RUN Mode and PROGRAM Mode
SITRANS Probe LU has two modes of operation: RUN and PROGRAM.
SITRANS Probe LU automatically starts in RUN mode when power is applied, and detects the
material level. The primary reading displays the material level (in meters) referenced from
Empty (process empty level). This is the default start-up display mode.
System status is displayed on the LCD, or on a remote communications terminal.
RUN Mode Display
Use the hand programmer to control the display.

1 – Primary Reading (displays level, distance, or volume
2 – Secondary Reading (displays Parameter number for Auxiliary Reading
3 – Echo status indicator: Reliable Echo
4 – Units or Percent
5 – Active bar graph represents material level
6 – Auxiliary Reading (depending on the parameter selected, it displays milliAmp value,
distance, or echo confidence, with units where applicable.)
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.
