Explosion-Proof, Flame-Proof, or intrinsically safe (I.S.) installations. Refer to the 2051 reference
manual (document number 00809-0200-4101) for more instruction. This manual is also
available electronically on www.emersonprocess.com/rosemount.
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 2051 reference manual for any restrictions associated with a safe
installation.
In an Explosion-proof/Flameproof installation, do not remove the transmitter covers when
power is applied to the unit.
Process leaks may cause harm or result in death.
To avoid process leaks, only use the o-ring designed to seal with the corresponding flange
adapter.
Electrical shock can result in death or serious injury.
Avoid contact with the leads and the terminals. High voltage that may be present on leads can
cause electrical shock.
Conduit/cable entries
Unless marked, the conduit/cable entries in the transmitter housing use a 1/2-14 NPT thread
form. Only use plugs, adapters, glands, or conduit with a compatible thread form when
closing these entries.

Bolts are typically carbon steel or stainless steel. Confirm the material by viewing
the markings on the head of the bolt and referencing Table 2 on page 7. If bolt
material is not shown in Table 2, contact a local Emerson Process Management
representative for more information.
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.
Use the following bolt installation procedure:
1. Finger tighten the bolts.
2. Torque the bolts to the initial torque value using a crossing pattern. See Table 2
for initial torque value.
3. Torque the bolts to the final torque value using the same crossing pattern. See
Table 2 for final torque value.
4. Verify the flange bolts are protruding through the sensor module bolt holes
before applying pressure.

Quick Start Guide
Whenever the flanges or adapters are removed, visually inspect the o-rings.
Replace them if there are any signs of damage, such as nicks or cuts. If you replace
the o-rings, re-torque the flange bolts and alignment screws after installation to
compensate for seating of the PTFE o-ring.
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 5.)
Keep the vent path free of any obstruction, including but not limited to paint,
dust, and lubrication by mounting the transmitter so that fluids can drain away.

3. If the desired location cannot be achieved due to thread limit, rotate the
housing counter clockwise to the desired location (up to 360° from thread
limit).
4. Re-tighten the housing rotation set screw to no more than 7 in-lbs when
desired location is reached.
Step 4: Set the switches
Set Simulate and Security switch configuration before installation as shown in
Figure 8.
The simulate switch enables or disables simulated alerts and simulated AI
Block status and values. The default simulate switch position is enabled.
The Security switch allows (unlocked symbol) or prevents (locked symbol)
any configuration of the transmitter.
- Default security is off (unlocked symbol).
- The security switch can be enabled or disabled in software.
Use the following procedure to change the switch configuration:
1. If the transmitter is installed, secure the loop, and remove power.
2. Remove the housing cover opposite the field terminal side. Do not remove the
instrument cover in explosive atmospheres when the circuit is live.
3. Slide the security and simulate switches into the preferred position.
4. Replace the housing cover.
Note
It is recommended the cover be tightened until there is no gap between the cover and housing.

Step 5: Wire, ground, and power up
Use of copper wire of sufficient size to ensure that the voltage across the
transmitter power terminals does not drop below 9 vdc. Power supply voltage can
be variable, especially under abnormal conditions such as when operating on
battery backup. A minimum of 12 vdc under normal operating conditions is
recommended. Shielded twisted pair Type A cable is recommended.
1. To power the transmitter, connect the power leads to the terminals indicated
on the terminal block label.

B. Trim shield and insulate
C. Protective Grounding Terminal (do not ground cable shield at the transmitter)
D. Insulate Shield
E. Minimize distance
F. Connect Shield Back to the Power Supply Ground
Note
The 2051 power terminals are polarity insensitive, which means the electrical polarity of the power
leads does not matter when connecting to the power terminals. If polarity sensitive devices are
connected to the segment, terminal polarity should be followed. When wiring to the screw
terminals, the use of crimped legs is recommended.
2. Tighten the terminal screws to ensure adequate contact. No additional power
is needed.
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
electronics housing and inside the Terminal Compartment. These grounds are
used when transient protect terminal blocks are installed or to fulfill local
regulations.
1. Remove the Field Terminals housing cover.
2. Connect the wiring pair and ground as indicated in Figure 9.
a. Trim the cable shield as short as practical and insulate from touching the
transmitter housing.

Quick Start Guide
Note
Do NOT ground the cable shield at the transmitter; if the cable shield touches the
transmitter housing, it can create ground loops and interfere with communications.
b. Continuously connect the cable shields to the power supply ground.
c. Connect the cable shields for the entire segment to a single good earth
ground at the power supply.
Note
Improper grounding is the most frequent cause of poor segment communications.
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.
Power supply
The transmitter requires between 9 and 32 V dc (9 and 30 V dc for intrinsic safety,
and 9 and 17.5 V dc for FISCO intrinsic safety) to operate and provide complete
functionality.
Power conditioner
A fieldbus segment requires a power conditioner to isolate the power supply,
filter, and decouple the segment from other segments attached to the same
power supply.
Grounding
Signal wiring of the fieldbus segment can not be grounded. Grounding out one of
the signal wires will shut down the entire fieldbus segment.
Shield wire ground
To protect the fieldbus segment from noise, grounding techniques for shield wire
require a single grounding point for shield wire to avoid creating a ground loop.
Connect the cable shields for the entire segment to a single good earth ground at
the power supply.
Signal termination
For every fieldbus segment a terminator should be installed at the beginning and
at the end of each segment.

automatically returns to normal operation.
Note
Some hosts do not support “Locate Device” in the DD.
Step 6: Configure
Each FOUNDATION fieldbus host or configuration tool has a different way of
displaying and performing configurations. Some use Device Descriptions (DD) or
DD methods for configuration and to display data consistently across platforms.
There is no requirement that a host or configuration tool support these features.
Use the following block examples to do basic configuration to the transmitter. For
more advanced configurations see the 2051 reference manual (document
number 00809-0200-4101, Rev. BA).
Note
DeltaV users should use DeltaV Explorer for the Resource and Transducer blocks and Control
Studio for the Function Blocks.
Configure the AI block
If your configuration tool supports Dashboard DD's or DTM's you may use either
guided setup or manual setup. If your configuration tools don't support
Dashboard DD's or DTM's, use manual setup. Navigation instructions for each
step are provided below. In addition the screens used for each step are shown in
