OVERVIEW

The LCD meter provides local indication of the output, and
abbreviated diagnostic messages governing transmitter
operation. The meter is located on the electronics board side of
the transmitter, and receives its output information directly from
the electronics board microprocessor. An extended cover is
required to accommodate the meter.

The meter features a two-line display that accommodates five
digits for reporting the process variable on the top line, and six
characters for displaying engineering units on the bottom line.
And in addition to units of pressure, the new LCD meter is
capable of displaying flow and level units. The meter uses both
lines to display diagnostic messages. You can configure the
meter to display the following information:

䡲 Engineering Units
䡲 Percent of Range
䡲 User-Configurable LCD Scale
䡲 Alternating between any two of the above

The user-configurable scale is a new feature that enables you to
configure the LCD meter to a custom scale for flow or level. You
can configure the meter using a Model 275 HART Communicator
or AMS. With the user configurable scale feature, you can define
the decimal point position, the upper range value, the lower range
value, the engineering units, and the transfer function.

The user-configurable meter scale transfer function is independent
of the transmitter analog output transfer function, which allows the
meter to display square root flow output while the analog output
remains linear with the pressure input.

SAFETY MESSAGES

Procedures and instructions in this manual may require special
precautions to ensure the safety of the personnel performing the
operations. Information that raises potential safety issues is indicated
by a warning symbol ( ). Refer to the following safety messages
before performing an operation preceded by this symbol.

Explosions can result in death or serious injury.

• Do not remove the transmitter covers in explosive
atmospheres when the circuit is alive.

• Both transmitter covers must be fully engaged to meet
explosionproof requirements.

• Before connecting a communicator in an explosive
atmosphere, make sure the instruments in the loop are
installed in accordance with intrinsically safe or nonincendive
field wiring practices.

INSTALLATION PROCEDURES

The installation procedures vary depending on the style of
housing and the meter kit. Examine your meter part numbers
closely to ensure that you perform the appropriate procedure.

Part Numbers 03031-0193-0101 and 03031-0193-0111

The meter kit includes:

䡲 one LCD meter display
䡲 one extended cover with O-ring
䡲 two captive screws
䡲 one ten-pin interconnection header

Use the following procedure and Figure 3 to install the LCD meter.

NOTE

The LCD meter and the electronics board are
electrostatically sensitive; observe handling precautions for static­sensitive components.

1. If the transmitter is installed in a loop, secure the loop and
disconnect power.

2. Rotate the electronics housing up to 180 degrees (left or
right) to improve field access to the two compartments or
to better view the LCD meter. To rotate the housing,
release the housing rotation set screw and turn the
housing not more than 180 degrees from the orientation
shown in Figure 1 on page 2. To rotate the housing greater
than 180 degrees, refer to the Model 3051 product
manual, publication number 00809-0100-4001.

3051-3031A05A

NOTE

Do not rotate the housing greater than 180 degrees without first
referring to the Model 3051 product manual. Rotating the housing
greater than 180 degrees will damage the sensor module and
void the Rosemount warranty.

See “Safety Messages” on page 6 for complete warning information.
