Usage Guide for Elevator LOP Display Board A3N53390
Correct installation, debugging, and operation of the A3N53390 LOP display board are vital to ensuring smooth human-machine interaction and elevator operational safety. Nanjing Zhuye Elevatorparts strongly recommends that only certified elevator electrical technicians perform installation and maintenance, while passengers should operate the board in accordance with standard procedures to avoid damage.
1. Pre-Installation Preparation
First, confirm that the A3N53390 display board matches the elevator model (check parameters such as voltage, interface type, and installation dimensions). Consult Nanjing Zhuye Elevatorparts’ technical team immediately if there is any doubt about compatibility. Then, cut off the elevator’s main power supply and control cabinet power supply, lock the switch, and place a “Maintenance in Progress” warning sign at the elevator entrance. Remove the old display board from the cab or landing hall panel, and take photos to record the wiring direction and terminal connections for future reference. Finally, prepare professional tools including a screwdriver, wire stripper, multimeter, and anti-static gloves, and clean the installation area to remove dust, debris, and oil stains.
2. Installation & Debugging
Take the new A3N53390 display board from Nanjing Zhuye Elevatorparts, align it with the installation slot, and fix it firmly with screws (avoid over-tightening to prevent damaging the board). Connect the wires to the corresponding terminals strictly according to the recorded photos and Nanjing Zhuye’s wiring manual, ensuring firm connections and correct polarity (reverse connection may burn the board). After wiring, use a multimeter to test the input voltage to confirm it matches the board’s rated voltage. Restore the power supply and enter the elevator’s debugging mode: check if the display board correctly shows the floor number, running direction, and door opening/closing status; test the touch buttons to ensure they can accurately transmit operation instructions. Adjust the display brightness if necessary to ensure optimal visibility for passengers.
3. Daily Use & Maintenance
For passengers: Operate the buttons gently and avoid using sharp objects to touch the display screen to prevent scratches. For maintenance personnel: Inspect the display board during monthly elevator patrols—check if the display is clear (no flicker, ghosting, or dead pixels), the buttons are responsive, and the wiring terminals are tight. Clean the display screen and button surface with a soft dry cloth regularly; do not use water or chemical cleaners. Every 3 months, recheck the board’s fixed screws and wiring connections, tightening any loose parts. If fault codes appear on the display, refer to Nanjing Zhuye’s technical manual for troubleshooting, or contact the after-sales team for professional support.
Replacement Cycle of Elevator LOP Display Board A3N53390
The replacement cycle of the A3N53390 LOP display board is closely related to operating frequency and working environment. Under normal conditions (elevator daily operation 12-24 hours, dry and clean environment, no frequent impact), Nanjing Zhuye Elevatorparts recommends a replacement cycle of 3-5 years. This cycle is determined based on long-term field operation data and component aging tests, fully considering the aging of the display screen, wear of buttons, and attenuation of internal electronic components.
For elevators in high-traffic areas (e.g., large shopping malls, airports with daily passenger flow exceeding 10,000 people) or harsh environments (high humidity, heavy dust, frequent vibration, or direct sunlight), the replacement cycle should be shortened to 2-3 years. High-frequency use accelerates button wear and screen aging, while harsh environments cause component corrosion and reduce display clarity. 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 5-6 years, but only after inspection and confirmation by Nanjing Zhuye’s technicians that all functions of the display board meet safety standards.
Replace the A3N53390 display board immediately if any of the following issues occur, regardless of its service life: The display screen is severely scratched, cracked, or has extensive dead pixels (affecting information reading); buttons are unresponsive or stuck, causing operation failures; the board frequently malfunctions (e.g., wrong floor display, flicker, or black screen) and cannot be repaired; internal components are burned (accompanied by burning smell or smoke); the board’s shell is severely deformed or corroded, losing protective performance.
