Mount The Transmitter - Emerson Rosemount 3144P Quick Start Manual

Quick Start Guide
With a LCD display
1. Set the loop to manual (if applicable) and disconnect the power.
2. Remove the electronics housing cover.
3. Unscrew the LCD display screws and slide the meter straight off.
4. Set the alarm and security switches to the desired position.
5. Reattach the LCD display and electronics housing cover (consider LCD display
orientation – rotate in 90 degree increments).
6. Apply power and set the loop to automatic control.
Step 4: Mount the transmitter
Mount the transmitter at a high point in the conduit run to prevent moisture from
draining into the transmitter housing.
Typical field mount installation
1. Mount the thermowell to the process container wall. Install and tighten
thermowells. Perform a leak check.
2. Attach any necessary unions, couplings, and extension fittings. Seal the fitting
threads with an approved thread sealant, such as silicone or PTFE tape (if
required).
3. Screw the sensor into the thermowell or directly into the process (depending
on installation requirements).
4. Verify all sealing requirements.
5. Attach the transmitter to the thermowell/sensor assembly. Seal all threads
with an approved thread sealant, such as silicone or PTFE tape (if required).
6. Install field wiring conduit into the open transmitter conduit entry (for remote
mounting) and feed wires into the transmitter housing.
7. Pull the field wiring leads into the terminal side of the housing.
8. Attach the sensor leads to the transmitter sensor terminals (the wiring
diagram is located inside the housing cover).
9. Attach and tighten both transmitter covers.
