Bolting Considerations
If the transmitter installation requires assembly of the process flanges, manifolds, or flange
adapters, follow these assembly guidelines to ensure a tight seal for optimal performance
characteristics of the transmitters. Use only bolts supplied with the transmitter or sold by
Emerson as spare parts. Figure 1 illustrates common transmitter assemblies with the bolt
length required for proper transmitter assembly.
Figure 1. Common Transmitter Assemblies
Bolts are typically carbon steel or stainless steel. Confirm the material by viewing the
markings on the head of the bolt and referencing Figure 2. If bolt material is not shown in
Figure 2, contact the local Emerson Process Management representative for more
information.
Use the following bolt installation procedure:
1. Carbon steel bolts do not require lubrication and the stainless steel bolts are coated with
a lubricant to ease installation. However, no additional lubricant should be applied when
installing either type of bolt.
2. Finger-tighten the bolts.
3. Torque the bolts to the initial torque value using a crossing pattern. See Figure 2 for
initial torque value.
4. Torque the bolts to the final torque value using the same crossing pattern. See Figure 2
for final torque value.
5. Verify that the flange bolts are protruding through the isolator plate before applying
pressure.

Inline Gage Transmitter Orientation
The low side pressure port (atmospheric reference) on the inline gage transmitter is located
in the neck of the transmitter, behind the housing. The vent path is 360° around the
transmitter between the housing and sensor. (See Figure 3.)
Keep the vent path free of any obstruction, including but not limited to paint, dust, and
lubrication by mounting the transmitter so that the process can drain away.
Figure 3. Inline Gage Transmitter
STEP 2: CONSIDER HOUSING ROTATION
STEP 3: SET SWITCHES (OPTION D1)
(
If alarm and security adjustment option is not installed, the transmitter will operate normally
with the default alarm condition alarm high and the security off.
To improve field access to wiring or to better
view the optional LCD display:
1. Loosen the housing rotation set screw.
2. First, using a 5/64-in. hex wrench, 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 180°
from thread limit).
3. Retighten the housing rotation set screw.

STEP 4: CONNECT WIRING AND POWER UP
Connect Wiring and Power Up
Use the following steps to wire the transmitter:
1. Remove the housing cover labeled “Field Terminals.”
2. Connect the positive lead to the “+” terminal, and the negative lead to the “–” terminal.
NOTE
Do not connect the power across the test terminals. Power could damage the test diode in
the test connection. Twisted pairs yield best results; shielded signal wiring is not necessary.
Use 24 AWG or larger wire and do not exceed 5,000 feet (1500 meters).
3. Plug and seal unused conduit connections.
4. If applicable, install wiring with a drip loop. Arrange the drip loop so the bottom is lower
than the conduit connections and the transmitter housing.
5. Replace the housing cover.
The figures below show the wiring connections necessary to power a 3051C/T and enable
communications with a hand-held HART communicator.

Signal Wiring Grounding
Do not run signal wiring in conduit or open trays with power wiring, or near heavy electrical
equipment. Grounding terminations are provided on the outside of the sensor module and
inside the Terminal Compartment. These grounds are used when transient protect terminal
blocks are installed or to fulfill local regulations. See Step 2 below for more information on
how the cable shield should be grounded.
1. Remove the Field Terminals housing cover.
2. Connect the wiring pair and ground as indicated in Figure 6. The cable shield should:
a. Be trimmed close and insulated from touching the transmitter housing.
b. Continuously connect to the termination point.
c. Be connected to a good earth ground at the power supply end.
Figure 6. Wiring
3. Replace the housing cover. It is recommended that the cover be tightened until there is
no gap between the cover and the housing.
4. Plug and seal unused conduit connections.

STEP 6: TRIM THE TRANSMITTER
Transmitters are shipped fully calibrated per request or by the factory default of full scale
(lower range value = zero, upper range value = upper range limit).
Zero Trim
A zero trim is a single-point adjustment used for compensating mounting position and line
pressure effects. When performing a zero trim, ensure that the equalizing valve is open and
all wet legs are filled to the correct level.
If zero offset is less than 3% of true zero, follow the “Using the HART Communicator”
instructions below to perform a zero trim. If zero offset is greater than 3% of true zero,
follow the “Using the Transmitter Zero Adjustment Button” instructions below to rerange. If
hardware adjustments are not available, see the 3051 Reference Manual (document
number 00809-0100-4051) to perform a rerange using the HART Communicator.
Using the HART Communicator

SAFETY INSTRUMENTED SYSTEMS
Additional Safety Instrumented Systems information is available in the Rosemount 3051
reference manual (document number 00809-0100-4051). The manual is available
electronically on www.emersonprocess.com/rosemount or by contacting an Emerson
Process Management representative.
3051 Safety Certified Identification
All 3051 transmitters must be identified as safety certified before installing into SIS
systems. To identify a safety certified 3051, verify that QT is included in the transmitter
model code.
Installation
No special installation is required in addition to the standard installation practices outlined
in this document. Always ensure a proper seal by installing the electronics housing cover(s)
so that metal contacts metal.
Environmental limits are available in the 3051 Product Data Sheet
(document number 00813-0100-4051). This document can be found at
www.emersonprocess.com/rosemount/safety/certtechdocumentation.htm.
The loop should be designed so the terminal voltage does not drop below 10.5 Vdc when
the transmitter output is 22.5 mA.
If hardware security switches are installed, the security switch should be in the “ON”
position during normal operation. See Figure 5 on page 7. If hardware security switches are
not installed, security should be “ON” in the software to prevent accidental or deliberate
change of configuration data during normal operation.
Configuration
Use any HART-compliant master to communicate with and verify configuration of the 3051
SIS (see Table 1 on page 11 and 9 to verify configuration). User-selected damping will
affect the transmitters ability to respond to changes in the applied process. The damping
value + response time should not exceed the loop requirements.
NOTE
Transmitter output is not safety-rated during the following: configuration changes,
multidrop, and loop test. Alternative means should be used to ensure process safety during
transmitter configuration and maintenance activities.
Alarm and Saturation Levels
DCS or safety logic solver should be configured to match transmitter configuration. Figure 8
identifies the three alarm levels available and their operation values.
