Well, lets start at the beginning. In your
dimmer rack at the center is the control module or
CEM. This is where your reset
button is. The
CEM has an
LCD display that will give you information about the rack. Any serious errors will also cause the beacon at the top of the rack to flash. On the right
hand side of each
dimmer module you should see a pair of green LEDs next to the word "Signal." When you turn on a
channel at the board, whatever dimmers it controls should have that
LED lit.
Next time you have this problem where the lights don't come on, do this:
1) Check to see if the dimmers that should be on have a green signal light
2) look at the
LCD on the
CEM and see what it says.
2A) If it says "rack errors" push enter (the check
mark button) and it will display them. You can scroll through the errors with the up and down buttons.
2B) If there are any errors, write them down and tell us (or
call ETC and tell them)
3) Inside the door of the rack are two air filters, check them to see if they are clogged. If they are clogged, clean them out!
4) When you turn dimmers on, make sure that the rack fans are running.
Also, just for info, look at the numbers to the left of the dimmers, do they go in order or do the go: 1, 2, 7, 8, 13, 14....?
If you can, take a couple pictures of your setup and any error messages and post them, it may help. Also, if you know who installed the
system it may be worth giving them a
call, or
call your local
ETC dealer. Once again, don't hesitate to
call ETC Tech Services!
