1 Wireless considerations
1.1 Power up sequence
The Smart Wireless Gateway should be installed and functioning properly
before any wireless field devices are powered. Install the Black Power Module,
SmartPower™ Solutions model number 701PBKKF (part number
00753-9220-0001) into the Rosemount 702 Transmitter to power the
device. Wireless devices should be powered up in order of proximity from the
Gateway, beginning with the closest device, then working outward from the
Gateway. This results in a simpler and faster network installation. Enable
Active Advertising on the Gateway to ensure new devices are able to join the
network faster. For more information see the Emerson™ Wireless 1420
Gateway Reference Manual.
1.2 Antenna position
The antenna should be positioned vertically, either straight up or straight
down, and it should be approximately 3 ft. (1 m) from any large structure,
building, or conductive surface to allow for clear communication to other
devices.
Antenna PositionFigure 1-1:
Quick Start Guide April 2018

1.3 Conduit entry
Upon installation, ensure each conduit entry is either sealed with a conduit
plug using approved thread sealant, or has an installed conduit fitting or
cable gland with appropriate threaded sealant. Note the conduit entries on
the Rosemount 702 Transmitter are threaded ½–14 NPT.
Conduit EntryFigure 1-2:

1.4 Field Communicator connections
The power module needs to be installed before the Field Communicator can
interface with the Rosemount 702 Transmitter. This transmitter uses the
Black Power Module; Order model number 701PBKKF or part number
00753-9220-0001.

2 Physical installation
The Rosemount 702 Transmitter can be installed in one of two
configurations:
•Direct mount, where the switch is connected directly to the Rosemount
702 Transmitter housing’s conduit entry.
•Remote mount, where the switch is mounted separate from the
Rosemount 702 Transmitter housing, then connected to the Rosemount
702 Transmitter via conduit.
Select the installation sequence that corresponds to the mounting
configuration.
2.1 Direct mount
Note
Direct mount installation should not be employed when using tubing and
connectors such as Swagelok® fittings.

Procedure
1. Install the switch according to standard installation practices making sure
to use thread sealant on all connections.
2. Attach the Rosemount 702 Transmitter housing to the switch using the
threaded conduit entry.
3. Attach the switch wiring to the terminals as indicated on the wiring
diagram (see Chapter 5).
4. Connect the Black Power Module.
Note
Wireless devices should be powered up in order of proximity from the
Smart Wireless Gateway, beginning with the closest device to the
Gateway. This will result in a simpler and faster network installation.
5. Close the housing cover and tighten to safety specification. Always
ensure a proper seal so the metal touches metal, but do not over tighten.
6. Position antenna vertically, either straight up or straight down. The
antenna should be approximately 3 ft. (0.91 m) from any large structures
or buildings, to allow clear communication to other devices.

2.3 High gain, remote antenna (optional)
The high gain, remote antenna options provide flexibility for mounting the
Rosemount 702 Transmitter based on wireless connectivity, lightning
protection, and current work practices.

WARNING!
When installing remote mount antennas for the Rosemount 702 Transmitter,
always use established safety procedures to avoid falling or contact with
high-power electrical lines.
Install remote antenna components for the Rosemount 702 Transmitter in
compliance with local and national electrical codes and use best practices for
lightning protection.
Before installing, consult with the local area electrical inspector, electrical
officer, and work area supervisor.
The Rosemount 702 Transmitter remote antenna option is specifically
engineered to provide installation flexibility while optimizing wireless
performance and local spectrum approvals. To maintain wireless
performance and avoid non-compliance with spectrum regulations, do not
change the length of cable or the antenna type.
If the supplied remote mount antenna kit is not installed per these
instructions, Emerson is not responsible for wireless performance or non-
compliance with spectrum regulations.
Procedure
1. Mount the antenna on a 1.5 to 2-in. pipe mast using the supplied
mounting equipment.
2. Connect the lightning arrestor directly to the top of the Rosemount 702
Transmitter.
3. Install the grounding lug, lock washer, and nut on top of lightning
arrestor.
4. Connect the antenna to the lightning arrestor using the supplied
LMR-400 coaxial cable ensuring the drip loop is not closer than 1 ft. (0.3
m) from the lightning arrestor.
5. Use the coaxial sealant to seal each connection between the wireless field
device, lightning arrestor, cable, and antenna.
Note
The remote mount antenna kit includes coaxial sealant for
weatherproofing the cable connections for the lightning arrestor,
antenna, and Rosemount 702 Transmitter. Coaxial sealant must be
applied to guarantee performance of the wireless field network. See
Figure 2‐4 for details on how to apply coaxial sealant.

Applying Coaxial Sealant to Cable ConnectionsFigure 2-4:
6. Ensure the mounting mast and lightning arrestor are grounded according
to local/national electrical code.
Any spare lengths of coaxial cable should be placed in 12-in. (0.3 m) coils.

3 Device network configuration
In order to communicate with the Smart Wireless Gateway, and ultimately
the host system, the transmitter must be configured to communicate with
the wireless network. This step is the wireless equivalent of connecting wires
from a transmitter to the information system. Using a Field Communicator or
AMS Wireless Configurator, enter the Network ID and Join Key so they match
the Network ID and Join Key of the Gateway and other devices in the
network. If the Network ID and Join Key do not match that of the Gateway,
the Rosemount 702 Transmitter will not communicate with the network. The
Network ID and Join Key may be obtained from the Smart Wireless Gateway
on the Setup Network Settings page on the web interface, shown in
Figure 3‐1.
Gateway Network SettingsFigure 3-1:
3.1 AMS Wireless Configurator
1. Right click on the Rosemount 702 Transmitter.
2. Select Configure.
3. When the menu opens, select Join Device to Network.
4. Follow the method to enter the Network ID and Join Key.

4 Verify operation
There are four ways to verify operation: using the optional local display (LCD),
using the Field Communicator, using the Smart Wireless Gateway’s
integrated web interface, or by using AMS Suite Wireless Configurator. If the
Rosemount 702 Transmitter was configured with the Network ID and Join
Key, and sufficient time has passed, the transmitter will be connected to the
network.
4.1 Local display
4.1.1 Start-up sequence
When the Rosemount 702 Transmitter is first powered up, the LCD display
will display a sequence of screens: All Segments On, Device Identification,
Device Tag, and then the user chosen variables of the periodic display.
During steady state operation, the LCD display gives a periodic display of user
chosen variables at the configured wireless update rate. These variables can
be selected from a list of six:
•Channel 1 State
•Channel 1 Count
•Channel 2 State
•Channel 2 Count
•Electronics Temperature
•Supply Voltage
Refer to the Rosemount 702 Reference Manual for error codes and other LCD
display messages. The chevron-shaped status bar at the top of the screen
indicates the progress of the network join process. When the status bar is
filled, the device is successfully connected to the wireless network.

In the Gateway’s integrated web server, navigate to the Explorer page. This
page shows whether the device has joined the network and is
communicating properly.
Note
It may take several minutes for the device to join the network.
Note
If the device joins the network and immediately has an alarm present, it is
likely caused by the sensor configuration. Check the sensor wiring (see
Figure 5‐1) and the sensor configuration (see Table 5‐6).

4.5 Troubleshooting
If the device is not joined to the network after power up, verify the correct
configuration of the Network ID and Join Key, and that Active Advertising has
been enabled on the Smart Wireless Gateway. The Network ID and Join Key in
the device must match the Network ID and Join Key of the Gateway.
Procedure
1. From the Gateway's integrated web interface, select Setup Network
Settings to obtain the Network ID and Join Key (see Figure 4‐3).
