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

Encoder closed-loop control, emergency stop circuits, software/hardware limit switches, load monitoring, and collision-avoidance zones. A comprehensive pre-performance checklist is provided.

For prefecture-level cities and above, an "exclusive wholesale cooperation" policy is implemented: If there is already a cooperative wholesaler in a region (with an annual purchase amount of ≥ 300,000 RMB), no second wholesaler of the same type will be developed. For county-level regions, 2-3 wholesalers can be developed based on market demand, but clear sales scopes must be divided (e.g., by town) to avoid vicious competition.

MOQ for wholesale: ≥ 10 units for a single model of conventional lights, and ≥ 5 units for a single model of elevating lights/moving head lights. Tiered pricing is supported: Taking conventional PAR lights as an example, a 5% discount is offered for 10-50 units, a 10% discount for 51-100 units, and a 15% discount for over 100 units. Specific quotations can be negotiated with the account manager based on the cooperation scale (e.g., annual purchase volume).

Address the issue as follows:

1. Mechanical Check: Open the fixture (after power-off) to inspect if the X/Y axis belts are loose or broken; re-tighten or replace belts if needed.

2. Optical Coupling Calibration: Enter "Settings → Motor Calibration → X/Y Axis" to adjust the offset (-128~+127) or enable "Optical Coupling" (auto-corrects step loss).

3. Reset & Restart: Press "Menu → Reset → XY Reset" to reposition the axes; if no response, check the X/Y axis photoelectric switches (replace if "X/Y Hall Error" appears in the error menu).
