Join 1, other followers. Something else that can cause wide swings with a PID controller is if your cycle time is too slow. I once tried to autotune my Fuji PID controller using a setpoint value that was within a degree or two of 1st crack.

If this doesn’t apply to your situation then I’m not sure what the problem ddtb be but maybe others more gifted in the art of temperature control can help. It keeps the output switch on even though the temperature is way above the set value.

After autotuning, the Fuji would behave similar to what you’re describing, way under and way overshooting. The need for cache clearing get’s me every time!

Thanks for the replies. I’ve found it necessary to autotune farther into a roast where the beans are at least starting to brown. I know the feeling when you don’t have any nasty 48448 to use as tuning fodder but it’s necessary to get it right.

You’ll need beans in there.

You’re 448, glad to help. Default reset by Communication. Blower coil pipe in central air-conditioning system, heating system. Maximum 3 groups of alarm switches are available, with 18 alarm modes each.

Data Privacy Policy OK. I changed it to 1. I put it back at 1, as that seemed more than adequate. Merry Christmas to all.

Or you use the LED code of the manual to guess the protocol and address Or just follow the below instructions to take the DTC back to factory defaults: The ones of you who deal with Delta temperature controllerssooner or later found on the situation to reset the Temperature controller to default values.

Optional CT wire breaking detection function, rtb alarm output. The cycle time control period1 on the Delta software was at Username Password Not a member yet? Optional Event function, using PLC or switches to switch between 2 different set temperatures.

I am attempting to control my Poppery 1 with a PID. But, just in case you end up liking what you have now versus what a new session creates, I would write down your current PID settings so you can revert back to them if needed. Happy new year for you all. Tuning without beans will not allow autotune to see the true thermodynamic properties of the what’s being heated. It was not possible for it to derive usable PID settings when autotuning dt 1st crack due to the vapor release, wacky temperature swings at that stage of a roast.

First Build – 5kg Contact us, and let our staff help you. Am I using the wrong SSR? Yes, as soon as autotune ends, the temperature swings happen, and never stop.

The PID will autotune, and ftb to control the temperature quite well during that 20 to 60 second period, then drb just goes crazy, dropping the temperature 75 degrees, then overshooting the set value by 50 degrees.

Autotune may not have been able to derive the best PID settings using the 20 second cycle time. Celsius or Fahrenheit temperature display.
