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.

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.
