4200 Series Transmitters
Instruction Manual
Form 5596

CAUTION
Connect the transmitter grounding
terminal (key 58) to an earth ground.
Improper grounding of the position
transmitter can cause erratic
operation.
Before making transmitter or position switch
connections, ensure that the power supply is turned
off. Refer to figure 4 for location of connections.
1. Remove the cover from the field wiring
compartment.
2. Bring the transmitter field wiring and/or position
switch wiring into the housing through one or both of
the ports.
3. Field wiring connections:
Note
On transmitters with position
switches, always make the connection
between the power supply negative (
−
)
terminal and the (R) terminal on TB3,
even if the position switch outputs are
not used.
a. For a Type 4210, 4215, or 4220 transmitter
with position switches, connect a wire from the
(
−
) terminal of the power supply to the (R)
terminal on TB3. Also connect a wire from the (
−
)
terminal on the power supply to the negative (
−
)
terminal of the receiving device. Connect a wire
from the receiving device positive (+) terminal to
the (
−
) terminal on TB3. Connect a wire from the
(+) terminal on the power supply to the (+)
terminal on TB3. Provide wiring for the position
switch indicating device to match the application.
b. For Type 4212 and 4222 position switches
without a transmitter, connect a wire from the (+)
terminal of the power supply to the (+) terminal
on TB3. Connect a wire from the (
−
) terminal of
the power supply to the (R) terminal on TB3.
Provide wiring for the position switch indicating
device to match the application.
c. For a Type 4211 or 4221 transmitter without
position switches. Connect a wire from the (+)
terminal of the power supply to the (+) terminal
on the barrier strip (key 11). Connect a wire from
the (
−
) terminal of the power supply to the
negative (
−
) terminal of the receiving device.
Connect a wire from the receiving device positive
(+) terminal to the (
−
) terminal on the barrier strip.
4. Connect the grounding terminal (key 58) to an
earth ground.
5. For a Type 4210, 4212, 4215, 4220, or 4222
instrument with position switches, perform the
following steps to connect the position switch wiring:
a. Connect the high position switch field wiring
from the high indicating device to TB1 on the field
circuit printed wiring board.
b. Connect the low position switch field wiring
from the low indicating device to TB2 on the field
circuit printed wiring board.
6. If only one output port is used, screw the pipe
plug (supplied with the transmitter) into the unused
port.
7. Perform the potentiometer alignment and
direct/reverse action procedures for all applications.
Potentiometer Alignment
CAUTION
The following procedure must be
performed prior to calibrating the
transmitter or position switches.
Failure to perform this procedure may
result in erratic performance or unit
failure.
This procedure adjusts the potentiometer to the
center of its electrical travel when the control valve
actuator or other device is at the center of its
mechanical travel.
Refer to the Calibration section for the test
equipment required in this section.
WARNING
On an explosion-proof instrument,
remove electrical power before
removing the covers in a hazardous
area. Personal injury or property
damage may result from fire or
explosion if power is applied to the
instrument with the covers removed, in
a hazardous area.
On an intrinsically safe instrument,
current monitoring during operation
