I have assembled my scalar xl with smoke detector, but the smoke detector doesn't work. If I turn it on the detector wil get a little hot, that is oke. And when I turn on the printer I get direct a alarm that smoke is detected. When I try to adjust the detector with the blue trim nothing happens even the red LED doesn't light up. When I disconnect the blue wire then the red LED turn on when I adjust the blue trim but the alarm on the display stay on.
What to do?
The wire diagram on your site is not correct, the 5v connection on supply printplate on the photo is incorrect.
Problem is solved. The connection of the blue wire on the power supply was not correct. The photo wire diagram on the site is not correct, the "+" and "-" printed on the power supply case is correct. See picture
