Operation with the HART protocol
Besides local operation, the Promag 33 flowmeter can also be configured and
measured values called up using the HART protocol. Two procedures can be used:
•
Operation using the “HART Communicator DXR 275” universal handheld terminal.
•
Operation using a personal computer with specific software, e.g. “Commuwin II”,
and the “Commubox FXA 191” HART modem.
Operating using the “HART Communicator DXR 275”
Promag 33 functions are selected with the HART communicator over a number of
menu levels as well as with the aid of a special E+H operating matrix (see Fig. 40).
Notes!
•
The HART protocol requires a “4–20 mA” setting of the current output (see page
51). The “4–20 mA” setting is only selectable if the setting “HART” is switched off in
the function “PROTOCOL” (see page 69).
•
All functions are accessible at all times with the HART handheld terminal i.e.
programming is not locked. The HART operating matrix can, however, be locked by
entering the value “–1” in the function “ACCESS CODE”. Data can then no longer
be changed. This status remains even after a power failure. The operating matrix
can again be enabled by entering the personal code number.
•
Further information on the HART Communicator is given in the appropriate
operating manual in the carrying case.

Procedure
1. Switch on handheld terminal:
a. The transmitter is not yet connected
→
The HART main menu is displayed
→
Continue with
“Online”
b. The transmitter is already connected
→
The menu level “Online” is immediately shown.
2. “Online” menu level:
→
Actual measurement data including flow, totaliser sum, etc. are continually shown.
→
Via “Matrix group sel.” you have access to the HART operating matrix (see Fig. 40),
then to the function group (e.g. current output) and finally to the desired function,
e.g. “Damping PV”.
3. Enter values or change the setting.
4. The field “SEND” is shown by pressing the “F2” function key. By pressing the “F2” key,
all values and settings entered with the handheld terminal are registered by the Promag
measuring system. Confirm with the “F4” key.
5. Press “F3” HOME function key to return to the “Online” menu level. The actual values measured
by the Promag flowmeter with the new settings can now be read off.
