Problem Possible Solution
nEt on display A loss of communication has
been detected on the RS485
link to the network. The Remote Keypad has an RS485 Network Timeout Protection setting ( Pr 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.
