• 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).

power up
• No power
• Check for power on Mains.
•
Loose power cord
•
Check power cord
Product 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 product
with strong signal.
• Too many products
• 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, products should be cleaned
frequently. Usage and environment are contributing factors in determining frequency.
As a general rule, products 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 product before
conducting maintenance.
• Unplug product from power.
• Use a vacuum or air compressor and a soft brush to remove dust collected
on external vents.
• Clean all lenses when the product is cool 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
product 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 product at
least every 30/60 days.
