5. 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 fan.
1. Check the connection of power and main fuse.
2. Measure the main 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, cables to see if
connected 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 connected to the PCB is
broken.
2. The motor’s drive IC on the PCB might be out of condition.
SYMPTOM
SOLUTION
FIXED AUTO-SHUT
OFF

have shut itself off due to high heat. This is to
protect the fixture from overheating.
No Light Output Check to ensure fixture is
operating under
NO LIGHT OUTPUT
Check to ensure fixture is operating under correct
mode, IE sound active/auto/DMX/Etc., if applicable.
CHASE SPEED
TOO FAST/SLOW
Check to ensure proper setup of speed adjustment.
NO POWER
Check fuse, AC cord and circuit for malfunction.
BLOWN FUSE
Check AC cord and circuit for damage, verify that
moving
parts are not restricted and that unit’s ventilation is
not obstructed
SLOW MOVEMENT
Check that speed channels are set appropriately.
FIXTURE NOT
RESPONDING/
RESPONDING
Make sure all connectors are seated properly and
