1 Overview
The Rosemount™ 628 Wireless Gas Monitor is compatible with the
Rosemount 928 Wireless Gas Monitor.
The sensor fits integrally into the transmitter without the use of tools.
Make electrical connections when the sensor module is fully seated in
the transmitter sensor housing.
Note
Use Rosemount 628 Universal Gas Sensor only with the Rosemount
928 Transmitter.
CAUTION
The Ingress Protection (IP) filter must be installed.
If the IP filter is not installed, then damage may occur to the sensor
inside the Rosemount 628 Universal Gas Sensor.
Do not operate the transmitter without the correct IP filter
installed in the sensor module.
When installing the IP filter, verify that the IP filter gasket is in
place, is properly aligned, and does not block the white filter
media. Refer to Figure 1-1.
When handling the IP filter, avoid contact with the filter media.
Verify all three legs are fully latched by pushing upward on IP
filter leg.
Avoid getting water inside the IP filter.
Do not attempt to clean the IP filter.
Do not rinse or spray the IP filter with water.
Do not immerse the IP filter in water.

2 Install the sensor
The sensor is held in place using a tight-fitting seal and snap
connections. The sensor is connected to the transmitter by two
latching tabs that fit into the bottom portion of the housing as shown
in Figure 2.1. The seal between the transmitter housing and the
sensor assembly is designed to achieve a snug, airtight fit between
the two assemblies when properly installed.
Procedure
1. Remove the sensor from its packaging.
2. If installing a sensor on the transmitter for the first time, then
remove the protective plastic cap from the sensor housing at
the bottom of the transmitter.
3. Before installing the module into the transmitter, confirm the
keying feature is aligned by rotating it into position.
4. Slide the sensor assembly up into the transmitter housing until
it is completely seated.
Note
The sensor contains a keying feature ensuring it cannot be
forced into the transmitter housing in an incorrect alignment.

5. To ensure a firm latch and seal, push the module upward until
the two latching tabs are fully engaged. After they are seated,
push up on th bottom of each of the latching tabs.
6. Allow the transmitter to warm-up before continuing.
Refer to the following table for maximum warm-up times
based on gas type. During the warm-up period, the displayed
values, alerts, and gas concentrations will not reflect actual
measurements; readings will not be transmitted.
Table 2-1: Maximum warm-up times
Gas type Maximum warm-up period
Hydrogen sulfide (H2S) One minute
Oxygen (O2) Seven minutes
Carbon monoxide (CO) One minute

3 Bench configuration
To configure, you must install the sensor in a functional transmitter.
The transmitter receives any HART® communication from a handheld
Field Communicator or from an AMS Wireless Configurator.
Remove the rear housing cover to expose the terminal block and
HART communication terminals; then connect the power module to
power the device for configuration.
3.1 Bench configure using a Field Communicator
A transmitter Device Description (DD) is required for HART®
communication.
To connect to the transmitter using a handheld communication
device, refer to Guided setup. To obtain the latest DD, go to
EmersonProcess.com/DeviceFiles and then visit the Emerson web
page for your handheld device.
Procedure
1. On the Home screen, select Configure.
2. Do one of the following:
•On the Configure screen, select Guided Setup to verify
or change initial configuration settings. Refer to Guided
setup. Refer to the Field Communicator subsections for
each configuration task.
•On the Configure screen, select Manual Setup to verify
or change all configuration settings, including optional
advanced settings. Refer to the Manual Setup section in the
Rosemount 928 Wireless Gas Monitor Reference Manual.
Refer to the Field Communicator subsections for each
configuration task.
3. When finished, select Send to implement configuration
changes.
4. When configuration is completed, remove the HART®
communications leads from the COMM terminals on the
terminal block and replace the rear housing cover.
3.2 Bench configure AMS Wireless Configurator
AMS Wireless Configurator is capable of connecting to devices
directly, using a HART® modem, or though a Wireless Gateway.
Procedure
1. In the AMS Device Manager pane, select the HART modem.
