Notes:
• While the device is in PROGRAM mode the output remains active and continues to
respond to changes in the device.
• Do not use the handheld programmer at the same time as SIMATIC PDM, or erratic
operation may result.
• SITRANS LR250 automatically returns to Measurement mode after a period of
inactivity in PROGRAM mode (between 15 seconds and 10 minutes, depending on
the menu level).
Change parameter settings and set operating conditions to suit your specific application.
