Troubleshooting 

The Remote Operator display and status indication LEDs can indicate abnormal operating and 
system conditions.   

Display 
Indication 

Problem 

Possible Solution 

nEt

 on 

display 

A loss of communication 
has been detected on the 
RS485 link to the network. 

The Remote Operator has an RS485 Network Timeout 
Protection setting (Parameter 3). This error is reported when 
no communication occurs for longer than the timeout setting.  
The system will become active as soon as communication is 
restored. 
To clear 

nEt

 from the display, press the Data/Prog pushbutton 

momentarily or send a Reset command from the network 
Master.
