Installation
Note
Do not rotate the housing more than 180 degrees without first performing a disassembly
procedure (see “Housing Assembly including Feature Board Electronics” on page 2-16).
Over-rotation may sever the electrical connection between the sensor module and the feature
board.
3. Retighten the housing rotation set screw.
Figure 2-2. Housing
LCD display rotation
In addition to housing rotation, the optional LCD display can be rotated in 90° increments by
squeezing the two tabs, pulling out, rotating and snapping back into place.
Note
If LCD pins are inadvertently removed from the feature board, re-insert the pins before snapping
the LCD display back into place.
Field terminal side of housing
Mount the transmitter so the terminal side is accessible. Clearance of 0.75 in. (19 mm) is
required for cover removal. Use a conduit plug in the unused conduit opening if the optional
Process Temperature Input is not installed.
Feature board side of housing
Provide 0.75-in. (19 mm) of clearance for units without an LCD display. Three inches of clearance
is required for cover removal if an LCD display is installed.
Cover installation
Always ensure a proper seal by installing the housing covers so that metal contacts metal in
order to prevent performance degradation due to environmental effects. For replacement cover
o-rings, use Rosemount o-rings (part number 03151-9040-0001).
Conduit entry threads
For NEMA 4X, IP66, and IP68 requirements, use thread seal (PTFE) tape or paste on male threads
to provide a watertight seal.
