If your primary sensor fails, there will be a seamless transition where the second sensor
immediately takes over the process. The transmitter will report a Failed status, indicating
Sensor 1 is open and Hot Backup is active. This alert is shown on the Field Communicator
in the Overview section.
Select 1 Device Status to view the active alerts.
After the sensor has been repaired or replaced, the Field Communicator will display a
Maintenance Device Status, indicating Hot Backup is still active. This is shown on the Field
Communicator in the Overview section.
