CANNY Elevator Car-Top Communication Board KLS-TCD-01A

CANNY Elevator Car-Top Communication Board KLS-TCD-01A is used in the car-top control and communication area of CANNY elevator systems.

This board is normally installed around the elevator car roof, where signals from the car, door system, inspection operation, and control cabinet may be connected through the car-top wiring system. In the elevator spare parts market, it may also be searched as:

• CANNY Elevator Car-Top Communication Board
• CANNY Elevator Car Top Board
• CANNY Car Roof Control Board
• CANNY Elevator Car Top Control Board
• CANNY Elevator Communication PCB
• KLS-TCD-01A Elevator PCB Board
• CANNY Elevator PCB Board

The main model reference for this page is:

• KLS-TCD-01A

Related reference:

• KLS-TCD-02A

KLS-TCD-02A may appear as a related car-top expansion board in some CANNY control system information. It should be treated as a related board reference, not as a direct replacement for KLS-TCD-01A without checking the original elevator system.

Car-Top Communication Application

KLS-TCD-01A is different from a cabin COP communication board.

A COP communication board is usually located inside or near the car operating panel. KLS-TCD-01A is more closely related to the car-top control area, where door operator signals, inspection operation wiring, cabin communication, and controller-side connections may meet.

This board may be checked when the elevator has issues such as:

• car-top communication abnormality
• inspection operation signal problem
• door-related signal interruption
• car roof wiring fault
• communication between car and controller not stable
• connector or terminal problem around the car-top box
• visible PCB damage on the car-top board

These symptoms should not be judged only by the board name. The car-top wiring harness, inspection box, door operator wiring, communication cable, power supply, and controller-side signal circuit should also be checked before confirming the PCB fault.

How to Confirm the Correct Board

Before ordering CANNY Elevator Car-Top Communication Board KLS-TCD-01A, please confirm:

• Complete KLS-TCD-01A marking on the old board
• Front and back photos of the PCB
• Connector quantity and connector direction
• Car-top installation position
• Inspection box or car roof wiring photo if available
• Door operator wiring connection if related
• Whether KLS-TCD-02A appears on the old system document
• Existing elevator fault description from the maintenance technician

For this board, the installation position is especially important. A board installed on the car top should not be confused with a COP board inside the car panel or a main control board inside the machine cabinet.

Replacement and Site Check Notes

Do not select KLS-TCD-01A only by appearance.

CANNY elevator car-top boards may have similar PCB size or connector style, but the signal definition, wiring arrangement, and system configuration may be different. Before installation, technicians should compare the old and new board carefully and check the surrounding wiring condition.

If the original board was damaged by unstable power, water or moisture, connector oxidation, wiring short circuit, or external signal fault, replacing only the PCB may not fully solve the problem.

For overseas buyers, sending clear photos of the original KLS-TCD-01A board, the full car-top control area, connector terminals, and related wiring is the safest way to confirm the correct replacement before shipment.
