Quick Start Guide
NOTICE
This guide provides basic guidelines for the Rosemount 3051S ERS System. It does not provide instructions for
diagnostics, maintenance, service, or troubleshooting. Refer to the Rosemount 3051S ERS Reference Manual
for more instruction. This document is also available electronically on 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. Review the approvals section of the Rosemount
3051S ERS Reference Manual for any restrictions associated with a safe installation.
Before connecting a Field Communicator in an explosive atmosphere, ensure 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.
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.
Conduits/cable entries
Unless otherwise marked, the conduit / cable entries in the Rosemount 3051S ERS housing enclosure use a
1/2–14 NPT form. Only use plugs, adapters, glands, or conduit with a compatible thread form when
closing these entries.

1.0 Identify all Rosemount 3051S ERS System
components
A complete Rosemount ERS system contains two sensors. One is mounted on the
high-pressure (PHI) process connection, and the other is mounted on the
low-pressure (PLO) process connection. An optional remote display and interface
may also be included (not pictured) if ordered.
1. Look at the wire-on tag on the Rosemount 3051S sensor to identify whether it
is configured as the PHI or PLO sensor.
2. Locate the second sensor that will be used in the Rosemount 3051S ERS
system:
For new installations or applications, the second Rosemount 3051S ERS
sensor may have been shipped in a separate box.
If servicing or replacing part of an existing Rosemount 3051S ERS system,
the other sensor may already be installed.
2.0 Mount each Rosemount 3051S ERS
Mount the PHI and PLO sensors at the correct process connections for the
application. Common Rosemount 3051S ERS installations are shown in Figure 1
and Figure 2.
2.1 Vertical installation
In a vertical installation such as on a vessel or distillation column, the PHI sensor
should be installed at the bottom process connection. The PLO sensor should be
installed at the top process connection.

2.4 Bolting
If the installation requires assembly of a process flange, manifold, or flange
adaptors, follow these assembly guidelines to ensure a tight seal for optimal
performance characteristics of the Rosemount 3051S ERS System. Only use bolts
supplied with the transmitter or sold by Emerson™Process Management as spare
parts. Figure 4 illustrates common transmitter assemblies with the bolt length
required for proper transmitter assembly.
Figure 4. Common Transmitter Assemblies
A. Transmitter with coplanar flange
B. Transmitter with coplanar flange and flange adapters
C. Transmitter with traditional flange and flange adapters
Bolts are typically carbon steel or stainless steel. Confirm the material by viewing
the marking on the head of the bolt and referencing Table 1. If bolt material is not
shown in Table 1, contact your local Emerson Process Management
representative for more information.
Use the following bolt installation procedure:
1. Carbon steel bolts do not require lubrication. 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 Table 1 for initial torque value.
4. Torque the bolts to the final torque value using the same crossing pattern.
See Table 1 for final torque value.
5. Verify that the flange bolts are protruding through the module isolator plate
before applying pressure (See Figure 5).

Use only the O-rings included with the flange adapter for the 3051S ERS sensor. Failure to install proper
fitting flange adapter O-rings may cause process leaks, which can result in death or serious injury.
When removing flanges or adapters, visually inspect the PTFE O-rings. Replace them if there are any
signs of damage such as nicks or cuts. If replacing O-rings, re-torque the flange bolts after installation
to compensate for seating of the PTFE O-ring.

Note
Do not rotate the housing on each transmitter more than 180° without first performing a
disassembly procedure (see Section 2 of the Rosemount 3051S ERS Reference Manual for
more information). Over-rotation may sever the electrical connection between the sensor
module and feature board electronics.
4.0 Set switches
If the Rosemount 3051S ERS sensor is equipped with alarm and security hardware
switches, verify the desired configuration (default: alarm = HI, security = OFF).
1. If the sensor is installed, secure the loop and remove power.
2. Remove the housing cover opposite the field terminals side. Do not remove
the housing cover in explosive environments.
3. Slide the security and alarm switches into the preferred positions by using a
small screwdriver.
4. Reinstall the housing cover so that metal contacts metal to meet
explosion-proof requirements.

5.3 Wiring diagrams
Figure 8 to Figure 10 show the wiring connections necessary to power a
Rosemount 3051S ERS System and enable communications with a hand-held
Field Communicator.
Note
The wiring connection between the sensors (and remote housing if applicable) must be
made directly. An intrinsically safe barrier or other high-impedance device will cause the
Rosemount 3051S ERS System to malfunction if placed in between any of the Rosemount
3051S ERS sensors.
5.4 Rosemount 3051S ERS cable specifications
Cable type: Recommend Madison AWM Style 2549 cable. Other comparable
cable may be used as long as it has independent dual twisted shielded pair wires
with an outer shield. The power wires (pin terminals 1 and 2) must be 22 AWG
minimum and the communication wires (pin terminals A and B) must be 24 AWG
minimum.
Cable length: Up to 150 ft (45,7 m) depending upon cable capacitance.
Cable capacitance: The capacitance between the communication terminals (pin
terminals A and B) as wired must be less than 5000 picofarads total. This allows
up to 50 picofarads per ft (0,3 m) for a 100 ft (31 m) cable.

7.0 Calibrate the Rosemount 3051S ERS System
Each Rosemount 3051S ERS sensor is shipped fully calibrated per request or with
the factory default of full scale. After the Rosemount 3051S ERS System has been
installed and wired, either a zero trim or a lower sensor trim should be performed
on each sensor to compensate for installation effects.
A zero sensor trim should be performed after installing a gage sensor. A zero
sensor trim should not be performed on an absolute sensor or on a gage
sensor that is at line pressure.
A lower sensor trim should be performed after installing an absolute sensor or
a gage sensor that is at line pressure.
Additionally, a “System DP Zero” trim should be performed to establish a
zero-based DP reading. The “System DP Zero” trim should be performed after a
zero/lower trim has been performed on each sensor.
The steps outlined below detail the procedures for the sensor trims and the
“System DP Zero” trim.
7.1 Rosemount 3051S ERS System calibration
1. Equalize or vent both Rosemount 3051S ERS sensors and connect a Field
Communicator as shown in Figure 8 to Figure 10.
2. Input the following Fast Key sequence on the Field Communicator to trim each
sensor and the DP reading. Follow the commands prompted by the Field
Communicator.
Note
1. The “System DP Zero Trim” should be performed after the P-Hi and P-Lo sensor trims.
2. Refer to the Rosemount 3051S ERS Reference Manual for the recommended calibration
procedure for performing a sensor trim at line pressure.
