  • Page 24: Operating Sitrans Probe Lr

    SITRANS Probe LR has two modes of operation: RUN and PROGRAM. RUN Mode SITRANS Probe LR 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).

  • Page 25: Program Mode

    Activate PROGRAM mode at any time, to change parameter values and set operating conditions. • For local programming, use the Siemens handheld programmer. • For programming from a distance, use either a PC running SIMATIC PDM, or a HART handheld communicator.

  • Page 26: Low Temperature Effects On Run/Program Modes

    RUN mode will operate normally, with the following exceptions: • handheld programmer operation is disabled • the LCD displays only limited information: the bar graph and the reliable/ unreliable echo indicator PROGRAM mode: • handheld programmer operation is disabled Page 20 SITRANS Probe LR – INSTRUCTION MANUAL 7ML19985HR02...

  • Page 97: Maintenance

    Maintenance SITRANS Probe LR requires no maintenance or cleaning under normal operating conditions. Under severe operating conditions, the antenna may require periodic cleaning. If cleaning becomes necessary: • Note the antenna material and the process medium, and select a cleaning solution that will not react adversely with either.

    (P801) as % P006 Near Blanking Near Blanking programs SITRANS Probe LR to ignore the zone in front of the antenna. The default blanking distance is 0.3 m (1 ft) plus any shield length, from the reference point P800 allows you to increase the near blanking value from its factory setting. But Auto False-Echo Suppression (P837) is generally recommended in preference to extending the blanking distance from factory values.

  • Page 100: Range Extension

    SITRANS Probe LR will ignore false echoes in your application. P838 allows you to set a distance, and P837 then instructs SITRANS Probe LR to "learn" where the obstructions/false echoes are within that distance. If possible, rotate the instrument before using Auto False-Echo Suppression, to lower the amplitude of false echoes.

Chemical compatibility The plastic materials used in the construction of SITRANS Probe LR (polypropylene, , and PEI ) are resistant to attack from most chemicals. For exposure to specific environments, check with chemical compatibility charts before installing and operating SITRANS Probe LR in your application.
