here Quote Link to comment Share on other sites More sharing options...
Keithl Posted June 25 Share Posted June 25 If you find your MH's power supply unit you should find Circuit Breakers and an RCD similar to your house 'fuse box'. One will be marked something like 'RCD' and have a 'Test' button. Try turning this RCD switch off and back on to reset it. Quote Link to comment Share on other sites More sharing options...

If so is there power at the plug? Edited June 25 by rayc Quote Link to comment Share on other sites More sharing options...
Robinhood Posted June 25 Share Posted June 25 There is a similar contemporaneous thread running here, describing the same symptoms with the kettle plug having detached on an Adria. https://www.motorhomefun.co.uk/forum/threads/ehu-light-not-showing-up-on-panel-but-240v-sockets-work-solution.304409/ I must admit, with the control panel you mentioned, I'd expect an EBL, not a Nordeletronica unit, but they may mix and match. Whatever, it's still a reinforcement of the advice to check the mains connector at the charger. Quote Link to comment Share on other sites More sharing options...
Derek Uzzell Posted June 25 Share Posted June 25 On-line motorhome-related discussions indicate that Adria was installing Nordelettronica electrical equipment in the mid-2010s, often pairing a NE237 unit with a NE266 or NE166 control-panel. As Brooke's Adria has a Schaudt LT 500 control-panel the rest of its electrical 'kit' will almost certainly be Schaudt-made too and include an EBL. (It might be useful to know which Adria model Brooke owns and when it was built.) Quote Link to comment Share on other sites More sharing options...
Seth77 Posted June 26 Share Posted June 26 Check if the mains connector to your charger unit is loose sometimes it's just a plug that’s wiggled free. Quote Link to comment Share on other sites More sharing options...

The van has been in the garage for 4 weeks they changed the charger unit but the lights on panel stayed on indicating a problem apparently everything is working but the panel is not recognising the batteries I have the panel which I'm taking to a specialist tomorrow When I put my theory forward they seemed to agree I really am at my whit's end with it all Quote Link to comment Share on other sites More sharing options...
