HART Comm.
NOTE
Information and procedures in this section that make use of HART
Communicator fast key sequences assume that the transmitter and
1, 5
communicator are connected, powered, and operating correctly. If you are not
familiar with the HART Communicator or fast-key sequences, refer to
Appendix A: HART Communicator.
Before you place the transmitter into operation, it is recommended that you
review the transmitter configuration data that was set at the factory. You
should review the following configuration data:
Transmitter Model
Tag
Date
Message
Minimum Span
4 and 20 mA points
Damping
Security Setting (on, off)
Integral Meter
Isolator Material
O-Ring Material
Remote Seal (type, fill fluid,
isolator material, number)
Address
Before performing other transmitter on-line operations, review the digital
output parameters to ensure that the transmitter is operating properly and is
configured to the appropriate process variables.
The process variables for the Rosemount 3051N provide the transmitter
output, and are continuously updated. The process variable menu displays
2
the following process variables:
•
Pressure
•
Percent of Range
•
Analog Output
The pressure reading in both Engineering Units and Percent of Range will
continue to track with pressures outside of the defined range from the lower to
the upper range limit of the sensor module.
