sixwheeledbeast Posted May 15, 2018 Share Posted May 15, 2018 IMO there is not enough tolerance with 1k/1k. Seems to be common issue on Galaxy to have intermittent hi/low res faults compared to other resistor configurations. Not to say reed switches don't go faulty.

Galaxy Classic 504 lol. Those panels are reliable apart from the PCB mounted battery corroding. Just replace the contact and you'll be up and running again. That said, a 2nd hand dimension is very cheap these days. Quote Link to comment Share on other sites More sharing options...

This was on a galaxy 96 not that it makes any difference. Contract must be worth it though Quote Link to comment Share on other sites More sharing options...
jackaddressable Posted May 16, 2018 Author Share Posted May 16, 2018 8 hours ago, whistle said: The cqr ones we have problems with have links you cut for the desired resistance. we now use knight plastic contacts YEND 74 for 99% of our jobs. Yeah, cuttable links inside. It is a shame because I like the design of them, but they do need to work. 7 hours ago, GalaxyGuy said: Those panels are reliable apart from the PCB mounted battery corroding.

Also, I have seen a few Dimension panels on eBay, I've always got an eye out for when this goes. Quote Link to comment Share on other sites More sharing options...

Yes plenty of hot dimensions going cheap in eBay Quote Link to comment Share on other sites More sharing options...
GalaxyGuy Posted May 16, 2018 Share Posted May 16, 2018 The battery is soldered on the old panel. It's not required until power and battery backup are both lost, where it then backs up the panels static memory until power is restored. Not really worth fixing, as replacing with something newer is probably a better path to take. Quote Link to comment Share on other sites More sharing options...
KWCFC Posted May 16, 2018 Share Posted May 16, 2018 (edited) I don't understand why galaxy have the "high resistance" fault function? We use castle and it either works or it doesn't... I dont see the advantage. Edited May 16, 2018 by KWCFC Quote Link to comment Share on other sites More sharing options...
