The voltage is too high. I would check all the solid state relays.

As I said, I'm new, and I've never seen the adhesive dot method. I'm certian our company will stick with paste, though, because we make our own boards (with a vertical plater no less!!!) and contamination is quite an issue. We do a fair amount of rew

We swapped the solid state relay for zone 5 bottom to zone 5 top but the problem came up once a while. As for noise protection, there are jumpers at E1 to E8 and E9 to E16. They are hardware filters and prevent noise spikes from affecting thermocoupl

Have seen this problem on other types of oven and it was caused by failed solid state relays that energise the heaters.

Try to check the SSR (Solid State Relay) in the back panel. You may need to replace one or some of them. Good luck.

On a our electricity ovens the most common problem with overheating zones is usually the solid state relays.Not sure if this would relate to the Heller ovens.

Last time we looked at this, JEDEC carefully designated the dimensions of the carriers, but "neglected" to define the component orientation with the carrier. Go to http://www.jedec.org/download/, search for JEP95 JEDEC REGISTERED AND STANDARD OUTL

I've had the relay that controls closing the lid go bad It's a solid state relay if I remember correctly. Are you talking about a motor driven lid? edit now I"m trying to remember if that place had conceptronic ovens and that's what I"m thinking of

DucHoang, thank you for your reply. as you mentioned I checked the solid state relays on the input and output side. I did get power coming out of all even when the conveyor was stopped. I will mark them with their position and swap some to see what h
