TROUBLESHOOTING
E-S
E-5 [E3:01] Abnormality in network reception system is displayed
*
*
*
*
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.
