Let the fun begin !!! ???

Initially i was not going to use a resistor because of the drivers draining as pointed out. i've read a lot of posts that discuss this and i know a lot of the experienced`builders don't bother because of the reasons stated. but i will be using a relay in the e/stop circuit anyway and it will have an empty N/C contact available so it's an extra terminal for the resistor and an extra piece of cable to hook it in. i think that's all that's required anyway? if i don't use it i will definitely integrate the fault relays and enable signals as Eddy suggested. on another note my toroidal coil arrived friday. i should have the cap and bridge this week, hopefully. the coil has 3 windings http://www.airlinktransformers.com/c...nge/CM0625225/ the colours are as follows: coil 1 BROWN / BLUE 1.6 ohms
coil 2 BLACK / RED 0.5 ohms
coil 3 YELLOW / ORANGE 0.5 ohms
so i assume from this that the following
Coil 1 = mains supply 230 vac
coil 2 = 25vac
coil 3 = 25vac
and if i join BLACK and YELLOW together power up and meter across RED and ORANGE i should get 50 vac OR 0 vac . a change of the secondary coil arrangement if i read 0 volts. i will try it tomorrow to see.

Recently bought one of the Airlink trafo's. Join black/yellow together and red/orange will give you 50v AC or there about.
