Rosemount 148

CONFIGURATION
The Rosemount 148 must be configured for certain basis variables to operate.
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.
Configuration consists of testing the transmitter and verifying transmitter
configuration data. The Rosemount 148 must be configured before
installation. This can be done two ways: ordering factory-configuration by
Emerson, or using the Rosemount 148 PC Programmer interface in a bench
configuration setting.

The Rosemount 148 PC Programmer exchanges information with the
transmitter in a bench configuration setting through a personal computer and
interface box. Connect the 148 PC Programmer to the computer. Then using
the included test leads connect the 148 PC Programmer interface to the
power/communication terminals on the 148 transmitter making sure the
polarity is correct.
Install the 148 PC Program, included on compact disc, and then start the
program. The device can be configured from the main screen, and will also
show the current transmitter status. The following pages detail the settings
that can be configured on the Rosemount 148.
Configuring with the 148
PC Programmer
In order to operate properly, the Rosemount 148 has basic variables that
need to be configured. Some of the variables are factory configured, however,
some of the variables may need to be initially set up or revised. The first two
tabs on the main screen are
Basic
and
Advanced
Settings, which include all
of the configuration variables that can be set for the Rosemount 148. Any
changes to the configuration must be sent to the transmitter by clicking the
Send to Transmitter button on the right of the screen. The current
configuration of the connected 148 may be viewed by clicking the Load From
Transmitter button.
Transmitter Identification
The Tag variable is the easiest way to identify/distinguish between
transmitters. It can be used to label transmitters electronically according to the
requirements of the application. The tag may be up to eight characters in
length, and does not impact the measurement of the transmitter.
