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.
RUNModeDisplay
Use the hand programmer to control the display.1
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.
PROGRAM Mode Display2
1 – Primary Reading (displays level, distance, or volume1, in either units or percent).
2 – Secondary Reading (displays Parameter number for Auxiliary Reading2)
3 – Echo status indicator: Reliable Echo or Unreliable 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.)

7. Minimize false reflections: Set P838 (Auto False Echo Suppression Distance)
8. Enable False Echo Suppression: set P837 (Auto False Echo Suppression)
Using P837 and P838 (perform this function at low tank levels)
The TVT (Time Varying Threshold) curve sets a threshold which screens out false echoes2. If
SITRANS Probe LU displays an incorrect full level, or if the reading fluctuates between a false
high level and a correct level, use P838 and P837 together to elevate the TVT (Time Varying
Threshold) in this region and de-sensitize the receiver from any ‘base noise’ caused by internal
transducer reflections, nozzleechoes, or other vessel false echoes3.

1. Default settingfor Blankingis0.25 m(10").
Notes:
• Setting P006 resets Span, if it has not previously been set to a different value.
• The default setting for Span is based on Operation (P001) and Empty (P006). Span is set to
Empty minus 110% of Blanking distance1, unless Operation is set to distance (P001=3). In
this case, Span is set to Empty distance.
• Always prevent the monitored surface from approaching within 0.3 m (1 ft) of the
transducer face. This provides a 0.05 m (2") safety margin, as 0.25 m (10") is the minimum
distance detectable.
