Connecting the RTD/PRT

EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-
hazardous. Performing this operation in a hazardous area could result in an explosion.
RTD connections reside on the terminal plate under the rear cover. The flow computer
supports 2-wire, 3-wire, and 4-wire operation for a PT100 RTD. Route the RTD cable
through the conduit fittings and connect them on the terminal plate (as shown on
2-30).
Note
The device defaults to the 4-wire RTD configuration; you can change this setting in
FBxConnect.
