Fisherr 3610J and 3620J Positioners and 3622

Electro-Pneumatic Converter

Fisher 3610J or 3610JP pneumatic and 3620J or 3620JP

electro-pneumatic positioners are used in combination

with either single or double-acting rotary actuators to

accurately position control valves used in throttling

applications. The positioner mounts integrally to the

actuator housing. These rugged positioners provide a

valve position proportional to a pneumatic or a DC

current input signal.

The 3610J or 3610JP pneumatic positioner in

combination with the Fisher 3622 electro-pneumatic

converter becomes the 3620J or 3620JP positioner,

respectively. This integral electro-pneumatic

converter, can be factory installed or installed in the

field on existing positioners. The electro-pneumatic

converter receives the DC current input signal and

provides a proportional pneumatic output signal

through a nozzle/flapper arrangement.

The output signal from the converter becomes the

input signal pressure to the pneumatic positioner,

eliminating the need for a remote mounted

transducer.

The positioner mounts on the actuator as shown

below. Figure 1 shows the cam feedback mechanism

for a positioner mounted on the actuator. Positioner

bleed air continually purges the enclosure containing

the feedback lever and the feedback linkages.

To support diagnostic testing of

valve/actuator/positioner packages, connectors,

piping, and other hardware can be installed between

the 3610J or 3620J positioner and the actuator.

Features

n Accurate, Efficient, Vibration-Resistant

Operation—The positioner provides accurate,

fast-response and can withstand the vibrations of

most plant environments. Low steady-state air

consumption contributes to efficient operation.

n Modular Design— The pneumatic 3610J positioner

easily converts to an electro-pneumatic 3620J

positioner by replacing the existing gauge block

with the 3622 electro-pneumatic converter

assembly. The converter assembly attaches to the

existing positioner, providing a simple, compact,

and cost-effective conversion.

n Versatility—3610J and 3610JP positioners accept a

pneumatic input signal and 3620J and 3620JP

positioners accept a DC current input signal from a

control device. The pneumatic and

electro-pneumatic positioners provide split range

capabilities and adjustable zero and span. The

rangeability of the positioner zero and span permits

using a single range spring for all standard input

signals including split ranges.

n Fewer Spare Parts—Most of the parts for 3610J and

3610JP or 3620J and 3620JP positioners are

interchangeable, requiring fewer spare parts to

support these positioners.

n Easy Positioner Adjustments—With the cover

removed, zero, span, and cross-over adjustments,

shown in figure 2, are easily accessible and can be

made with a screwdriver.

n Application Flexibility—Easily adjustable minor loop

gain fine tunes the positioner to optimize dynamic

response for each specific actuator size and

application.

n Stable Operation—Changes in supply pressure have

minimal effect on positioner operation.

n Corrosion Resistant—Case, components, and gasket

materials withstand harsh environments. Positioner

bleed air purges internal parts and actuator housing

for additional protection.

n Field Reversible—Simple adjustments permit

switching between direct and reverse action; no

additional parts are required.

Description1

The following descriptions provide specific

information on the different positioner constructions.

3610J: A single-acting pneumatic rotary valve

positioner for use with Fisher 1051 and 1052

actuators.

3610JP: A double-acting pneumatic rotary valve

positioner for use with Fisher 1061 and 1069

actuators.

3620J: A single-acting electro-pneumatic rotary valve

positioner for use with 1051 and 1052 actuators.

3620JP: A double-acting electro-pneumatic rotary

valve positioner for use with 1061 and 1069 actuators.

3622: An electro-pneumatic converter that converts a

4-20 mA DC input signal to a 3 to 15 psig (0.2 to 1.0

bar) input signal for the pneumatic positioner.

Combining this unit with a 3610J or 3610JP positioner

produces a 3620J or 3620JP positioner, respectively.

Principle of Operation

3610J positioners accept a pneumatic input signal and

3620J positioners accept a DC current input signal

from a control device.

OUTPUT SIGNAL

These positioners are force-balanced instruments that

provide a valve shaft position proportional to the input

signal. The following describes the principle of

operation for 3610JP and 3620JP positioners. The

principle of operation for 3610J and 3620J positioners

is similar except relay A is not used. Refer to figures 3

and 4 while reading the following descriptions.

For direct action, input signal pressure from a control

device is channeled to cavity A in the input module. An

increase in input signal pressure results in a downward

force on the summing beam, pivoting the

summing beam counterclockwise. This moves the

flapper slightly toward the nozzle, increasing the

nozzle pressure. As nozzle pressure increases, the relay

beam pivots clockwise, causing relay B to increase

upper cylinder pressure and relay A to exhaust lower

cylinder pressure of the actuator.

As a result, the actuator rod extends and the actuator

rotary shaft rotates clockwise. This causes the

feedback lever to pivot clockwise and the force applied

to the summing beam by the range spring increases.

This force, which opposes the downward force on the

summing beam caused by the increasing input signal

3610J and 3620J Positioners

Product Bulletin

62.1:3610

pressure, continues to increase until the summing

beam torques are in equilibrium. At this point, the

valve shaft is in the correct position for the specific

input signal applied.

For reverse action, input signal pressure is channeled

to both cavities A and B. An increase in signal pressure

results in an upward force on the summing beam,

pivoting the summing beam clockwise and causing

relay B to exhaust upper actuator cylinder pressure to

atmosphere and relay A to increase lower actuator

cylinder pressure. As a result, the actuator rod retracts

and the actuator rotary shaft rotates

counterclockwise. This causes the feedback arm to

pivot counterclockwise reducing the force applied to

the summing beam by the range spring.

As the valve shaft rotates counterclockwise, the range

spring force to the summing beam continues to

reduce until the summing beam torques are in

equilibrium. At this point, the valve shaft is in the

correct position for the specific input signal applied.

3620J or 3620JP positioners (figure 4) are a

combination of a 3610J or a 3610JP positioner with a

3622 electro-pneumatic converter. The

electro-pneumatic converter provides a 0.2 to 1.0 bar

(3 to 15 psig) output pressure proportional to the

4-20 mA DC input signal. The 0.2 to 1.0 bar (3 to 15

psig) output pressure becomes the input signal

pressure to the 3610J or 3610JP pneumatic positioner.

Installation

The supply pressure medium must be a clean, dry, and

oil-free air, or noncorrosive gas (3610J positioners

only). If the supply pressure source is capable of

exceeding the maximum actuator operating pressure

or positioner supply pressure, appropriate steps must

be taken during installation to protect the positioner

and all connected equipment against overpressure.

Typical positioner mounting on an actuator is shown

on the front page. Overall dimensions are shown in

figure 5.

Note

3620J and 3620JP positioners are not approved for use with

natural gas as the supply medium.

3610J and 3620J positioners are available with any one

of three cams, a linear cam (cam A) or two

resultant valve rotation due to an incremental

instrument pressure change for the three cams.

Figures 7 and 8 show how the flow characteristics

change when using the cams with a valve that has

When the linear cam is the operating cam, there is a

linear relationship between an incremental instrument

pressure change and the resultant valve stem rotation.

The flow characteristic is that of the control valve.

As shown in figure 6, installing either characterized

cam as the operating cam changes the relationship

between the incremental instrument pressure change

and valve stem travel, thereby modifying the valve

flow characteristics.
