Helping someone get a 1994 Mazak up and going again. It was supposedly running a few weeks ago, but you know how that goes. 3 phase power into the machine is good. Green start LED on front of control is lit. Red button is not. In the back cabinet, one of the small power supplies has a red LED on it and measure 24v. The other power supply is not lit up. I believe it receives its power from the main power supply board. This board is located with the other boards in a rack style setup. This board has nothing lit on it. I measured 50 volts going into the board. On the board, it says 100v IN.

Does anybody have any information such as a power flow control chart? What about an electrical diagram for T-plus control. Where does the power supply board receive its power form?

Thanks for the help!
