Grounding

Rosemount 3051S Wireless Series
Whenever you remove flanges or adapters, visually inspect the Teflon
O-rings. Replace them if there are any signs of damage, such as nicks or
cuts. If you replace the O-rings, re-torque the flange bolts after installation to
compensate for cold flow. Refer to the process sensor body reassembly
procedure in Section 6: Troubleshooting on page 6-5.
The housing can be rotated to improve field access to wiring or to better view
the optional LCD display. Perform the following procedure:
Wireless PlantWeb Housing
1. Loosen the housing rotation set screw.
2. First rotate the housing clockwise to the desired location. If the desired
location cannot be achieved due to thread limit, rotate the housing
counter clockwise to the desired location (up to 360° from thread limit).
3. Retighten the housing rotation set screw.
In addition to housing rotation, the optional LCD display can be rotated in
90-degree increments by squeezing the two tabs, pulling out, rotating and
snapping back into place.
NOTE
If LCD pins are inadvertently removed from the interface board, carefully
re-insert the pins before snapping the LCD display back into place.
Transmitter Case
Always ground the transmitter case in accordance with national and local
electrical codes. The most effective transmitter case grounding method is a
direct connection to earth ground with minimal impedance. Methods for
grounding the transmitter case include:
• External Ground Assembly: The External Ground Assembly can also
be ordered with the transmitter (Option Code D4), or as a spare part
(03151-9060-0001).
