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
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.
before
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.

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).
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. 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.
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
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.
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.
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.
14
Instruction Manual
D200354X012
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.

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.
20
Instruction Manual
D200354X012
4200 Transmitters
October 2021
The following procedure sets the high and low position switches, and the deadband for each of them. The high
position switch must be adjusted before the low position switch. Use an ohmmeter connected between the normally
closed (NC) and common (C) connections on terminal block TB1 (high switch) or TB2 (low switch) to observe relay
switching action as directed by the procedures.
The potentiometer alignment procedures must be performed before calibrating the position switch circuits. For
transmitter and position switch switch conditions, refer to figure 7 while performing the following calibration:
1. If necessary, perform the potentiometer alignment procedure.
2. Remove power from the instrument.
3. Remove the transmitter covers. Note that you will need to loosen the set screws (key 106) before removing the
covers.
4. To provide an indication of switch conditions, remove power from the instrument. Disconnect the position switch
field wiring from TB1 and TB2, and connect an ohmmeter to TB1 between the (NC) and (C) terminals (figure 4).
Turn both the high and low deadband potentiometers (DBH, R4, and DBL, R5) fully counterclockwise to set the
deadbands to minimum and set the low position switch potentiometer (LOW, R6) fully counterclockwise.
Note
The potentiometers are 25 turn trimpots with a slip clutch. To set these potentiometers at their maximum counterclockwise
position, turn them 25 or more turns in the counterclockwise direction.
Setting the High Position Switch
For 4210, 4220, 4212, 4222, and 4215 direct acting transmitters, refer to figure 5 for location of adjustments.
1. Turn the high position switch potentiometer (HIGH, R3) fully clockwise.
2. Stroke the valve or device to the point of travel where the high position switch is to operate (see figure 7).
3. Apply power to the instrument.
4. Turn the high position switch potentiometer (R3) slowly counterclockwise until the high position switch trips, the
ohmmeter changes from a high resistance to a low resistance reading.
5. The high position switch is now set.
Setting the High Position Switch Deadband
1. Slowly stroke the actuator or device between the tripped and reset point of the high position switch. Observe this
by the changing readings of the ohmmeter. Note the differences in travel between the trip point and reset points.
This is the deadband of the switch.
2. If necessary, increase the deadband by turning the potentiometer (DBH, R4), clockwise.
3. Repeat steps 1 and 2 until the desired deadband setting is obtained.
Setting the Low Position Switch
Note
Perform the high position switch adjustment procedures before adjusting the low position switch.

3. Apply power to the instrument.
4. Ensure that the low position switch potentiometer (LOW, R6, figure 5) is fully counterclockwise as previously
instructed.
5. Turn the low position switch potentiometer (R6) slowly clockwise until the low position switch trips, the ohmmeter
changes from a high to a low resistance reading.
6. The low position switch is now set.
Instruction Manual
D200354X012
Setting the Low Position Switch Deadband
1. Slowly stroke the actuator or device between the tripped and reset point of the low position switch. Observe this by
the changing readings on the ohmmeter. Note the differences in travel between the trip point and reset points. This
is the deadband of the low position switch.
2. If necessary, increase the deadband, by turning potentiometer (DBL, R5, figure 5) clockwise.
3. Repeat steps 1 and 2 until the desired deadband setting is obtained.
4. If adjustments are complete, remove power from the instrument and disconnect the ohmmeter.
5. Perform the installation and/or operating procedures to place the transmitter in service and replace the transmitter
covers. Be sure to tighten the set screws (key 106) securely after installing the covers.
Position Switch Circuit Shutoff
Refer to figure 5 for location of adjustments.
Certain conditions may require the position switch circuit capabilities to be shut off. To shut off the position switches,
turn the high position switch potentiometer (HIGH, R3) fully clockwise, and turn the low position switch
potentiometer (LOW, R6) fully counterclockwise. To restore the position switch circuits to operation, follow the high
and low position switch adjustment procedures described in this section.
Note
Both position switch relays are energized in this condition. The trip points cannot be adjusted to prevent the relays from
energizing.
Principle of Operation
The basic concept of the electronic position transmitter can be understood by visualizing the entire transmitter as a
variable resistor in series with a load and connected to a power supply as shown in figure 9. A linkage or travel
transducer assembly transmits linear motion of the device into rotary motion of the potentiometer. The
potentiometer is connected to the input of the transmitter circuit. The voltage present at the wiper of the
potentiometer supplies input voltage to the electronic circuitry in the transmitter to produce a current output.

The position switch circuit is driven by the same input system as the transmitter (except for the 4215 transmitter). The
position switch circuit acts as an electronic switch that controls two relays. The voltage present at the wiper of the
potentiometer is compared to the settings of the high and low position switch set points and provides an on or off
condition for the relays. Instruments that use a single element potentiometer use the same element for both the
transmitter input and the input to the position switch circuits. A 4215 transmitter with dual element potentiometers
uses one element of the potentiometer for the transmitter input and the other element for the position switch circuit
input. On an instrument with position switches only, the single element potentiometer is used for the position switch
circuit input. Each of the position switch circuit outputs is connected to a relay on the field circuit printed wiring board,
and depending on the potentiometer position, the relays are energized or de‐energized.
Transmitter Circuit
At all times, the current flow into the transmitter equals the current flow out of the transmitter. The current flowing
into the transmitter divides between a regulator circuit and transistor Q1.The regulator circuit establishes two
voltages one of which is (VREF). This voltage is applied across the input potentiometer. The other voltage, (VREG)
powers the Op Amps.

4200 Transmitters
October 2021
Instruction Manual
D200354X012
On units with position switches, the transmitter voltage regulator, 4 to 20 mA signal, and relay coil currents flow in the
wire between the power supply (+) terminal and the (+) terminal on TB3. The transmitter voltage regulator, switching,
and relay coil currents are returned to the power supply common from the (R) terminal on TB3. The 4 to 20 mA output
signal flows between the (-) terminal on TB3 and the power supply common. This prevents the relay coil switching
currents from appearing on the 4 to 20 mA output.
Position Switch Circuit
A regulated voltage is setup to power the position switch circuit. The position switch circuit senses the position of the
potentiometer and triggers the appropriate position switch relay (K1 or K2, figure 10) when travel reaches the trip
points established by the adjustments. The 4215 transmitter uses dual potentiometers which allows individual
potentiometers for the transmitter circuit and the position switch circuit.

D Always wear protective clothing and eyewear when performing any maintenance operations.
D Do not remove the actuator from the valve while the valve is still pressurized.
D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the
actuator cannot suddenly open or close the valve.
D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure
on both sides of the valve.
D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.

Troubleshooting Procedures
Transmitter Circuit
Note
On transmitters with position switches, the (R) terminal on the field circuit printed wiring board must be connected to the power
supply negative (-) terminal for proper transmitter operation, even though the position switch outputs are not used.
1. Verify that the instrument is receiving power, and verify that the receiving device(s) are operating correctly.
2. If the transmitter is the problem, maintenance can be performed by either sending the entire instrument to the
factory for repair, by replacing the printed wiring board(s), or by replacing the pot/bushing assembly (key 3,
figures 11 and 14) depending on which is defective.
3. Troubleshoot the transmitter circuit by measuring the voltages.
4. Location of test voltage designated by V1 (table 6) is shown on the printed wiring board assembly (figure 12).
Table 6. Test Procedure (also refer to figure 12)
STEP
1V1TP42.46 to 2.54 VDC (VREF)
2V2TP614.1 to 16.1 VDC (+15)
3V3TP62.46 to 2.54 VDC (VREF2)
CONNECT DVM TO
(+) Lead(-) Lead
DVM READS
5. Check the voltage at V1 as described in table 6.
6. If the voltage is not present, field repair of the instrument is not recommended. Either replace the printed wiring
board or return the instrument to the factory for repair.
7. If this voltage is present, the potentiometer may be the source of trouble.
8. Check the voltage between TP3 (+) and TP4 (-) as the position of the potentiometer is varied. For 4212 and 4222
transmitters, check the voltage between TP5 and TP6 as the position of the potentiometer is varied.
a. If the voltage does not vary with position, perform the potentiometer alignment. If the problem remains, replace
the pot/bushing assembly (key 3, figure 11 or 14).
b. If the potentiometer wiper voltage checks good, but the transmitter output is constant or non‐linear, the
problem may be due to improper potentiometer alignment. Perform the potentiometer alignment procedures;
then repeat step 8 above.
c. If the potentiometer voltage is present but the transmitter output current does not change linearly as the
position of the potentiometer changes, replace the transmitter printed wiring board, or return the transmitter to
the factory for repair.
Position Switch Circuit
1. Ensure that the position switch circuit is connected correctly, and that the terminal marked (R) on the field circuit
printed wiring board is returned to the negative terminal of the supply. Refer to figure 4 for wiring connections.
2. Ensure that the power supply voltage is between 20 and 30 volts DC.

3. Check voltages V2 and V3 as described in table 6:
a. If either or both of the voltages are not present, field repair of the instrument is not recommended. Return the
instrument to the factory for repair.
b. If V2 and V3 are correct, continue with the following steps:
4. Perform the high and low position switch calibration procedures in the Calibration section.
5. If the position switches cannot be set, replace the field circuit printed wiring board (figure 11) or return the
instrument to the factory for repair.
Printed Wiring Board Removal and Replacement
WARNING
Refer to the Maintenance WARNING at the beginning of this section.
CAUTION
Electrostatic voltages present in the environment may be transferred to the transmitter printed wiring board which may
cause failure or degraded performance. Use appropriate antistatic procedures when working with the printed wiring board
to protect the electronic circuits.
