Installation
WARNING
Always wear protective clothing and
eyewear when performing any
installation operations to avoid
personal injury.
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 the 4200 Series transmitters are 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 3 which
shows 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.
The transmitter compartment is adjacent to the
symbol on the housing.
Except for a Type 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.
For a Type 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 3 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
