Hi,
I am a parent volunteer at a public Middle school outside Boston assisting in there annual musical.
I have done lighting and sound for a community playhouse for years and have some knowledge of Dimmer theory and electrical repair.
Does anyone have access to a block wiring diagram for this model CD80?
The CD80 24x1.2Kw Dimmer packs the school have installed are Model 8327 mfg date 1994. This has the older style DMX control Board with the Thumb wheel address settings, red dip switch and clear bump buttons that I have been told indicate a Gen-2 version of the Control board.
After re-lamping their Altman 160 Fresnels and patching the Leprecon 624 board for default 1-1 DMX patch I ran up all the Dimmers that should activate Circuits 1-24. Circuits 9,14 and 18 would not light the associated Strip/Border lights via the board when connected to the Dimmer Pack when given a starting address of 001 on the Thumbwheel settings.
I re-addressed this pack to start with address 025 instead. Re did the patching on the Leprecon and all the circuits attached to this Dimmer pack could now be run up.
I moved the second Dimmer pack to DMX 001 start address and re-did the default patch 1-1 and ran the circuits back up. I now see that the same circuits 9,14 and 18 cannot be run up by the controller.
I used the Bump/Bypass buttons on the controller and found that I was able to turn on Circuit 14 but not able to turn it on using the Leprecon 624. This seems to indicate that the dimmer SSR is good on the Dimmer pack for this circuit but the control signal for address 14 seems to be getting propagated.
What is confusing me is whether it could be the Leprecon board itself but it seems very odd that individual addresses could be not operational.
Any suggestions/recommendations on how to further troubleshoot this is greatly appreciated....
I wish I had a spare dmx controller I could borrow to rule out or pin it back to the Leprecon624 board signal.
many thanks,
Pat
