Safety messages

This guide provides basic guidelines for the Rosemount 2051HT Transmitter. It does not provide

instructions for configuration, diagnostics, maintenance, service, troubleshooting, Explosion-proof,

Flameproof, or intrinsically safe (I.S.) installations.

CAUTION

The products described in this document are NOT designed for nuclear-qualified applications. Using

non-nuclear qualified products in applications that require nuclear-qualified hardware or products may

cause inaccurate readings. For information on Rosemount nuclear-qualified products, contact your

local Emerson Sales Representative.

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. Review the approvals section of this

manual for any restrictions associated with a safe

•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.

•Do not attempt to loosen or remove flange bolts while the transmitter is in service.

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.

•Before connecting a handheld 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.

Physical access

•Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of

end users’ equipment. This could be intentional or unintentional and needs to be protected

against.

•Physical security is an important part of any security program and fundamental to protecting your

system. Restrict physical access by unauthorized personnel to protect end users’ assets. This is

true for all systems used within the facility.

WARNING

Replacement equipment or spare parts not approved by Emerson for use as spare parts could

reduce the pressure retaining capabilities of the transmitter and may render the instrument

dangerous.

•Use only bolts supplied or sold by Emerson as spare parts.

Improper assembly of manifolds to traditional flange can damage sensor module.

For safe assembly of manifold to traditional flange, bolts must break back plane of flange web (i.e., bolt

hole) but must not contact sensor module housing.

1 System readiness

1.1 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 Switch HART Revision mode.

1.2 Confirm correct device driver

•Verify the correct device driver (DD/DTM™) is loaded on your systems to

ensure proper communications.

•Download the correct device driver at your host vendor download site,

Emerson.com or Fieldbus.org.

2.4 Bolting considerations

If the transmitter installation requires assembly of the process flanges,

manifolds, or flange adapters, follow the 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 2-2 illustrates common transmitter assemblies with the bolt length

required for proper transmitter assembly.

Bolts are typically carbon steel (CS) or stainless steel (SST). Confirm the

material by viewing the markings on the head of the bolt and referencing

Table 2-1. If bolt material is not shown in Table 2-1, contact a local Emerson

representative for more information.

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.

Use the following bolt installation procedure:

Procedure

1. Tighten the bolts by hand.

2. Torque the bolts to the initial torque value using a crossing pattern.

See Table 2-1 for initial torque value.

3. Torque the bolts to the final torque value using the same crossing

pattern. See Table 2-1 for final torque value.

4. Verify the flange bolts are protruding through the sensor module

bolt holes before applying pressure.

2.5 O-rings

The two styles of Rosemount flange adapters (Rosemount 1151 and

Rosemount 3051/2051/2024/3095) each require a unique O-ring (see

Figure 2-3). Use only the O-ring designed for the corresponding flange

adapter.

WARNING

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. When compressed, PTFE O-

rings tend to cold flow, which aids in their sealing capabilities.
