NOTICE
This guide provides basic guidelines for the Rosemount 248 Wireless. It does not provide
instructions for detailed configuration, diagnostics, maintenance, service, troubleshooting, or
installations. Refer to the Rosemount 248 Wireless Reference Manual (document number
00809-0100-4248) for more instruction. The manual and this guide are also available
electronically on www.rosemount.com.
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.
Before connecting a Field Communicator in an explosive atmosphere, make sure the
instruments are installed in accordance with intrinsically safe or non-incendive field wiring
practices.
Verify the operating atmosphere of the transmitter is consistent with the appropriate
hazardous locations certifications.
Process leaks could result in death or serious injury.
Do not remove the thermowell while in operation.
Install and tighten thermowells and sensors before applying pressure.
Electrical shock could cause death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be present on leads can
cause electrical shock.

NOTICE
Power Module Considerations (Green Power Module, model number 701PGNKF):
The Green Power Module with the wireless unit contains one “D” size primary lithium-thionyl
chloride battery (model number 701PGNKF). Each battery contains approximately 5.0 grams
of lithium. 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 Power Module life,
storage temperature should not exceed 30 °C.
Power Module Considerations (Black Power Module, model number 701PBKKF):
The Green Power Module with the wireless unit contains two “C” size primary lithium-thionyl
chloride battery (model number 701PGNKF). 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 Power Module life,
storage temperature should not exceed 30 °C.

Wireless considerations
Power up sequence
The Power Module should not be installed on any wireless device until the Smart
Wireless Gateway is installed and functioning properly. Wireless devices should
also be powered up in order of proximity from the Smart Wireless Gateway,
beginning with the closest. This will result in a simpler and faster network
installation. Enable Active Advertising on the Gateway to ensure new devices join
the network faster. For more information, see the Smart Wireless Gateway
Manual (document number 00809-0200-4420).
Antenna position
Polymer housing (enclosure option code P)
The internal antenna is designed for multiple mounting orientations. The
transmitter should be mounted according to best practices for your temperature
measurement application. The transmitter should be approximately 3 ft (1 m)
from any large structure or building to allow clear communication to other
devices.
Aluminum housing (enclosure option code D)
The external antenna should be positioned vertically, either straight up or straight
down. The transmitter should be mounted according to best practices for your
temperature measurement application. The transmitter should be approximately
3 ft (1 m) from any large structure or building to allow clear communication to
other devices.

Field Communicator connections
Polymer housing
The Power Module must be installed in the device for the Field Communicator to
interface with the Rosemount 248 Wireless Temperature Transmitter. The Field
Communicator connections are located on the Green Power Module. To
communicate to the transmitter, begin by removing the power module cover.
This will expose the HART communication terminals located on the Green Power
Module. Next, connect the Field Communicator leads to the COMM port
connections on the Green Power Module.
This transmitter uses the Green Power Module; please order model number
701PGNKF. The Power Module is keyed and can only be inserted in one
orientation. Field communication with this device requires a HART-based Field
Communicator. Refer to Figure 3 for instructions on connecting the Field
Communicator to the Rosemount 248 Wireless.

Step 2: Verify operation
Polymer housing
Operations can be verified in four locations: at the device via the Local Display,
using the Field Communicator, at the Smart Wireless Gateway's integrated web
interface, or using AMS®Suite Wireless Configurator or AMS Device Manager.
Local display
During normal operation, the LCD display will display the PV value at the
configured update rate.
For Device Status screens, see LCD screen messages on Rosemount 248 Wireless
Reference Manual (document number 00809-0100-4248).
Aluminum housing
Operations can be verified in three locations: using the Field Communicator, at
the Smart Wireless Gateway's integrated web interface, or using AMS Suite
Wireless Configurator or AMS Device Manager.
Field Communicator
For HART Wireless transmitter communication, a Rosemount 248 Wireless DD is
required. To obtain the latest DD, visit the Emerson Process Management Easy
Upgrade site at:
http://www2.emersonprocess.com/en-us/documentation/deviceinstallkits/page

Emerson Smart Wireless Gateway
In the integrated web interface from the Gateway, navigate to the
Explorer>Status page. This page shows whether the device has joined the
network and if it 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 due to sensor
configuration. Check the sensor wiring (see Figure 15 on page 17) and the sensor configuration
(see Table 5 on page 19).

AMS Wireless Configurator
When the device has joined the network, it will appear in the Wireless
Configurator window as illustrated in figure below. For HART Wireless transmitter
communication, a Rosemount 248 Wireless DD is required. To obtain the latest
DD, visit the Emerson Process Management Easy Upgrade site at:

Troubleshooting
If the device is not joining to the network, check to make sure that you have a
power supply in your device. If the device is not joined to the network after power
up, verify the correct configuration of the Network ID and Join Key, and verify 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.
The Network ID and Join Key may be obtained from the Gateway on the
Setup>Network>Settings page on the web server (see Figure 13 on page 15).
The Network ID and Join Key may be changed in the wireless device by using the
following Fast Key sequence.
