C2.2.4.1
Selection can be made, which event will trigger a signal on the status output.
Select:
- Flow Totalizer Overfl.: Signal is sent, when pre-defined flow totalizer value is reached.
Define value in C4.1.2.
- Energy Totalizer Overf.: Signal is sent, when pre-defined energy totalizer value is
reached. Define value in C4.2.2.
- Failure: Status signal is sent in case of failure.
- Function Check: Status signal is sent, if a test function is active.
- Out of Specification: Signal is sent, if measurement is out of specification.
- Type of Fluid (for steam applications): Signal is sent to signalise transition in type of
fluid.
C2.2.4.2 Type of Fluid
Only available, if "Type of Fluid" is selected in C2.2.4.1.
Select (availibility depending on fluid and medium configuration):
- Liquid: Indicates transition of medium to liquid.
- Saturated Steam: Indicates transition of medium to saturated steam.
- Superheated Steam: Indicates transition of medium to superheated steam.
Note: Correct temperature and pressure sources have to be defined in C1.6 and C1.7!
C2.2.4.3 Type of Fluid Epsilon
Only available, if "Type of Fluid" is selected in C2.2.4.1.
Value defines the sensitivity of transition detection.
Enter value between -1.0 (to decrease sensitivity) and +1.0 (to increase sensitivity).
C2.2.5 Limit Switch
Only available, if "Limit Switch" is selected in C2.2.1.
C2.2.5.1 Measurement
Limit output variable can be defined, which will trigger a signal on the status output.
Select: Volume Flow / Norm. Volume Flow / Mass Flow / Volume / Density /
Temperature1 / Temperature2 / Pressure / Vortex Frequency / Velocity / Specific
Enthalpy / Specific Heat Capacity / Reynolds Number / Mass / Norm. Volume / FAD /
Net Energy / Gross Energy / Net Power / Gross Power
The latter five measurement variables are just available if the respective meter type
option was activated and fluid/medium were properly configured.
Availability of selection depending on meter type and medium configuration.
C2.2.5.2 Lower Limit
Enter value for lower limit in unit according to selected limit output variable.
C2.2.5.3 Upper Limit
Enter value for upper limit in unit according to selected limit output variable.
C2.2.6 Invert Signal
Select: On (normally open) / Off (normally closed)

C3 Communication
C3.1 HART
C3.1.1 Current Loop Mode
Select: On (enables primary variable to be transmitted as 4…20 mA current values) / Off
(disables 4…20 mA transmission, but enables HART
®
multi-drop mode)
C3.1.2 Identification
HART
®
Identification parameters
C3.1.2.1 Polling Address
Set address for HART
®
operation. Standard setting is 000 for point-to-point operation
with current output 4…20 mA. Setting of polling address
000 causes a constant 4 mA
output and enables multi-drop mode.
Enter: 000…063
C3.1.2.2 Tag
Enter measuring point identifier (1…8 digits).
