4. Trouble shooting
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 and main fuse.
2. Measure the mains voltage on the main connector.
3. Check the power on LED.
B. Not responding to DMX controller
1. DMX LED should be on. If not, check DMX connectors, ca-
bles 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. One of the channels is not working well
1. The stepper motor might be damaged or the cable con-
nected to the PCB is broken.
2. The motor's drive IC on the PCB might be out of condition.
5. 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 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 30/60 days.
