Power up

Power up the device. A transition screen showing first the Siemens logo and then the current
firmware revision is displayed while the first measurement is being processed. SITRANS
LR250 automatically starts up in Measurement mode. The first time the device is configured,
you will be prompted to select a language (English, German, French, Spanish or Chinese).To
change the language again, see Language (7.).
Press Mode
[If the SITRANS LR250 FF is to be used in an FF application, configure using a network
configuration tool, such as DeltaV or NI-FBUS Configurator. See Quick Start Wizard via AMS
Device Manager (Page 71).]
Follow these steps to configure the device via the LUI:
• Complete the Quick Start Wizard [see Quick Start Wizard via the handheld programmer
(Page 54)]. Completing the Quick Start Wizard or writing any parameter via the LUI causes
the device to begin measuring. The Resource Block (RES) and Level Transducer Block (LTB)
will move to Automatic mode.
• AIFB 1 and AIFB 2 will remain Out of Service (as displayed on the LCD). These blocks can
only be configured and scheduled using a network configuration tool. For more details,
see System Integration in manual Foundation Fieldbus for Level Instruments
(7ML19985MP01).
Note
The last step of the Quick Start run from the LUI will place the RESOURCE block in Automatic
mode.

Handheld programmer functions

parameters. The settings can be modified locally via the Local User Interface (LUI) which
consists of an LCD display and a handheld programmer.
A Quick Start Wizard provides an easy step-by-step procedure to configure the device for a
simple application. Access the wizards:
• locally [see Quick Start Wizard via the handheld programmer (Page 54)]
• or from a remote location [see Quick Start Wizard via AMS Device Manager (Page 71)]
For more complex setups see Application Examples (Page 58), and for the complete range of
