Damian Posted July 23, 2020 Report Share Posted July 23, 2020 A bit of a weird situation with the unit in title. It is installed and working as you would expect (new application, just programmed this week), but I noticed some odd noises coming from it. I disconnected all the connectors and cables except for the 24VDC supply and it still makes the noise. When I cycle power to it, it is quiet up until it completely finished booting and then runs the application. As soon as the application starts running, the unit starts making the crackle sound again. There are not any relay IO, so it can't be a chattering contact. It is hard to tell if it is the speaker or something else. Attached are a couple videos where hopefully you can hear the audio OK. Any ideas on what it might be? UniStream Snap Crackle Pop.mp4 UniStream Crackle.mp4 Quote Link to comment Share on other sites More sharing options...
