Evening guys. I had replied last night but cant see my post anywhere. Dont know whither it went on or not.
Just for info this starter and motor were used together it started and ran without issue. Since then they were disconnected and not marked so i thought the problem to be a wiring mixup but i cant see how else is could be connected using 5 wires. It was definitely connected to a single phase line neutral 230v supply before. It could be that the load was less so this issue didn't show up? The motor and starter are now on a different mill, but it looks very similar in size with pulleys the same size.
today i started the motor by spinning the mill slightly first then starting it. When it is up and running it is doing 1490rpm with the mill running. So pretty much spot on what it should be.
I removed the belts and started the motor to prove the centrifugal switch. I tested between bottom right terminal and A3. Which is closed circuit at startup then open circuit when it reaches speed. I can actually hear the switch open.
This could be useless info but the cables disappearing into the motor are in sleeves cables z2+sw go in the same sleeve an head towards the fan end of the motor. A2+A4+z1 go in a sleeve towards the front of the motor. The rest appear to go in another sleeve.
i did the resistance tests with the supply cables disconnect but have left the paper in my jacket pocket. I will post these readings later.
hope that makes some sort of sense.
