Quick Start Guide

About this guide

This guide provides basic guidelines for the Rosemount ™ 848T Temperature

Transmitter. It does not provide instructions for detailed configuration, diagnostics, maintenance, service, troubleshooting. Refer to the Rosemount

848T Reference Manual for more instruction. The manual and this guide are also available electronically on Emerson.com/Rosemount

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. Review the approvals section of this manual for any restrictions associated with a safe installation.

• Before connecting a Field Communicator in an explosive atmosphere, make sure the instruments in the loop 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.

Physical access

• Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end users’ equipment. This could be intentional or unintentional and needs to be protected against.

• Physical security is an important part of any security program and fundamental to protecting your system. Restrict physical access by unauthorized personnel to protect end users’ assets. This is true for all systems used within the facility.

CAUTION

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.

Quick Start Guide 3


NOTICE

Battery hazards remain when cells are discharged.

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.

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.

• All sensor and power terminals are rated to 42.4 Vdc.

• F

OUNDATION

Fieldbus network powered with a terminal voltage of 9.0–

32.0 Vdc and 22 mA maximum current draw.

• For best network performance twisted, shielded pair cabling should be used. Proper gage wire should be selected to maintain the 9.0 Vdc minimum.

3-wire configurations by clipping the fourth lead or leaving it disconnected and insulated with electrical tape.

(2) The transmitter must be configured for a 3-wire RTD in order to recognize an

RTD with a compensation loop.

4 Verify the tag

The Rosemount 848T has a removable commissioning tag that contains both the Device ID (the unique code that identifies a particular device in the absence of a device tag) and a space to record the device tag (the operational identification for the device as defined by the Piping and Instrumentation Diagram [P&ID]).

When commissioning more than one device on a

F OUNDATION

™ Fieldbus segment, it can be difficult to identify which device is at a particular location. The removable tag aids in this process by linking the

Device ID to physical location. The installer should note the physical location of the transmitter on both the upper and lower location of the commissioning tag. The bottom portion should be torn off for each device on the segment and used for commissioning the segment in the control system.

Quick Start Guide

Verify the transmitter configuration

Each F OUNDATION

™ Fieldbus host or configuration tool has a different way of displaying and performing configurations. Some use Device Descriptions

(DD) or DD wizards for configuration and to display data consistently across platforms. There is no requirement that a host or configuration tool support these features.

The following is the minimum configuration requirement for a temperature measurement. This guide is designed for systems not using DD wizards. For a complete list of parameters and configuration information refer to the

Rosemount ™ 848T Reference Manual .

Rev 2.12

European Directive Information

A copy of the EU Declaration of Conformity can be found at the end of the

Quick Start Guide. The most recent revision of the EU Declaration of

Conformity can be found at Emerson.com/Rosemount.

Ordinary Location Certification from FM Approvals

As standard, the transmitter has been examined and tested to determine that the design meets the basic electrical, mechanical, and fire protection requirements by FM Approvals, a nationally recognized test laboratory

(NRTL) as accredited by the Federal Occupational Safety and Health

Administration (OSHA).

North America

The US National Electrical Code ™ (NEC) and the Canadian Electrical Code

(CEC) permit the use of Division marked equipment in Zones and Zone marked equipment in Divisions. The markings must be suitable for the area classification, gas, and temperature class. This information is clearly defined in the respective codes.
