Emerson Micro-Motion 2400S - Configuring the Frequency Output

48 Micro Motion

Model 2400S Transmitters with Analog Outputs
Required Transmitter Configuration
6.6 Configuring the frequency output
Note: This section is applicable only if Channel B has been configured as a frequency output. See
Section 6.3.
The frequency output generates two voltage levels:
•0 V
• A site-specific voltage, determined by the power supply, pull-up resistor, and load (see the
installation manual for your transmitter)
If Channel B is configured as a frequency output, you must configure the parameters listed in
Table 6-11. Table 6-11 also shows the names used for each parameter by the display, ProLink II, and
the Communicator.
To configure the frequency output, see the menu flowcharts in Figure 6-6. For details on frequency
output parameters, see Sections 6.6.1 through 6.6.5.
Note: If you use the display to configure the frequency output, you can configure only the process
variable and the parameters used by the Frequency = Flow scaling method. To configure other
frequency output parameters, use ProLink II or the Communicator.
