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
ELECTROPNEUMATIC
CONVERTER
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.

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 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 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.

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
D200064X012
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.

Characterized Cams
3610J and 3620J positioners are available with any one
of three cams, a linear cam (cam A) or two
characterized cams (cams B and C). Figure 6 shows the
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
equal percentage characteristics.
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.
