Cedes Easygard 100DUD RX/TX-2000-17 Elevator Light Curtain

Elevator Light Curtain – FAQs

Q1: How does an elevator light curtain work?
An elevator light curtain uses multiple infrared beams to detect objects within the protected doorway area. When an obstruction is detected, it sends a signal to the door control system to initiate the appropriate door response.

Q2: Are elevator light curtains compatible with different door systems?
Not always. Compatibility depends on supply voltage, output signals, controller interfaces, mounting dimensions, detection coverage, and applicable safety requirements.

Q3: Why does an elevator door keep reopening when no obstacle is visible?
Possible causes include sensor contamination, misalignment, wiring faults, controller problems, or other door protection signals. Repeated reopening does not necessarily indicate a defective light curtain.

Q4: Can an elevator light curtain be replaced without changing the door controller?
In some systems, a compatible light curtain can be replaced separately. However, the electrical interface, output logic, detection coverage, and safety requirements must be verified.

Q5: What specifications should I provide when ordering a replacement elevator light curtain?
Please provide the original model, supply voltage, sensor dimensions, detection area, output type, connector photos, and door controller model.
