I purchased the Heidenreich and Harbeck V630 lathe at auction recently. No history about machine. It was wired for 480 volts and I have changed motor and control transformers to 240 volts. I can not get the machine to run when pushing the on button. The coolant pump contactor clicks but does not stay engaged. If I push the main motor starter in manually it starts the main motor. There are a whole lot of wires going from the electrical cabinet to under the head stock, that I do not know their function. Does anyone know where I could get a schematic for this lathe? The number on the bed is V630 801038-0262.The controls run on 110 volts and I have that coming out of the control transformer. A manual for this machine would also be helpful. I am a new member that has spent a lot of time reading this forum and have been impressed by the knowledge of the members.
