Comments on: Copycat PID-Controlled Solder Hotplate http://www.neufeld.newton.ks.us/electronics/?p=537 Sun, 08 Dec 2024 17:19:24 -0600 hourly 1 http://wordpress.org/?v=3.1.3 By: Swany http://www.neufeld.newton.ks.us/electronics/?p=537&cpage=1#comment-34901 Swany Tue, 01 Mar 2022 18:23:30 +0000 http://www.neufeld.newton.ks.us/electronics/?p=537#comment-34901 I did find workaround (for the moment). The SL6 parameter was set to "0011" from the factory. According to the limited docs supplied with the PID, the first bit controls "direction". If I change this bit by using "0010". The PID OUT1 and OUT2 are reversed (as expected). So now when heating is required the OUT2 LED illuminates and when cooling is required the OUT1 LED illuminates. This doesn't help me since I still get 12VDC on the OUT1 terminals when either OUT1 or OUT2 are on. So I but that bit back to 1 and tried flipping the undocumented bit 2. I tried SL6 = "0001" and now OUT1 comes on when heat is needed and OUT2 never comes on. So for the moment this gets me going since I have not yet added active cooling. I still would like an answer if anyone knows how one is supposed to differentiate the heating and cooling states. I did find workaround (for the moment).

I bought two and they both exhibit a behavior that prevents me from getting my system going. When the current temp is under the set point, I see 12VDC on the OUT1 terminals (5/6) as expected (PID is calling for heat). However when cooling is needed, I also see 12VDC on the same OUT1 terminals. This means my SSR is on when heat is required and when cooling is required. When neither OUT1 or OUT2 LEDs are on the terminals show 0V (as expected). Is it possible there is a parameter I need to change so OUT1 terminals only have voltage when OUT1 is on?

Simply awesome projects! Unfortunately, I am not a pro sparky like you and Fred. If either of you could do a wiring schematic for your hot plate projects, that would be awesome! My nickname is this realm would be 'smoked-it'. Or Great-Balls-of-fire! I am at this level of sparky knowledge: https://youtu.be/1P6hqQWd3Vw My motivation for doing this project comes from buying a welders ruler from the famous youtube 'Ave' above. It comes with a 1206 LED smd electronic component 1206 LED to solder on in the form of a mini kit that comes with his ruler. You need a microscope to see this little part. I want to do other electronic projects and experiments also with the hot plate. I am nearly done converting an old computer power supply into a bench supply so my soldering skill is improving some and no blue smoke yet ;) For instance, one of you used a panel mount 110v female socket with a line filter attached. I am not sure how that is wired to the Sure Pid or SSR. I am not sure how your going to wire a 12V fan to your Pid. A wiring diagram would really help a novice like me out. Since Fred is now using the same Sure CD101PID since his Omega PID died. I am going to eagerly follow the two of your improvements/updates to your hot plate projects. Thanks guys! Bill Mac Hi Keith,

Currently I needed to set up similar hotplate/chuck and I found your post. It would much helpful if you share the wire connection bettween PID, SSR and Cartridge heating unit. thanking you in advance! Hi Keith,

So you'd (probably) connect out1 to the input of your solid-state relay.

Im working on a similar setup with heat plate, 2 heating elements (unsure whether to wire in series or parallel) and a type k thermocouple. My controller also has out1 and out2 but not sure which one works best for what im looking for. Help would be appreciated Hi there Keith,

I like being able to move things around and poke solder bridges while it heats, but that's definitely worth considering. Lee, that’s a really interesting idea; thanks!
