STEP 1: IDENTIFY ALL 3051S ERS SYSTEMS COMPONENTS
A complete 3051S 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 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 3051S ERS system:
• For new installations or applications, the second 3051S ERS sensor may have been shipped
in a separate box.
• If servicing or replacing part of an existing 3051S ERS system, the other sensor may already
be installed.
STEP 2: MOUNT EACH 3051S ERS SENSOR
Mount the PHI and PLO sensors at the correct process connections for the application. Common
3051S ERS installations are shown in Figure 1 and Figure 2.
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.

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
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
Bolts are typically carbon steel or stainless steel. Confirm the material by viewing the marking on
the head of the bolt and referencing Figure 6. If bolt material is not shown in Figure 6, 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 Figure 6 for initial
torque value.
4. Torque the bolts to the final torque value using the same crossing pattern. See Figure 6 for
final torque value.
5. Verify that the flange bolts are protruding through the module isolator plate before applying
pressure (See Figure 5).

STEP 3: CONSIDER HOUSING ROTATION
NOTE
Do not rotate the housing on each transmitter more than 180 degrees without first performing a
disassembly procedure (see Section 2 of the 3051S ERS System reference manual
(00809-0100-4804) for more information). Over-rotation may sever the electrical connection
between the sensor module and feature board electronics.
STEP 4: SET SWITCHES
If the 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.
Figure 7. Transmitter Switch Configuration
To improve field access to wiring or to better view the
optional LCD display:
1. Loosen the housing rotation set screw.
2. Turn the housing up to 180° left or right of its
original (as shipped) position.
3. Retighten the housing rotation set screw.

Wiring Diagrams
Figure 8 - Figure 10 show the wiring connections necessary to power a 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 3051S ERS
system to malfunction if placed in between any of the 3051S ERS sensors.
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 & 2) must be 22 AWG minimum and the communication wires (pin
terminals A & B) must be 24 AWG minimum.
Cable Length: Up to 100 feet (31 m) depending upon cable capacitance.
Cable Capacitance: The capacitance between the communication terminals (pin terminals A &
B) as wired must be less than 5000 picofarads total. This allows up to 50 picofarads per foot (0.3
m) for a 100 foot (31 m) cable.
Cable Outside Diameter (O.D): 0.270 inches (6.86 mm)

The items in Table 2 are considered “optional” and can be configured as necessary:
STEP 7: CALIBRATE THE 3051S ERS SYSTEM
Each 3051S ERS sensor is shipped fully calibrated per request or with the factory default of full
scale. After the 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 on a vented tank. 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.
3051S ERS System Calibration
1. Equalize or vent both 3051S ERS sensors and connect a Field Communicator as shown in
Figure 8 – Figure 10.
2. Input the following key sequence on the Field Communicator to trim each sensor and the DP
reading. Follow the commands prompted by the Field Communicator.
NOTES:
1. The “System DP Zero Trim” should be performed after the P-Hi and P-Lo sensor trims.
2. Refer to the 3051S ERS reference manual for the recommended calibration procedure for
performing a sensor trim at line pressure.
