Author Topic: Adding Interlock Hold terminal to Maxi 8x Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 05-28-2007 05:03 PM                     Am installing a pair of Kelmar 9700 interlock boxes on Maxi 8x's for a customer. Need the INTERLOCK HOLD terminal on the Maxi 8 which these earlier Maxi 8x's don't have.. and the 9700's instructions are pretty vague... it just says the Maxi 8 can be modified for this. How do I modify them and add this function to an open terminal?? Thanks, Mark  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 05-28-2007 08:11 PM                        Do you have later drawings?

Neither one shows it. Terminal 4 is unused so I would assume I run a wire from there to some point in the unit?? Mark  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Last I checked, Kelmar made up new drawings that were converted to pdf for these older units.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 05-29-2007 06:53 AM                     I did... all thats there is Kelmar and Christie AM series drawings. I'll call Thomas in a while for the low down on the mod.

Many of our Maxi drawings are hand drawn, on large (C and D size) paper, and can't be converted to pdf easily.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 05-29-2007 02:57 PM                        The only Maxi 8 drawing I have that shows a hold circuit is dated 2-9-82 revision. This one has terminals labelled 1-22 ans 23-44. #33 is labelled "Hold for alarm and interlock." The wire goes to K3 show off relay contact and k6 failsafe contact. The blueprint is approx 24 x 36" Drawing 1058. Do you need a copy?

John... you should be out roaming the desert in your Land Rover if you're on Vacation . I called Tom at Kelmar this morning and he faxed me the all the do-do. It involved adding a DPDT 12 vac relay externally which I've done to both units. All is now working well in interlock. The end result is certainly a kluge . I also had to rob a cue during interlock since all three available cues were being used for other stuff. So I added yet another relay to switch the center cue away from screen lights up at show end and diverted that cue to put the automations into show mode. This happens when the 9700's are turned on so its invisible to the operators running the stuff. They leave the screens off anyway because of pre-show, not sure why they even have screen lights . I have to install 2 more of these 9700's next week on AM5's but already have that worked out. Thanks again! Mark  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

The AM5 was decent enough though.  |  IP: Logged
