    ETC Sensor™ SP6 packs don't like me. I've never shown them anything except respect, but somehow we have issues together. I get along fine with SR24 and SR48 install and road racks and have never had a disagreement with an MPE. Anyhow, today during class I had a problem and was lazy and called ETC Service. Turns out the CEM in my 12-pack thought it was a 48 rack. Most likely someone in the shop thought one could just swap CEMs. In less than 10 minutes, Tracy had solved my problem, and talked me through the process of allowing the CEM to discover into what kind of rack it's inserted. I could have looked it up in the PDFs myself, or posted a message here, but I wnted an immediate answer, as lunch was almost over.

    Here is the rig I used:
    [​IMG]

    My goal for the class today was just to get people to know what all the parts of a lighting system are called, and a little about how they plug together and why.

    The picture above shows (top, L to R) S4-PAR VNSP, VNSP, NSP, MFL, WFL, XWFL. Below are 410, 414, 419, 426, 436, 450, and VL2500Spot. On the floor is a VL24042, a 4552 bar, and my LED ParCan.

    I think it was a pretty good training rig, to show people the differences and similarities and a little about photometrics.

    Feel free to point out all the flaws in the picture.

    The orange extension cord is what the shop provided for the item listed on my Shop Order as "25' Edison cable." I used it to plug in my 0.03A LED ParCan.

    Even though the cable can handle that, does it comply with code for theatrical use? This is for training right?

    Alex, you have a valid point, and I explained to the class that, like duct tape, orange extension cords are generally not allowed in the building, along with AC Ground Lifts and CubeTaps. I need to put together a "List of Forbidden Devices", to post next to the "No Firearms Allowed, without prior written permission from Security" signs.

    What board did you run that off of?

    What if the orange extension cord is 12awg or 10 awg? I have lots of orange extension cords but they are at least 12 awg.

    My Pocket Console®, of course! The six-bars were Soca-tuferred, so it was 7 channels. Really wanted an Ion, but that will have to wait for the "Controls" class.

    With NEMA 5-15 connectors? Was this a voltage drop thing, extra long cables?

    ****! how are you going to go about hanging a VL2500 in that manner! Chesboros are strong but you should still of used at least two and made a triangle to prevent it from falling!

    LOL, this will end well. I know you are a noob and don't really know the forums well, but derek is pretty up there as far as experience and well respected on the boards. You probably shouldn't start your posting here by criticizing other people.

    Thanks, [user]Pie4Weebl[/user], but [user]NFazio[/user] has a vaild point. I should have used a forged steel rigid cheeseborough, but all I had was an aluminum rigid double coupler. (Though I fail to see how one can make a triangle out of "used at least two and made a triangle.") The unit could not fall, as it was safetied to the 10' cross pipe of the goal post. (Through BOTH handles, as per Vari-Lite's recommended practices.)

    Thanks for noticing, [user]NFazio[/user]. You're the first person who's mentioned it, including the class members. And rest assured, had the fixture been for a show, or were any higher, I would have done it properly.

    I always preach "Steel 'burgers for iron pipe; Aluminum 'burgers for truss and tube!" but don't always follow it myself. My bad.

    Another ETCP Certified Electrician? Or does that fall under rigging? :mrgreen:

    Just kidding. I do think Derek had a handle on the situation though...

    Hey... I just have to say that what you have set up here is almost identical to the setup ETC has at their plant for demonstrations. I went there with a local theatre's school of the arts and sure, their setup was a little more permanent... but still. I'm sure you covered a lot of ground well with this!
