Guys can anybody help with some dol starter wiring?, I'm not great at 3 phase motors

I'm wiring a bottle crusher , it came with a eaton mem 28ADS1X dol, it says 230v coil but the plug to the motor is 3phase and earth

The mem dol is knackered and the guy who gave it to my mate supplied a Crabtree motorpak 24MR again 230v coil

I've held in the contractor manually on the old eaton dol and the motor runs well, I'm after help with the Crabtree wiring as the terminals are different between the two starters

The eaton had a 17 and 18 for start which is a little clip on start button, the Crabtree just has 13 and 14

I can't work out how the 230v coil can be utilised without a Neutral

Can anybody help?!!
 
Cheers lads
Story is this...it's a bottle crusher for a recycling firm run by my mate, he bought it on eBay for a song, not running as the DOL was smashed in, it's 3phase no neutral , the plug from the dol is 4pin no N, we only wanted to see if it worked , he does not want to spend loads on it, so I wired in a 4 pin socket from the DB just 3m away, plugged in, and nothing just as I thought would happen, when it comes to wiring the spare Crabtree DOL I only remember certain things but couldn't not figure how the 230v coil ever worked, my suspicion is that maybe once it was located near to a 5 conductor set up
In the end I had a old 3 pole rotary in the van, I put it straight into that at when you turn the isolator it fires up fine, I don't know if this will damage the motor eventually but I know it won't do the rotary any good so I won't be leaving it like that.
Cheers for the Input

Firstly this wont do as a set-up and if you mean rotary switch straight to motor then where is your motor overload protection ... also if you have a power failure then upon the supply coming back on your motor will start up without warning i suspect with the nature of the machine this is unacceptable, if you were so close to the board and only wanted to test it worked correctly with a 240v coil on the contactor then why didn't you rig a fly lead up to give you a Neutral to the coil?
Don't leave this set up running for the customer or you may be digging yourself a very big hole you cant get out of.

Lastly be very careful you don't fall into the trap of having the cart leading the horse, regardless of how much your mate is willing to spend it shouldn't mean you should compromise on regulation and safety, the cost of fitting a new DOL starter is what it is and if doing so is to much cost then he shouldn't have bought the machine in the first place, agree do a temp' rig up to test its worth spending the money on but don't choose this temp test as a cheaper solution ...also i assume without overload protection on your motor when you tested it you clamped the phases to check its loading as without doing so you cant assume its working ok.
