Anyone here an HVAC tech? I'm wondering if my circuit is ok and I don't go back to class until Tuesday. This was from my third day so consider that when you see how crude this is.
>first pic is wiring diagram
>second pic will be my drawing of how I did it in class
>third will be my simplification of it.
schematic looks sorta awright. i'm not looking at the last 2 drawings coz it's too much work.
- the transformer is drawn wrong. there's no secondary coil.
- having a legend is stupid; you have to keep shifting your gaze between the wiring and the legend.
- the compressor uses two different contacts, which doesnt make much sense, unless you wanna isolate it for safety - in case some idiot wants to work on it while powered.
I just realized you think there are two seperate contactors, L2 is fed from the contactor as well as L1. You sure you read that right?
My original question was if my third pic was good with the pigtails and all. If you're too lazy to examine I understand.
the wiring in the last drawing is all ok, but the drawing itself is far from perfect. if you position the parts logically, in a manner similar to the schematic, then you end up just 4 or 5 crossed wires, instead of it looking like spaghetti, with about 25 cross-overs.
here's where the magic happens, two to a station. tiny spaces, we're trying here in America.
I'd have put the live jellyfish at the top and the ground jellyfish at the bottom.
The majority of your crossing tentacles are relatively-boring live and ground ones, and you can emphasise their boring, rail-like nature by putting them at the top and bottom like in the circuit diagram.
also why have you got an transformer inducting onto nothing ? and do you have to show what type of D.c motors you'll be using for the fans? i'd suggest a shunt motor as you want the speed to be constant and the way you have to wiring set up indicates that
ladder diagram matches with circuit drawing fine. just add the secondary winding on the transformer.
aside from that, i would wire the OFM so both sides are off CC. i hate when they leave one line live to condenser fan motors, especially when there is a perfectly good two pole contactor right there.
also, why have a pilot light on when unit is off?
