IMPORTANT NOTICE
This installation guide provides basic guidelines for the Rosemount 3095FB MultiVariable
Transmitter with MODBUS Protocol (reference manual document number
00809-0100-4738). It does not provide instructions for configuration, diagnostics,
maintenance, service, or troubleshooting. Refer to the appropriate reference manual for
more instruction. These manuals are 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.
• Before connecting communications 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.
• 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.

STEP 2: CONSIDER HOUSING ROTATION
Consider Housing Rotation
To improve field access or to better view the optional LCD display:
1. Loosen the housing rotation set screw.
2. Rotate the housing clockwise to the desired position – up to 180° from its original position.
Over rotating will damage the transmitter.
3. If the desired position is attained, tighten the housing rotation set screw.
4. If the desired position cannot be reached because the housing will not rotate further,
rotate the housing counterclockwise until in the desired position is attained (up to 180°
from its original position).
5. Tighten the housing rotation set screw.
Field Installation
1. Mount the transmitter
a.Install the flange or flange/adapter bolt finger-tight.
b.Torque bolts to initial torque value using a cross pattern (see Table 1). When
installing to a mounting bracket, torque bolts to 125 in./lb (169 N/m)
2. If security jumpers are not installed, the transmitter will operate normally with the default
security off. Verify baud rate. Default baud rate is 9600 with switch S1 and S2 in on
position. Verify AC termination, pull down (B), and pull up (A) switches; default is in the off
position.

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 6 illustrates common transmitter assemblies with the bolt
length required for proper transmitter assembly.
Figure 6. 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 7. If bolt material is not shown in
Figure 7, 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 7 for initial
torque value.
4. Torque the bolts to the final torque value using the same crossing pattern. See Figure 7
for final torque value.
5. Verify that the flange bolts are protruding through the isolator plate before applying
pressure.

O-rings with Flange Adapters
WARNING
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 the o-rings are replaced, re-torque
the flange bolts and alignment screws after installation to compensate for seating of the
PTFE o-ring.

Failure to install proper flange adapter O-rings may cause process leaks, which can result in death or
serious injury. The two flange adapters are distinguished by unique O-ring grooves. Only use the O-ring
that is designed for its specific flange adapter, as shown below.

STEP 3: 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 lead from the positive power supply terminal to the “+” terminal
(PWR/COMM) and the lead from the negative power supply terminal to the “–” terminal.
3. Connect the transmitter to the RS-485 bus:
Connect the A lead to the “A” terminal.
Connect the B lead to the “B” terminal.
NOTE
Improper field wiring connections may damage the 3095FB. Do not connect power wiring to
the RS-485 terminals. Twisted pairs should be used for best results. Twisted pair is required
for RS-485 bus wiring. Runs under 1000 ft (305 m) should be AWG 22 or larger. Runs from
1000 to 4000 feet (305 to 1219 m) should be AWG 20 or larger. Wiring should not exceed
AWG 16.
4. Plug and seal unused conduit connections.
5. Install wiring with a drip loop. Arrange the drip loop so the bottom is lower than the
conduit connections and the transmitter housing.
Figure 8 shows wiring connections necessary to power a 3095 and enable communications.
The 3095FB requires a power supply between 7.5 - 30 Vdc. RS-485 signal wiring requires
2-wire half duplex RS-485 Modbus with 8 data bits, one stop bit, and no parity.
Figure 8. Transmitter Wiring Di agram
NOTE
Installation of the transient protection terminal block does not provide transient protection
unless the 3095 case is properly grounded. The converter cables may be connected directly
to the RS-485 bus or the transmitter terminals. Be sure to observe proper polarity.

STEP 5: TRIM THE TRANSMITTER
NOTE
Transmitters are shipped from Emerson Process Management, Rosemount Division fully
calibrated per request or by the factory default of full scale.
Zero Offset Trim
A zero trim is a single-point adjustment used for compensating mounting position effects.
When performing a zero trim, ensure the low side block valve is closed, the equalize valve is
open, the high side block 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 user interface software instructions
below.
Trim DP Offset (Zero)
1. Click Maintenance, Sensor Trim on the taskbar.
2. Click DP option.
3. click Offset Trim option.
4. Enter the offset trim point to trim DP Offset (Zero)
5. Click Trim to complete the sensor trim
Trim SP Offset (Zero) (AP, GP)
1. When performing a offset or zero SP trim, ensure the low side block valve is closed, the
equalize valve is open, and the high side block valve is closed. Then, open vent to
atmosphere.
2. Click Maintenance, Sensor Trim on the taskbar.
3. Click SP option.
4. click Offset Trim option.
5. If using GP type sensor, enter zero.
If using AP type sensor, do not zero. Instead, enter an Offset value based on a
barometric pressure reading.
NOTE
For Absolute Pressure (AP) Sensor: If open to atmosphere, reading should be at
atmospheric pressure (roughly 12 - 15 psi (0.8 – 1.0 bar), not zero. Use a barometer that is
four times as accurate as the Rosemount 3095 AP sensor.
6. Click Trim to complete the sensor trim.
7. Once the offset or zero SP trim is complete, verify that vent is closed, the high side block
valve is open, close the equalize valve tightly, then open the low side block valve.
