Transmitter Variables
For more information about configuring transmitter outputs, see
Section 10
, page 107.
• If the milliamp output represents a flow rate, change the
measurement units for the flow rate: Open the Configure menu, then
choose Transmitter Variables. Choose a new unit of measure from
the units list box under Mass Flow or Volume Flow. For more
information about configuring measurement units and other
transmitter variables, see
Chapter 9
.
Frequency output saturated
If Frequency Output Saturated switches ON, open the View menu, then
choose Output Levels to open the Output Levels window.
If the flow rate is outside control limits:
use a control device to
decrease the flow rate.
If the flow rate is within control limits:
set the flow loop for manual
operation, then follow one of these procedures to change the span of the
frequency/pulse output:
• Rescale the frequency/pulse output: Open the Configure menu, then
choose Transmitter Outputs. Enter new values into the Frequency
and Rate text boxes. For more information about configuring
transmitter outputs, see
Chapter 10
.
• Change the measurement units for the flow rate: Open the Configure
menu, then choose Transmitter Variables. Choose a new unit of
measure from the units list box under Mass Flow or Volume Flow. For
more information about configuring measurement units and other
transmitter variables, see
Chapter 9
.
Example:
Given:
An RFT9739 is configured to measure temperature in degrees
Celsius (°C). The milliamp output is configured so that 20 mA
represents 80°C. The milliamp output goes out of range (high) at 20
mA.
Problem:
When the process fluid temperature exceeds 80
°
C, the
milliamp (analog) output is saturated.
Solution:
Change the span of the milliamp output. Increase the
temperature indicated by the output at 20 mA to 100
°
C.
