IMPORTANT NOTICE
This installation guide provides basic guidelines for Rosemount® Model 3051
transmitters. It does not provide instructions for configuration, diagnostics,
maintenance, service, troubleshooting, Explosion-Proof, Flame-Proof, or
intrinsically safe (I.S.) installations.
Refer to the Model 3051 reference manual (document number
00809-0100-4001) for more instruction. This manual is also available
electronically on www.rosemount.com.
WARNING
Explosions could result in death or serious injury:
Installation of this transmitter in an explosive environment must be in
accordance with the appropriate local, national, and international standards,
codes, and practices. Please review the approvals section of the
Model 3051 reference manual for any restrictions associated with a safe
installation.
• Before connecting a HART-based communicator in an explosive
atmosphere, make sure the instruments in the loop are installed in
accordance with intrinsically safe or non-incendive field wiring practices.
• In an Explosion-Proof/Flame-Proof installation, do not remove the
transmitter covers when power is applied to the unit.
Process leaks may cause harm or result in death.
• Install and tighten process connectors before applying pressure.
Electrical shock can result in death or serious injury.
• Avoid contact with the leads and terminals. High voltage that may be
present on leads can cause electrical shock.

STEP 2: CONSIDER HOUSING ROTATION
STEP 3: SET THE JUMPERS
If alarm and security jumpers are not installed, the transmitter will
operate normally with the default alarm condition alarm high and the
security off.
Housing Rotation
To improve field access or to
better view the optional LCD
meter:
1. Loosen the housing rotation
set screw.
2. Turn the housing left or right up
to 180° from its original
position. Over rotating will
damage the transmitter.
3. Retighten the set screw.

STEP 4: CONNECT THE WIRING AND POWER UP
Use the following steps to wire the transmitter:
1. Remove the housing cover on the side marked FIELD
TERMINALS.
2. Connect the positive lead to the "+" terminal, and the negative lead
to the "–" terminal.
NOTE
Do not connect the powered signal wiring to the test terminals. Power
could damage the test diode in the test connection. Shielded, twisted
pair cable should be used for best results. Use 24 AWG or larger wire
and do not exceed 5,000 feet (1 500 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.
Figure 2 shows wiring connections necessary to power a Model 3051
and enable communications with a hand-held HART communicator.
For low-power transmitters, refer to the reference manual.

Wiring in the Field Transient Wiring
Installation of the transient protection terminal block does not provide
transient protection unless the Model 3051 case is properly grounded.

Power Supply
The dc power supply should provide power with less than two percent
ripple. The total resistance load is the sum of the resistance of the
signal leads and the load resistance of the controller, indicator, and
related pieces. Note that the resistance of intrinsic safety barriers, if
used, must be included.

Maximum Loop Resistance = 43.5 (Power Supply Voltage – 10.5)
The HART communicator requires a
minimum loop resistance of 250Ω.

STEP 5: CONFIGURE THE TRANSMITTER
NOTE:
A check (⻫) indicates the basic configuration parameters. At minimum,
these parameters should be verified as part of the configuration and
startup procedure.

STEP 6: TRIM THE TRANSMITTER
NOTE
Transmitters are shipped from Rosemount Inc. fully calibrated per
request or at the factory default of full scale.
Zero Trim
A zero trim is a single-point adjustment used for compensating
mounting position 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 Model
275 HART Communicator” instructions below. If zero offset is greater
than 3% of true zero, follow the “Using the Transmitter Zero
Adjustment Button” instructions below to rerange.
Using the Model 275 HART Communicator
Using the Transmitter Zero Adjustment Button
Fast Keys Steps
1, 2, 3, 3, 1 1. Vent the transmitter and connect HART communicator.
2. At the menu, input the HART Fast Key sequence.
3. Follow the commands to perform a zero trim.
1. Loosen the certifications label screw and
rotate the label to expose the zero
adjustment buttons.
2. Set the 4 mA point by pressing the zero
button for 2 seconds. Verify that the output
is 4 mA. A meter will display ZERO PASS.
