5. Troubleshooting
Following are a few common problems that may occur during operation. Here are
some suggestions for easy troubleshooting:
A. The unit does not work, no light and the fan does not work
1. Check the connection of power and main fuse.
2. Measure the mains voltage on the main connector.
3. Check the power on LED.
B. Not responding to DMX controller
1. DMX LED should be on. If not, check DMX connectors, cables to see if link 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 unit 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 units don’t respond to the easy controller
1. You may have a break in the DMX cabling. Check the LED for the response of the
master/ slave mode signal.
2. Wrong DMX address in the unit. Set the proper address.
D. No response to the sound
1. Make sure the unit does not receive DMX signal.
2. Check microphone to see if it is good by tapping the microphone
E. One of the channels is not working well
1. The stepper motor might be damaged or the cable connected to the PCB is broken.
2. The motor’s drive IC on the PCB might be out of condition
