To improve field access or to better view the optional LCD display:
1. Loosen the housing lock nut.
2. Rotate the housing clockwise to the desired position – up to 90° from its original position.
Over rotating will damage the transmitter.
3. If the desired position is attained, tighten the housing lock nut.
4. If the desired position cannot be reached because the housing will not rotate further,
rotate the housing counterclockwise until in the desired position (up to 90° from its
original position).
5. Tighten the housing lock nut to 420-in/lb. Use a sealing compound
(Loctite 222 – Small Screw Threadlocker) on the threads to ensure a watertight seal on
the housing.
NOTE
If the desired position cannot be attained within the 90° limit, the transmitter will need to be
disassembled. See the Rosemount 1151 reference manual (document number
00809-0100-4360) for further instruction.
