Motor Wiring

If two of the four pins are ground and neutral, I'm not sure that your motor is a 240 V motor. If it was a 240 V motor, the other pins would have to be +120V and -120V or opposite ends of your power feed (i.e. secondary of the power xfmr). If it is a 120 VAC motor like a fan motor, it should be listed on the motor itself.

First, I would take a good look at the label on the motor. If it is a two speed motor, the wire colors should be identified. If it really is a 240 VAC motor, then the control circuit is doing something like switching between half or all of the windings to achieve the two speeds.

Thinking about how easily this could be mixed up during manufacturing, the only effect is that you have the speeds reversed. If you are not convinced, try looking for a Balboa representative somewhere you can call.

Definitely 230V, Here is the label: http://www.google.com/imgres?start=458&safe=off&client=firefox-a&hs=ThH&rls=org.mozilla%3Aen-US%3Aofficial&channel=sb&tbm=isch&tbnid=o-Oi_1aM4-G1cM%3A&imgrefurl=http%3A%2F%2Fwww.spapumpsandmore.com%2FUltra_Jet_Spa_Pump_PUULSC240258220_PUULS240258220_p%2Fpuulsc240258220.htm&docid=iH-akgozCm0TsM&imgurl=http%3A%2F%2Fwww.spapumpsandmore.com%2Fv%2Fvspfiles%2Fphotos%2FPUULSC240258220-3.jpg&w=1200&h=822&ei=_CYnU_P0Kefo2gXU7oG4BA&zoom=1&ved=0CMkBEIQcMEA4kAM&iact=rc&dur=9112&page=17&ndsp=24&biw=1388&bih=633

White is labeled "common", not neutral. I suspect that 3 and 4 are connected to different parts of the motor coil. The wire colors of the old harness are white to 2, black to 3, red to 4.

Balboa hasn't bothered to answer me yet.

I think page 20 of this shows that pin 3 is low speed and pin 4 is high speed. But, if I were you, I'd read the whole thing before proceeding. Don't know which control panel you have; some require setting DIP switches, programming, etc.

Mine is the VS500Z, but I think the pins are more or less standard. At any rate, I was able to speak to a Balboa tech support guy, shortest TS call I've ever had:

me- "I am trying to hook up a 2 speed 230 volt pump to a VS500Z spa pack."

TS - "Right, Red is high and black is low."

I think he's heard that question before. Why they left that out of the circuit diagram is beyond me. The G and C pins are labelled.

What threw me off was that the internal wiring in the old box from the circuit board to the power relays had those colors reversed.

Thanks for the prompt discussion on this, ya'll.

were you using it as a 2 speed before?

yes. The system will be exactly as before when I'm done.

an ohmmeter can verify that quickly

I was going to suggest that you just try it to see what the motor does.

Nice going with the TS. Win!!

Where are you located....not the US with a single phase 230V motor on a hottub pump I'm guessing?

I could have hooked it up and see, but if it was wrong I would have had to take the motor apartagain to swap the wires, and it's in a tight place behind the control box.

Florida, USA.

Connect it in Arizona, then.

<unsubscribes>

My motor ran cw on low and ccw on high. Blew the seals. I am sure it was a wiring problem....but I have not had time to figure it out.

Thanks for the input.

Is there a starting capacitor(s) associated with your motor Yusef?

yes, there is a cap.

Might be shot and the motor doesn't start off the in the right direction.

Direction is only variable with 3 phase motors. I learned THAT the hard way, too!

Not true.

Some single phase motors can run in reverse. Learnt that the hard way too.

Yes.

Options:

1. Connect it up and energise. If it goes BANG then there's somethong wrong.
2. Ring the equipment manufacturer, and ask.
3. Obtain a copy of the wiring diagram, and follow it.
4. Etc., etc.

"If it goes BANG then there's somethong wrong."

I've done that a time or two. My boss did not appreciate my methods for some reason.

(Sometimes there is no diagram, making it infinitely more interesting! I spent several weeks once trying to troubleshoot a machine that made steel fenceposts, rolling, welding and cutting from rolls of galvanized steel. It was a collection of several 3 x 3 boxes full of relays, no solid state parts. This was around 1980 and this thing was probably 20 years old then. Nowadays it could be made from an arduino and interface board. It had been repaired, modified and otherwise tampered so much over the years, that we just threw away the original blueprints. I was still wearing my TI LED watch then, too!)
