5.1Checking the Normal Display
Place the selector switch in “LOCAL” or “REMOTE” position. The valve position will be indicated at the top of the LCD. “STATUS OK” or “DNET COMM LOSS” should be indicated at the bottom of the LCD display.
If “STATUS OK” is displayed, the DNFU is communicating with the DeviceNet network.
If “DNET COMM LOSS” is displayed, no communication is occurring. This could be due to a number of factors, including problems with the host DeviceNet system and/or network. Check all local connections and configurations. Confirm that the host is connected, configured for baud rate, protocol to match DeviceNet, and operational. See also Section 7, Troubleshooting.
