I have a 20x24 flash unit. It is basically a big oven burner. It uses an Omron E5C4-R Temperature Controller and it was wired into a JGX-1 A4840 SSR which controlled a simple LED light and a large oven like coil to produce heat for flash drying ink on a screen printed t-shirt. I was forced to delve into this because the SSR caught fire and melted. Not a fun thing. So I looked around but could not find the same SSR available in the US so I found one that APPEARS to be the same: MGR-1 A4840. I googled as mcuh as I could looking for comparisons to see if it would be a compatible replacement for the original SSR. The specs all read the same as far as I could tell so I went with it. I did take some pictures of the original connections but it was so convuluted that I can no longer be sure I am anywhere close to wiring this correctly. My problem is this: When I try to wire it up the way it appears in my pictures and how the data sheets read to me I can't get this to work, this being the Temperature Controller to trigger the SSR to turn on/off according to temperature. 1) I purchased the MGR-1 A4840 SSR to replace the original JGX-1 A4840 SSR 2) I purchased a replacement E5C4-R K 0-399 to replace the original of the same model 3) I purchased a replacement thermocouple Assuming the melted SSR may have damaged the Temp Controller I wanted to replace both. I can get the Temp Controller to power up and read the thermocouple just fine. The issue comes in wiring the control from the Temp Controller to the SSR. I have been looking at this issue for so long my eyes are crossed and my brain is fried. Attached are pictures. There is a 4 prong rocker switch, an LED lamp/light, the SSR, the Temp Controller, and the heating element. If someone could help me in figuring out how to re-wire this I would be most appreciative. I assumed that the Output voltage would trigger the SSR but I do not get any voltage at all from what I read as the Output on the Temp Controller. THANKS in advance for any help you can provide.
