The Rosemount 702 Transmitter and all other wireless devices should be installed only after the
Emerson Wireless Gateway has been installed and is functioning properly. Wireless devices should also
be powered up in order of proximity from the Gateway, beginning with the closest. This will result in a
simpler and faster network installation.
Shipping considerations for wireless products.
The unit was shipped to you without the power module installed. Remove the power module prior to
shipping.
Each power module contains two “C” size primary lithium batteries. Primary lithium batteries are
regulated in transportation by the U. S. Department of Transportation, and are also covered by IATA
(International Air Transport Association), ICAO (International Civil Aviation Organization), and ARD
(European Ground Transportation of Dangerous Goods). It is the responsibility of the shipper to ensure
compliance with these or any other local requirements. Consult current regulations and requirements
before shipping.
The power module with the wireless unit contains two “C” size primary lithium/thionyl chloride
batteries. Each battery contains approximately 2.5 grams of lithium, for a total of 5 grams in each pack.
Under normal conditions, the battery materials are self-contained and are not reactive as long as the
batteries and the pack integrity are maintained. Care should be taken to prevent thermal, electrical, or
mechanical damage. Contacts should be protected to prevent premature discharge.
Battery hazards remain when cells are discharged.
Power modules should be stored in a clean and dry area. For maximum battery life, storage
temperature should not exceed 30 °C.
The power module has surface resistivity greater than one gigaohm and must be properly installed in
the wireless device enclosure. Care must be taken during transportation to and from the point of
installation to prevent electrostatic charge build-up.

1.3.2 Wireless considerations
Power up sequence
The Emerson™ Wireless Gateway should be installed and functioning properly before any wireless field
devices are powered. Install the Black Power Module, SmartPower
(part number 00753-9220-0001) into the Rosemount 702 Transmitter to power the device. Wireless
devices should also be powered up in order of proximity from the Gateway, beginning with the closest.
This will result in a simpler and faster network installation. Enable Active Advertising on the Gateway to
ensure that new devices join the network faster. For more information see the Emerson Wireless
Gateway Reference Manual
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.

Connecting the Field Communicator to the power module
The power module needs to be connected for the Field Communicator to interface with the transmitter.
Figure 1-3. Field Communicator Connections
1.3.3 Choosing an installation location and position
When choosing an installation location and position, take into account access to the Rosemount 702
Transmitter. For best performance, the antenna should be vertical with space between objects in a
parallel metal plane, such as a pipe or metal framework, as the pipes or framework may adversely affect
the antenna’s performance.

1.3.4 Electrical
Caring for the power module
The Rosemount 702 Transmitter is self-powered. The included Black Power Module contains two “C” size
primary lithium/thionyl chloride batteries. Each battery contains approximately 2.5 grams of lithium, for
a total of 5 grams in each pack. Under normal conditions, the battery materials are self-contained and
are not reactive as long as the batteries and the power module are maintained. Care should be taken to
prevent thermal, electrical, or mechanical damage. Contacts should be protected to prevent premature
discharge.
Use caution when handling the power module, it may be damaged if dropped from heights in excess of
20 ft. (6,10 m).
Making switch connections
Make switch connections through the cable entry in the side of the connection head. Be sure to provide
adequate clearance for cover removal.
1.3.5 Verifying operating atmosphere
Introduction
June 2018
Verify that the operating atmosphere of the transmitter is consistent with the appropriate hazardous
locations certifications.
Isolating the transmitter from sources of heat
The transmitter will operate within specifications for ambient temperatures between –40 and 185 °F
(–40 and 85 °C). Heat from the process is transferred from the switch to the transmitter housing. If the
expected process temperature is near or beyond specification limits, consider using an extension, or
remote mount the transmitter to thermally isolate it from the process.
Figure 1-4 provides an example of the relationship between the transmitter housing temperature rise
and the extension length.

Example
The transmitter specification limit is 185 °F (85 °C). If the ambient temperature is 131 °F (55 °C) and the
maximum process temperature to be measured is 1500 °F(815 °C), the maximum permissible
connection head temperature rise is the transmitter specification limit minus the ambient temperature
(moves 185 °F to 131 °F [85 to 55 °C]), or 86 °F (30 °C).
In this case, an extension of 5-in. (0.13 m) meets t his requirement, but 6-in. (0.15 m) provides an
additional margin of protection, thereby reducing risk of ambient thermal damage.

The Rosemount ™ 702 Wireless Discrete Transmitter can be installed in one of two configurations:
Direct mount: The switch is connected directly to the transmitter housing’s conduit entry. For
installation instructions see “Direct mount configuration” on page 16.
Remote mount: The switch is mounted separate from the transmitter housing, then connected to the
transmitter via conduit. For installation instructions see “Remote mount configuration” on page 18. Use
Remote mount instructions for the installation of liquid hydrocarbon sensors.
3.2.1 Direct mount configuration
1. Install the switch according to standard installation practices making sure to use thread sealant on all
of the connections.
2. Attach the Rosemount 702 Transmitter housing to the switch by using the pipe fittings threaded into
the conduit entries.

Note
Wireless devices should only be powered up after the Emerson
™
Wireless Gateway, in order of proximity
from the Gateway beginning with the closest device. This results in a simpler and faster network
installation.

5. Close the housing cover and tighten to safety specifications. Always ensure a proper seal by installing
the electronic housing covers so that metal touches metal, but do not overtighten.
6. Position the antenna such that it is vertical, either straight up or straight down, as shown in
Figure 3-3. The antenna should be approximately 3 ft. (1 m) from any large structures or buildings, to
allow clear communication to other devices.

3.3.2 Wireless output specifications
Dual input
The Rosemount 702 Transmitter will accept the input from one or two single pole single throw switches
on inputs S1 and S2. The wireless output of the transmitter will be both a primary variable (PV) and a
secondary variable (SV). The PV is determined by the S1 input. The SV is determined by the S2 input. A
closed switch drives a TRUE output. An open switch drives a FALSE output.

Dual input, limit contact logic
When configured for Limit contact logic, the Rosemount 702 Transmitter will accept the input from two
single pole single throw switches on inputs S1 and S2, and will use limit contact logic for the
determination of the wireless outputs. Reference Figure 3-7 for details on the wireless outputs available
when using limit contact logic.

Dual input, opposing contact logic
When configured for opposing contact logic, the Rosemount 702 Transmitter will accept the input from
a single pole double throw switch on inputs S1 and S2, and will use opposing contact logic for the
determination of the wireless outputs. Reference Figure 3-8 for details on the wireless outputs available
when using opposing contact logic.

The liquid hydrocarbon detection configuration is intended for use with the Tyco® Tra ceTek® Fast Fuel
Sensor, or TraceTek Sensing cable.
Figure 3-10. Fuel Sensor Connection
Connecting to the fast fuel sensor and TraceTek sensing cable
The connections to the Fast Fuel Sensor TraceTek Sensing cable are made by matching the appropriately
colored wires to the matching colored termination lugs.
The Rosemount 702 Transmitter can support up to three Tyco Fast Fuel Sensors. These sensors are
connected using TraceTek Modular Leader Cable (TT-MLC-MC-BLK), optional modular jumper cables
(TT-MJC-xx-MC-BLK) and branching connectors (TT-ZBC-MC-BLK) as suggested in Figure 3-11.
If more than one sensor is attached to a transmitter, the detection of liquid hydrocarbon by one sensor
is sufficient to cause the transmitter to send a “Leak” message. However, it is not possible for the
transmitter to discern which individual sensor has detected liquid hydrocarbon.
