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.
