Typical HART Connection
Since E3 transmitter supports the HART (Highway
Addressable Remote Transducer) communication protocol,
configuration tools, such as a HART 375 handheld com-
municator, can be used to provide a communication link to
the E3 transmitter. When connected to the control loop,
the same system measurement readings shown on the trans-
mitter are shown on the communicator. In addition, the
communicator can be used to configure the transmitter.
The HART communicator may need to be updated to
include the E3 software (Device Description). Contact your
local HART Service Center for additional information.
2.7.1 Connections
A HART communicator can be operated from a remote
location by connecting to a remote junction or by connect-
ing directly to the terminal block in the electronics housing
of the E3 Modulevel transmitter.
HART uses the Bell 202 frequency shift key technique of
high-frequency digital signals. It operates on the 4–20 mA
loop and requires a minimum of 250 Ω load resistance. A
typical connection between a communicator and the
E3 Modulevel transmitter is illustrated.
2.7.2 HART Display Menu
For detailed operating information for the 375 Field
Communicator, refer to the instruction manual provided
with it.
The E3 transmitter online menu tree is shown in the fol-
lowing illustration. Open the menu by pressing the
alphanumeric key 0, Device Setup, to display the second-
level menu.
