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 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.
