Startup; Startup Display (Run Mode) - Siemens SITRANS LR200 Instruction Manual

Startup

Only two steps are necessary for a Quick Setup (see page 21 for detailed instructions):
1. Use the hand programmer to set the PROFIBUS address locally.
2. Use SIMATIC PDM to calibrate the four set points: High and Low Calibration Point,
and High and Low Level Point.
SITRANS LR 200 automatically starts up in RUN mode and detects the material level. The
LCD displays the material level referenced from the Low Level Point
Analog Input Function Block 1/AIFB1). System status is displayed on the LCD, or on a
remote communications terminal.
Note:
SITRANS LR 200 (PROFIBUS PA) continues to monitor in and out values even
when the device is in PROGRAM mode.
