4200 Transmitters

July 2013

Check with your process or safety engineer for any additional measures that must be taken to protect against process

media.

If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this

instruction manual.

When a 4200 transmitter is ordered with an actuator, the factory mounts the transmitter and adjusts the zero and

span for the travel specified on the order. Make field wiring connections as described in the electrical connections

procedure and fine tune the transmitter to the application. Refer to the appropriate actuator and valve instruction

manuals to install the attached assemblies.

If the transmitter has been ordered separately, or removed for maintenance, perform the appropriate portion of the

Mechanical Connections, Electrical Connections, Potentiometer Alignment, and Calibration procedures.

The transmitter can be mounted in any of four positions. Mount the transmitter vertically or horizontally depending on

the application requirements. Refer to figures 15 through 23 for examples of typical actuator mounting assemblies.

As an aid to installation, and to understand the transmitter design in general, refer to figure 2 to see the location of the

transmitter compartment and the field wiring compartment. The transmitter compartment contains the transmitter

and/or the position switch circuit on the printed wiring board, associated wiring assemblies, adjustment

potentiometers, and the potentiometer that senses position. Remove the cover on the transmitter compartment to

gain access to this compartment. Note that you will need to loosen the set screw (key 106) before removing the cover.

The transmitter compartment is adjacent to the

symbol on the housing.

Except for a 4211 or 4221 transmitter, the field wiring compartment contains a printed wiring board with the terminal

blocks (figure 4) for connecting field wiring and associated cable assemblies. It also contains the position switch relays

which are mounted on the printed wiring board. Remove the cap adjacent to the + and - symbols on the housing to

access this compartment. Note that you will need to loosen the set screw (key 106) before removing the cover.

For a 4211 or 4221 transmitter without position switch circuits, the field wiring compartment contains a barrier strip

for installation of the transmitter field wiring (figure 4).

Figure 2 shows the location of the ports into the field wiring compartment. Two ports are available for routing the

transmitter and/or position switch wiring into the transmitter housing. After transmitter installation, install a plug in

the unused port. When installing the transmitter, allow sufficient space for removing the covers to perform

maintenance and to make the wiring connections. Figure 2 also shows the basic transmitter outline dimensions.

Hazardous Area Classifications and Special Instructions for “Safe Use” and

Installations in Hazardous Locations

Certain nameplates may carry more than one approval, and each approval may have unique installation/wiring

requirements and/or conditions of “safe use”. These special instructions for “safe use” are in addition to, and may

override, the standard installation procedures. Special instructions are listed by approval.

Note

This information supplements the nameplate markings affixed to the product.

Always refer to the nameplate itself to identify the appropriate certification. Contact your Emerson Process Management sales

office for approval/certification information not listed here.
