What to do if LED2 is out and LED1 is lit on Sensia Measuring Instruments?

If LED2 is out and LED1 is lit on your Sensia Measuring Instruments, observe the display. If serial or Ethernet communications are functioning, confirm that the device has a valid setup file, as the software will not run if the setup file is corrupted. A bad setup file is indicated on the display and in the Modbus registers. If the setup file is acceptable, review the power supply voltages on the MXR and CTC via Modbus registers. If these power supply values are within specification, then contact Sensia.
