STEP 2: CONSIDER HOUSING ROTATION

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.
