Quick start with the Field Communicator
You can connect the Field Communicator to the HART clips on the transmitter, to any point in a local
HART loop, or to any point in a HART multidrop network.
If the transmitter is in a hazardous area, do not remove the housing cover while power is
being supplied to the unit. Removing the housing cover while power is supplied to the unit
could cause an explosion. To access transmitter information in a hazardous environment,
use a communication method that does not require removing the transmitter housing cover.
Important
If the HART security switch is set to
ON
, HART protocol cannot be used to perform any action that
requires writing to the transmitter. For example, you cannot change the configuration, reset totalizers,
or perform calibration using the Field Communicator or ProLink II with a HART connection. When the
HART security switch is set to
OFF
, no functions are disabled.
Procedure
1.
To connect to the HART clips:
a.
Remove the transmitter housing cover.
b.
Attach the leads from the Field Communicator to the HART clips on the face of the transmitter
and add resistance as necessary.
The Field Communicator must be connected across a resistance of 250–600 Ω.
Tip
HART connections are polarity-insensitive. It does not matter which lead you attach to which
terminal.
