KONE KDL16R Brake Control Board KM946246G02 KM946247H05

KONE KM946246G02 is a brake control PCB used inside compatible KONE KDL16R elevator drive systems. The board is also identified by the PCB reference KM946247H05 and is commonly marked BCK on the original circuit board. It is an internal drive module rather than a complete KDL16R inverter.

What to Check on the Removed Board

For this part, the most useful information is usually found directly on the old PCB. Check whether the assembly label shows KM946246G02 and whether KM946247H05 is printed on the board itself.

Photos should clearly show:

• the complete assembly label

• KM946247H05 PCB marking

• BCK identification

• plug and terminal positions

• front and rear component layout

• the KDL16R inverter nameplate

• any burnt, cracked, or repaired area

Boards from the same drive family can look very similar, but a different PCB revision or connector layout may not suit the installed inverter. The part number should therefore be matched together with the drive model and original-board photos.

Replacement enquiries often follow brake-control faults, damaged components, connector failure, visible overheating, or troubleshooting inside the KDL16R drive. Before fitting another board, technicians should also inspect the brake coil, related wiring, terminals, power supply, contactor, and drive parameters.

Installation and testing should be completed by qualified elevator technicians. Brake release, brake holding, drive operation, and elevator safety functions must be checked before returning the unit to service.

Customers in Saudi Arabia, Jordan, Egypt, Iraq, Lebanon, Brazil, Colombia, Spain, and Italy can send the old-board photos and KDL16R nameplate for part confirmation before shipment.
