Hi John Did have a vague idea what the wretched things did, just had a desparate hope someone had a schematic of the device in question. Save me the trouble of waving the Fluke at it. Just had a shufti at the motor, it is a dual voltage type, so I might just have a trip to Drives Direct, just up the road from me, if I can't easily knock it into shape. There's a couple of relays in there, one looks expensive, a Broyce 1OVR, some sort of over voltage doins ... if that's shot, then I'm not going to bother .. either get a VFD or sling the whole damn shebang out the door and get a Wabeco D6000. It's only money, and I can't take it with me, it seems ... :lol: BC |

Hi Dave I put a VFD from Drives Direct on to my Boxford very happy with it John |

Give Transwave (Power Capacitors Ltd) a call - they are a very helpful company to deal with. The usual Transwave static generates the third phase as per the diagram posted above, but also has a voltage sensitive relay made by Broyce Controls lookiing at the generated phase. When up to volts it switches out the start bank of capacitors leaving the run bank connected |

Will get Mr Wilson to nip round and swipe it ... :thumbup: Cheaper than me buying one ... :lol: :lol: BC |

Depends if that is the faulty component. I've no idea if it is, or whether it's just a symptom.. there are 3 caps in there, I have a Peak LCR meter which will give a good idea if the caps are OK, although I would think it's not a good tool to use on motor run caps. Works fine on electronicy stuff, but only gives the capacitance, not the ESR or anything useful. BC |
