The lamp does not light up. What should I check?
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.
The fixture does not respond to the DMX controller. How to fix it?
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.
After-Sales Support
Can technical training be provided? For example, teaching customers how to debug DMX consoles and set light addresses.
Free technical training is supported:
▪ Online training: Operation video tutorials and live teaching (e.g., a "DMX Light Control Practical Course" once a month) are provided.
▪ Offline training: For wholesale customers (with a single purchase of ≥ 100 units), technicians can be arranged for on-site training (1-2 days, including console debugging, address setting, and fault troubleshooting).
▪ Customized training: For large-scale projects (e.g., stadium lighting projects), on-site technical guidance can be provided (charged based on the project cycle, specific details to be negotiated).
Logistics Services
What logistics method is used by default for products? What is the delivery time for different regions in China?
Dedicated line logistics (e.g., Anneng, Best Express) is used by default. Express delivery (e.g., SF Express, JD Express) or full-truck transportation can also be arranged according to customer needs. Delivery time:
▪ East China/South China/Central China: 3-5 days.
▪ North China/Southwest China: 5-7 days.
▪ Northeast China/Northwest China: 7-10 days.
▪ Remote areas (e.g., Xinjiang, Tibet): 10-15 days, with an additional remote area freight charge (calculated by weight, specific details to be confirmed with the logistics department).
