System Communication Fault

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.

• 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.

Click steps to track your progress.

1. 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. 2

   Verify the nominal supply voltage at the power input terminals of all involved communication modules and control cards.

3. 3

   Check the status and diagnostic LEDs on the main control unit, communication modules, and connected intelligent devices for any fault indications.

4. 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.
