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.
2. Measure the mains voltage on the main connector.
3. Check the power on LED.
B. Not responding to DMX controller
1. Check DMX connectors and cables to see if link properly.
2. 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. 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.
6. Fixture Cleaning
The cleaning must be carried out periodically to optimize light output. Cleaning frequency depends
on the environment in which the fixture operates: damp, smoky or particularly dirty surrounding
can cause greater accumulation of dirt on the unit's optics.
Clean with soft cloth using normal glass cleaning fluid.
Always dry the parts carefully.
Clean the external optics at least every 20 days. Clean the internal optics at least every 30 days.
