Elevator Light Curtain DAA24591C5: Door Safety Shield from Nanjing Zhuye Elevatorparts
Elevator Light Curtain DAA24591C5 is a critical safety protection component designed for elevator door systems, creating an invisible infrared light grid between the elevator car door and landing door to prevent pinch injuries. As the “safety barrier” for elevator door operation, it emits multiple infrared beams through the transmitting end; once an object or person blocks any beam during door closing, the light curtain immediately sends a signal to the elevator control system, forcing the doors to reverse and reopen—directly avoiding pinch accidents and ensuring passenger safety. Exclusively supplied by Nanjing Zhuye Elevatorparts (a professional and trusted distributor of high-quality elevator safety components), theElevator Light Curtain DAA24591C5 fully complies with international elevator safety standards (EN 81-20, GB 7588) and infrared safety device regulations (IEC 61496). With high detection accuracy, strong anti-interference capability, and wide compatibility with mainstream elevator models, this light curtain is widely applied in residential, commercial, high-speed, and industrial elevators worldwide.
Nanjing Zhuye Elevatorparts adheres to the core philosophy of “precision detection, all-round protection” and implements strict quality control over the Elevator Light Curtain DAA24591C5. Each unit undergoes multi-stage pre-delivery inspections, including detection range verification, response speed testing, anti-interference performance trials, and environmental adaptability tests. The product adopts advanced infrared sensing technology and rugged structural design: it features 48 pairs of infrared beams with a detection height of 2000mm, covering the entire door area without blind spots; the response time is ≤ 20ms, ensuring instant door reversal even for fast-closing elevator doors; the IP54 dustproof and waterproof rating adapts to the humid, dusty environment in elevator doorways; the reinforced aluminum alloy housing effectively resists collision and wear during long-term use. Its standardized mounting interfaces and signal protocols are perfectly matched to elevator door control systems, enabling quick and seamless installation without complex modifications.
Step-by-Step Usage Guide for Elevator Light Curtain DAA24591C5
To ensure the reliable operation of the elevator door safety system and give full play to the protective role of the DAA24591C5 light curtain, follow the professional guidelines provided by Nanjing Zhuye Elevatorparts for installation, debugging, and maintenance:
1. Professional Installation & Debugging
Installation must be performed by certified elevator technicians familiar with elevator door systems. Prior to installation, confirm the compatibility of the DAA24591C5 with the target elevator’s door type and control system using the detailed compatibility manual provided by Nanjing Zhuye Elevatorparts. The steps are as follows:
-
Safety Preparation: Cut off the elevator’s main power supply and lock the power switch. Fix the elevator car to a safe position to prevent accidental movement. Clean the mounting positions on the inner sides of the car door and landing door (where the light curtain transmitting and receiving ends are installed) to remove dust, oil stains, and debris that may affect installation accuracy and light transmission.
-
Light Curtain Installation: Install the transmitting end and receiving end of the DAA24591C5 light curtain on the dedicated mounting brackets (provided by Nanjing Zhuye) on both sides of the door. Ensure the two ends are aligned horizontally (alignment deviation ≤ 2mm) and vertically (vertical deviation ≤ 1mm), and the light grid is parallel to the door panel. Tighten the mounting bolts to avoid loosening due to door vibration. Connect the signal cable of the light curtain to the elevator door control system’s corresponding interface, ensuring correct wiring and reliable insulation.
-
Post-Installation Debugging: Restore the power supply and switch the elevator to inspection mode. Activate the door closing function and use a test rod (provided by Nanjing Zhuye) to block different positions of the light grid—confirm that the doors immediately reverse and reopen each time, with no false alarms or missed detections. Adjust the sensitivity of the light curtain (via the adjustment button on the housing) if necessary. Test the door closing function 10–15 times continuously to verify the light curtain’s stable performance.
2. Daily Operation & Routine Inspection
Regular inspections are crucial to early detection of light curtain faults and ensuring door safety. Maintenance personnel should incorporate the following checks into their daily patrols:
-
Daily Visual Inspection: Check the external condition of the DAA24591C5 light curtain. Ensure the transmitting and receiving ends are intact (no cracks or damage to the lens), the housing is free of deformation or rust, and the signal cable is intact without aging or wear. Clean the lens surface with a soft, dry cloth to remove dust, fingerprints, or stains (avoid using corrosive cleaners that may scratch the lens).
-
Weekly Functional Test: Conduct a comprehensive functional test—block the light grid with different objects (e.g., hand, bag, test rod) during door closing to confirm the doors reverse normally. Check the light curtain’s status indicator lights (normal operation: green light; fault: red light or flashing) to ensure no abnormal signals. Test the door closing force (assisted by professional equipment) to ensure it meets safety standards when the light curtain is triggered.
-
Monthly System Check: Recheck the alignment of the light curtain’s transmitting and receiving ends (deviation may occur due to long-term vibration). Inspect the wiring terminals for looseness, oxidation, or burning marks—retighten or clean if necessary. Verify the light curtain’s anti-interference performance by testing door operation near other electrical equipment (e.g., frequency converters).
3. Regular Maintenance Schedule
Systematic maintenance can effectively extend the service life of the DAA24591C5 elevator light curtain. Follow Nanjing Zhuye Elevatorparts’ recommended maintenance plan:
-
Quarterly Maintenance: Disconnect the power supply and remove the light curtain from the mounting brackets (if necessary). Thoroughly clean the lens and housing with a professional cleaner. Inspect the internal circuit board (via the inspection window) for dust accumulation or component damage. Reinstall the light curtain and recheck the alignment and functional performance.
-
Semi-Annual Performance Test: Conduct a professional performance test, including detection range, response time, and anti-interference capability. Simulate extreme operating conditions (e.g., low-temperature, high-humidity environments, strong light interference) to verify the light curtain’s stable operation. For elevators in high-traffic areas (e.g., shopping malls, airports), increase the test frequency to once every 3 months.
-
Annual Professional Overhaul: Arrange a professional inspection with Nanjing Zhuye Elevatorparts’ certified technical team. Calibrate the light curtain’s detection accuracy and signal transmission to meet the original factory standards. Replace aging signal cables or connectors with genuine parts. Evaluate the overall performance of the light curtain and adjust the maintenance plan according to the actual operation status.
Recommended Replacement Cycle for Elevator Light Curtain DAA24591C5
As a core safety component bearing long-term infrared emission, frequent signal transmission, and environmental erosion (humidity, dust, vibration, strong light), the DAA24591C5 elevator light curtain has a specified service life. Timely replacement is critical to avoiding faults such as reduced detection accuracy, delayed response, false alarms, or complete failure—issues that may lead to elevator door pinch accidents, endangering passenger safety.
1. Standard Replacement Cycle
Under normal operating conditions (elevator daily operation time 12–24 hours, daily door opening/closing cycles ≥ 1500, environment temperature -10–60℃, humidity 10%–95%), the recommended replacement cycle for the Elevator Light Curtain DAA24591C5 is 4–5 years. This cycle is determined based on Nanjing Zhuye Elevatorparts’ long-term field data, light curtain component aging tests, and global user feedback.
2. Adjustments for Special Scenarios
-
Harsh Environments: For elevators in high-humidity coastal areas (salt spray corrosion), high-dust construction sites, or locations with strong light interference (e.g., direct sunlight on doorways) or frequent voltage fluctuations, the replacement cycle should be shortened to 2–3 years. Harsh conditions accelerate lens aging, circuit board corrosion, and component damage, significantly reducing the light curtain’s reliability.
-
Low-Frequency Use Scenarios: For elevators with low usage frequency (e.g., villa elevators, small office buildings with daily operation time < 8 hours) and stable environments (no strong light or dust interference), the replacement cycle can be extended to 5–6 years—only if Nanjing Zhuye’s professional inspection confirms the light curtain’s detection accuracy, response speed, and anti-interference performance are intact (consistent with original factory standards).
3. Immediate Replacement Conditions
Replace the Elevator Light Curtain DAA24591C5 immediately if any of the following issues occur, regardless of service life:
-
The light curtain fails to detect obstacles (doors do not reverse when blocked) or has frequent false alarms (doors reverse without obstruction), and the fault persists after debugging and maintenance.
-
The lens is severely scratched, cracked, or fogged, affecting light transmission and detection accuracy.
-
The light curtain’s status indicator light shows a fault signal (red light on or flashing) and cannot be restored to normal after troubleshooting.
-
The light curtain’s response time exceeds 50ms (tested by professional equipment), failing to meet the elevator’s safety operation requirements for door reversal.
