5. Troubleshooting
Following are a few common problems that may occur during operation. Here are some
suggestions for easy troubleshooting:
A. If the unit does not work- no light output or fan is not working
1. Check the main power connection and the fuse.
2. Measure the mains voltage on the main power 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.
D. No response to the sound
1. Check the unit that is not receiving DMX signal.
2. Check the unit that is not set to display mode.
3. 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.
6. Fixture Cleaning
The cleaning of internal and external optical lenses and/or mirrors 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.
y
Clean with soft cloth using normal glass cleaning fluid.
y
Always dry the parts carefully.
y
Clean the external optics at least every 20 days. Clean the internal optics at least every
30/60 days.
