Somebody asked me to take a look at input voltage connection on an old Biesse. The (hand written!) electrical panel label seems to suggest it's a Rover 321...? It has some crazy Iskra autotransformer (made in Slovenia) and another heavily configurable transformer marked "C.E.E. electrotec s.r.l. - IMOLA" which it appears are intended to make it "universal" input. There is a plate on the transformer which purports to show connections for anything from 190 to 610 volts. But it doesn't seem like these connections are complete for 3 phases.He has schematics which are supposedly for this machine, but they don't show any of the reconfiguration stuff, they just sort of show a generic transformer.Anyone have actual schematics, or understand the reconnection of this thing? At first he said we could contact Biesse, then he backpedaled on that idea... IDK why... cost?Thanks
