Transmitter Configuration and Use: Series 1000 and 2000 Transmitters 25
Connecting with the 275 HART Communicator or 375 Field Communicator continued
Using the Display Using the CommunicatorUsing ProLink IIBefore You Begin
Note: This procedure allows you to use the device description for the Model 2700 transmitter with the
configurable input/outputs option board. You will not be able to configure the RS-485 parameters
using this device description. To configure the RS-485 parameteres, use the 375 Field Communicator
or ProLink II.
4.3 Connecting to a transmitter
You can connect the Communicator directly to the transmitter’s mA/HART
terminals or to a point on a HART network.
Note: If you are using the mA/HART terminals to report a process variable and also
for HART communication, see the transmitter installation manual for wiring
diagrams.
4.3.1 Connecting to communication terminals
To connect the Communicator directly to the transmitter’s mA/HART terminals:
1. If you are connecting to a Model 1700/2700 transmitter, open the cover to the wiring
compartment.
CAUTION
Connecting a HART device to the transmitter’s
primary mA output terminals could cause transmitter
output error.
If the primary mA output is being used for flow control,
connecting a HART interface to the output loop could
cause the transmitter’s 4–20 mA output to change, which
would affect flow control devices.
Set control devices for manual operation before
connecting a HART interface to the transmitter’s primary
mA output loop.
WARNING
Opening the wiring compartment in a hazardous area
can cause an explosion.
Because the wiring compartment must be open to make
this connection, connections to the mA terminals should
be used only for temporary connections, for example, for
configuration or troubleshooting purposes.
When the transmitter is in an explosive atmosphere, use a
different method to connect to your transmitter.
