RUN Mode and PROGRAM Mode
SITRANS LR 200 has 2 modes of operation: RUN and PROGRAM.
After you complete the installation procedures and power up SITRANS LR 200, it starts in RUN
mode and detects the distance to the material level in meters. This is the default start-up
display mode.

Use the hand programmer to control the display.
Whenever a loss of echo occurs, LOE flashes and the Reliable Echo indicator is replaced by
the Unreliable indicator. Before the Failsafe Timer expires, the letters LOE (Loss of Echo)
alternate with the reading every two seconds. Once the Failsafe condition is established, LOE
is displayed permanently. When a valid reading is received, the level reading display returns to
normal operation.
