procedures in the Maintenance section. The
converter module replaces the original pneumatic
gauge block. Refer to the 3622 Electro-pneumatic
Converter Assembly procedure to install the
converter. When calibrating the electro-pneumatic
positioner for a 4 to 20 milliampere DC input range,
use the range spring hole that corresponds to a 0.2
to 1.0 bar (3 to 15 psig) input range [0.8 bar (12
psig) span]. See tables 10 and 11 and figure 15 for
the range spring and range spring hole selection.
Changing Positioner Types
All 3610J and 3620J Series positioners have the
same basic construction. For 3611JP or 3621JP, a
parallel flexure (key 179, figure 13) is added (not
required on 585 size 100 actuator). When changing
positioner types, other parts may require changing,
such as the nozzle assembly (key 116, figure 25),
the feedback lever assembly (key 117 or 170, figure
29), and the range spring (key 150, figure 25). Refer
to the Parts List for part number identification.
Changing parts may require partial disassembly and
reassembly as described in the Maintenance
section. Figure 7 illustrates the slight difference in
nozzle assemblies between the single-acting (3610J
and 3620J) and double-acting (3610JP, 3620JP,
3611JP and 3621JP) positioners. See the Changing
Positioner Types procedure in the Maintenance
section for additional information.
Pressure Connections
WARNING
The positioner is capable of providing
full supply pressure to connected
equipment. To avoid personal injury or
equipment damage caused by parts
bursting from system overpressure,
make sure the supply pressure never
exceeds the maximum safe working
pressure of any connected equipment.

WARNING
Severe personal injury or property
damage may occur from process
instability if the instrument supply
medium is not clean, dry and oil-free
air, or noncorrosive gas. While use
and regular maintenance of a filter that
removes particles larger than 40
microns in diameter will suffice in
most applications, check with an
Emerson Process Management field
office and industry instrument air
quality standards for use with
corrosive gas or if you are unsure
about the proper amount or method of
air filtration or filter maintenance.
WARNING
3620J, 3620JP, 3621JP positioners and
the 3622 electro-pneumatic converter
do not meet third party approvals for
use with natural gas as the supply

medium. Use of natural gas as the
supply medium can result in personal
injury or property damage from fire or
explosion.
Supply pressure must be clean, dry, and oil-free air
or noncorrosive gas. Use of a 67CFR Filter
Regulator, or equivalent, to filter and regulate supply
air should suffice in most applications. The 67CFR
filter regulator can be integrally mounted with the
positioner. Use 3/8-inch tubing or 1/4-inch pipe for
the supply line.
CAUTION
To avoid equipment damage caused
by excessive pressure, do not exceed
the maximum pressure rating of the
actuator or positioner. Refer to the
appropriate instruction manual to
determine the maximum pressure
rating of the actuator, and to table 1
for the maximum pressure rating of the
positioner.
The supply pressure should be high enough to
permit setting the regulator 0.3 bar (5 psi) above the
upper limit of the appropriate pressure range, for
example: 1.4 bar (20 psig) for a 0.2 to 1.0 bar (3 to
15 psig) range. However, do not exceed the
maximum allowable supply pressure of 10.3 bar
(150 psig) nor the pressure rating of any connected
equipment.
Output Connections
For the 3610J or 3620J positioner, the OUTPUT A
connection must be plugged. Connect the OUTPUT
B connection to the actuator diaphragm casing

connection. Figure 8 shows a positioner with a
bypass valve. When the bypass valve is used,
connect the OUTPUT connection on the bypass
valve to the diaphragm casing connection on the
actuator. A manifold in the bypass body adapter
internally connects OUTPUT B to the bypass valve.
Use 3/8-inch tubing between the actuator and the
positioner.
For the 3610JP or 3620JP positioner, connect the
OUTPUT A connection to the lower actuator cylinder
connection and the OUTPUT B connection to the
upper actuator cylinder connection. Figure 1 shows
the positioner connected to a piston actuator. Use
3/8-inch tubing between the actuator and positioner.
For the 3611JP or 3621JP positioner, connect the
OUTPUT A connection to the lower actuator cylinder
connection and the OUTPUT B connection to the
upper actuator cylinder connection. Figure 2 shows
the positioner connected to a 585C actuator. Use
3/8-inch tubing between the actuator and the
positioner.
Instrument Connection
Use 3/8-inch tubing to connect the output from the
control device to the INSTRUMENT connection on a
pneumatic positioner. For the electro-pneumatic
positioner, refer to 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 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 3610J Series positioner
gauge block or bypass block assembly as shown in
figure 9. For 3620J Series positioners, install the
connectors on the 3622 housing as shown in figure
10. Before installing the connectors on the
positioner, apply sealant to the threads. Sealant is
provided with the diagnostic connections and
hardware.
Vent Connection
3610J and 3620J Series positioner relays exhaust
actuator pressure through the positioner case and
into the 1051, 1052, 1061, and 1069 actuator
housings. These actuator housings provide a 1/4
NPT connection and a screen is normally installed in
this connection to prevent blockage from debris or
insects. Restricting this vent area can produce a
pressure buildup in the case and degrade positioner
performance. There also is a 1/4 NPT connection on
the 3622 converter housing where the vent (key 28)
is installed. 585, 585R, 585C, and 585CR actuators
do not have a 1/4-inch vent connection.

WARNING
Personal injury or property damage
could result from fire or explosion of
accumulated gas if a flammable gas is
used as the supply pressure medium
and the positioner/actuator is in an
enclosed area. The positioner/actuator
assembly does not form a gas-tight
seal, and a remote vent line is
recommended. However, a remote vent
line cannot be relied upon to remove
all hazardous gas, and leaks may still
occur. Provide adequate ventilation
and necessary safety measures. 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.
WARNING
3620J, 3620JP, 3621JP positioners and
the 3622 electro-pneumatic converter
do not meet third party approvals for
use with natural gas as the supply
medium. Use of natural gas as the
supply medium can result in personal
injury or property damage from fire or
explosion.
If a remote vent is required, the vent line must be as
short as possible with a minimum number of bends
and elbows. Vent line piping should have a minimum
inside diameter of 19 mm (3/4 inches) for runs up to
6.1 m (20 feet) and a minimum inside diameter of 25
mm (1 inch) for runs from 6.1 to 30.5 meters (20 to
100 feet).
