7. 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, cables 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 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.
8. 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 30/60 days.
