When confirming this board, buyers should check more than the front appearance. KM51070342G03 and KM51070342G05 may belong to the same board family, but the version, connector layout, PCB revision, component arrangement, or site configuration may be different.

Useful confirmation details include:

• old board label photo

• KM51070342G03 or KM51070342G05 marking

• EMB 501-B marking

• front and back PCB photos

• connector and plug close-ups

• installation position inside the escalator controller

• fault code or failure description

• photos of any burning, corrosion, or damaged terminals

This board may be replaced when the escalator has control system faults, signal errors, unstable operation, communication problems, damaged connectors, or visible PCB failure. If the fault remains after replacement, technicians should also check wiring harnesses, power supply, sensors, safety circuit connections, grounding, and related escalator control boards.

For buyers in Saudi Arabia, Jordan, Egypt, UAE, Kuwait, Brazil, Chile, Spain, and Italy, clear old-board photos and complete model confirmation are recommended before shipment. This helps reduce wrong supply and supports faster KONE escalator maintenance work.
