Quick Start Guide
Note
Emerson provides 4-wire sensors for all single element RTDs. Use these RTDs in 3- or 2-wire
configurations by leaving the unneeded leads disconnected and insulated with electrical
tape.
Note
In order to communicate with a Field Communicator, the wireless device must be powered
by connecting the power module.

Single element, 3-wire
Note
To configure a single element, 4-wire RTD as a 3-wire system, connect only one white lead.
Insulate or terminate the unused white lead in a manner that prevents shorting to the
ground.
To configure a single element, 4-wire RTD as a 2-wire system, connect matching colored
wires first and then connect the paired wires to the terminal.
