9. 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 connect power and main fuse.
2. Measure the mains voltage on the main connector.
3. Check the power on LED to see if it can be light up or not.
B. Not responding to DMX controller
1. DMX LED should be on. If not, check DMX connectors, ca-
bles to see if they are linked 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 to see if the DMX cables run near or run alongside
high voltage cables that may cause damage or interference
to DMX interface circuit.

nected to the PCB is broken.
2. The motor's drive IC on the PCB might be out of condition.

ther too high or too low.

ment of fan is needed on the head.
