Author Topic: Cinemeccanica MUT - Speed Control Chris Byrne Expert Film Handler Posts: 102 From: Kirwan, Australia Registered: Jan 2003 posted 12-01-2003 06:19 AM                     Recently I had a problem where the MUT was over-energising when I switched to break down mode (it was fine on Make-Up.) By over-energising, I am referring to a sporadic spinning of the right hand spindle when power was applied to the MUT. To cut a long story short, I replaced the speed control PCB inside the MUT and it corrected the problem. Just recently a the exact fault has happened in an auto-rewinder and so I have ordered a PCB to replaced the faulty one. Has anyone experienced these faults or have a fair idea of what component may be faulty on the board? I initially thought it could be the pot, however the make-up circuit was working fine. It is a Cinemecannica TA35 MUT and the board in question on the auto-rewinder is CinAM615 PCB.  |  IP: Logged Mark Hathaway Film Handler Posts: 31 From: Australia Registered: Nov 2001 posted 12-05-2003 11:06 PM                     Hello Chris, the MUT control card uses relays to switch between make up and brake down. If it was miss behaving only on break down, or visa versa, I'd think it would be the trim pot that is intermittent. The trim pots are next to the sliding pot. BTW, There are so many different versions of the MUT controller. Cinemeccanica seem to release a new MUT pcb design with every batch they make.  |  IP: Logged Jean-Michel Grin Expert Film Handler Posts: 222 From: Geneva & Lausanne, Switzerland Registered: Jul 2002 posted 12-08-2003 07:47 AM                        We experienced the same trouble on somes "normal" Cinemeccanica film rewinder. The only solution was to replace the entire pcb or switching the power "off" to prevent the spinnin. <Right or false?)

And every time the PCB came with a new circuit modification!!! Bye A  |  IP: Logged
