Author Topic: Kelmar Failsafe to Component Engineering Automation Wiring Matthew McBride Film Handler Posts: 97 From: Tupelo, MS USA Registered: Oct 2011 posted 01-19-2014 02:45 PM                     I recently got a Kelmar 2335/3H 3-7 cue detector and I want to use it with my current automation, the CE TA-10 automation. Looking at the diagrams I wasn't quite sure how to wire it. Has anyone done this or know how to do it? Thanks.  |  IP: Logged Robert E.

I DO have a fail-safe but it's not attached to anything so I by-pass it. Frankly, I like it this way. The only thing that would be better is a two projector change-over system.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 01-19-2014 03:47 PM                     The failsafe should at minimum be connected to shut down the projector if the takeup fails for some reason. Even my manual changeover setups all have that bare minimum feature. The use of actual cues are purely optional, but you will agree the first time you walk into the booth and find a mile or two of film piling onto the floor.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 01-19-2014 07:33 PM                     As far as failsale there is no electrical difference between the CE detector and the Kelmar. Both provide N.O. or N.C. contacts so it just depends on what your automation requires. The CE cue detector works via a relay and the Kelmar via a microswitch. Between the two the Kelmar cue detector wins hands down but today's microswitchs are very flakey and don't last as long as the old ones with cadnium in the contacts do.

So basically I'll just have to figure out how my automation is setup to wire the cue detector part up, this is what I gather.  |  IP: Logged Ed Inman Expert Film Handler Posts: 103 From: Jackson, Mississippi USA Registered: Jul 2004 posted 06-09-2014 07:30 PM                        Reviving this topic for a moment, is there a reliable product, lacking a full automation unit, to wire a failsafe to shut off the motor (when one or both arms fall) without running the full AC load of the motor through the tiny microswitch? A relay switch of some sort? Thank you in advance for any suggestions.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 06-09-2014 09:21 PM                        Yes, we provided a 12 volt transformer, suitable relay and a switch to do that in drive ins. (6 volt on XLs so that you could use the same transformer for the projector lamp bulbs).  |  IP: Logged Sam D.

I bet Louis has one somewhere.  |  IP: Logged Ed Inman Expert Film Handler Posts: 103 From: Jackson, Mississippi USA Registered: Jul 2004 posted 06-10-2014 09:36 AM                        Yes, that sort of setup sounds exactly like what I'm looking for. Any leads appreciated.  |  IP: Logged Ed Inman Expert Film Handler Posts: 103 From: Jackson, Mississippi USA Registered: Jul 2004 posted 06-10-2014 08:00 PM                        As an addendum, I took a closer look at my switch that failed and it was only rated at 3 amps. Until I can get a better automation system I'm going to try replacing it with the V3L-2102-D8 switch rated at 10 amps. Hopefully that one should hold up better under the load of the motor. I'm also thinking about connecting a bell to the "live" terminal when the handles drop as an extra safety precaution.  |  IP: Logged
