Hello,
I am having some issues with my setup. I'm not sure if the issue is in my wiring, or if I might have a defective PID or defective SSR. I have attached my wiring diagram and below are some more details:
I am using the MYPIN TA4 PID Controller.
I will set my target temperature. As the actual temperature approaches the target temperature, the output light on the PID and the light on the SSR itself will begin to blink. Once the temperature exceeds the target temperature, the output light and the SSR light turn off completely. However, the heating element stays on.
Eventually, I unplug the entire unit from the wall and the heating element immediately goes off obviously.
I will plug the unit back into the wall (at which point the temperature is still above the target temperature) and the heating element does not come back on. It only comes back on once it has dropped again below the target temperature. It then climbs again and overshoots the target to repeat the process.
To troubleshoot, I disconnected the wires connecting the PID to the SSR and tested to see if the elements turned on, and they didn't, so I don't think the SSR is stuck.
I also figured this might be an autotuning issue with my PID controller: Everytime I go to autotune, the autotune light comes on (solid) and then stays on. I have let it go for up to forty minutes at times and it never goes off (which to me seems like its not completing the autotune process). Further, when I go into the settings on the PID, the P, I, and D values are all at their default, so the autotuning never changed them. So as of now, I'm leaning towards a defective PID? Unless you all have some other ideas.
Attached is my wiring diagram. It is using a 220v plug.
Thanks in advance to anyone who can help.
