Dedicated technical guidelines, troubleshooting directories, and maintenance protocols for commercial system integrators and field engineers.
Troubleshooting Directory
1. Fault: No output brightness / Lamp not turning on
Bulb & DMX Check: Check whether the bulb has reached its service life or is damaged. Ensure the DMX512 controller has sent the "switch on" instruction.
Hot Start Protection: If the bulb is not completely cooled, it will not ignite to protect itself. Allow the fixture to cool for more than 15 minutes before restarting.
Power Supply: Check the DC380V power supply output and connection cables. Replace if abnormal.
Temperature & Fans: Check the menu (Information â Fans speed). Fan speed should be over 5000RPM. If lower, the bulb will stop working. Check the temperature sensor near the bulb (Information â Fixture Temperatures).
2. Fault: The bulb is flashing on and off (working intermittently)
Cooling System Defense: If the bulb automatically turns on after a few minutes off, check the cooling system. If internal temperatures get too high, the thermostatic switch turns off the light for protection.
Obstruction Check: Check for dust, paper scraps, or foreign objects causing poor heat dissipation near the fans.
Data Fluctuations: Verify fan speeds in the menu. If a fan indicates 0 RPM, focus on possible open circuits or bad contacts in the yellow fan cable.
3. Fault: The light spot is off-center, dark, or uneven
Lifespan Check: Check if the bulb has reached the end of its service life and replace with the exact model.
Optical Cleaning: Clean any dust accumulation on the optical components.
Calibration (Left/Right): Finely adjust the alignment screw to change the bulb position.
Calibration (Up/Down): Navigate via menu: Menu â SERVICE â Calibration â STAT GOBO â Gobo, then adjust the spot accordingly.
4. Fault: Fixture reset is not working or screen is completely blank
Power Input: Ensure proper input power. Check the fuse on the input side of the switch power supply and verify input/output voltages.
Display Board: If the display remains black while power is confirmed, the display board may need replacement.
5. Fault: Fixture is out of control or moving unusually
Signal Verification: Check that the DMX address code is set correctly and the connection line (DMX connectors â X/Y drive board â display board) has no short circuits.
Power Protocol: Controlling multiple lights with a single main power switch can cause the machine to crash and burn out the drive board. Always follow the rule: "Control one light with one power switch."
Heat Dissipation: If moving unusually after hours of work, it is likely due to bad heat dissipation on the drive board. Clean the cooling fans and air vents immediately.
6. Fault: Mechanical components jam, jitter, or go out of sync
Mechanical Jams: Usually caused by deformed pattern/color plates, or loose screws on the rotating shaft.
Induction Distance: For GOBO, color wheel, or CMY modules out of step, check the induction distance between the small magnet and the sensor. The optimal distance is 1.0 - 2.0 mm. A larger distance easily causes misalignment.
7. Fault: X/Y Pan and Tilt are out of step or not positioning correctly
Encoder Cleaning: Clean the light coupling (encoder) with anhydrous alcohol if covered in dust.
Environmental Interference: If used outdoors, check for water droplets on the light coupling reading dial, which can cause reading inaccuracies.
Belt Tension: Check if the X/Y motor drive belt is aging, loose, or too tight.
Recalibration: Navigate to: Menu â SERVICE â Adjust â Pan or Tilt.
Maintenance Methods & Precautions
Recommended Cleaning Cycle
To ensure normal and stable operation, fixtures should be cleaned regularly. The standard cycle is generally one month.
If operating in highly dusty environments, or near smoke, bubble, or snow machines, the cleaning frequency must be shortened significantly.
Standard Cleaning Methods
Internal Dust: Use a vacuum cleaner, air gun (with moderate pressure), or gasbag to gently blow away surface dust, or use a soft brush.
Optical Lenses: Use odorless tissue paper or a cotton cloth soaked in ethanol (alcohol) to remove dust and odor residue. Use distilled water for a final wipe, then dry with a soft cotton cloth.
Coating Protection: The color coating on the color plate, GOBO plate, and optical lenses is extremely brittle and easily scratched. Never use destructive solvents for cleaning.
Important Mechanical Precautions
Lubrication: When clearing the focus, zoom, and other sliding parts, strictly use special high-and-low-temperature-resistant lubricating oil. Do not use heating dry or low-temperature condensate oil to prevent mechanical slide issues.
Rotating Parts: Lenses and other rotating parts must be inspected regularly to keep them clean and stable. Any obvious damage or looseness requires immediate reinforcement or replacement to prevent accidents during operations.
