Introduction
Scope of Manual
This instruction manual includes installation, operation,
calibration, maintenance, and parts ordering information for the 3582 Series pneumatic valve positioners,
the Type 3582i electro-pneumatic valve positioner,
and the 3583 Series pneumatic valve stem position
transmitters. Refer to separate instruction manuals for
information on the control valve, actuator, and accessories.
Only personnel qualified through training or experience
should install, operate, or maintain the valve positioner
or valve stem position transmitter. If there are any
questions concerning the instructions in this manual,
contact your Fisher sales office or representative before proceeding.
Description
The 3582 Series pneumatic valve positioners and the
Type 3582i electro-pneumatic valve positioner shown
in figure 1 are used with diaphragm-actuated, slidingstem control valve assemblies. The pneumatic valve
positioners receive a pneumatic input signal from a
control device and modulate the supply pressure to
the control valve actuator. The positioner adjusts the
actuator supply pressure to maintain a valve stem
position proportional to the pneumatic input signal.
Type 3582NS positioners meet typical requirements of
the nuclear power industry. The Type 3582NS
construction includes materials that provide superior
performance at elevated temperature and radiation
levels. The O-rings are EPDM (ethylene propylene)
and the diaphragms are EPDM/Nomex. EPDM
onstrates superior temperature capability and shelf life
over nitrile. The Nomex diaphragm fabric demonstrates improved strength retention at elevated temperature and radiation conditions.

Parts List
In addition, the Type 3582NS positioner is qualified
“commercial grade dedicated” under Fisher’s
10CFR50, Appendix B, quality assurance program.
These can be supplied as 10CFR21 items.
The Type 3582i is an electro-pneumatic valve positioner, consisting of a Type 582i electro-pneumatic converter installed on a Type 3582 pneumatic valve positioner. The Type 3582i valve positioner provides an
accurate valve stem position that is proportional to a
dc current input signal.
The Type 582i electro-pneumatic converter is a modular unit that can be installed at the factory or in the
field. However, do not plan to install a Type 582i converter on an existing positioner until you contact your
Fisher sales office or representative for application
assistance.
The Type 582i converter receives the dc current input
signal and, through a nozzle/flapper arrangement, provides a proportional pneumatic output signal. This
pneumatic output signal provides the input signal to
the pneumatic valve positioner, eliminating the need
for a remote-mounted transducer.
The 3583 Series pneumatic valve stem position transmitters are for use with sliding-stem diaphragm actuators. These units provide an output signal that is directly proportional to the valve stem position.
Refer to the type number description for a detailed
explanation of type numbers.

Installation
Note
All valve positioners and valve stem
position transmitters are shipped with
foam rubber packing material inside the
case. Remove the cover (key 33, figure
21) and the packing material before attempting to operate the unit. Make sure
all vent openings are clear before installation of the unit and that they remain
clear during use.
Typically, the positioner or transmitter is ordered with
the actuator. If so, the factory mounts the valve positioner or valve stem position transmitter and connects
the valve positioner output to the actuator. If a Type
67AFR filter-regulator is specified, it may be integrally
mounted to the valve positioner or valve stem position
transmitter, except for the Type 3582NS positioner.
For the Type 3582NS, the Type 67AFR is separately
mounted, not integrally mounted to the positioner.
Note
In some cases, alignment and calibra-
tion of the valve positioner or valve
stem position transmitter at the factory
may not be possible, and field align-
ment and calibration is required. Before
putting the valve positioner or valve
stem position transmitter into service,
check the operation of the unit to be
sure it is calibrated. If the valve posi-
tioner or valve stem position transmitter
requires alignment or calibration, refer
to the appropriate calibration instruc-
tions in this manual.
If the valve positioner or valve stem position transmitter is ordered separately, disconnected, or removed
from the actuator, refer to the appropriate sections of
this manual for installation information.

Mounting
Key numbers used in this procedure are shown in figure 3 except where indicated.
1. Figure 3 shows the various mounting parts required
for mounting on Fisher actuators. Mounting parts for
Fisher actuators that require spacers have the spacers
(key 50) included. Type 657 and 667 actuators, sizes
70 through 100, with or without a side-mounted handwheel, use spacers (keys 97 and 102) between the
stem connector and the connector arm (key 48). On all
other actuators that use spacers, place the spacers
(key 50) between the mounting plate (key 63) and the
actuator mounting boss.
6
Figure 3. Mounting Assembly
When mounting the valve positioner or valve stem
position transmitter on an actuator by another
manufacturer, provide spacers, if necessary, by cutting sections from 1/2- or 3/8-inch pipe so that the ‘‘X’’
dimension matches the value given in figure 6.
2. As shown in figures 3 and 4, attach the connector
arm (key 48) to the stem connector so that the connector arm extends through the yoke legs on the side
of the lower mounting boss.
3. Attach the valve positioner or valve stem position
transmitter to the mounting plate (key 63) using the
holes shown in figure 5.
4. Mount the Type 67AFR regulator:

holder and pin lock (keys 61 and 59). Place the pin
lock and holder into the slot in the connector arm (key
48). Screw the cap nut (key 62) onto the pin lock (key
59), but do not tighten.
9. With the actuator at its mid-travel position, lift the
rotary shaft arm so that the 0-degree index marks on
the rotary shaft arm are aligned with the case index
marks as shown in figure 7.
For standard travel pin setting (that is, with the
travel pin setting equal to total actuator travel). Stroke
the actuator to each end of its travel. At each end of
travel, the 30-degree index marks on the rotary shaft
arm should align with the case index marks. If the index marks are not in line, loosen the cap nut (key 62)
and slide the travel pin (key 60) in the rotary shaft arm
slot until the 30-degree index marks align with the
case index marks. Be sure the travel pin remains perpendicular to the connector arm. After making this adjustment, tighten the cap nut and re-check the arm at
the mid-travel position. If the 0-degree index marks do
CAUTION
not align, repeat this procedure.
Never set the travel pin at a setting that
is less than the actual actuator stroke.
Setting the travel pin at a setting that is
less than the actual actuator stroke will
cause the cam to rotate more than 60
degrees, causing damage to the cam or
other parts.
10. Position the travel pin so that it is perpendicular to
the connector arm and aligns with the correct actuator
stem travel index on the rotary shaft arm. Tighten the
cap nut (key 62 in figure 4).
8
For special travel pin setting (that is, with the
travel pin setting greater than total actuator travel).
Check the index marks using a procedure similar to
the standard settings procedure. The arm will not rotate a full 60 degrees as the actuator is stroked, and
the 30-degree index marks on the cam will be short of
aligning with the case index marks. If necessary, adjust the travel pin position so that the 30-degree marks
are the same distance from the respective case index
mark at each end of actuator travel.

Note
D For Valve Positioners: The small
arrow on the cam must point in the direction of stem movement with increasing actuator diaphragm pressure.
D For Valve Stem Position Transmitters: If the arrow on the cam points up
toward the nozzle, output pressure increases with downward stem movement. If the arrow points down, output
pressure decreases with downward
stem movement.
If the arrow is pointing in the wrong direction, use the following procedure to
remove, reverse, and re-install the cam.
When mounting a valve positioner or valve stem position transmitter, check to see if the correct cam (key 4)
and cam position has been selected. To change the
cam or cam position, unhook the extension spring (key
38), and remove the cam bolt and locking nut (keys 6
and 45). Remove the cam and spring retainer bracket
(key 43).
To install the cam, screw the locking nut all the way
onto the cam bolt. Attach the cam and spring retainer
bracket to the shaft assembly with the cam bolt. Tighten the bolt to secure the cam. Then, tighten the locking nut against the spring retainer bracket. Hook the
spring into the spring retainer bracket.

WARNING
Valve positioners and valve stem position transmitters are capable of providing full supply pressure to connected
equipment. To avoid personal injury and
equipment damage, make sure the supply pressure never exceeds the maximum safe working pressure of any connected equipment.

making pressure connections, turn on the supply pressure and check all connections for leaks.
Supply Connection
WARNING
Personal injury or property damage may
occur from an uncontrolled process if
the supply medium is not clean, dry, oilfree air, or non-corrosive gas. Industry
TYPE 3582
INCH
(mm)
instrument air quality standards describe acceptable dirt, oil, and moisture
content. Due to the variability in nature
of the problems these influences can
have on pneumatic equipment, Fisher
Controls has no technical basis to recommend the level of filtration equipment
required to prevent performance degradation of pneumatic equipment. A filter
or filter regulator capable of removing
particles 40 microns in diameter should
suffice for most applications. Use of
suitable filtration equipment and the establishment of a maintenance cycle to
monitor its operation is recommended.

Supply pressure must be clean, dry, oil-free
(2)
air or
noncorrosive gas. Use a Fisher Type 67AFR Filter
Regulator, or equivalent, to filter and regulate supply
air. Except for the Type 3582NS, the filter regulator
can be mounted on the positioner. For the Type
3582NS the regulator can be mounted on the mounting plate with the positioner but not on the postioner.
The supply pressure should be high enough to permit
setting the regulator 5 psi (0.3 bar) above the upper
limit of the appropriate pressure range, for example:
20 psig (1.4 bar) for a 3 to 15 psig (0.2 to 1.0 bar)
range. However, do not exceed the maximum allowable supply pressure of 50 psig (3.4 bar) nor the pressure rating of any connected equipment.
Connect the nearest suitable supply source to the
1/4-inch NPT IN connection on the filter regulator (if
furnished) or to the 1/4-inch NPT SUPPLY connection
on the positioner block assembly.
Output Connection
A factory mounted valve positioner has the valve positioner output piped to the supply connection on the
actuator. If mounting the valve positioner in the field,
connect 3/8-inch tubing between the 1/4-inch NPT
valve positioner connection marked OUTPUT and the
actuator supply pressure connection. Connect the
valve stem position transmitter connection marked
OUTPUT to an instrument that indicates valve stem
position.
Instrument Connection
For a 3582 Series pneumatic valve positioner connect
3/8-inch tubing from the control device to the 1/4-inch
NPT INSTRUMENT connection. If the control device
is mounted on the control valve assembly by the factory, this connection is made.
The Type 3582i electro-pneumatic valve positioner
requires a 4 to 20 milliampere dc current input signal
from the control device. A 1/2-inch NPT conduit connection is provided for properly wiring electrical installations. For more information, see the electrical connections section.
Diagnostic Connections
To support diagnostic testing of valve/actuator/positioner/accessory packages, special connectors and
hardware are available. The hardware used includes
1/8-inch NPT connector bodies and body protectors. If
the diagnostic connectors are ordered for a positioner
with gauges, 1/8-inch stems are also included.
Install the connectors on the 3582 block assembly or
Type 582i housing as shown in figure 9. Before installing the connectors on the positioner, apply sealant to
the threads. Sealant is provided with the diagnostic
connections and hardware.
2. Use a clean, dry, oil-free air supply with instruments containing EPDM components.
EPDM is subject to degradation when exposed to petroleum-based lubricants.

Vent
WARNING
If a flammable, toxic, or reactive gas is
to be used as the supply pressure medium, personal injury or property damage could result from fire or explosion
of accumulated gas or from contact with
toxic, or reactive gas. The positioner/actuator assembly does not form a gastight seal, and when the assembly is enclosed, a remote vent line, adequate
ventilation, and necessary safety measures should be used. A remote vent
pipe alone cannot be relied upon to remove all hazardous gas. Vent line piping should comply with local and regional codes and should be as short as
possible with adequate inside diameter
and few bends to reduce case pressure
buildup.

Electrical Connections for Type 3582i
Valve Positioner
CAUTION
When installing a remote vent pipe, take
care not to overtighten the pipe in the
vent connection. Excessive torque will
damage the threads in the connection.
The vent opening at the back of the case marked
VENT should be left open to prevent pressure buildup
inside the case and to provide a drain hole for any
moisture that might collect inside the case. A screen is
normally installed in this opening to prevent blockage
from debris or insects.
If a remote vent is required, the vent line must be as
short as possible with a minimum number of bends
and elbows. The vent connection is 3/8-inch NPT female. To connect a remote vent, press out the screen
and use 3/8-inch tubing to provide a remote vent. The
582i has a 1/4-inch NPT female vent connection.
WARNING
For explosion-proof applications, disconnect power before removing the
converter housing cap.
For explosion-proof applications, install
rigid metal conduit and a conduit seal
no more than 18 inches (457 mm) from
the converter. Personal injury or property damage might result from explosion if
the seal is not installed.
For intrinsically safe installations, refer
to the loop schematics at the end of this
manual, factory drawings, or to instructions provided by the barrier manufacturer for proper wiring and installation.
Use the 1/2-inch NPT conduit connection on the Type
582i converter housing for installation of field wiring.
For Class I, Division I explosion-proof applications,
install rigid metal conduit and a seal no more than 18
inches (457 mm) from the converter. Also, install conduit according to local and national electrical codes
which apply to the application.
Also, be certain that the exhaust holes in the relay
(key 32 in figure 21) are kept open.
