2.3 Models covered
The Rosemount ERS System is a flexible, 2-wire HART® architecture that calculates differential pressure
(DP) electronically, using two pressure sensors. The pressure sensors are linked together with an
electrical cable and synchronized to create a single Rosemount ERS System. The sensors used in the
Rosemount ERS System can consist of any combination of Rosemount 3051SAM and 3051SAL models.
One of the sensors is required to be a “Primary” and the other is required to be a “Secondary.”
The Primary sensor contains the 4–20 mA loop termination and optional LCD display. The Secondary
sensor is made up of a pressure sensor module and junction box housing that is connected to the
primary sensor, using a standard instrument cable.

Mount each Rosemount 3051S ERS Transmitter close to the process and use minimum piping to achieve
best performance. Also, consider the need for easy access, personnel safety, practical field calibration,
and a suitable environment. Install each sensor to minimize vibration, shock, and temperature
fluctuation.
Note
Install the enclosed pipe plugs (found in the box) in any unused conduit openings. For proper straight
and tapered thread engagement requirements, see the appropriate approval drawings in Product Data
Sheet. For material compatibility considerations, see Material Selection Technical Note.
2.4.2 Mechanical
For dimensional drawing information, refer to Product Data Sheet.
For steam service or for applications with process temperatures greater than the limits of each
Rosemount 3051S ERS Transmitter, do not blow down impulse piping through either sensor. Flush lines
with the blocking valves and refill lines with water before resuming measurement.
If a Rosemount 3051S ERS Transmitter is mounted on its side, position the flange/manifold to ensure
proper venting or draining.
Field terminal side of housing
Installation
Mount each Rosemount ERS Sensor so the terminal side is accessible. Clearance of 0.75-in. (19 mm) is
required for cover removal.

Cover installation
Always ensure a proper seal by installing the housing covers so that metal contacts metal in order to
prevent performance degradation due to environmental effects. For replacement cover O-rings, use
Rosemount O-rings (part number 03151-9040-0001).
Conduit entry threads
For NEMA® 4X, IP66, and IP68 requirements, use thread seal (PTFE) tape or paste on male threads to
provide a watertight seal.
Cover jam screw
For housings shipped with a cover jam screw (as shown in Figure 2-2), the screw should be properly
installed once the Rosemount ERS System has been wired and powered up. The cover jam screw is
intended to prevent the removal of the housing covers in flameproof environments without the use of
tools. Follow these steps to install the cover jam screw:
1. Verify the cover jam screw is completely threaded into the housing.
2. Install the housing covers and verify that metal contacts metal in order to meet
flameproof/explosion-proof requirements.
3. Using an M4 hex wrench, turn the jam screw counterclockwise until it contacts the housing cover.
4. Turn the jam screw an additional
excessive torque may strip the threads.
5. Verify the covers cannot be removed.

Flange bolts
An Rosemount 3051S ERS Transmitter can be shipped with a coplanar flange or a traditional flange
installed with four 1.75-in. flange bolts. Mounting bolts and bolting configurations for the coplanar and
traditional flanges can be found on Tabl e 2-2 . Stainless steel bolts supplied by Emerson are coated with a
lubricant to ease installation. Carbon steel bolts do not require lubrication. No additional lubricant
should be applied when installing either type of bolt. Bolts supplied by Emerson are identified by their
head markings:
Bolt installation
Only use bolts supplied with the Rosemount 3051S ERS Transmitter or sold by Emerson as spare parts.
Use the following bolt installation procedure:
1. Finger-tighten the bolts.
2. Torque the bolts to the initial torque value using a crossing pattern. For initial torque values, see
Ta bl e 2 - 2.
3. Torque the bolts to the final torque value using the same crossing pattern. For final torque values, see
Ta bl e 2 - 2.
Torque values for the flange and manifold adapter bolts are as follows:

To install adapters to a coplanar flange, perform the following procedure:
1. Remove the flange bolts.
2. Leaving the flange in place, move the adapters into position with the O-rings installed.
3. Attach the adapters and the coplanar flange to the transmitter sensor module assembly using the
longer of the bolts supplied.
4. Tighten the bolts. Refer to Table 2-2 on page 10 for torque specifications.
Use only the O-rings included with the flange adapter for the Rosemount 3051S ERS Transmitter. 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.
Impulse piping
The piping between the process and each Rosemount 3051S ERS Transmitter must accurately transfer
the pressure to obtain accurate measurements. There are many possible sources of error: pressure
transfer, leaks, friction loss (particularly if purging is used), trapped gas in a liquid line, liquid in a gas line,
and plugged impulse lines.
The best location for each Rosemount 3051S ERS Transmitter depends on the process itself. Use the
following guidelines to determine sensor location and placement of impulse piping:
Keep impulse piping as short as possible.
For liquid service, slope the impulse piping at least 1 inch per foot (8 cm per m) upward from the
transmitter toward the process connection.
For gas service, slope the impulse piping at least 1 inch per foot (8 cm per m) downward from the
transmitter toward the process connection.
Avoid high points in liquid lines and low points in gas lines.
When purging, make the purge connection close to the process tap and purge through equal lengths
of the same size pipe. Avoid purging through either Rosemount 3051S ERS Transmitter.
Keep corrosive or hot (above 250 °F or 121 °C) process material out of direct contact with the sensor
module process connection and flanges.
Prevent sediments from depositing in the impulse piping.
Note
Take necessary steps to prevent process fluid from freezing with the process flange to avoid damage to
each Rosemount 3051S ERS Transmitter.

Note
Verify the zero point on each Rosemount 3051S ERS Transmitter after installation. To reset the zero trim,
refer to “Calibration overview” on page 44.

2.5.4 Consider housing orientation
Housing rotation
The housing can be rotated to improve access to wiring or to better view the LCD display (if ordered). To
rotate the housing, perform the following procedure:
1. Loosen the housing set screw.
2. Turn the housing up to 180° to the left or right of its original (as shipped) position.
Note
Do not rotate the housing more than 180° from its original position without first performing a
disassembly procedure (see page 49). Over rotation may sever the electrical connection between the
sensor module and the electronics feature board.
3. Retighten the housing rotation set screw.

2.5.5 Configure security and alarm
Security switch
Changes to the Rosemount ERS System configuration can be prevented with the security (write protect)
switch, which is located on the electronics feature board of the Rosemount 3051S ERS Primary
Transmitter. See Figure 2-9 for the location of the switch. Position the switch in the “ON” position to
prevent accidental or deliberate change to the Rosemount ERS System configuration.
If the write protect switch is in the “ON” position, the Rosemount ERS System will not accept any “writes”
to its memory. Configuration changes, such as digital trim and reranging, cannot take place when the
security switch is set to “ON.”
Alarm direction
The alarm direction of the analog output of the Rosemount ERS System is set by repositioning the alarm
switch, which is located on the electronics feature board of the primary transmitter. Position the switch
in the “HI” position to have the Rosemount ERS System go to high alarm in a fail condition, or position
the switch in the “LO” position to have the system go to low alarm in a fail condition. See “Alarm and
saturation levels” on page 29 for more information on alarm and saturation levels.
Switch configuration procedure
Reference Manual
00809-0100-4804, Rev DA
To reposition the hardware switches, follow the procedure below:
1. Do not remove the housing covers in explosive atmospheres when the circuit is live. If the Rosemount
3051S ERS System is live, set the loop to manual and remove power.
2. On the Rosemount 3051S ERS Primary Transmitter, remove the housing cover opposite the field
terminal side.
3. Reposition the alarm and security switches as desired, by using a small screwdriver.
4. Reinstall the housing cover. Covers must be fully engaged so the metal contacts metal in order
to meet flameproof/explosion-proof requirements.

Rosemount 3051S ERS System cable specifications
Cable type: Recommend gray Madison 04ZZXLF015 cable, blue Madison 04ZZXLF021 cable, and
Southwire HLX-SPOS two pairs armor 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.
Maximum cable length: The total length of cable used to connect the ERS primary transmitter,
secondary transmitter, and remote display (if ordered) should not exceed maximum lengths below.
– Madison (gray cable): up to 500 ft. (152,4 m) for non-IS applications and 225 ft. (68,58 m) for IS
applications; consult Emerson for applications requiring beyond 500 ft.
– Madison (blue cable): up to 225 ft. (68,58 m) for IS applications
– Armored cable: up to 125 ft. (38,1 m)
For SIS maximum lengths see “Rosemount ERS Systems safety certified identification” on page 61
Cable capacitance: The capacitance between the communication lines as wired must be less than
5000 pF total. This allows up to 50 pF per ft. (164 pF/m) for a 100-ft. cable.
Gray and blue cable outside diameter: 0.270-in. (6.86 mm)
Armor cable outside diameter: 0.76-in. (19.3 mm)
For armored cable, cable glands are included with the packaging
4–20 mA loop wiring specifications
It is recommended to use twisted pair wiring. To ensure proper communication, use 24 to 14 AWG wire,
and do not exceed 5000 ft. (1500 m).
Note
There are four connections plus shield, which require correct configuration for operation. There is no
mechanism that can result in re-sequencing of messages from the physical connections.
Surges/transients
The Rosemount 3051S ERS System will withstand electrical transients of the energy level usually
encountered in static discharges or induced switching transients. However, high-energy transients, such
as those induced in wiring from nearby lightning strikes, can damage the Rosemount ERS System.
Optional transient protection terminal block
The transient protection terminal block can be ordered as an installed (option code T1) or as a spare part
to retrofit an existing Rosemount ERS System in the field. A lightning bolt symbol on a terminal block
identifies it as having transient protection.
Note
The transient terminal block is only available as an option on the primary Rosemount 3051S ERS
Transmitter. When ordered and installed, a primary Rosemount 3051S ERS Transmitter with the
transient terminal block will protect the entire Rosemount ERS Assembly including the secondary
Rosemount 3051S ERS Transmitter.
16
Power supply requirements
The DC power supply should provide power with less than two percent ripple. The total loop resistance is
the sum of the resistance from the signal leads and the load resistance of the controller, indicator, and
related pieces. Note that the resistance of intrinsically safe barriers, if used, must be included.
