Emerson 9739 Manuel D’Utilisation
Procedure
1.
Set Frequency Output Fault Action as desired.
The default value is Downscale (0 Hz).
2.
If you set Frequency Output Fault Action to Upscale, set Frequency Fault Level to the desired
value.
value.
The default value is 15000 Hz. The range is 10 to 15000 Hz.

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
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
Output Fault Action
to None. If you try to do this, the transmitter will not accept the configuration.
6.3
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.
output parameters control which condition is reported and how it is reported.
The discrete output parameters include:
•
Discrete Output Source
•
Discrete Output Polarity
•
Discrete Output Fault Action
•
Discrete Output Power Source
Integrate the meter with the control system
