General Troubleshooting
SYMPTOM
POSSIBLE CAUSE(S)
POSSIBLE ACTION(S)
Breaker/Fuse keeps
blowing
Excessive circuit load
Check total load placed on the electrical
circuit.
Short circuit along the power wires
Check for a short in the electrical wiring
(internal and/or external).
Device does not power
up
No power
Check for power on Mains.
Loose power cord Check power cord
Fixture is not responding
to DMX
Wrong DMX addressing
Check Control Panel and unit addressing
Damaged DMX cables
Check DMX cables
Wrong polarity settings on the controller
Check polarity switch settings on the
controller
Loose DMX cables
Check cable connections
Faulty DMX interface
Replace DMX input
Faulty Main PCB
Replace Main PCB
Loss of signal
Non DMX cables
Use only DMX compatible cables
Bouncing signals
Install terminator as suggested.
Long cable / Low level signal
Install amplifier right after fixture with strong
signal.
Too many fixtures
Install an optically coupled DMX splitter after
unit #32.
Interference from AC wires
Keep DMX cables separated from power
cables or black lights.

General Maintenance
To maintain optimum performance and minimize wear, fixtures should be cleaned frequently. Usage and
environment are contributing factors in determining frequency. As a general rule, fixtures should be cleaned at
least twice a month. Dust build-up reduces light output performance and can cause overheating. This can lead
to reduced lamp life and increased mechanical wear. Be sure to power off fixture before conducting
maintenance.
· Unplug fixture from power.
· Use a vacuum or air compressor and a soft brush to remove dust collected on external vents.
· Clean all glass when the fixture is cold with a mild solution of glass cleaner or Isopropyl Alcohol and a
soft lint free cotton cloth or lens tissue.
· Apply solution to the cloth or tissue and drag dirt and grime to the outside of the lens.
· Gently polish optical surfaces until they are free of haze and lint.
The cleaning of 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 surroundings can cause greater accumulation of dirt on the unit’s optics. Clean with soft cloth using normal
glass cleaning fluid. Clean the external optics at least every 20 days. Clean the fixture at least every 30/60
days.
Always dry the parts carefully after cleaning them.
Never spin a fan using compressed air.
