Kone · Elevator Control
What does 02 mean?
A communication error has occurred within the machine's control system, indicating a failure to exchange data between critical components. This fault disables all motion functions.
Common Causes
- Interruption or failure in communication channels (e.g., CANbus) between critical system components.
- Damaged wiring or loose connections in the communication network.
- Failure of a communication module or node.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Inspect all communication cables and their connectors for physical damage, proper seating, and correct termination between the main control unit and critical system components.
- 2
Verify the nominal supply voltage at the power input terminals of all involved communication modules and control cards.
- 3
Check the status and diagnostic LEDs on the main control unit, communication modules, and connected intelligent devices for any fault indications.
- 4
Verify all communication parameters, such as network addresses, baud rates, and protocol settings, within the Kone elevator control software against the system's documented configuration.
