Got a couple of problems with some of our Kinoton PK60D's. On one of them, the aperture plate won't budge! It is stuck in scope. I know how to remove the plate itself and move it over manually, but why do you suppose the aperture changer won't move at all?On several of our machines, the "pad shoe" (that's what it's called according to the manual) will not spring all the way back against the sprocket. It stops about a 16th or an 8th of an inch from the sprocket. This has happend to both upper and lower pad shoes on various machines. I read the manual on how to remove the pad shoe, and I take it that there is some sort of spring in there that has to be aligned correctly. Could these springs be wearing out and need replacement, or is it possible that somehow they just got knocked out of alignment?

With a nice specific question about a projector as new as the Kinoton PK60D you want to speak to the North American Distributors for Kinoton or specifically Larry Shaw at Boston Light & Sound.Larry Shaw

Hello Ken,
most likely, the motor driving the aperture plate is gone. It could also just be dirt inside the tube in which the guidance arm is running, but that is less likely.
As for the "pad shoe", that happens sometimes with Kinoton projectors. It is sitting on a spike which is secured by a little screw on the front side (i.e. facing the screen) of the unit (I don`t know what it`s properly called in English)which presses the shoe against the aperture area. Sometimes that screw loosens or even falls out. If it is loose, you can readjust the height of that spike by turning it (the spike), then fasten the screw again to lock it in position. The spring is for readjusting the force with which the whole unit presses against the aperture. It is controlled by a small finger-thick wheel on the front side of the projector.
As you mentioned the PK60 manual, it struck me that among the wealth of manuals available on this site, there are none from Kinoton. Why is that so? All Kinoton manuals are available in pdf-format.
Greetings
Michael

We are awaiting approval from the Kinoton folks regarding the posting of their manual library.

To whom have you talked? If you want, I could directly ask our friends at Kinoton headquarters in Munich.

I requested the permission through Larry Shaw and the gang at Boston Light & Sound.

Hello Ken, the pad shoes have a screw behind them that sets the pads position relative to the sprocket. Have you checked it?
Aperture plate changers. Either the motor is dead or the controller is dead. controller mounts above the assembly.
Could also been the control wiring, done a voltage check to see its getting power?

I've never had a pad shoe stay open but I have had them close too far. The other end of the pin that you use to open the shoe has the adjusting screw that sets the shoe clearance. Make sure it is hitting it's striker. Then adjust the hight for two film thicknesses (in a pinch just set it to clear the sprocket...turn the unit over by hand and listen for any rubbing.As to the tension of the shoe...there is a tool included with projector to allow you to adjust the tension. Look in the parts kit and look for the metal fork thingy that most people can't figure out what it goes to. It is a spanner wrench. The "fork" end will engauge the nut the tensions the spring and leave you room to get your (also supplied) hex wrench in there to loosen/tighten the locking screw (in the middle). However, I must admit I have yet to have one of these shoes loose it's tension. Some seem to come with too little or too much tension (there are actual specifications somewhere but I do it by feel after all these years).

Thanks guys. I'm not actually doing any of the work, our tech is taking care of it. I was just very curious as to what the problem could be. I haven't even meet our tech yet, but when I do, I'll ask him.
