Quick Start Guide
NOTICE
This guide provides basic guidelines for Rosemount 2088, 2090F, and 2090P Transmitters. It does not provide
instructions for configuration, diagnostics, maintenance, service, troubleshooting, Explosion-proof,
Flameproof, or intrinsically safe (I.S.) installations. See the Rosemount 2088 Reference Manual for more
information. This manual is also available electronically on Emerson.com/Rosemount.
Explosions could result in death or serious injury.
Installation of these transmitters in an explosive environment must be in accordance with the appropriate local,
national, and international standards, codes, and practices. Review the approvals section of the Rosemount
2088 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/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. Entries
marked “M20” are M20 x 1.5 thread form. On devices with multiple conduit entries, all entries will have the same
thread form. Only use plugs, adapters, glands or conduit with compatible thread form when closing these
entries.

1.0 System readiness
1.1 Confirm HART revision capability
If using HART-based control or asset management systems, confirm the
HART capability of those systems prior to transmitter installation. Not all
systems are capable of communicating with HART Revision 7 Protocol. This
transmitter can be configured for either HART Revision 5 or 7.
For instructions on how to change the HART revision of the transmitter, see
page 14.
1.2 Confirm correct device driver
Verify the latest device driver (DD/DTM™) is loaded on your systems to
ensure proper communication.
Note
The Rosemount 2088, 2090F, and 2090P Transmitters all use Rosemount 2088 Device
Revisions and Drivers.

Quick Start Guide
2.0 Mount the transmitter
2.1 Rosemount 2088
Mount directly to the impulse line without using an additional mounting bracket
or mount directly to a wall, panel, or 2-in. pipe using an optional mounting
bracket.
2.2 Rosemount 2090P
Mount directly to the process pipe using an existing weld spud, or have a skilled
welder install a new weld spud using a TIG welder. See Rosemount 2088
Reference Manual for complete welding instructions. Improper installation may
result in weld spud distortion. Upright or horizontal position mounting is
recommended to allow proper draining of vent.
2.3 Rosemount 2090F
Mount directly to the process pipe using a standard sanitary fitting (either a 1.5-
or 2-in.Tri-Clamp®connection). Upright or horizontal position mounting is
recommended to allow proper draining of vent.

2.4 Environmental seal for housing
Thread sealing (PTFE) tape or paste on male threads of conduit is required to
provide a water/dust tight conduit seal and meets requirements of NEMA®Type
4X, IP66, and IP68. Consult factory if other Ingress Protection ratings are
required.
For M20 threads, install conduit plugs to full thread engagement or until
mechanical resistance is met.
Do not apply torque directly to the electronics housing.
To avoid damage, apply torque only to the hex-shaped
process connection.

2.8 Gage transmitter orientation
The low side pressure port (atmospheric reference) on the in-line 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).

3.0 Set the switches
Set alarm and security switch configuration before installation as shown in
Figure 4.
The alarm switch sets the analog output alarm to high or low. Default alarm
is high.
The security switch allows ( ) or prevents ( ) any configuration of the
transmitter. Default security is off ( ).
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 alarm switches into the preferred position using a small
screwdriver.
4. Reattach the transmitter cover. The cover must be fully engaged to comply
with explosion-proof requirements.

4.0 Connect the wiring and power up
Shielded twisted pair cable should be used for best results. Use 24 AWG or larger
wire that does not exceed 5000 ft. (1500 m) in length. 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.

C. Field terminals
Installation of the transient protection terminal block does not provide transient protection
unless the transmitter case is properly grounded.
Do not run signal wiring in conduit or open trays with power wiring, or near heavy electrical
equipment.
Do not connect the powered signal wiring to the test terminals. Power could damage the test
diode in the terminal block.

Use the following steps to wire the transmitter:
1. Remove the housing cover on the FIELD TERMINALS side.
2. Connect the leads as shown in Figure 5 or Figure 6.
3. Tighten the terminal screws to ensure full contact with the terminal block
screw and washer. When using a direct wiring method, wrap wire clockwise
to ensure it is in place when tightening the terminal block screw.
Note
The use of a pin or ferrule wire terminal is not recommended as the connection may be
more susceptible to loosening over time or under vibration.
4. Ground housing to fulfill local grounding regulations.
5. Ensure proper grounding. It is important that the instrument cable shield:
Be trimmed close and insulated from touching the transmitter housing
Be connected to the next shield if cable is routed through a junction box
Be connected to a good earth ground at the power supply end
6. If transient protection is needed, refer to Grounding for transient terminal
block for grounding instructions.
7. Plug and seal unused conduit connections.
8. Replace the housing cover.
Figure 7. Grounding
4.1 Grounding for transient terminal block
Ground termination is provided on the outside of the electronics housing and
inside the terminal compartment. These grounds are used when the transient
protection terminal blocks are installed. It is recommended that 18 AWG or
larger wire is used to connect housing ground to earth ground (internal or
external).

Quick Start Guide
If the transmitter is currently not wired for power up and communication (follow
steps in “Connect the wiring and power up” on page 8. When the transmitter is
properly wired, refer to Figure 7 for internal and external transient grounding
locations.
5.0 Verify transmitter configuration
Verify the configuration using any HART capable configuration tool or LOI -
option code M4. Configuration instructions for a Field Communicator and LOI
are included in this step. See Rosemount 2088 Reference Manual for
configuration instructions using AMS Device Manager.
5.1 Verifying configuration with a Field Communicator
A Rosemount 2088 DD must be installed on the Field Communicator to verify
configuration. Fast Key sequences vary depending on device and DD revisions.
Use the Determine Fast Key sequence table process below to identify the
appropriate Fast Key sequences.
5.2 Field Communicator User Interface
Determine Fast Key sequence table
1. Connect Field Communicator to Rosemount 2088, 2090F, or 2090P.
2. If Home screen matches Figure 8, refer to Table 3 for Fast Key sequences.
3. If Home screen matches Figure 9:
a. Perform Fast Key sequence 1,7,2 to identify Field Revision and HART
Revision.
b. Refer to Table 4 and the appropriate column based on your Field Revision
and HART Revision for Fast Key sequences.
Note
Emerson recommends installing the latest DD to access the complete functionality. Visit
Emerson.com or FieldCommGroup.org.
