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.
