Exploring North Gas Roaster Automation: Part 1

Hello, In the last weeks I made some trial run with the PID to control a fan and a bulb. My problem is that the control by the PID is not a smooth more or less power, but more a on / off switching after 5 to 30 seconds, which I cannot use for the Huky stove as it

Exploring North Gas Roaster Automation: Part 1

Hello, I am not sure if I misunderstand your problem, or if you you are mixing the different voltages. Acc. to my understanding of the EVPD installation & operations manual: Step 2 of the wiring sheet: The 5 VDC / 400 mA is the voltage / current between the board and the valve. Additionally acc. to ...

Izzo Alex Leva PID Usage

Hello JohnW. Not sure if you feel your question was really answered, therefore two points for you: If you want to change the PID setting temperature just press 1) the down-button followed by 2) the up-button. This enters the change mode and then 3) press the up- or down-button as you need. You need ...

Exploring North Gas Roaster Automation: Part 1

@btreichel :Thank you for the link. Ironically I found your post in the Arduino forum 2 days ago without noticing your post here before. It seems that I managed the big hurdles. Although I did not roast yet, I used my test board and controlled it by Artisan PID via

Exploring North Gas Roaster Automation: Part 1

Thank you all ! Next step successful. (The replacing installation of the damaged driver was just starting the setup, while on the www there are several long and complicate procedures) @Björn: yes it is Windows 7 and yes for sure it is an old installation (old notebooks are wonderfull roaster termina...

Exploring North Gas Roaster Automation: Part 1

For all who are hesitating if to try this setup and who are as concerned as I was about the software topic. It was really easy. (but my concerns were also not pure fantasy). I followed the installation manual {link} from John Hannon and downloaded then the applicable code {link} for fast PWM on IO3 ...

Exploring North Gas Roaster Automation: Part 1

After reading many, many posts again today, I understand that I have to modify the sketch and go the full way. (several of them from you slickrock Thank you) And I will connect directly to the Arduino board, as mentioned above here). In case of detailed questions I think I should start a separate to...

Exploring North Gas Roaster Automation: Part 1

Hello blondica73, first, thank you for your clear explanations. Second I have to appologize, as I choose a photo where the EVPD board is not visible and I did not think about it. In fact I was thinking about connecting the TC4C to the EVPD board. I am not so confident about it, as my TC4C is about

Exploring North Gas Roaster Automation: Part 1

Today I had some time to tinker. Using a set of adapters to change the size and right / left of the thread, I installed the Clippard valve to my Huky stove. As there are several aspects I am not really familiar with, I wanted to check the valve installation first, before trying to control it with th...

Exploring North Gas Roaster Automation: Part 1

Thank you again for your helpful explanations. Especially about the simplification of the plumbing. I fully agree with your estimation about hysteresis for different nominal pressure. I believe that at least the principle for eliminating the hysteresis by a little overswing should not be complicated...
