Elevator Light Curtain WECO-957ML51-DC24B | Compatible with KONE Elevators
The Elevator Light Curtain WECO-957ML51-DC24B is a high-precision infrared safety protection component exclusively designed and fully compatible with KONE elevators. Mounted on both sides of the elevator car door, this professional sensor module acts as the core anti-pinch safety device for KONE elevator door systems. It builds a full-coverage infrared protection grid across the door opening, accurately detecting passengers, goods and obstacles in real time to trigger instant door reversal and prevent clamping injuries. Common elevator door safety faults including unresponsive anti-clamp function, intermittent sensor failure, abnormal door cycling and recurring safety error codes are mainly caused by infrared probe aging, internal circuit attenuation, lens dust accumulation and long-term mechanical vibration. Manufactured in strict accordance with KONE’s original electrical protocols and mounting standards, the WECO-957ML51-DC24B light curtain serves as a standard OEM replacement part for daily maintenance, safety system troubleshooting and bulk spare parts inventory for global elevator service providers.
Featuring high-sensitivity infrared transceivers and stable DC24B dedicated drive circuits, the KONE Elevator Light Curtain WECO-957ML51-DC24B delivers outstanding detection accuracy and long-term operational stability. Optimized for the high-frequency cyclic door operation of KONE elevator systems, it effectively resists indoor light interference, dust pollution and mechanical shaking, maintaining consistent and sensitive signal induction without response delay or signal dropout. All electrical parameters, interface definitions and mounting dimensions strictly comply with KONE factory specifications, supporting direct plug-and-play installation without circuit modification or complex parameter calibration. Equipped with built-in overvoltage and short-circuit protection functions, this light curtain avoids circuit burnout and system disorder, perfectly adapting to long-duration continuous operation of mainstream KONE residential and commercial elevators.
Standard Installation & Professional Operation Guidelines
All disassembly and installation work for the WECO-957ML51-DC24B elevator light curtain must be performed by certified technicians specializing in KONE elevator maintenance. Before operation, completely cut off the elevator door control power and safety circuit power, lock the safety isolation switch, and place a prominent “Maintenance In Progress” warning sign on-site. Live-line operation and blind disassembly are strictly prohibited to prevent electric shock accidents, circuit short-circuits and failure of the elevator safety protection system.
Enter the elevator car top with standard insulated maintenance tools and locate the original light curtain fixed on the car door frames. Verify the model to confirm full compatibility with the KONE WECO-957ML51-DC24B standard. Disconnect all power lines and signal connectors in sequence with clear marking for accurate reinstallation. Remove the fixing fasteners and gently dismount the faulty or aging original device. Thoroughly clean the infrared probe lenses and mounting bases to eliminate dust and stains that may block infrared signals and cause detection failure.
Install the brand-new WECO-957ML51-DC24B light curtain at the standard mounting position and fasten all fixing parts securely to prevent displacement from long-term door vibration. Reconnect all wiring strictly following the marked sequence and double-check all terminals for firm connection and correct circuit logic. After installation, restore the power supply and conduct comprehensive functional tests, including full-range infrared detection, door anti-clamp linkage debugging and continuous operating tests, to ensure stable, sensitive and fault-free safety protection for KONE elevator door systems.
Scientific Replacement Cycle & Fault Replacement Standards
The service life of the WECO-957ML51-DC24B elevator light curtain varies with elevator operating frequency and environmental conditions. For conventional residential and low-frequency office KONE elevators, the recommended standard replacement cycle is 6 to 8 years.
For high-traffic scenarios such as shopping malls, hospitals and transportation hubs, or dusty and humid environments, the light curtain suffers from frequent vibration and environmental erosion. It is recommended to shorten the replacement cycle to 4 to 5 years to avoid sudden safety protection failure and potential elevator operational risks.
Immediate replacement of the WECO-957ML51-DC24B light curtain is required once abnormal symptoms occur, including insensitive anti-clamp response, frequent safety fault codes, intermittent signal loss and blurred probe lenses. Timely replacement eliminates hidden door safety hazards and maintains reliable protective performance for all KONE elevator systems.
