So I lost my last brewery is a ****ty (no pun intended) sewer back-up a few weeks ago. While this sucks, i'm pumped to be able to build a better system with a higher level of control.
I've been toying with a few ideas and i think that my new system is going to be a BCS-460 controlled 2 vessel all electric system modeled similar to the counter top brutus with a few changes.
It will be a 2 vessel system, 1) HLT/Kettle and 2) MLT, run on 240V 30 breaker. I plan on having both manual and auto control settings, so if the bcs ever stops working i'm still able to brew. I'll be converting my old stand to accomodate the 2 vessels and new control panel.
P-J, could i get you to help me out with a wiring diagram for my new control panel?
This is what i have so far:
1) all controls will be housed in a 20x16x8 nema 4 control panel
2) i have a 12" windows based touchscreen panel pc i'm going to connect directly to the BCS-460 (its takes 120V input power)
3) i would like to have the option to control the element(s) manually and with the BCS
4) i want it to have an e-stop which would kill power to everything except the bcs and touchscreen panel pc
5) i'd like to be able to start the whole system up with a key switch
6) for now there wont be any electronic ball valves, but i might add them later
7) i also want to stay flexible so if i decide to upgrade the system back to a 3 vessel i will be able to do so
So far i have collected the following to begin work:
- 20x16x8 electrical enclosure
- 12" touchscreen panel pc
- 30a dpdt 120v coil contactors (2)
- 3 pos, maintained, NO switch (2), with 2 additional NO contact blocks for each (1 for the element in the HLT/Kettle combo, the second if i want to upgrade to a 3 vessel system)
- 2 position, maintained, NO switch (for chugger pump)
- mushroom e-stop
- 2 position, maintained, NO key switch
- green 120v LED pilot lights (3), one for each element and one for the pump
- blue 120v LED pilot light, for then keyswitch main power
- red buzzer/LED pilot light, for BCS timer alarms
- pushbutton, non-maintained, NO to reset BCS buzzer/timer alarms
I still have to get the BCS, SSR's and all the plugs for the elements, main power, temp probes and pump.
