COMMISSIONING
In the event of certain IPX II Series Smart Pressure Transmitter failure modes, the lower portion of the
display changes to either S
S S S S F F F F FA A A A AUL UL UL UL ULT TT TT or X X X X X F F F F FA A A A AUL UL UL UL ULT TT TT.
This LCD display takes full advantage of the precision of the IPX II Series Smart Pressure Transmitter.
The digital display of the measurement does not include the small D/A error present in the analog
output. It provides highly accurate local indication of the measurement, local fault diagnostics, and
the IPX II Series Smart Pressure Transmitter identification. The LCD continues to display the measured
variable even if it is beyond the zero and span limits set for the analog output. The value of this
display as a set-up, calibration and reconfiguration tool may even be greater.

If the optional dual LCD display is ordered, configuration of an IPX II Series Pressure Transmitter is
possible. This inexpensive option makes reconfiguration or re-ranging of the transmitter simple and
easy.
In the event that the dual LCD display is not purchased at the same time as the transmitter, one must
follow the field installation instructions supplied with the display very carefully to avoid damage to
the transmitter or the display, itself.
