C-9
[E2:18] Network response overtime error is displayed
j, This troubleshooting is carried out when there is still an abnormality, so when disconnecting the
connector and inserting the T-adapter, or when removing the T-adapter and returning the connector
to its original position, if the service code is not displayed, the problem has been removed.
* If the starting switch is turned ON when there is a disconnection in the wiring harness between the monitor
panel and the controller, or the positive end (+) of the network wiring harness or the inside of the controller
are short circuited, the controller cannot carry out networking, so the monitor panel does not display any
abnormality.
*
Before carrying out troubleshooting, check that all the related connectors are properly inserted.
* Always connect any disconnected connectors before going on to the next step.
