Bridgeport BOSS 6 transformer

[Jonne]

Hello!

I need connecting instructions different input voltages for BOSS 6 stepper
transformer. Have anyone?

Here's schematic (Tranformer T2. Can be seen top left of picture):

I'm changing from 460 to 230 on my boss 5(I think its the same), and will post details when I get it running (should be a week or so- may as well make sure its right before posting!). You'll need to change the control transformers also (I have 2), as well as the spindle motor wiring, new main fuses, and new heaters for the spindle overload relay. These guys have the heaters:

but I got mine on ebay, ebay also for the fuses.
will post when it runs.

the diagram is posted on another thread here (scroll way down- it is a good pdf file- I had a very poor copy that would not scan):

if going from 460 to 240 you need to move the links on the other 2 small transformers from the 2 center contacts so they connect like this:

for 460 v:
0 0-0 0

for 230v
0-0 0-0

you only have to loosen the screws, the links pivot to attach.

could you tell me what it says on the tag for voltage in and voltage out on your t2 transformer? (the big one with 3 windings in the top part of the rear cabinet).

thanks
