Connect with the Field Communicator
A connection from the Field Communicator to your transmitter allows you to read process
data, configure the transmitter, and perform maintenance and troubleshooting tasks.
You can connect the Field Communicator to the mA terminals on the transmitter, to any
point in a local HART loop, or to any point in a HART multidrop network.
CAUTION!
If the transmitter is in a hazardous area, do not connect the Field Communicator to the mA
terminals on the transmitter. This connection requires opening the wiring compartment, and
opening the wiring compartment in a hazardous area can cause an explosion.
Prerequisites
The following HART device description (DD) must be installed on the
Field Communicator: .
Procedure
1.
To connect to the transmitter terminals:
a. Remove the cover from the wiring compartment.
b. Attach the leads from the Field Communicator to terminals 1 and 2 on the
transmitter and add resistance as required.
