2.6
Basic configuration of the transmitter
The 644 must be configured for certain basic variables in order to be operational. In many cases,
all of these variables are pre-configured at the factory. Configuration may be required if the
transmitter is not configured or if the configuration variables need revision.
2.6.1
Mapping the HART variables
Mapping the HART variables with a Field Communicator
The “Variable Mapping” menu displays the sequence of the process variables. Select the
sequence below to change this configuration. The 644 single sensor input configuration screens
allow selection of the primary variable (PV) and the secondary variable (SV). When the Select PV
screen appears Snsr 1 must be selected.
The 644 dual-sensor option configuration screens allow selection of the primary variable (PV),
secondary variable (SV), tertiary variable (TV), and quaternary variable (QV). Variable choices
are Sensor 1, Sensor 2, Differential Temperature, Average Temperature, Terminal Temperature,
and Not Used. The 4-20 mA analog signal represents the Primary Variable.
From the
HOME
screen, enter the Fast Key sequence.
