Following are a few common problems that may occur during operation. Here are some
suggestions for easy troubleshooting:
A.
The fixture does not work, no light
1.
Check the connection of power and main fuse.
2.
Measure the mains voltage on the main connector.
B. Not responding to DMX controller
1.
DMX LED should be on. If not, check DMX connectors, cables to see if linking properly.
2.
If the DMX LED is on and no response to the channel, check the address settings and DMX
polarity.
3.
If you have intermittent DMX signal problems, check the pins on connectors or on PCB of the
fixture or the previous one.
4.
Try to use another DMX controller.
5.
Check if the DMX cables run near or run alongside to high voltage cables that may cause
damage or interference to DMX interface circuit.
C. Some fixtures don’t respond to the easy controller
1.
You may have a break in the DMX cabling.
2.
Check the LED for the response of the master/ slave mode signal.
D. No response to the sound
1.
Make sure the fixture does not receive DMX signal.
2.
Check microphone to see if it is good by tapping the microphone.
