The unit was shipped to you without the battery installed. Please remove the battery pack
from the unit prior to shipping.
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. Please consult current regulations
and requirements before shipping.
The battery pack 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.
Batteries should be stored in a clean and dry area. For maximum battery life,
storage temperature should not exceed 30° C.

Rosemount 702
CONSIDERATIONS
GeneralSwitches produce either an open or closed signal. With simple HART
configuration the Rosemount 702 converts the switch signal to a
wireless-enabled signal.l.
CommissioningThe transmitter can be commissioned before or after installation. It may be
useful to commission it on the bench, before installation, to ensure proper
operation and to become familiar with its functionality. When applicable, make
sure the instruments are installed in accordance with intrinsically safe or
non-incendive field wiring practices. The device will be powered whenever the
battery is installed. To avoid depleting the battery, make sure it is removed
when the device is not in use.
MechanicalLocation
When choosing an installation location and position, take into account the
need for access to the transmitter. For best performance, the antenna should
be vertical with some space between objects in a parallel metal plane such as
a pipe or metal framework, as the pipes or framework may adversely affect
the performance of the antenna.
Electrical Battery
The Rosemount 702 Wireless Temperature transmitter is battery powered.
The battery pack with the wireless unit contains 2 “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 battery pack 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 battery pack. The battery pack may be
damaged if dropped from heights in excess of 20 feet.
Switch
Make switch connections through the cable entry in the side of the connection
head. Be sure to provide adequate clearance for cover removal.
EnvironmentalVerify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
Temperature Effects
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 the use of
additional thermowell and extension, or remote mounting the transmitter to
thermally isolate it from the process.

Figure 1-1 provides an example of the relationship between transmitter
housing temperature rise and thermowell extension length.
Example
The transmitter specification limit is 85 °C. If the ambient temperature is 55 °C
and the max process temperature to be measured is 815 °C, the maximum
permissible connection head temperature rise is the transmitter specification
limit minus the ambient temperature (moves 85 to 55 °C), or 30 °C.
In this case, an extension of 5” meets this requirement, but 6” provides an
additional margin of thermowell protection, thereby reducing risk of ambient
thermal damage.

Switch ConnectionsThe 702 is compatible with a number of simple switches. Figure 2-1 shows
the correct input connections to the switch terminals on the transmitter. To
ensure a proper switch connection, anchor the switch lead wires into the
appropriate compression terminals and tighten the screws.
Switch Leads
If the switch is installed in a high-voltage environment and a fault condition or
installation error occurs, the sensor leads and transmitter terminals could
carry lethal voltages. Use extreme caution when making contact with the
leads and terminals.
Use the following steps to wire the sensor and supply power to the
transmitter:
1.Remove the transmitter enclosure cover (if applicable).
2.Attach the sensor leads according to the wiring diagrams
3.Connect the battery.
4.Verify the connection by observing the LCD
5.Reattach and tighten the cover (if applicable).
DEVICE SENSOR
CONFIGURATION
DEVICE NETWORK
CONFIGURATION
Begin by removing the battery-side housing cover. This will expose the
terminal block and HART communication terminals. Connect the battery to
supply power for configuration.
The Rosemount 702 will receive any HART communications from a handheld
Field Communicator, or AMS. When using a Field Communicator, any
configuration changes must be sent to the transmitter by using the Send key
(F2). AMS configuration changes are implemented when the Apply button is
clicked.
AMS Wireless and Direct Connections
AMS is capable of connecting to devices either directly, using a HART
modem, or through wireless via the 1420. When configuring on the bench
using a HART modem, double click the device icon (or right click and select
Configure/Setup), then choose the Configure/Setup tab. Configure the device
settings using the Direct Connection menu. When configuring wirelessly via
the 1420, double click the device icon (or right click and select
Configure/Setup), then choose the Configure/Setup tab. Configure the device
settings using the Wireless Connection menu.
In order to communicate with the 1420 Wireless Gateway, and ultimately the
Information 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, enter the Network ID and Join Key so
that they match the Network ID and Join Key of the gateway and other
devices in the network. If the Network ID and Join Key are not identical, the
transmitter will not communicate with the network. The Network ID and Join
Key may be obtained from the 1420 Wireless Gateway on the
Setup>Network>Settings page on the web server.

The final device network configuration piece is the Update Rate. This by
default is 5 minutes. This may be changed at commissioning, or at any time
via AMS or the 1420 Wireless Gateway’s web server. The Update Rate
should be between 15 seconds and 60 minutes. For networks of up to 100
wireless devices, fastest Update Rate is 60 seconds. For networks of 50 or
fewer devices, the fastest Update Rate is 15 seconds
When device configuration is completed, remove the battery and replace the
battery cover. Tighten the cover to the proper tension for safety approvals.

MOUNTINGThe Rosemount 702 can be installed in one of two configurations: Direct
Mount, where the switch is connected directly to the 702 housing’s conduit
entry, or Remote Mount, where the switch is mounted separate from the 702
housing, then connected to the 702 via conduit. Choose the installation
sequence that corresponds to the mounting configuration.
Figure 3-1 provides an example of the relationship between transmitter
housing temperature rise and extension length.
Figure 3-1. 702 Transmitter
Connection Head Temperature
Rise vs. Extension Length
Example
The transmitter specification limit is 85 °C. If the ambient temperature is 55 °C
and the max process temperature to be measured is 815 °C, the maximum
permissible connection head temperature rise is the transmitter specification
limit minus the ambient temperature (moves 85 to 55 °C), or 30 °C.
In this case, an extension of 5” meets this requirement, but 6” provides an
additional margin of thermowell protection, thereby reducing risk of ambient
thermal damage.
Direct MountThe direct mount installation should not be used when installing with a

Ground the TransmitterThe transmitter will operate with the housing either floating or grounded.
However, the extra noise in floating systems affects many types of readout
devices. If the signal appears noisy or erratic, grounding the transmitter at a
single point may solve the problem.
The electronics enclosure should be grounded in accordance with local and
national installation codes. This can be accomplished via the process
connection, via the internal case grounding terminal, or via the external
grounding terminal.
Switch Inputs
Each process installation has different requirements for grounding. Use the
grounding options recommended by the facility for the specific switch type, or
