Rotating The Lcd Display; Setting Units - Emerson Rosemount 3051S Series Reference Manual

The most effective transmitter case grounding method is a direct connection to earth ground with
minimal (< 1 ) impedance.
Note
Grounding the transmitter case using the threaded conduit connection may not provide a sufficient
ground. The transient protection terminal block (Option Code T1) will not provide transient protection
unless the transmitter case is properly grounded. Use the above guidelines to ground the transmitter
case. Do not run transient protection ground wire with signal wiring; the ground wire may carry
excessive current if a lightning strike occurs.

Rotating the LCD display

Transmitters ordered with the LCD display will be shipped with the display installed. The display can be
rotated in 90 degree increments. To rotate the display:
1. Ensure the power is removed from the transmitter.
2. Remove the cover to expose the LCD display.
3. Squeeze the two tabs that hold the meter in and gently pull.
4. Ensure the four-pin connector is still in the transmitter circuit board. If the connector stayed in the
meter, remove it from the meter and insert it into the transmitter circuit board.
5. Get the LCD display in the orientation desired, squeeze the two tabs to remove the meter and gently
insert the meter in to the electronics circuit board. If the meter does not insert correctly, check the
alignment of the four-pin connector and try again.
6. Install the meter cover and tighten to ensure metal-to-metal contact.
