WIRING HELP!! on my newly aquired King model KC401-V2F 3 phase 575

[mlalonde]

I wanted to add a couple more pics. The power comes into a junction box Ill call it. Then into the control panel. Then the 6 black and 1 green come from the control panel to the motor. Hope this makes sense Doc

Mlalonde, can you give me the drum switch manufacture's name, model number, and visible terminal numbers? It may be a little different from the JPM.

Ok so here is a couple pics of my Drum switch. I also checked every wire and number on the switch. It is as follows

The 6 black wires are numbered 1 through 6

No. 1 wire goes to terminal 4 on drum switch
No 2 wire goes to 7
No 3 Wire goes to 12
N0 4 wire goes to 1
No 5 wire goes to 6
No 6 wire goes to terminal13

Theres 3 other black wires that go to the drum..They come from inside the control box.

T1 to terminal 14 on the drum switch
T2 to terminal 2
T3 to terminal 5

i thought there were reversing contactors involved with your drill, the pictures prove it!


I don't really want to be the bearer of bad news...

rewiring may be a bit sketchy at best, there will be lots of tracing and identification.

without a wiring diagram from the manufacturer, you have 3 choices (of the top of my head)

A: design your own control system

B: copy a 2 speed reversing contact control system from another manufacturer

C: convert to VFD and run the drill in Wye configuration


option C will be the most expedient method

Thanks Doc

And all because he disconnected the 6 wires?

King Canada Gave me this diagram . They said its for this machine. Might make sense to you! Thanks again!!

Hi @mlalonde ,
I was concerned that something is wrong with the drill, as well as otherwise other unknown factors.
if the old owner decided to rearrange control or contactor wiring.
any modification to they systems could present dangers to you.

if were to counsel without certainty that the circuits are identified and wiring in the correct places,
i would be doing you a dis-service.

i would not want to put you in danger, my friend

 

[Ulma Doctor]

since you have given a diagram i can better help you

Ok so here is a couple pics of my Drum switch. I also checked every wire and number on the switch. It is as follows

The 6 black wires are numbered 1 through 6

No. 1 wire goes to terminal 4 on drum switch
No 2 wire goes to 7
No 3 Wire goes to 12

No 5 wire goes to 6
No 6 wire goes to terminal13

There's 3 other black wires that go to the drum..They come from inside the control box.

T1 to terminal 14 on the drum switch
T2 to terminal 2
T3 to terminal 5

SA1 is the cam switch, it gets 3 wires from FR1 as the power leads (indirectly from the 575v 3 phase power source)

by the diagram SA1 is wired like this
SA1 switch terminal 1 has motor wire 1 attached
" switch terminal 7 has motor wire 2 attached
" switch terminal 12 has motor wire 3 attached
" switch terminal 1 has motor wire 4 attached
" switch terminal 6 has motor wire 5 attached
" switch terminal 13 has motor wire 6 attached

it all appears to be like you said above

Just a FYI
you'll need to see if the transformer has different(high voltage) taps for the 24v control system
the diagram is for a 380v 3 phase system but your drill should be wired very similar,
but the transformer needs to be set to correct voltage or magic smoke will soon appear.

 

[Ulma Doctor]

i'm not seeing a transformer, is it hiding behind the circuit board?
can you give me a clear picture of the board while you are at it?
