A local middle school is putting on a production of Willy Wonka, and, since one of the directors knows me very well, I have been asked to help them sort out their sound and lighting situation. I have little experience with theater lighting, only the two basic systems, which I can not even recall the make or model, that were in my high school but I tend to find myself very handy with figuring out electronics. The following is my guessing based on my readings of different posts throughout the internet. The system has 2 Electro Control Playmate dimmer packs. I was able to get these to power up aftering having the ISD electrician replace the main fuses. On the front of each Playmate, there are 3 places to plug in fuses. I only have a total of 4 fuses meaning I can have 2 on both or 3 on one and 1 on the other. There is a small switch on each Playmater label Test with positions seq, on, off. By placing this on seq, the lights will all cycle through, I assume testing each feed to make sure it works, and of every one they come on, so I know that power is getting to the lights and that the dimmer packs are communicating with the lights. There is also a Electro Controls Celebrity board. From my readings, both the dimmer packs and board use ECMux protocol so they should be able to work together, and I assume they were the original pieces. After some hunting, I found the hold on the on/off key, of course in some far off office and I was given several keys and instructed to "find the one that works, just try not to break the other ones, they must go to something." I am able to get the board to power up and have even figured out how to set and delete the x/y presets and stage record buttons. The only problem is that the faders have no effect at all on the lights. I have the Master slider, the Independent Masters, the Scene Masters, and all scene faders on and there are not lights on. This is with the Test switch set to off, which I assume is as it must be. I have also tried with the switch set to on, seq, and all different combination of settings for the faders. I am unable to get any of the lights to respond. One of the things that doesn't make much sense to me is there is only one cord coming out of the Celebrity board, but I have two Playmates. I'm not certain if these are wired together so they communicate with each other or what. I have tried all possible combinations of getting the board to the dimmer packs to no avail. If anyone has any information on how to get these lights to respond to the board I would greatly appreciate it. Thank you very much.
