Author Topic: Kinoton FP30 stopping Sally Ann Burgess Expert Film Handler Posts: 120 From: Queenstown, New Zealand Registered: Apr 2008 posted 09-07-2011 06:37 AM                     It started when the projector stopped while the film was on. The film break alarm didn't go off. Now, every other show, the projector starts up, then stops, the film break alarm goes on then off then on full. I have swapped the film break relays with another projector's but the problem persisted. Today I took out the two IA6 motor start relays and put two spares in (used)...and now the projector as well as stopping, has had the dowser go up during the film! Has anyone else had this problem? I can only think now it must be a dodgy film break microswitch?  |  IP: Logged Ian Freer Expert Film Handler Posts: 135 From: Wellington, New Zealand Registered: Oct 2003 posted 09-07-2011 07:12 AM                     Hi Sally Is this an older FP30A with the Red Roller or a newer FP30D with the IR film detector?

But the film break knob is red. (the part I pull out when threading)  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

It is a little hard to diagnose without knowing the specifics of the vintage. The switch that the failsafe roller connects to is a suspect and so is the motor holding relay (Re2 in modern projectors). A lesser suspect and one that you said you changed was Re1. Don't forget about the platter either...if you have a Kinoton platter (or others can do it too)...there is a film break circuit/wrap detector circuit that can also shut the projector off. -Steve  |  IP: Logged Tony Bandiera Jr Film God Posts: 3067 From: Moreland Idaho Registered: Apr 2004 posted 09-07-2011 10:29 PM                     Steve is on the right track...replace BOTH of those relays with new ones, not used, especially the ones from Kinoton. Those relays are especially dodgy, a serious flaw on an otherwise great machine. I just bought a full set to replace the ones in one of the UC Irvine HIB100 projectors, I got the NTE equivalents, they were about $7 each. I'll try to find the paperwork and get you the part number. If you have a good electronics store near you (NOT FRYS or Radio Shack) they can cross reference one of the originals. Oh, and I disabled those hideous red roller film breaks by loosening the bracket and swinging the reed switch out of the way.  |  IP: Logged John Wilson Film God Posts: 5438 From: Sydney, Australia.

Of course, at the end of the film you're going to have to turn the motor off yourself or change the automation to have it do the job. The switches are readily available.  |  IP: Logged Sally Ann Burgess Expert Film Handler Posts: 120 From: Queenstown, New Zealand Registered: Apr 2008 posted 09-08-2011 02:09 AM                     Thanks guys I have replaced the dowser relay now just to eliminate those relays as the cause too but still the projector kept shutting down. When I restarted I pulled the film break towards me a bit more than it was already, and it was fine. I have noticed though that the red knob alun screw in the centre is extremely loose. No matter how many times I turn it, it isn't tightening up. In order to bypass the film break, would I just have to disconnect the microswitch at the back...stupid question I guess but I've never done it.  |  IP: Logged Jean-Marc Toussaint Film Handler Posts: 60 From: Paris, France Registered: May 2008 posted 09-08-2011 05:21 AM                        I've done it on one of my machines, no big deal. It's a very simple job. We're not using the feed and take-up on the projector. In case of film break, the transport system (vertical tower) has its own failsafe system that will shut everything down.  |  IP: Logged Sally Ann Burgess Expert Film Handler Posts: 120 From: Queenstown, New Zealand Registered: Apr 2008 posted 09-08-2011 07:11 PM                     Well one of the small film break microswitch screws at the back of the projector was a bit loose so I tightened that up. The next show was fine, I have a spare microswitch on standby...not that my soldering skills are too flash!!  |  IP: Logged Jarret Chessell Master Film Handler Posts: 288 From: London, Ontario, Canada Registered: Jan 2009 posted 09-09-2011 10:13 PM                     Do you have a device in there like a motor controller (variable speed controller). I've had similar issues with a motor just winding down during a show for no apparent reason.  |  IP: Logged
