PowerPro - good news

[nuhobby]

Let me be the First to Thank Shopsmith !!!!:)

The irony is I may not have enough time to work on this over the Holiday weekend.

Here are some pic's of what came through FedEx today. This is the self-upgrade option.

Just Unpacked:

Power Electronics Module (will mount in middle of machine):

Control Panel. The PCB on it definitely says Teknatool:

Wow! we even get a binder with the instructions!!! Good for you, Chris! Don't fret! Family comes first!

I like the notice on the seal for the electronics module.
They want to make sure you don't release the magic blue smoke.

Your a lucky man nuhobby......a very lucky man. Good luck and congrats!!!

I managed to get in about 3 hours of installation work tonight. And I had already done the major disassembly part of the original headstock a few days back.

So.... now It RUNS!

Some minor observations of mine in case they help the next folks:
(1.) Wire dressing is absolutely essential throughout the installation; the instructions are plentiful for this. Because...
(2.) The headstock is *packed*. Really hardly any room left in there now!
(3.) Electrically -- The electronics apparently has a huge storage capacitance in it. After you turn off the main (headstock) switch, the digital control panel stays lit for quite some time before it bleeds down.
And -- I suspect something about that large capacitive circuit affects the apparent behavior at a GFI (ground-fault-interrupt) outlet. When I first plugged in the PowerPro, everything started lighting up but then my GFI tripped. After repeatedly checking with ohmmeter and visual inspections, I really could find no short-circuits, but maybe the capacitive transient current is contributing to this 'bleed to ground' (?). For now -- I did a temporary hookup without the ground lug, and everything RUNS. Really quite slick!
There is some remaining adjustment to do to find the optimal balance of the 2 belt-tensions working on the idler pulley/shaft; instructions are provided. But -- I've put in all the time I can before family stuff this weekend.

Good luck to All!

You may be right about the capactor to ground blowing you GFI but I would not bet on it. I suspect one of two things. "A" you GFI is bad sure it is a coincidence that doesn't seem likely or "B" you do have a wiring error. Before I chalked it up as "normal" I would double check with SS to see if they have heard anything about GFI's tripping with the new setup. I don't think so because I think this would stop them from getting UL approval. My guess you have a problem.

You need to be checking for high resistance leakage, not shorts. 24 thousand ohms will create a 5 ma leakage current which should trip a GFCI.

If you are able to measure AC current in the 0-10 milliamp range, measure the current flowing through the grounding conductor(green wire).

GFCI should trip at approx 5 ma.

I be with Ed! Look for a cause!
