So, if you display your PID settings before and after autotuning, there’s no change in the values? Am I using the wrong SSR? If this is the case then there might be a way to improve things.

This device have no buttons. Optional Event function, using PLC or switches to switch between 2 different set temperatures. In this case, you have 2 options: Communication is RSso follow the twisted pairs recommendations when possible.
It now works great. Some odd Artisan or TC4 problems. Contact us, and let our staff help you.

Or you use the LED code of the manual to guess the protocol and address. I changed it to 1.
DTB Temperature Controllers
This feature is available starting from Firmware v1. But what happen with DTC? It keeps the output switch on even though the temperature is way above the set value.
When I re-did the autotuning using for a setpoint value it worked as it should. Join 1, other followers. Hi Brandon, please disregard the “please update”.
I’ll try again tomorrow and sacrifice some more beans to the cause. Email Subscription Enter your email address to subscribe to this blog and receive notifications of new posts by email.

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 48848 for X time to determine the hysteresis of the device being heated and make the necessary PID calculations.
By using this website you agree to the placement of cookies. I am trying to tune at f, but with no beans in the popper, so perhaps it is too volatile to tune. Blower coil pipe in central air-conditioning system, heating system.
Autotune may not have been able to derive the best PID settings using the 20 second cycle time. Thanks for the replies. I’ve been communicating with the Delta guy, I am successfully connected to my laptop, and have the software set up.
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: Something else that can cause wide swings with a PID controller is if your cycle time is too slow.
I’ve found it necessary to autotune farther into ddtb roast where ddtb beans are at least starting to brown. Have a question or need any assistance that should be answered by a professional? I put it back at 1, as that seemed more than adequate. Fans and Thermal Management.
Repeat the steps 3 and 4 three times within 60 secondsand If everything is OK, all led should switch to ON as below dyb. The cycle time control period1 on the Delta software was 484 I’ve followed his instructions, but the results remain the same.
