I'm ready to start the build. I got a great used SS box from a renovation job I just did. It's 17"× 22" X 7 1/2" . The only thing is, it's not hinged. Not a big deal to me. I could hinge it, but I don't really think it's a necessity to me. It has a large hole in the top right corner. But I solved that problem by using the E stop to cover it up. It seemed like a natural place for it anyway.
This box seemed huge to me at 1st, but when I was laying out my design, I was running out of real estate fast. I guess you could squeeze this design in a smaller box, but all the research I've done on here indicates that "A bigger box is better". I can see why. So, can you guys have a look and let me know what you think?
Any feedback is welcome. I think I covered all bases, but maybe not. I probably missed the obvious. Lol. The only things I think I may need, is an "element power on" switch, and a "pid selector switch" I don't think in my set up, that's required.
I thought in lieu of the above, the interlock would do the same thing? I could be wrong. I think the wiring for this should be pretty straight forward because, this is how I envision the use of It.
When the keyed switch is turned on, all the pids will be powered on and be working as they should, BUT, NO power will be available to either of the 2 heater elements, or the 2 PUMPS, untill I turn either the HLT, BK, or Both "ELEMENT ON/OFF" switches to the ON position. If any of those switches are in the ON position, The panel should NOT power on. Pretty simple I think.
I thought that the safety interlock circuit will prevent the powering up of the panel if any of the 2 heating element switches ***OR PUMPS*** are left in the ON position.
And each pid has an alarm switch on/off , and a indicating light. That's pretty much it.
All red caps are lights
All black caps are switches
The rest should be obvious.
Let me know what you think please
