NOTICE

This guide provides basic guidelines for the Rosemount 848T. It does not provide instructions for detailed configuration, diagnostics, maintenance, service, troubleshooting. Refer to the Rosemount 848T Reference Manual (document number 00809-0100-4697) for more instruction. The manual and this guide are also available electronically on www.rosemount.com.

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.

Process leaks may cause harm or result in death.

 Install and tighten thermowells or sensors before applying pressure.  Do not remove the thermowell while in operation.

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.

Shipping considerations for wireless products:

The unit was shipped to you without the power module installed. 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. Consult current regulations and requirements before shipping.

Sensor wiring and power supply

 Compatible with eight independently configurable channels including

combinations of 2- and 3-wire RTDs, thermocouples, mV, ohm and mA sensors.

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

 FOUNDATION fieldbus network powered with a terminal voltage of 9.0 to 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.

Step 3: Verify the tag

The 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 Foundation 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.

Step 4: Verify the transmitter configuration

Each FOUNDATION 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 (document number 00809-0100-4697).
