I've looked at an INSANE number of electrical diagrams over the past 8 - 10 weeks and my brewery build is just taking WAY too long and I need something simple that I can use to just get brewing ASAP and I'll buy a 2nd box and start building a more significant control panel separately when I have the luxury of taking my time.
What I'm looking for:
A VERY, VERY simple wiring schematic for a single SSR, single PID 30 amp 240v system.
I want to be able to switch the SSR output between both the HLT and the Kettle. I'd like a 3 way switch for controlling the power output to the elements:
-"Off" -which should turn off the power to both legs after the SSR to ensure that power is TRULY off, "HLT", and "Kettle". (I don't understand which contactor and which control switch to buy.)
I'm wary of having a single PID control both the HLT and the kettle because switching the PID controller between two temp probes (even if they're the exact same type and cable length) can screw up the PID calibration because of the different vessels (the geometry and size are different) so I'd also like the ability to switch which PID controls the SSR. (With 2 controllers I don't need to mess with switching from holding a static temp in the HLT to %output mode for the boil kettle. -I'm thinking just a simple 120v illuminated push-button on/off switch would work for this and I happen to have 2 already. My guess is that I can just simply turn off one pid and then turn on the other and wire them both to the control leg of the SSR.
I don't want to deal with circuit breakers in the control panel box; a simple in-line fuse for the PID controllers is good enough for me.
I'd actually appreciate an "E-stop" button and wouldn't mind a flashing alarm output for the PIDs in the event that I try to dry fire an element or something...
-Will the illuminated 3 way switch LEDs actually provide a reliable indicator of whether the elements are actually on or off in 100% of cases in this wiring diagram?
