Elevator LOP Display Board with CAN Bus Communication Flame-Retardant Green PCB for Real-Time Floor Number Display

Elevator LOP Display Board A3N53645 A3J53644 | Hall Call Floor Position Direction Indicator PCB Lift Replacement Spare Parts

A3N53645 (Matching Code A3J53644) is the original hall landing outer call display PCB exclusively for CANNY SWEET elevators, also compatible with partial OTIS SWEET series control systems. It is installed on each floor landing panel as the human-machine interaction module, adopting digital tube dot-matrix display and CAN bus communication. The flame-retardant green PCB with integrated anti-interference circuit ensures stable signal transmission in complex hoistway electromagnetic environment.

Real-time Floor Number & Direction Display
Receives running data from elevator main control board via CAN bus, synchronously shows current stop floor and upward/downward running direction for passengers waiting at landing doors.
Hall Call Signal Transmission & Feedback
Collects up/down call button signals from each floor, uploads request commands to mainboard; feeds back call light on/off signal to remind passengers the elevator has received their call request.
Elevator Fault Status Prompt
Automatically display specific fault codes when the system triggers protection, such as overloading, door failure or safety circuit abnormality, assisting maintenance staff in rapid fault location.
Group Control Synchronized Linkage Display
Supports multi-elevator group control scheduling, synchronizes running information of multiple lifts on each floor landing display board to optimize passenger waiting efficiency.
Stable Safety Human-Machine Interaction
As essential landing signal module complying with elevator safety standards, it realizes transparent running information interaction between passengers and elevator control system, improving user experience and maintenance convenience.

Elevator Display - FAQ

Q1: What types of displays are used in elevator systems?
Elevator systems use LED indicators, LCD screens, including TFT LCD displays, and other display technologies to show floor numbers, travel direction, and operating status.

Q2: Are elevator displays with the same screen size interchangeable?
Not necessarily. Displays with the same dimensions may differ in supply voltage, communication protocols, connector configurations, and control requirements. Compatibility must be verified before replacement.

Q3: What causes an elevator floor display to show incorrect information?
Possible causes include communication errors, controller configuration problems, wiring faults, or display module failure. The actual cause should be identified before replacement.

Q4: Can an elevator display be upgraded without replacing the control system?
In some systems, the display can be upgraded separately if the replacement supports the existing controller, communication protocol, and electrical requirements.

Q5: What information is required to order a replacement elevator display?
Please provide the original part number, display type, screen dimensions, supply voltage, communication interface, connector details, controller model, and clear photos for accurate matching.
