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 (document number 00809-0100-4108) for more information. This manual is also available
electronically on www.emersonprocess.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. Only
use plugs, adapters, glands or conduit with a compatible thread form when closing these entries.

System readiness
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 your transmitter, see
page 15.
Confirm correct device driver
Verify the latest Device Driver (DD/DTM) is loaded on your systems to ensure
proper communications.
Download the latest Device Driver files at www.emersonprocess.com or
www.hartcomm.org.
Note
The 2088, 2090F, and 2090P transmitters all use 2088 Device Revisions and Drivers.
1. Download the latest DD at www.emersonprocess.com or
www.hartcomm.org.

Quick Start Guide
Table 1. Rosemount 2088 Device Revisions and Files
Step 1: Mount the transmitter
Rosemount 2088
Mount directly to the impulse line without using an additional mounting bracket
or mount directly to a wall, panel, or two-inch pipe using an optional mounting
bracket.
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 reference manual for
complete welding instructions (document number 00809-0100-4690). Improper
installation may result in weld spud distortion. Upright or horizontal position
mounting is recommended to allow proper draining of vent.
Rosemount 2090F
Mount directly to the process pipe using a standard sanitary fitting (either a
1.5-in. or 2-in.Tri Clamp connection). Upright or horizontal position mounting is
recommended to allow proper draining of vent.

Quick Start Guide
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.)
Liquid flow applications
1. Place taps to the side of the line.
2. Mount beside or below the taps.
3. Mount the transmitter so the drain/vent
valves are oriented upward.
Gas flow applications
1. Place taps in the top or side of the line.
2. Mount level or above the taps.
Steam flow applications
1. Place taps to the side of the line.
2. Mount beside or below the taps.
3. Fill impulse lines with water.
Keep the vent path free of any obstruction, including but not limited to paint, dust, and lubrication by
mounting the transmitter so the contaminants can drain away.

Step 2: 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.

Step 3: 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 feet (1500 meters) 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 teminals
Use the following steps to wire the transmitter:
1. Remove the housing cover on the FIELD TERMINALS side.
2. Connect the leads and shown in Figure 5 or Figure 6.
3. Ground housing to fulfill local grounding regulations.
4. 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
5. If transient protection is needed, refer to section Grounding for transient
terminal block for grounding instructions.
6. Plug and seal unused conduit connections.
7. Replace the housing cover.
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.

Figure 7. Grounding
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).
If the transmitter is currently not wired for power up and communication, follow
procedures 1-7 of “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.
Step 4: Verify transmitter configuration
Verify the configuration using any HART capable configuration tool or Local
Operator Interface (LOI) - option code M4. Configuration instructions for a Field
Communicator and LOI are included in this step. See Rosemount 2088 Reference
Manual (document number 00809-0100-4108) for configuration instructions
using AMS®Device Manager.
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.
