Rain Vortex at Singapore Changi Airport: Light and Shadow Rhythm Where Nature Coexists with Technology

Troubleshoot in 4 steps:

1. Power Supply: Confirm the input voltage matches AC 200V~240V/50~60Hz; check if the power cable is securely connected and the switch is on.

2. Cooling Period: Ensure the fixture has cooled for 20 minutes after previous use (mandatory cooling to prevent overheat damage).

3. DMX Signal: If in DMX mode, verify the controller is sending "Shutter On" (CH6: 252-255) and "Dimming" (CH7: 100-255) signals.

4. Internal Wiring: If above checks pass, contact after-sales to inspect internal connections (e.g., lamp holder, driver board) for loose or burned components.

Resolve with these checks:

1. DMX Address & Channels: Ensure the fixture’s starting address is correct (e.g., 34CH fixture 1: A001, fixture 2: A035) and the controller’s channel count ≥ total fixture channels.

2. Signal Wiring: Use shielded twisted-pair DMX cables (≤150m); install a 120Ω terminal resistor between pins 2-3 of the last fixture’s XLR connector.

3. Signal Amplification: For cable lengths >150m, add a DMX signal amplifier to avoid signal loss; separate DMX cables from high-voltage power cables (≥1m apart) to prevent interference.

Standard configurations: approx. 4–8 weeks; custom projects depend on scale and logistics. Expedited options and rental alternatives available.

Separate purchase of accessories is supported. Common accessories (power cords, signal cables, standard lamp beads) are in stock and will be shipped within 1-3 days after ordering. Special accessories (e.g., hydraulic pumps for elevating lights, XY-axis motors for moving head lights) need to be reserved 3-5 days in advance. The after-sales team can provide accessory installation guidance (e.g., sending installation videos).
