Inspection mode GECB power-on inspection

Voltage check

Disconnect the main power supply in the distribution box, the car and shaft lighting power switches, and all air switches in the control cabinet, unplug the GECB and all plug-ins on the inverter, and then turn the operating mode knob on the emergency electric running box to EROR mode. Use the electricity meter to confirm that the voltage range of each phase in the distribution box should be 380V±5%, and turn on the main power switch of the distribution box.
Use an electric meter to confirm the initial side voltage range of the lighting power switch is 220V±5%, and close the switch.
Turn on the main power switch and observe whether the indicator light of the inverter is on.
Close CP1 and observe whether the phase sequence relay is normal.
Confirm that the initial side voltage of each air switch is normal according to the table below, then close the switch.

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.
