Failure to follow these installation guidelines could result in death or serious injury.
Make sure only qualified personnel perform the installation.
Explosions could result in death or serious injury.
Do not remove the transmitter cover in explosive atmospheres when the circuit is live.
Before connecting a communicator in an explosive atmosphere, make sure the instruments in the
loop are installed in accordance with intrinsically safe or non-incendive field wiring practices.
Both transmitter covers must be fully engaged to meet explosion-proof requirements.
Verify the operating atmosphere of the transmitter is consistent with the appropriate hazardous
locations certifications.
Electrical shock could cause death or serious injury.
If the sensor is installed in a high-voltage environment and a fault or installation error occurs, high
voltage may be present on the transmitter leads and terminals.
Use extreme caution when making contact with the leads and terminals.
Process leaks could result in death or serious injury.
Install and tighten all four flange bolts before applying pressure.
Do not attempt to loosen or remove flange bolts while the transmitter is in service.
Replacement equipment or spare parts not approved by Emerson for use as spare parts could reduce
the pressure retaining capabilities of the transmitter and may render the instrument dangerous.
Use only bolts supplied or sold by Emerson as spare parts.
Improper assembly of manifolds to traditional flange can damage sensor module.
For safe assembly of manifold to traditional flange, bolts must break back plane of flange web (i.e., bolt
hole) but must not contact module housing.
Sensor module and electronics housing must have equivalent approval labeling in order to
maintain hazardous location approvals.
When upgrading, verify sensor module and electronics housing certifications are equivalent.
Differences in temperature class ratings may exist, in which case the complete assembly takes the
lowest of the individual component temperature classes (for example, a T4/T5 rated electronics housing
assembled to a T4 rated sensor module is a T4 rated transmitter.)

Note
All screens in this section are shown using the RTIS. Edited information is not sent to the transmitter until
the Send button is selected.
2.4.1 Units of measure and damping
Fast Keys
The damping command changes the response time of the transmitter; higher values can smooth
variations in output readings caused by rapid input changes. Determine the appropriate damping setting
based on the necessary response time, signal stability, and other requirements. The damping command
utilizes floating point configuration allowing the user to input any damping value between 0 and 60
seconds.
The units and damping for each process variable may be edited by selecting Manual Setup in the menu
tree and then the appropriate tab as detailed below:
Under the Differential Pressure tab, the Units and Damping for the Differential Pressure may be edited.
Under the Static Pressure tab, the Units and Damping for the Static Pressure may be edited.
Units: 2, 1, 1, 2
Damping: 2, 1, 1, 3

Configuration
Reference Manual
00809-0100-4088, Rev DB
Note
Both absolute and gage pressure are available as variables. The type of transmitter ordered will
determine which variable is measured and which is calculated based on the user defined atmospheric
pressure. For more information on configuring the atmospheric pressure, see “Static pressure” on
page 16. Since only one of the static pressures is actually being measured, there is a single damping
setting for both variables which may be edited under the Static Pressure tab.
Under the Process Temperature tab, the Units and Damping for the Process Temperature may be edited.
Under the Module Temperature tab, the Units for the Module Temperature may be set. The sensor
module temperature measurement is taken within the module, near the differential pressure and/or
static pressure sensors and can be used to control heat tracing or diagnose device overheating.

The LCD display features a four-line display. The first line of five characters displays the output
description, the second line of seven digits displays the actual value, and the third line of six characters
displays engineering units. The fourth line displays “Error” when there is a problem detected within the
transmitter. The LCD display can also display diagnostic messages. These diagnostic messages are listed
in “Alarms and conditions” on page 115.
The Display tab allows the user to configure which variables will be shown on the LCD display. Click the
check box next to each variable to select a variable for display. The transmitter will scroll through the
selected variables, showing each for three seconds as a default setting.

The Display tab includes three types of display options (information that appears on the LCD display)
including Device Variables, User-Defined Parameters, or User-Defined Variables.
Device variables
The device variables include Differential Pressure, Absolute Temperature, Gage Pressure, Process
Temperature, Module Temperature, Device Address or Baud Rate. These display variables can be selected
or deselected on the left column of the Display Options heading.
User-defined parameters
The User-Defined Parameters fields are for pieces of information the device can store for reference. The
device will not modify or update these parameters but they can be written by the user or a host system to
be displayed on the LCD display and include Beta Ratio, Pipe Schedule, or Orifice Bore. If the device loses
power at any point during operation, these values are stored in memory and will not be lost.

User-defined variables
Note
Only the value of the user-defined variables should be written on a periodic basis. Regular writes to the
other parameters may cause the device memory to fail.
The User-Defined Variable fields are for pieces of information that the device can store for a live reference
of the application status or production levels, via Modbus. The device itself will not modify or update
these variables; rather this is intended to be a live value sent to the device from a host, such as a flow
computer or Remote Terminal Unit (RTU). This information can then be displayed on the device's LCD
display and include variables such as Last 24-Hours of Gas Volume or Instantaneous Flow Rate.
To configure User-Defined Variables, select Configure User-Defined Variables. A screen will appear as
shown below:

Similar to the User-Defined Parameters screen, you can input a label and unit for each variable, however
the value will be written by the flow computer or host. The user must program the flow computer or host
separately to write the value to the device. If the device loses power at any point during operation, the
value will be lost, but the Label and Units will not be lost.
Note
If the transmitter is ordered without an LCD display, the User-Defined Parameters and User-Defined
Variables are still available but are configured through the User-Defined Data tab in Manual Setup rather
than accessing them through the Display tab.
