Siemens SITRANS Probe LU Kurzanleitung Seite 256

If the echo confidence drops below the echo confidence threshold, the failsafe timer starts
running. When the timer expires, the letters LOE (Loss of Echo) alternate with the reading
every two seconds, and the Reliable Echo indicator is replaced by the Unreliable indicator.
When a valid reading is received, the level reading display returns to normal operation.
