RUN Mode and PROGRAM Mode
SITRANS Probe LR has two modes of operation: RUN and PROGRAM.
After you complete the installation procedures and power up SITRANS Probe LR, it starts in
RUN mode and detects the material level. It returns the distance (in meters) to the material
level referenced from Empty (process empty level). This is the default start-up display mode.
RUN Mode Display
Use the hand programmer to control the display.
6
1 – Primary Reading (displays level, distance, or volume, in either units or percent)
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,
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.

• Set parameters to suit your specific application.
• Activate PROGRAM mode at any time, to change parameter values and set operating
• For local programming, use the Siemens hand programmer.
