Assembly Options
(Option Code X1, X2,
and X3)
Option Code X1, X2, or X3 specifies that the transmitter will be
assembled to a sensor. The same option code must be included on the
Rosemount sensor model number. These options are only available with
the transmitter when ordered in conjunction with an integral
connection head.
Assembly descriptions for each option code:
NOTE
X1 and X3 are not available with CSA Approvals Option (Codes C6
and I6).
External Ground Lug
Assembly
(Option Code G1)
The external ground-lug assembly provides an auxiliary grounding
point for the transmitter housing. The lug attaches to either side of the
housing. Refer to Figure 6-1.

3144/3244MV Transmitter.
50 Hz Line Voltage Filter
(Option Code F5)
Option Code F5 specifies that the transmitter be calibrated to a 50 Hz
line voltage filter instead of the standard 60 Hz. Option Code F5 is
recommended for transmitters in Europe and other areas where
50 Hz ac power is standard. Use the Model 275 HART Communicator to
change the line voltage filter after the transmitter is installed (see
“50/60 Hz Filter” on page 3-6).
NAMUR Compliant
Operation
(Option Codes A1 and CN)
Option Codes A1 and CN specify that the transmitter linear output and
alarm levels be pre-set at the factory to comply with NAMUR
standards. Option Code CN is set to low alarm. For more information on
the A1 and CN options, refer to “Failure Mode” on page 5-5.
