8. 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.
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. Check DMX connectors, cables to see if they are linked 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 to see 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.
9. Fixture Cleaning
It is absolutely essential that the fixture is kept clean to ensure the maximum light-output and allow
the fixture to function reliably throughout its life. The fixture must be cleaned regularly to avoid
dust, dirt and smoke-fluid residues building up on or within the fixture. The cleaning frequency
depends on the application environment. Clean the fixture immediately if the dust enters it to avoid
damage to the optical lens due to excessive dust.
A soft lint-free cloth moistened with any good glass cleaning fluid is recommended, under no
circumstances should solvents be used.
Always dry the parts carefully.
Clean the external optical lens at least every 20 days and the internal optical lens every 30 days.
