5Operation Temperature head transmitter
40 Endress+Hauser
Open the field housing PG cable gland and connect the
screen of the output and sensor connection according to the
figure opposite (s. fig. 4-4)
When using earthed thermocouples, screening of the output
cable (4 ... 20 mA cable) is recommended.
In plants with strong EMC problems screening of all cables
with a low ohm connection to the transmitter housing is
recommended.

5.1 Communication
The temperature head transmitter is set up using the HART
®
protocol. The values
measured can also be read using the HART
®
protocol. In order to do this the user has
two possibilities:
• Operation using a universal hand operating module “HART
®
Communicator DXR
275”.
• Operation using a PC and operating software (e.g. Commuwin II) as well as a HART
®
modem (e.g. “Commubox FXA 191”).
5.1.1 HART
®
Communicator DXR 275
Selection of the unit functions using the “HART
®
-Communicator” is done using various
menu levels as well as with the help of a special HART
®
function matrix (see page 42).

Hint!
• When using the HART
®
hand unit all parameters can be read out, however,
programming is blocked. It is possible to release the HART
®
function matrix by enter-
ing 281 in the LOCK function. This condition remains even after a power failure. The
HART
®
function matrix can be locked again by releasing the personal code number.
• More detailed information to the HART
®
hand operation module can be found in the
respective operating manual in the carrying case.
5.1.2 Commuwin II-operating programme
Commuwin II is a universal programme for remote operation of field and panel-mounted
instrumentation. Application of the Commuwin II operating programme is possible
independent of the type of unit and communication mode (HART
®
or PROFIBUS
®
).
Commuwin II offers the following functions:
• Setting up unit functions
• Visualisation of measured values
• Data security of unit parameters
• Unit diagnostics
• Measurement point documentation

Hint!
More detailed information to Commuwin II can be found in the E+H documentation:
