The elevator sets the date and time for braking torque self-test. When the elevator is in no-load idle state (the server view status is "IDL U00D00 A /"), the elevator enters the Self-BTI detection mode, and the inverter automatically simulates the car 125% and 150% load condition, and detect the brake torque. Only if both conditions are qualified, the elevator can resume normal operation. If insufficient torque is detected, the elevator will be in a locked state and cannot be used normally. The inverter will report "426" BTI NG Lock" fault, the inverter is in Shut down. At this time, switch ERO more than 3 times before the shutdown fault can be cleared. Only ERO or maintenance operation can be performed. The brake needs to be checked. After the manual torque detection is successful, the elevator can return to normal use.

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.
