Thank you for your response. I did this: I changed the whole machine FCM and the FCM II, as you write me everything changed. Programmed new EPROM, etc. FCM machine and it works perfectly as FCM II. Only now I've changed the option to push mechanicall

Do you have the electrical schematic? The matting connector should be right there at the machine frame just under the mounting hole for the light tower. Light Towers can be an "option" on machine configurations, perhaps your machine was not configure

I was at our local SMTA Michigan Chapter Tech Forum & Tabletop Expo last week and BTU was introducing a new option designed to reduce flux build-up in the heating zones. Might not be a bad idea to reach out to them to learn more about it. Just a sug

Who can blame anyone for having lousy service in China when there's twenty companies selling cheap throw away ovens for $20K new. What's surprising is why would BTU, Ersa, Vitronics and Heller even try to sell over there anymore.

Link Fail is the RS232 connection to the FCU. I would check the connector, cable that plugs into the computer. Verify all power supplies are working. The most likely scenario is this: Computer malfunction Cable / connector issue. Defecive FCU

Please check the following: 1.Power supply. 2.SSR control power. 3.OTP or over temp protection at the software. Maybe you set it at low so it reads over temp even at lower temp. If still not ok you may check BTU service engineers. Brian Riggs

In 1995 we bought 4 Vitronics U520 reflow ovens with top heat only. We ran these ovens until 2003 for both curing and lead reflow with no problems. In 1998 we bought 1 U520 top and bottom heat and one U820 top and bottom heat and once again we had

I would really suggest staying away from novastar on their ovens- we had a really bad experience with two of their ovens being unable to maintain temperature properly. We ended up buying a used BTU VIP70 and it has been working out great. A Heller 18

Hi Mark, Check out Heller's white paper link for a study done with a PCB in line with thick and thin aluminum plates to measure repeatability and delta T with loads of large mass materials. The result was less than 1 degree with their oven due to i
