Wiring Diagrams Bench Hook-up

Connect the bench equipment as shown in Figures 3-1 and 3-2, and turn on

the Field Communicator by pressing the ON/OFF key or log into AMS. The

Field Communicator or AMS will search for a HART-compatible device and

indicate when the connection is made. If the Field Communicator or AMS fail

to connect, it indicates that no device was found. If this occurs, refer to

Section 5: Troubleshooting.

Field Hook-up

Figures 3-1 and 3-2 illustrate wiring loops for a field hook-up with a Field

Communicator or AMS. The Field Communicator or AMS may be connected

at “COMM” on the transmitter terminal block, across the load resistor, or at

any termination point in the signal loop. Signal point may be grounded at any

point or left ungrounded.
