5. Check that the dimmers are set for the correct control input. Check the dimmer status LED to see if
it indicates a valid control input.
If they do anything else:
1. Put in a DMX termination plug. Try an opto-isolator. Try moving the console to the dimmer and
connecting the two with a short DMX cable.
2. Swap cables and circuit cards one by one to see if the problem follows the part.
3. Examine the console for signs of abuse or damage, particularly the sliders. Sliders that feel gritty
are responsible for flickering on that channel.
4. Examine the control cables. Check that they are continuous, undamaged, and wired correctly. Ring
them out to be sure.
5. Check the power input wiring on the dimmer packs.
6. Check the load output wiring.
7. Dimmers that do not dim usually have shorted triacs or solid state relays. The dimmer will have to
come in to have the part replaced.
