User Manual for Beamz Cobra 720 Moving Head

Quick guide from the manual

The Beamz Cobra 720 is a moving head lighting fixture designed for indoor use. Before operation, ensure the unit is free from transport damage, verify that the mains voltage matches the unit's specifications, and ensure adequate ventilation (at least 50 cm of free space). Always use a safety cable when mounting the unit above 100 cm.

Installation and Rigging

The unit can be set up on a stable surface or mounted upside down on a truss. To mount on a truss:

• Use certified clamps with the correct load capacity.
• Attach the omega brackets to the base plate using the quick-lock fasteners.
• Turn the fasteners clockwise until they lock.
• Always secure the unit with a safety cable attached to the designated fixation points, never to the transport handles.

Power Supply

Check the label on the back of the unit for the required voltage. The unit must be connected directly to the mains; do not use a dimmer pack. Multiple units can be linked using the power connector input and output. Connect a maximum of four units in a row when using 230V/16A. Use an approved three-core cable with a cross-section of at least 1.5 mm².

DMX512 Control

To control the unit via DMX:

• Connect the DMX output of your controller to the DMX input of the first unit.
• Daisy-chain subsequent units by connecting the output of one unit to the input of the next.
• At the last unit in the chain, you must terminate the DMX line. Solder a 120 Ohm resistor between signal (-) and signal (+) on an XLR connector and plug it into the DMX output of the last unit.

Maintenance and Cleaning

Regular maintenance is required to ensure optimal performance and longevity. Inspect the unit for dust buildup, especially in dusty or smoky environments. To clean:

• Disconnect from power and allow the unit to cool completely.
• Use a vacuum or low-pressure compressed air to remove dust from surfaces and vents. Do not let fan blades spin while cleaning.
• Clean glass components with a soft, lint-free cloth and a weak detergent solution.
• If the fuse is defective, replace it with one of the same type and value. Open the fuse holder on the rear panel with a screwdriver, remove the old fuse, install the new one, and replace the holder.

Troubleshooting

If the unit does not respond, check the power supply and connections. If it does not respond to the DMX controller, verify the DMX line, ensure the controller is connected, and check the DMX address settings. If the light output is intermittent, the unit may be overheating; ensure proper airflow and clean the unit if necessary.
