Guest advent750 Posted November 8, 2004 Share Posted November 8, 2004 Hi again. I`ve changed the transformer to a 12v 50va ( the only one they had in stock) and I`ve also replaced the battery with a 7Ah one. The system still shows a message on the screen as TRBL Supply, but it can be set and used as normal. Any ideas on this one. Link to comment Share on other sites More sharing options...
Brian c Posted November 8, 2004 Share Posted November 8, 2004 I'm pretty sure that if your confident that, around 16-24Vac is getting to the Abacus PCB terminals, and you can't clear this message, then whichever component(s) control the power monitoring have packed in. I'm afraid it's a new panel!! If you don't know......ask. Link to comment Share on other sites More sharing options...
Guest advent750 Posted November 8, 2004 Share Posted November 8, 2004 Does it have to be 16-24v at the terminals. Will a 12v supply with a high va rating not do the same job. Link to comment Share on other sites More sharing options...
Service Engineer Posted November 8, 2004 Share Posted November 8, 2004 The 12 VAC TX once it`s gone through the rectifying circuitry and smoothing caps should produce around 18VDC at the regulator, so as far as I `m aware shouldn`t have caused any problems, especially with the TX being 50VA too. ........................................................

Service Engineer Posted November 8, 2004 Share Posted November 8, 2004 What voltage DC are you getting at the AUX terminals..? ........................................................ Dave Partridge (Romec Service Engineer) Link to comment Share on other sites More sharing options...
Brian c Posted November 8, 2004 Share Posted November 8, 2004 Does it still work without the battery connected? If so I reckon the monitoring circuitry must be looking for 18Vac (rated in manual) as the system operates but the message is still displayed. If you don't know......ask.

Guest advent750 Posted November 8, 2004 Share Posted November 8, 2004 I`m getting 12.8vdc at the bettery terminals and 12.6vac at the ac terminals Link to comment Share on other sites More sharing options...
Service Engineer Posted November 8, 2004 Share Posted November 8, 2004 Are there any other tapping points on the transformer..? Whats the VDC with the battery disconnected..? ........................................................

Brian c Posted November 8, 2004 Share Posted November 8, 2004 and 12.6vac at the ac terminals 30785[/snapback] There's your problem, I reckon. If you don't know......ask. Link to comment Share on other sites More sharing options...
Service Engineer Posted November 8, 2004 Share Posted November 8, 2004 I think you may be right Bri, the panel circuity is looking for a higher voltage and reporting a fault becuse its lower than expected. The panel will probably work ok, except for showing the fault. ........................................................
