Volume Values
Range: 0.0 to 9999999.0
Default: 0.0
Enter up to 32 level breakpoints, where the corresponding volume is known. The values
corresponding to 0% and 100% levels must be entered, and breakpoints can be ordered
from top to bottom, or the reverse.
Breakpoints are grouped into four tables: Table 1-8, Table 9-16, Table 17-24, and Table 25-
32.
Entering breakpoints via SIMATIC PDM:

Entering breakpoints via the local push buttons:
1. The default unit for level values is m: to change it navigate to Setup (2.) (Page 168) >
Sensor (2.1) (Page 168) > Units (2.1.1.) (Page 168) , and select the desired unit.
2. Navigate to Setup (2.) (Page 168) > Volume (2.6.) (Page 179
) > Table 1-8 (2.6.7.), and
enter the value.
3. Go to the appropriate table for the particular breakpoint you wish to adjust: for example,
go to Table 1-8 for breakpoint 1.
4. Under Table 1-8, go to Level 1 (2.6.7.1.) (Page 183) to enter the level value for the
breakpoint 1.
5. Under Table 1-8, go to Volume 1 (2.6.7.2.) (Page 183) to enter the volume value for the
breakpoint 1.
6. Repeat steps 3 to 5, until values have been entered for all required breakpoints.
