CANNY Escalator Fault Display Board XS-B V3.1 MLJD

CANNY Escalator Fault Display Board XS-B V3.1 MLJD is used in CANNY escalator safety circuit fault display and inspection applications.

This board is normally installed in the escalator control or inspection system to help display safety circuit fault information during maintenance and troubleshooting. In the escalator spare parts market, it may also be searched as:

• CANNY Escalator Fault Display Board
• CANNY Escalator Safety Fault Display Board
• XS-B Fault Display Board
• XS-B V3.1 Escalator Display Board
• XS-B V2.2 Fault Display Board
• MLJD Escalator Fault Board
• Escalator Safety Circuit Fault Display Panel

The main model references for this page are:

• XS-B
• XS-B V3.1
• XS-B V2.2
• MLJD
• MLJD-2014-9-10

Because different versions may appear in the market, the old board label, power supply requirement, display type, and terminal wiring should be confirmed before ordering.

Safety Circuit Fault Display Application

XS-B V3.1 is not a normal decorative display board. It is more closely related to escalator safety circuit checking, fault indication, and maintenance diagnosis.

When the escalator safety circuit has an abnormal input, the fault display board helps technicians identify the related fault point faster. This can reduce troubleshooting time and make site maintenance more efficient.

Maintenance teams may check this board when there are problems such as:

• escalator safety circuit fault
• abnormal fault code display
• fault memory issue
• inspection display not responding
• safety switch signal abnormality
• terminal wiring fault
• damaged display or PCB components

These symptoms may also be caused by safety switches, wiring terminals, sensors, control cabinet power supply, or related escalator monitoring circuits. The complete safety circuit should be checked before confirming the board fault.

Version and Voltage Confirmation

Before ordering CANNY Escalator Fault Display Board XS-B V3.1 MLJD, please confirm:

• Complete XS-B marking on the old board
• Whether the old board is V2.2 or V3.1
• MLJD or MLJD-2014-9-10 marking if visible
• AC110V or DC24V selection requirement
• Terminal block or digital tube version if applicable
• Front and back photos of the PCB
• Connector and terminal wiring photos
• Installation position inside the escalator control cabinet
• Existing fault display issue from the maintenance technician

Some market descriptions mention that the new version can be compatible with old CANNY models, but the actual replacement should still be confirmed by the old board version, wiring layout, and site voltage.

Practical Replacement Notes

Do not select XS-B V3.1 only by appearance.

Escalator fault display boards may look similar, but voltage selection, wiring terminal arrangement, fault display method, and system version may be different. If the wrong version is installed, the fault display may not work correctly or may not match the original escalator safety circuit.

Before installation, technicians should compare the old and new board carefully and check the safety circuit wiring, terminal condition, cabinet power supply, and related safety switch signals.

For overseas buyers, sending clear photos of the old XS-B V3.1 / MLJD board, terminal wiring, and control cabinet installation position is the safest way to reduce wrong supply.
