No takers?
OK...

A word of advice do not purchase APS/DDM Novastar used equipment and expect that the the manufacturer in it's most recent incarnation will want to support the product without asking You to part with major moneys up front.

They call it registering the machine with new owner.

Basically just a grab for money ( USD1500.-- ).

This fees is more than the price of the machine.

Anyway that's my bitch for the time being.

Back to real life.

This being a piece of American made equipment I need some advice on mains power line colour coding.

Machine runs on 220V and the mains cable has a green earth wire connected to the machine frame and a black and white wire powering the machine.

Is the white wire Active or Neutral in this setup?

If it's made for use in the US then the black and white are both active (hot) relative to ground. i.e. 120v from black to ground, 120v from white to ground, and 240v black to white.

Dan,

Thanks.
I have inspected the wiring and will need to do some re routing but in general it is quite straight forward.
Machine uses three solid state relays to control power to the zones. The final outcome will be an imbalanced 3 phase load but the individual phase burdens will be limited to 1.8kW; a pleasant reduction from 5.4kW in case of single phase configuration.
The figure of 1.8kW is peak during oven start up and periodically as the loading on the oven changes and oven losses need to be compensated.

Update

Oven converted to 3 phase operation
Still having some issues with the LCD electroluminescent back light.
Pick and place machine up and running.

I've been told 3 different prices for registration on 3 different occasions -- $1500, $1600 ,$1800. A bit understandable as a new owner will re-ask a lot of setup info, but maybe $100? Either way, they said after that they probably won't be able to help much since it's an older model and most prob won't even have parts for it.

But what are you looking for specifically? I know how to operate mine, so perhaps I can help.

And yeah... the controller on mine died recently, so I'm converting to 3 independent PID controllers, and will later tie those, as well as the front buttons/LCD together to an Arduino (or other) controller as the PID controllers speak RS485.

Ucdude,

Thanks on the offer. So far so good. I have converted the oven to 3 phase415V operation and it is giving me good results.

The controller is a Z8 based unit without an external printer port capability and without the logging ability with the fourth temperature probe.
Later controllers came out with a printer port and temperature profiling and logging capability. I take readings manually with a stop watch and so plot the temperature profile.

There may be a second hand controller on offer in the states. An oven was being wrecked, sold off for parts.
If interested say so and I shall pass your contact details.

Should You go the PID way make sure You investigate coupling between zones and accordingly modify set-points for the three zone to account for the inter dependencies.

Good luck with the effort.

Maybe you could use one of these Iggy.

oops... temperature range is too small.

Nice unit...

Pity it does not cater to a thermocouple sensor
