To expedite the return process outside of the United States, contact the nearest Emerson
Process Management representative.
Within the United States, call the Emerson Process Management Instrument and Valve
Response Center using the 1-800-654-RSMT (7768) toll-free number. This center, available
24 hours a day, will assist you with any needed information or materials.
The center will ask for product model and serial numbers, and will provide a Return Material
Authorization (RMA) number. The center will also ask for the process material to which the
product was last exposed.
Individuals who handle products exposed to a hazardous substance can avoid injury if they
are informed of and understand the hazard. The product being returned will require a copy
of the required Material Safety Data Sheet (MSDS) for each substance must be included
with the returned goods.
Emerson Process Management Instrument and Valve Response Center representatives will
explain the additional information and procedures necessary to return goods exposed to
hazardous substances.
6.4 Diagnostics identification and recommended
action
The Rosemount 2051 PROFIBUS device diagnostics can be used to warn a user about a
potential transmitter error. There is a transmitter error if the Output Status reads anything
but Good or Good - Function Check, or the LCD display reads SNSR or ELECT. Use
identify what diagnostic condition exists based on the combination of errors under the How
to Identify columns. Start with the Physical block diagnostic extension and use Primary value
and Temperature status to identify the diagnostic condition. If a box is blank, it is not
necessary to identify that diagnostic condition. Once condition is identified, use the What to
do column to remedy the error.
