Elevator Light Curtain SSGM-154TC-P033 – Nanjing Zhuye Elevatorparts
The elevator light curtain is a vital safety component for elevator door systems, acting as an invisible protective barrier to prevent pinch injuries during door closing. It operates by forming a dense infrared light grid between the door panels; when any light beam is blocked by an obstacle, the system immediately sends a signal to the elevator controller to stop or reverse the doors, ensuring the safety of passengers and goods. The Elevator Light Curtain SSGM-154TC-P033 launched by Nanjing Zhuye Elevatorparts is a high-performance safety device tailored for mainstream elevator systems, widely compatible with renowned brands such as Schindler, OTIS, and KONE. Suitable for both passenger and freight elevators, this light curtain adopts advanced infrared sensing technology and precision electronic components, which can detect obstacles as small as 40mm in any position of the detection area, fully meeting the requirements of international elevator safety standards (EN 81-20, GB 7588). It has become a trusted choice for global elevator maintenance teams and manufacturers due to its high detection accuracy, fast response speed, and strong anti-interference ability.
Nanjing Zhuye Elevatorparts adheres to the “quality first, safety-oriented” principle, implementing strict quality control throughout the production process of the SSGM-154TC-P033 elevator light curtain. Each unit undergoes rigorous testing, including detection range verification, response time assessment, durability testing, and anti-interference performance inspection. Equipped with high-sensitivity infrared transmitting and receiving tubes and specialized filter technology, this light curtain can maintain stable operation even in harsh environments such as strong light, dust, and high humidity. The fully sealed metal shell with IP65 protection rating effectively prevents dust and water vapor from entering internal components, while the operating temperature range of -10℃ to 60℃ adapts to various elevator shaft environments. The SSGM-154TC-P033 also features a built-in self-diagnosis function, which can promptly detect faults such as wiring disconnections and send alarm signals to facilitate quick maintenance and troubleshooting.
Usage Guide for Elevator Light Curtain SSGM-154TC-P033
Correct installation, wiring, and debugging of the SSGM-154TC-P033 elevator light curtain are crucial to ensuring the safety of the elevator door system. Nanjing Zhuye Elevatorparts strongly recommends that only certified elevator maintenance technicians perform these operations—improper alignment, loose wiring, or incorrect parameter settings may cause light curtain failure, leading to potential pinch hazards or even safety accidents. It should be noted that improper use (such as pushing electric vehicles into the elevator) is a common cause of light curtain damage, which may result in frequent elevator faults and affect operational safety. Before operation, please carefully read the product manual provided by Nanjing Zhuye Elevatorparts and confirm the model matches the elevator door system parameters (such as door width and interface type).
1. Pre-Installation Preparation
First, confirm that the SSGM-154TC-P033 light curtain is compatible with the elevator’s door width, installation height, and electrical interface. Consult Nanjing Zhuye Elevatorparts’ technical team immediately if there is any doubt about compatibility. Then, strictly follow the safety regulations for elevator maintenance: cut off the elevator’s main power supply and door system power supply, lock the switch, and place a “Maintenance in Progress” warning sign at the elevator entrance and machine room. Fix the elevator car at a flat floor position and use a door stopper to block the door to prevent accidental closing. Prepare professional tools including a screwdriver, wrench, level ruler, multimeter, and anti-static gloves. Clean the installation area (car door and landing door frames) to remove dust, debris, and oil stains—dirty environments are one of the main causes of elevator component failures, so ensuring the mounting surface is flat and clean is essential.
2. Installation, Wiring & Debugging
Install the transmitting and receiving ends of the SSGM-154TC-P033 light curtain on the car door and landing door frames respectively, ensuring accurate alignment (the deviation should be less than 5mm) and the light beam grid is parallel to the door panel. Fix them firmly with screws according to Nanjing Zhuye’s torque specifications to avoid displacement due to door vibration during operation. Perform wiring strictly according to the wiring diagram provided by Nanjing Zhuye Elevatorparts: Connect the power cord and signal lines to the corresponding terminals of the elevator door controller. Ensure the shielding layer of the signal line is reliably grounded at the controller end to avoid electromagnetic interference, and keep the signal line at least 30mm away from the power line to prevent signal distortion. After wiring, restore the terminal cover before powering on as required by electrical safety regulations. For debugging: First, perform no-load power-on inspection to confirm the light curtain’s indicator light is normal (green light for normal operation, red light for fault). Use a thin object (such as a wooden stick) to block the light beam in different positions of the door area—the elevator door should stop closing or reverse immediately. Test the self-diagnosis function by disconnecting one of the signal lines; the controller should report a fault alarm promptly. Finally, run the elevator through multiple door opening and closing cycles to ensure the light curtain and door system work synchronously and stably.
3. Daily Use & Maintenance
According to the “Elevator Maintenance Rules” (TSG T5002-2017) and Nanjing Zhuye’s recommendations, the SSGM-154TC-P033 light curtain should be inspected every 15 days and undergo professional comprehensive testing annually. Daily cleaning is a key part of maintenance—power off before inspection, clean the surface of the light curtain’s transmitting and receiving ends with a dry cloth or lens cleaning paper to remove dust, fingerprints, and oil stains (avoid using water or chemical cleaners, as they may damage the optical components). Check the fixing screws quarterly and re-tighten them if loose to prevent misalignment. Inspect the signal line for wear, aging, or loose connections—replace damaged lines immediately and ensure the shielding layer is intact. Regularly test the light curtain’s function by blocking the light beam; if the door fails to stop or reverse, or the controller reports frequent light curtain faults, prioritize checking for issues such as misalignment, dirty lenses, or signal interference. If the light curtain fails to work normally, contact Nanjing Zhuye’s after-sales team for troubleshooting in a timely manner to avoid safety risks.
Replacement Cycle of Elevator Light Curtain SSGM-154TC-P033
The replacement cycle of the SSGM-154TC-P033 elevator light curtain is determined by operating frequency, working environment, and component aging. Under normal conditions (elevator daily operation 12-24 hours, door opening and closing ≥500 times/day, dry and clean environment), Nanjing Zhuye Elevatorparts recommends a replacement cycle of 4-6 years. This cycle is based on long-term field operation data and component reliability tests, fully considering the wear of infrared components, attenuation of signal transmission performance, and aging of the shell and wires.
For elevators in high-traffic areas (e.g., large shopping malls, airports with door opening and closing ≥1000 times/day) or harsh environments (high humidity, heavy dust, strong light interference, or frequent vibration), the replacement cycle should be shortened to 2-4 years. High-frequency operation accelerates the aging of infrared tubes and mechanical components, while harsh environments easily cause contamination of lenses and corrosion of wiring. For low-usage elevators (e.g., villa elevators, small office buildings with daily operation time <8 hours) in stable environments, the cycle can be extended to 6-8 years, but annual professional testing by Nanjing Zhuye’s technicians is required to confirm that the light curtain’s detection accuracy, response speed, and anti-interference ability meet safety standards.
Replace the SSGM-154TC-P033 light curtain immediately if any of the following issues occur, regardless of its service life: Frequent false alarms or failure to detect obstacles, leading to potential pinch hazards; severe damage to the shell (such as cracks or deformation) that affects sealing performance; internal components aging or damage resulting in unstable signal output; the light curtain fails to pass the annual professional safety test; frequent faults that cannot be resolved by maintenance (e.g., continuous self-diagnosis alarms, unresponsive to obstacle blocking). Timely replacement is critical to avoiding elevator operation safety accidents and protecting the lives and property of passengers, as damaged light curtains are one of the main causes of elevator failures.
