Avoid personal injury from sudden release of process pressure. Before mounting the positioner:
D Always wear protective clothing gloves, and eyewear when performing any installation operations to avoid personal
injury.
D When installing 3620J, 3620JP, and 3621JP positioners in a hazardous area, turn off control signals until installation is
complete. Be sure all safety barriers, connections, and the converter housing cap and O‐ring are properly installed
before applying a control signal to the unit.
D If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
WARNING
Personal injury or property damage may result from fire or explosion if natural gas is used as the supply medium and
appropriate preventive measures are not taken. Preventive measures may include, but are not limited to, one or more of
the following: Remote venting of the unit, re‐evaluating the hazardous area classification, ensuring adequate ventilation,
and the removal of any ignition sources.
3620J, 3620JP, 3621JP positioners and the 3622 electro‐pneumatic converter do not meet third party approvals for use with

Installing the 3622 Electro‐Pneumatic Converter
If installing the converter on an existing pneumatic positioner, refer to the Gauge Block Disassembly 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 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.
CAUTION
Do not use sealing tape on pneumatic connections. This instrument contains small passages that may become obstructed
by detached sealing tape. Thread sealant paste should be used to seal and lubricate pneumatic threaded connections.

3610J and 3620J Positioners
September 2017
18
To complete the installation of a 3610J or 3620J positioner requires connecting tubing and fittings between the
positioner and the actuator. The fittings, tubing, and mounting parts required depend on the type number and
optional equipment: such as filter, regulator, and bypass valve. Positioner pressure connection locations are shown in
figure 8. All pressure connections to the 3610J and 3620J positioners are 1/4 NPT internal. Use 3/8‐inch tubing or
1/4‐inch pipe for all tubing connections. Refer to the Vent Connection section for remote vent connections.
Supply Connection
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, and noncorrosive gas. While use and regular maintenance of a filter that removes particles larger
than 40 micrometers in diameter will suffice in most applications, check with an Emerson Automation Solutions 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 with standard 5
micrometer filter, 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.
