Options for Frequency Output Fault Action

Table 6-7:

Label

Frequency output behavior

Upscale

Goes to configured Upscale value:

•

Range: 10 Hz to 15000 Hz

•

Default: 15000 Hz

Downscale

0 Hz

Internal Zero

0 Hz

None

(default)

Tracks data for the assigned process variable; no fault action

CAUTION!

If you set mA Output Fault Action or Frequency Output Fault Action to None, be sure to set Digital
Communications Fault Action

to None. If you do not, the output will not report actual process data,

and this may result in measurement errors or unintended consequences for your process.

Restriction

If you set Digital Communications Fault Action to NAN, you cannot set mA Output Fault Action or Frequency
Output Fault Action

to None. If you try to do this, the transmitter will not accept the configuration.

6.4

Configure the discrete output

The discrete output is used to report specific flowmeter or process conditions. The discrete
output parameters control which condition is reported and how it is reported. Your
transmitter may have zero or one discrete output: Channel B can be configured as a
frequency output or a discrete output.

The discrete output parameters include:

•

Discrete Output Source

•

Discrete Output Polarity

•

Discrete Output Fault Action

Restriction

Before you can configure the discrete output, you must configure a channel to operate as a discrete
output.

Important

Whenever you change a discrete output parameter, verify all other discrete output parameters
before returning the flowmeter to service. In some situations, the transmitter automatically loads a
set of stored values, and these values may not be appropriate for your application.

Integrate the meter with the control system
