I got my 'new' CVA lathe in its intended spot last night, with this evening allocated to get the electrics sorted. These things weigh 1.5 tons & the electrics are all behind a door at the back, so I want it right before it's hidden by the other lathe which will be backed up to it. My heart sank when I read the label on the panel "control voltage
240V" . That means the contactor coils are 240V, so it needs a neutral, but my 3-phase comes from a converter with no neutral, & the wiring is all 3 phases plus Earth, to 4-pin sockets :-( I've either got to change the contactors (3 of them!) or find new coils for them (unlikely) or rig up a 240V supply. I reckon my best bet is to fit a small transformer to the board to give me 240V from two of the phases, it only needs to be a few VA to run the coils, but where to find one? Ideally with a few tappings to get the voltage right, as some contactors are fairly fussy about voltage. The whole job of shunting the workshop around has to wait now until I can sort it. I know I could run another cable in from a 240V socket, but it's messy and there isn't a socket near the machine Andrew, have you got anything in your clearance mountain? How have other people got round this problem, I know it's not all that unusual to have 240V controls on 3-phase stuff?Cheers Tim
