Rosemount 848T Wireless

IMPORTANT NOTICE

This installation guide provides basic guidelines for the Rosemount 848T. It does not

provide instructions for detailed configuration, diagnostics, maintenance, service,

troubleshooting, or installations. Refer to the Rosemount 848T reference manual

(Document Number 00809-0100-4848) for more instruction. The manual and this QIG are

also available electronically on www.rosemount.com.

WARNING

Explosions could result in death or serious injury:

Installation of this transmitter in an explosive environment must be in accordance with the

appropriate local, national, and international standards, codes, and practices. Please

review the Product Certifications section for any restrictions associated with a safe

installation.

• Before connecting a Rosemount 375 Field Communicator in an explosive

atmosphere, ensure the instruments are installed in accordance with intrinsically safe

or non-incendive field wiring practices. Electrical shock can result in death or serious

injury

• Avoid contact with the leads and terminals. High voltage that may be present on leads

can cause electrical shock. This device complies with Part 15 of the FCC Rules.

Operation is subject to the following conditions. This device may not cause harmful

interference. This device must accept any interference received, including

interference that may cause undesired operation. This device must be installed to

ensure a minimum antenna separation distance of 20 cm from all persons.

• The power module may be replaced in a hazardous area. 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.

IMPORTANT NOTICE

Shipping considerations for wireless products:

The unit was shipped to you without the power module installed. Please remove the

power module prior to shipping the unit.

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. Please consult current regulations and requirements before shipping.

WIRELESS CONSIDERATIONS

Power Up Sequence

The Power Module should not be installed on any wireless device until the Smart Wireless

Gateway (“Gateway”) is installed and 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. Enable Active Advertising on the Gateway

to ensure that new devices join the network faster. For more information see the Smart

Wireless Gateway Manual (Doc. No. 00809-0200-4420).

Antenna Position

The antenna should be positioned vertically 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.

Figure 1.

Conduit Plug

The temporary orange plugs should be replaced with the included conduit plugs using

approved thread sealant.

375 Field Communicator Connections

The Power Module needs to be connected for the 375 Field Communicator to interface with

the 848T Wireless.

STEP 1: PHYSICAL INSTALLATION

Initial Configuration

If the device was ordered with a factory configured Network ID and Join Key, it should join

the network with no user input. If unsure, the Network ID and the Join Key may be manually

entered to match the Gateway’s.

The Network ID and Join Key may be obtained from the Gateway on the

Setup>Network>Settings page on the web server (see Figure below).

The Network ID and Join Key may be changed in the wireless device by using the following

Fast Key sequence.

Sensor Configuration

Sensor inputs can be configured for different sensor types. To verify or change the sensor

configuration with a 375 handheld communicator, use the following Fast Key sequence.

Remote Mount

The Rosemount 848T Wireless can only be installed in the Remote Mount configuration

where the sensor is mounted separate from the 848T housing, then connected to the 848T

via conduit.

1. Install the sensor according to standard installation practices. Be sure to use thread

sealant on all connections.

STEP 1 CONTINUED...

2. To reduce sensor wiring length, mount the Rosemount 848T Wireless transmitter central

to all of the measurements. When installing the 848T wireless, the conduit entries need

to be facing downward. If using the mounting bracket (Option Code B6), mount to a 2-in.

pipe.

3. Run wiring (and conduit, if necessary) from the sensor to the 848T. For an easier

installation, use the outside conduit entries as shown below. Any unused conduit entries

should be sealed with approved sealant using the included threaded conduit plugs.

4. Pull the wiring through the threaded conduit entry of the 848T.

5. Attach the sensor wiring to the terminals as indicated on the wiring diagram. Note that

Terminal screw 5 is for attaching the shield wire of the sensor to the device. See 848T

Wireless Reference Manual (Document No. 00809-0100-4848) for more information.

6. To connect the power module, remove the plastic plug from the receptacle.

7. After initial installation, close the housing cover securely. Always ensure a proper seal by

installing the electronics housing cover so that metal touches metal, but do not over

tighten.

8. Position the antenna vertically. The antenna should be approximately three feet (1 m)

from any large structures or buildings to allow clear communication to other devices.

STEP 2: VERIFY OPERATION

Operation can be verified using one of three methods: 375 Field Communicator, the Smart

Wireless Gateway’s integrated web interface, or via AMS™Wireless Configurator.

375 Field Communicator

For HART communication, a 848T Wireless DD is required. For connecting with a 375 Field

Communicator, refer to Figure 3: Connection Diagram on page 4.

Smart Wireless Gateway

In the Gateway’s integrated web interface, navigate to the Explorer 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 Rosemount 848T Terminal

Diagram on page 9) and the sensor configuration (see 848T Fast Key Sequence for

handheld communicator on page 9).
