6-3-2 :Functions of SFC
Introduction
The functions available with the SFC include functions directly assigned to the respec-
tive keys and CONFIG functions that are entered by pressing the CONF key.
6-3-2-1 Key assigned functions
The following are the functions directly assigned to the SFC keys.
6-3-2-2 CONFIG functions
An SFC has the following major dedicated functions:
• Display and change the output format
• Display and change the display format
•Save data
• Display and change the low-flow cutoff value
• Display sensor temperature
• Display PROM No.
6-3-3 :Hierarchic structure of CONFIG functions
6-3-3-1 Hierarchic structure chart
The CONFIG functions form a hierarchic structure. Before using the CONFIG func-
tions, check the positions of the respective sub-functions with the supplied hierarchic
structure chart.
The SFC screen displays only two lines, and so if it is not clear which hierarchy is
shown, see the hierarchy chart on page 6-13.
ID/DE READ : Starts communication.
INPUT : Reads the real measured value of flow rate and sets the spe-
cific gravity.
OUTPUT : Reads the output of the transmitter in percentage or outputs
a constant current from the transmitter.
STAT : Displays self-diagnostics result of the transmitter.
PRINT : Prints out internal data of the transmitter.
ACT PR : Continuously prints out response result.
A DE : Switches between digital and analog outputs.
DE CONF : Selects an output format of digital signal.
LRV, URV, SPAN : Displays or sets the output range.
UNIT : Sets engineering units or sets specific gravity.
DAMP : Sets a damping time constant.
