Communication Relay: Serving as the signal hub within the hoistway, it receives signals from hoistway sensors (such as leveling, limit switches, and safety switches), the car, and hall call buttons. It communicates bidirectionally with the main control board (such as LCECPU) via a serial bus (such as TTS/LCE bus) to achieve signal transmission.

Audio-Visual Alarm Drive: It has a built-in alarm drive circuit. When the elevator triggers a fault (such as a safety circuit disconnection, door zone abnormality, or overspeed), it receives instructions from the main control board to drive the buzzer to sound and the warning light to flash, providing an audible and visual alarm within the hoistway.

Status Feedback: The system provides real-time feedback on the operating status and alarm signals of the hoistway equipment to the main control system. Based on this feedback, the main control system determines whether the elevator meets operating conditions, ensuring safety.

Core Function: It establishes a signal link between the hoistway and the control cabinet, serving as a crucial communication node for elevator safety monitoring, fault alarms, and stable operation.

Elevator PCB Board - FAQ

Q1: How do I identify the correct replacement elevator PCB board?
To identify a replacement elevator PCB board, check the original part number, hardware revision, board markings, and elevator controller model. Clear photos of both sides of the PCB can help distinguish different versions.

Q2: Can elevator PCB boards with similar part numbers be interchangeable?
Not necessarily. Elevator PCB boards with similar part numbers may differ in hardware revisions, firmware, connector layouts, or communication protocols. Compatibility must be verified against the existing elevator system.

Q3: Does a replacement elevator PCB board require programming?
Some replacement PCB boards require firmware configuration, parameter settings, or system-specific programming. Others may already contain the required software. The correct procedure depends on the PCB model and its role in the elevator control system.

Q4: Can a faulty elevator PCB board be replaced without changing the complete control system?
In some cases, an individual PCB can be replaced if the replacement is compatible with the existing controller, firmware, wiring, and connected components. A qualified technician should confirm the fault before deciding on replacement.

Q5: What information should I provide when sourcing a replacement elevator PCB board?
Please provide the original PCB part number, hardware revision, elevator model, clear board photos, and required quantity. SULAB can help review these details and check available replacement options.
