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.
D. The lamp is cutting out intermittently
1. The lamp is not working well. Check the mains voltage either too high or too low.
2. Internal temperature may be too high. Check if replacement of fan is needed on the head.
9. 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.
Clean with soft cloth and use normal glass to clean liquid.
Always dry the parts carefully.
Clean the external optics at least every 20 days. Clean the internal optics at least every 30 days.
