Wiring an MEM starter for 240v Lathe

When in the workshop today I took the opportunity to remove the cover from my MEM starter and inside of the lid was what I was hoping to find instructions relating to the use of the starter on a 240v supply/load ! There as been a lot written on how the starter should be wired when on 240V so here's what MEM say should be done, sorry about the pic's quality.

Presumably it has a 240v coil and not a 415v type

Yes Geoff

Out of interest, as some one mentioned 240 or 415 volt coil, I found it quite easy to remove about 40 % of the turns from a 415 volt coil to then use it as a 240 coil. MEN coils are easy to remove and replace.The coil former "hole" is square shape so I made simple wooden mandrel on to which I mounted the 415 volt coil, I run between centres quite slack loose fit NOT UNDER POWER and removed lots of turns about 30%. After a while I rigged up a temporary start/contactor connected it to 240 volts and checked if the moving assembly would pull in as normal.When it does, I taped up the coil and leave it on test for an hour or so. Some coil are mass impregnated, they need to be very hot to loosen the resin, don't put it in the domestic oven. Also its not to difficult to strip out a former and rewind it on the lathe, providing you can souce the right gauge of wire. Ted

Well... it's done!

No machine tools were harmed in the wiring of my switch box.

The overload has been adjusted to 2 amps and the 0 volt cut out works.

The wiring confused me due to the fact that someone had connected the coil for remote switching. My brother in law worked through it with me last night and today I connected it up. I now have a safer workshop.

Thankyou guys for your input..
