This feature is available starting from Firmware v1. You’re welcome, glad to help. In this case, you have 2 options: Tuning without beans will not allow autotune to see the true thermodynamic properties of the what’s being heated.

Maureen, FYI, during an autotune session, the firmware will take the setpoint value way over the setting you made for X time and way below your setting for X time to determine the hysteresis of the device being heated and make the necessary PID calculations. I changed it to 1. Programmable logic controller is able to set up 64 sets of temperature and control time.

Blower coil pipe in central air-conditioning system, heating system. Communication is RSso follow the twisted pairs recommendations when possible. First Build – 5kg Or you use the Ftb code of the manual to guess the protocol and address.

When I re-did the autotuning using for a setpoint value it worked as it should. After 5 seconds, the device should show as below picture.

I’ve been communicating with the Delta guy, I am successfully connected to my laptop, and have the software set up. Merry Christmas to everyone! I am trying to tune at f, but with no dfb in the popper, so perhaps it is too volatile to tune. Default reset by Communication. 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.

If this doesn’t apply to your situation then I’m not sure what the problem could be but maybe others more gifted in the art of temperature control can help.

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. Automazione per gli Edifici. Repeat the steps 3 and 4 three times within 60 seconds488 If everything is OK, all led should switch to ON as below picture.

There’s nothing that will keep one up late and unable to sleep more than when our roaster is not feeling well! 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: This is usually the last phase of an autotuning session.

Have a question or need any assistance that should be answered by a professional? Optional Dt function, using PLC or switches to switch between 2 different set temperatures. Yes, as soon as autotune ends, the temperature swings happen, and never stop. By using this website you agree to the placement of cookies. I’m ramping, I’m soaking, I’m roasting!!

Delta, Delta 100 to 240 VAC & 24 VDC Delta Temperature Controller DTB

The PID will autotune, and seems to control the temperature quite well during that 20 to 60 second period, then it just goes crazy, dropping the temperature 75 degrees, then overshooting the set value by 50 degrees. Something else that can cause wide swings with a PID controller is if your cycle time is too slow.
