Anyone have any idea why a PID would turn off power to a melting pot. I raised the temp to clear a frozen pour spout. Looked back about two minutes later and the temp os decreasing at about 5 degrees a minute. Power is still on and the display is functioning.
Any help would be appreciated.
Could be a couple of different things.
Verify output voltage is 110vac-120vac (plug a lamp into the outlet)
Yes ? - bad heating element in pot
No - next step
Get a volt meter.
Measure that the SSR has 3-32 vdc on the control input.
No - improper setting on PID or if was working then failed PID
Yes - next step
Verify voltage at SSR Term # 1 (line side) is 110vac-120vac
No - check fuse if you have one or possible broken wire
Yes - next step
Verify voltage at SSR term # 2 (load side) is 110vac - 120vac
No - faulty SSR - replace and retest
Yes - next step
Plug lamp into outlet and verify it works
Yes - bad heating element on pot or faulty pot side wiring
No - faulty output plug/wiring
That's a quick check list.
Thanks Hatch. Will look into it. Shut it down for lunch, went back out in the shop and everything is working. .?????
Operator error?:confused:Quote:

I would be very leary of walking away from that plugged up
I disassembled the whole thing to clear the spout freeze. A mystery metal had locked the pour spout solid. Had to use a torch to melt it out. Cleaned everything while I had it apart. Reassembled it all and it works fine. Could have been a loose wire, but the gremlin is gone for now. I never leave equipment alone while in use. Learned that lesson long ago.

Does your PID have a variable defining a maximum temp, beyond which it shuts off the electricity to the pot? Just curious if that could be the issue...
Don’t know. It is the stock PID from Magma that came with the Master Caster. Could be.
I've got a jld612 (1 of 3 PID's I use) that does a temp nose dive after it comes off auto tune. I wasn't happy with the overshoot and under after auto tune. Tried setting PID parameters by hand and said heck with it. Use it as a simple thermostat. Less cycling and wear and tear on SSR. Only two cycles on and off while Hi-Tek baking. Temp goes from 388-400. Best bond yet bullet to coating.
Can you reset to factory settings, do an auto-tune and see if it works properly? I've had an Auber PID act weird and when I checked every single setting I found that some were set improperly. I just reset to factory, did auto-tune and all was great.Quote:
