Author Topic: A different Westrex Problem William Phillips Expert Film Handler Posts: 117 From: Cardigan, Wales, UK Registered: Feb 2002 posted 06-06-2002 01:39 PM                        Does any one have out there a circuit diagram for Westrex Towers, I have absoultly no idear what model tower it is there are no markings on it. I want to get hold of the diagram for the run/rewind/off selector switch (the one that looks small and easy on the front, until you take off the covers and its the size of the regulac transformers and has got about a million wires coming off it). The switch has got a bad contact somewhere. I dont want to touch the thing until i`ve got a diagram just in case. Any help would be appreaciated  |  IP: Logged Ben Wales Jedi Master Film Handler Posts: 602 From: Southampton.

They are A3 so I'd need to get them reduced for scanning, which is going to fuzz them up a bit. Those switches are no longer available. You have to replace it with a modern equivelant, and of course the pin outs don't match I literally wrote the book on replacing old with new, when I get back from my holiday I'll dig it out and see if it's any help to you. What's the tower doing / not doing? It's not always the switch at fault. A sure sign of switch failure is that it suddenly develops more than three positions, and all kinds of wierd things start happening, both top spools running together is one example!  |  IP: Logged William Phillips Expert Film Handler Posts: 117 From: Cardigan, Wales, UK Registered: Feb 2002 posted 06-07-2002 01:28 PM                        Pete the only thing thats wrong at the moment is that ocasionaly turning from off to run front, rewind rear some times the take up wont come to life, switching off and on will cure it. Its had new caps, motor`s been loved by your office and the toggle switches have been changed.  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 06-07-2002 04:34 PM                     Hmmmmmm, So it's only on run front rewind rear that this happens? If so I think the rotary switch is to blame. If it was both settings then I'd be looking at the take up variac and it's carbon brush.  |  IP: Logged William Phillips Expert Film Handler Posts: 117 From: Cardigan, Wales, UK Registered: Feb 2002 posted 06-08-2002 09:46 AM                        I should of said that there is only one side to this tower as it is mounted horizontly due to the lack of head room in the projection room. So all rewinding and playing gets done on the one side. The one good thing is that I`ve got an extra bench because of it ( well on it anyway). The tower has also had new carbon brushes.  |  IP: Logged
