Introduction
Scope of Manual
This instruction manual provides installation, operating, calibration, maintenance, and parts ordering information for
Fisher 4200 electronic position transmitters (figure 1). Refer to separate instruction manuals for information on the
actuator and valve.
Do not install, operate, or maintain a 4200 electronic position transmitter without being fully trained
and qualified in valve, actuator, and accessory installation, operation, and maintenance. To avoid
personal injury or property damage, it is important to carefully read, understand, and follow all of the
contents of this manual, including all safety cautions and warnings. If you have any questions regarding
these instructions contact your Emerson sales office before proceeding.
Description
4200 electronic position transmitters combine Fisher field‐proven electronic and mechanical expertise in a versatile,
accurate instrument. They sense the position of a sliding‐stem actuator, rotary actuator, vent, damper, or other device
and send a standard (4‐20 mA) output signal to an indicating device, a process control system or programmable logic
controller. 4200 transmitters are available as a transmitter only, as a transmitter with integral high and low position
switches, or with high and low position switches only. Refer to the nameplate to determine the type of transmitter.
Use the Type number and table 2 to determine the output and travel ranges available from the transmitter.
When the instrument is mounted, the potentiometer shaft (figure 2) is mechanically connected to the device to sense
mechanical motion. Except for the 4215 transmitter, all types of transmitters use a single potentiometer for position
input. The 4215 transmitter uses dual potentiometers mounted on the same shaft. This permits using individual
potentiometers for the transmitter and the position switch circuits, providing additional electrical isolation. For
long‐stroke applications, a multi‐turn potentiometer attached to a travel transducer assembly senses linear motion of
the actuator stem or other device.

1. Zero position is the range of values over which the transmitter zero can be adjusted. Span is the range of shaft rotation or stem travel the transmitter span can be adjusted. For example, a zero
position of 45 degrees and a span of 15 degrees means the transmitter output is 4 mA DC after 45 degrees of shaft rotation. The output then increases from 4 mA DC to 20 mA DC as the shaft
rotates from 45 to 60 degrees.

Installation
WARNING
Always wear protective clothing and eyewear when performing any installation operations to avoid personal injury or
property damage.
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.

DC power supply independent of the receiving device is recommended. A separate return is required for the relays.
This prevents relay return currents from flowing in the transmitter 4 to 20 milliamperes DC current loop.
For the position switch relay wiring, during normal operating conditions relays K1 and K2 are energized, which
connects the common (C) terminal to the normally open (NO) terminal (TB1 and TB2, figure 4). During a tripped (or
alarm) condition the relay is de‐energized, which connects the C terminal to the normally closed (NC) terminal. If
power is removed or lost from the power supply both relays are de‐energized which connects the common (C)
terminals to the normally closed terminals (NC).
NOTICE
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. Note that you will need to loosen the set screw (key 106)
before removing the cover.
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 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 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 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 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.

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
NOTICE
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
Do not remove the covers on explosion-proof instruments when an explosive atmosphere is present. Personal injury or
property damage may result from fire or explosion if covers are removed in an explosive atmosphere.
WARNING
When monitoring current during operation of an intrinsically safe instrument in an intrinsically safe area, a meter approved
for hazardous areas must be used. Personal injury or property damage may result from fire or explosion if an approved
meter is not used in a hazardous area.
Refer to figure 5 for component locations.
1. Remove power from the instrument.
2. Connect the digital voltmeter (DVM) leads as follows:
a. For all transmitters (except a 4212 or 4222) connect between TP3 (+) and TP4 (-) on the printed wiring board.
b. For a 4212 or 4222 transmitter, connect the DVM between TP5 (+) and TP6 (-).
3. Loosen the appropriate set screw connecting the potentiometer shaft to the linkage:
a. For sliding‐stem applications, loosen the set screw (key 26, figure 15) in the operating arm (key 30) on the
potentiometer shaft.
b. For rotary actuator applications, loosen the set screw in the coupling (key 50, figure 19) on the potentiometer
shaft.
c. For long‐stroke applications, leave the coupler (key 100E) rigidly attached to the potentiometer shaft. Loosen
only the coupling screw (key 100F, figures 22 and 23) in the coupler (key 100E) on the transducer shaft.
4. Stroke the actuator or other device to the mid‐stroke position.
Note
On units with position switches, the (R) terminal on TB3 must be connected to the power supply negative (-) terminal as shown in
figure 9 to attain correct potentiometer alignment.

5. Apply power to the instrument.
6. While the device is in mid‐stroke position, insert a screwdriver blade into the slot in the end of the potentiometer
shaft (see figure 15), or turn the coupler (key 52, figure 19 or key 100E, figures 22 and 23) to turn the
potentiometer shaft until the DVM reads 1.25 ±0.05 volts DC. This establishes the electrical center of the
potentiometer.
7. Tighten the appropriate set screw. Check that the DVM reading has remained at 1.25 ±0.05 volts DC.
Note
For sliding‐stem applications, tighten the set screw (key 26, figure 15) in the operating arm (key 30) to a torque of 3.39 to
3.95 NSm (30 to 35 lbfSin).
8. Remove the power from the transmitter power supply.
9. Remove the DVM leads from TP3 and TP4 (transmitter signal) or TP5 and TP6 (position switch signal).
10. Refer to the direct or reverse action procedures.
Direct or Reverse Action
Direct action means, when looking at the slotted end of the potentiometer shaft, a clockwise rotation of the shaft
produces an increasing output signal from the transmitter.
Reverse action means, when looking at the slotted end of the potentiometer shaft, a clockwise rotation of the shaft
produces a decreasing output signal from the transmitter.
The transmitter produces a direct or reverse action output signal depending on the location of the potentiometer
wires inserted in terminal block number 1 (TB1) mounted on the transmitter printed wiring board. Refer to figure 6 for
the location of the wires and the wire color sequence for direct action.

Instruction Manual
D200354X012
4200 Transmitters

For reverse action, exchange the positions of the brown and red wires.
Arrange wires on the terminal block (TB1) for either direct or reverse action to match the application requirements;
then repeat the potentiometer alignment procedures.
Refer to the Calibration section to adjust the zero and span of the transmitter and/or position switch circuits.
Operating Information
Initial Considerations
If the transmitter is ordered with an actuator, the transmitter is factory calibrated to the length of travel specified on
the order. If the transmitter is ordered separately, adjust the zero and span as described in the Calibration section so
that the transmitter operates properly in your specific application.
If the transmitter is calibrated for a specific control valve actuator travel, perform the procedures in the Calibration
section to fine tune the zero and span adjustments to the specific application.
Transmitter and Position Switch Conditions
D A 4210 or 4220 transmitter (with position switches) obtains stem position from the input potentiometer and circuit
electronics to provide a 4 to 20 milliampere output. The transmitter output connects to a terminal block mounted
in the field wiring compartment. The high position switch circuit output controls relay K1 mounted on the field
circuit printed wiring board, and the relay contacts connect to TB1. The low position switch circuit output controls
relay K2, and the relay contacts connect to TB2. The relationship between the transmitter output, relay position
switch outputs, and deadband is shown in figure 7. Deadband is the difference between trip and reset points of a
relay.
D A 4211 or 4221 transmitter (without position switches) obtains input information from the potentiometer and
provides a 4 to 20 milliampere output. The transmitter output connects to the barrier strip (key 11, figure 4)
mounted in the field wiring compartment.
D A 4212 or 4222 position switch (without the transmitter) obtains stem position from the input potentiometer and
provides position switch outputs from relays K1 and K2 (figures 4 and 9). The high position switch circuit output
controls relay K1 mounted on the field circuit printed wiring board and, the relay contacts connect to TB1. The low
position switch circuit output controls relay K2 and, the relay contacts connect to TB2. Deadband is the difference
between trip and reset points of a relay.
D A 4215 transmitter obtains position information from a dual potentiometer on the same shaft, which allows for
individual potentiometers for the transmitter circuit and the position switch circuits. The transmitter input is from
one of the potentiometers and its output connects to TB3 (figure 6) mounted on the field circuit printed wiring
board. The position switch input is obtained from the other potentiometer.
The high position switch circuit output controls relay K1 mounted on the field circuit printed wiring board and the
relay contacts connect to TB1. The low position switch circuit output controls relay K2 and the relay contacts connect
to TB2. The relationship between the transmitter output, relay position switch outputs, and deadband is shown in
figure 7. Deadband is the difference between the trip and reset points of a relay.

4211, 4215, 4220, or 4221 transmitter. On 4212 or 4222 connect a voltmeter between TP5 (+) and TP6 (-) to measure
potentiometer position.
Note
You will need to loosen the set screw (key 106) before removing the cover.
For position switch circuits, the switching condition can be monitored by observing the indicating device or using an
ohmmeter connected to the terminal blocks (TB1 and TB2) in the field wiring compartment. Refer to the Calibration
section for the test setup.
Calibration
Note
The potentiometer alignment procedures, in the Installation section, must be completed before performing instrument
calibration. Also, be sure the direct or reverse action is correct for the application.
Calibration of the instrument consists of adjusting the zero and span of the transmitter and/or adjusting the high and
low position switches for a specific travel. The high and low position switches also have deadband adjustments that are
made during the calibration procedures. Refer to figure 7 for transmitter and position switch conditions.
For a 4212 or 4222 instrument with position switch circuits only, refer to the high and low position switch adjustment
procedures in this section. For a transmitter with or without position switch circuits, refer to the transmitter circuit
zero and span adjustment procedures in this section.
If satisfactory results cannot be obtained during calibration, refer to the appropriate procedures in the Maintenance
section.

Test Connections to the Field Wiring Compartment
During calibration set up the transmitter as shown in figure 8. Except for 4211 and 4221 transmitters, the field circuit
printed wiring board is used. A 4211 or 4221 transmitter uses a barrier strip (key 11, figure 4) mounted in the field
wiring compartment for field wiring connections. For calibration and bench check of the 4211 or 4221 transmitter,
make connections to the barrier strip (key 11).
For a 4210, 4215, or 4220 transmitter with position switches, the transmitter can be calibrated with or without the
position switch outputs being connected.
Note
On units with position switches, the (R) terminal on TB3 must be connected to the power supply negative (-) terminal for proper
instrument operation, even if the position switch outputs are not used.
For a 4211 or 4221 transmitter without position switches, use a two wire system with the indicating device installed as
shown in figure 8.

Transmitter Circuit Zero and Span Adjustment
WARNING
On an intrinsically safe instrument, the current monitoring across TP1 and TP2 during operation must be with an approved
meter. Personal injury or property damage may result from fire or explosion if an approved meter is not used in a
hazardous area.
Calibration of the transmitter consists of adjusting the zero and span for a 1 to 5 volt DC output across a 250 ohm
resistor, or a 4 to 20 mA output current for a specific travel. If necessary refer to the type number on the nameplate to
determine the configuration of the transmitter.
1. Remove power from the instrument.
2. Connect the transmitter as shown in figure 8.
3. Remove the transmitter covers. Note that you will need to loosen the set screws (key 106) before removing the
covers.
4. Stroke the valve or device to the mid‐stroke position
5. Check the potentiometer alignment by connecting a digital voltmeter (DVM) as follows:
a. For all transmitters (except a 4212 or 4222) connect between TP3 (+) and TP4 (-) on the printed wiring board.
b. For a 4212 or 4222 transmitter, connect the DVM between TP5 (+) and TP6 (-).
6. Apply power to the instrument.
7. The DVM should read 1.25 ±0.05 volts DC. If not, perform the potentiometer alignment procedures in the
Installation section.
8. Stroke the valve or device to the point of travel where the transmitter output is to be 4 milliamperes DC.
9. Adjust the zero potentiometer (R1, figure 5) until the output is 4 milliamperes DC (1.00 volt across 250 ohms).
10. Stroke the valve or device to the point of travel where the transmitter output is to be 20 milliamperes DC.
11. Adjust the span potentiometer (R2, figure 5) until the output is 20 milliamperes DC (5.00 volts across 250 ohms).
12. Some small interaction between the two adjustments may occur. Repeat steps 8 through 11 until the error is within
the application requirements.
13. For a 4211 or 4221 transmitter without position switches, calibration is complete. Refer to the installation and/or
operating information to place the transmitter in service.
14. If calibration is complete, replace the transmitter covers. Be sure to tighten the set screws (key 106) securely after
installing the covers. For transmitters with position switches, refer to the high and low position switch adjustment
procedure below.
High and Low Position Switch Adjustment
Note
The “high” and “low” designations refer to the voltage output of the position potentiometer. See figure 7 for relationship to valve
or actuator travel.
The high position switch must be adjusted before the low position switch. If the deadband of either the high or low position
switches exceeds the difference between the set points of the high and low position switches, both position switches may be on at
the same time.
