INSTALLATION
Hart board hardware for installation
to an IZMSG flowmeter
Qty: 4 – M3 x 10mm standoffs
(Included in kit)
1.) Remove the X9 terminal block from the Junction board indicated
to the right.
2.) Remove the 4 indicated screws holding the Junction board to the
Main circuit board (see manual AIC2040 page 1-5, Figure 1-5).
3.) Place the screws and washers to the side for reuse when
installing the Hart board.
4.) Install M3 x 10mm standoffs to the 4 Hart mount location
indicated on the Junction circuit board positions indicated
to the right.
5.) Fasten the Hart board to the Junction board using the screws
removed in step 2.
6.) Connect prewired CS3-BUS connector to corresponding X9
socket located on the Junction board.

Transmitter Board
Secure ground
wire to 300-SMB1
upper left mount
with screw.
Zero Trim
1.) Apply loop power to the Hart transmitter board after
applying power to the IZMSG converter.
2.) Connect the Hart communication device across the
transmitter terminals. The signal loop must have at least
250 ohms resistance for Hart communication device function.
3.) Turn on the Hart communication device. Wait until
communications are established and the Home Menu is
displayed.
4.) If the Process Value is not within specification after
stabilization:
1. Select Calibration
2. Select D/A trim
3. Select “OK” to acknowledge WARN-LOOP remove from
auto control
4. Select “OK” to acknowledge connection of mA indicator
5. Select “OK” to acknowledge setting field deviation
output to 4mA.
6. Enter indicated mA value and acknowledge with
selecting “OK”
7. Acknowledge indicated mA adjustment with “YES/NO”
then select “OK”
8. Select “OK” to acknowledge setting field deviation
output to 20mA.
9. Enter indicated mA value and acknowledge with selecting “OK”
10. Acknowledge indicated mA adjustment with “YES/NO” then
select “OK
11. Select “OK” to acknowledge loop returning to original output
12. Select “OK” to acknowledge NOTE return to auto control
NOTE: Hart output will fault at 3.85mA with loss of IZMSG
signal.
NOTE: Disconnecting the CS-3 terminal while
operating the flowmeter will cause temporary
lose of measurement.
