Installation

Normally, a positioner is shipped with the actuator. If so, the factory mounts and calibrates the positioner and connects the positioner to actuator tubing. If the positioner is ordered separately from the actuator, perform the appropriate mounting procedure, and follow the Calibration procedures in this instruction manual. Refer to the appropriate instruction manuals for actuator and valve mounting procedures.

WARNING

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 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.

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.

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.

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

3610J and 3620J Positioners

September 2017

Instruction Manual

D200149X012

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

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.

Vent Connection

3610J and 3620J 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 is also 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

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).

Electrical Connection for 3620J Positioners

WARNING

Personal injury or property damage may result from fire or explosion if power is not disconnected before removing the 3622 converter cap.

For Class I, Division 1 explosion‐proof applications, install rigid metal conduit and a conduit seal no more than 457 mm (18 inches) from the 3622 converter. Personal injury or property damage may result from explosion if the seal is not installed.

For intrinsically‐safe installations, refer to the appropriate loop schematic, shown in figures 31 and 32, or to instructions provided by the barrier manufacturer for proper wiring and installation.

Select wiring and/or cable glands that are rated for the environment of use (such as hazardous area, ingress protection and temperature). Failure to use properly rated wiring and/or cable glands can result in personal injury or property damage from fire or explosion.

Wiring connections must be in accordance with local, regional, and national codes for any given hazardous area approval. Failure to follow the local, regional, and national codes could result in personal injury or property damage from fire or explosion.

Use the 1/2‐14 NPT conduit connection for field wiring installation. Refer to figures 11 and 12 when connecting field wiring from the control device to the converter. Connect the positive wire from the control device to the converter + terminal and the negative wire from the control device to the converter - terminal. Do not overtighten the terminal screws. Maximum torque is 0.45 NSm (4 lbfSin).

Calibration

The following calibration procedures are for pneumatic positioner adjustment. For 3620J, 3620JP, or 3621JP positioners, there are no adjustments within the converter portion of the positioner. All adjustments are accomplished within the pneumatic portion of the positioner.

Instruction Manual

D200149X012

3610J and 3620J Positioners

September 2017

WARNING

During calibration the valve may move. To avoid personal injury or property damage caused by the release of pressure or process fluid, provide some temporary means of control for the process.

Refer to figure 25 for key number locations. Adjustments are shown in figure 13.

Minor Loop Gain Adjustment

The minor loop gain adjustment varies the dynamic gain of the positioner to match the specific size and characteristic of the actuator. This adjustment allows tuning of the positioner transient response to the application without significantly affecting the static operating performance.

The minor loop gain adjustment is factory set for a positioner shipped with the actuator. However, additional adjustment should be made to suit the particular application requirement. The minor loop gain also may require adjustment if:

D the positioner was not installed on the actuator by the factory,

D installing the positioner on an actuator other than the type for which the positioner was originally set up,

D maintenance was performed on the positioner.

The minor loop gain should be adjusted before performing the other calibration procedures.

Figure 13 shows the minor loop gain adjustment location. As shown in figure 14, the adjustment is made by moving the flexure adjustment (key 156) along the top flexure.

The table in figure 14 and a label inside the positioner cover (key 41, figure 28) recommend flexure adjustment starting positions for various actuator types. Start with the flexure adjustment set to the recommended starting distance from the gain adjustment plate, the X dimension in figure 14. To adjust the minor loop gain, proceed as follows:

1. Unscrew the four captive cover screws and remove the cover (key 41, figure 28).

2. Refer to figures 13 and 14 and identify the gain adjustment plate, the flexure adjustment (key 156), and the X dimension between the plate and the adjustment.

3. Loosen the flexure adjustment socket head screw (key 55, figure 14) and slide the flexure adjustment on the flexures to increase or decrease the X dimension. Moving the flexure adjustment in the direction of the arrow on the top flexure (decreasing the X dimension) slows the positioner response. Moving the flexure adjustment in the opposite direction speeds up the positioner response.

4. Tighten the flexure adjustment screw and check the positioner response. Repeat step 3 if readjustment is required.

5. If this is the only adjustment, replace the cover. If not, continue with the Crossover Adjustment.

Crossover Adjustment

Perform one or the other of the following procedures, depending on the positioner and actuator type. When finished with the crossover adjustment, proceed to the zero and span adjustments.

Spring and Diaphragm Actuators (3610J or 3620J Positioners)

Note

Do not perform these steps 1 through 6 if calibrating a 3610JP, 3611JP, 3620JP, or 3621JP positioner. These 6 steps are only applicable to 3610J and 3620J positioners used on spring and diaphragm actuators.

1. Unscrew the four captive cover screws and remove the cover (key 41, figure 28).

2. If the positioner does not have pressure gauges, connect a pressure gauge to OUTPUT A.

3. Apply supply pressure.

4. Apply an input signal (pneumatic or electrical) to the positioner to position the actuator at approximately mid‐travel. If necessary, you can use the zero adjustment to position the actuator at approximately mid‐travel. The actuator should not be under load during crossover adjustment.

Note

Large step changes may cause the supply pressure gauge reading to momentarily drop.

5. Using a screwdriver, turn the crossover adjusting screw (key 13, figure 13) counterclockwise until the OUTPUT A pressure gauge reads zero pressure; then turn it clockwise until full supply pressure is obtained. Once supply pressure is obtained, turn the adjusting screw an additional four, 360‐degree turns clockwise. The gauge should read supply pressure.

6. Continue calibration by performing the zero and span adjustments.

Piston Actuators (3610JP, 3611JP, 3620JP, or 3621JP Positioners)

Note

Do not perform these steps 1 through 6 if calibrating a 3610J or 3620J positioner. These 6 steps are only applicable to 3610JP, 3611JP, 3620JP, and 3621JP positioners used on piston actuators.

1. Unscrew the four captive cover screws and remove the cover (key 41, figure 28).

2. If the positioner does not have pressure gauges, connect pressure gauges to OUTPUT A and OUTPUT B.

3. Apply supply pressure.

Note

Large step changes may cause the supply pressure gauge reading to momentarily drop.

5. Using a screwdriver, turn the crossover adjusting screw (key 13) until the sum of the OUTPUT A and OUTPUT B pressures is 140 to 160 percent of supply pressure. Clockwise rotation increases the OUTPUT A and OUTPUT B pressures.

Note

Make sure that neither the OUTPUT A pressure or the OUTPUT B pressure equal the supply pressure when adjusting the crossover screw. If either pressure is equal to supply, an accurate crossover setting cannot be achieved. This may occur with the 3611JP or 3621JP positioner due to the spring(s) in the 585, 585R, 585C, or 585CR actuator. If one of the cylinder pressures equals supply pressure when adjusting the crossover, do one or both of the following:

3610J and 3620J Positioners

September 2017

Instruction Manual

D200149X012

a. Move the actuator to some position other than mid‐travel. This new position must be in the direction which

decreases the difference between OUTPUT A and OUTPUT B (the direction which reduces compression of the actuator springs). The actuator or valve must not be contacting a stop, but must be somewhere between the up and down stops. With the lower differential between the OUTPUT A and OUTPUT B pressures, adjusting the crossover with neither the OUTPUT A pressure or OUTPUT B pressure equal to supply pressure should be possible. If not, the supply pressure must be increased.

b. Increase supply pressure noting the limitations in the Supply Connection section and repeat the cross‐over

adjustment. The actuator or valve must not contact the stop, but must be somewhere between the up and down stops. Increase supply pressure sufficiently, so that a crossover setting can be achieved with neither cylinder output pressure equal to supply pressure.

6. Continue calibration by performing the zero and span adjustments.

Zero and Span Adjustments

1. Unscrew the four captive cover screws, and remove the cover (key 41, figure 28).

2. Use tables 8 through 11 and figure 15 to select the desired range spring and coarse span adjustment. (The tables and figure 15 are only valid for the standard valve travel/range spring combinations shown.) Insert one end of the range spring (key 150, figure 25) into the hole on the range spring hanger (key 130) as shown in figure 15. Insert the other end of the range spring into the hole selected on the summing beam assembly (key 123, figure 15).

3. Apply supply pressure.

4. Apply an input signal equal to the low value of the input signal range; for example, if the input signal range is 0.2 to

1.0 bar (3 to 15 psig), apply 0.2 bar (3 psig.)

5. Rotate the zero adjustment screw (key 143, figure 13) until the actuator is at the starting point position (fully up or down depending on the action selected) corresponding to the low input signal. Clockwise rotation of the zero adjustment screw retracts the actuator stem.

6. Slowly increase the input signal toward the high end of the input signal range and observe the actuator stroke. If the actuator stroke is short of its expected range, increase the travel by rotating the fine span adjustment screw (key 128, figure 13) counterclockwise with a screwdriver. If the actuator reaches the end of its desired travel with an input signal less than the high value of the input signal range, decrease the travel by rotating the fine span adjustment screw clockwise with a screwdriver.

7. Repeat steps 4, 5, and 6 until the actuator stroke corresponds to the input signal range.

8. Replace the cover on the positioner.

Changing Positioner Action

This section explains how to change the positioner action from direct to reverse or reverse to direct. With direct action, the actuator stem extends as the input signal to the positioner increases. With reverse action, the actuator stem retracts as the input signal to the positioner increases.

September 2017

Instruction Manual

D200149X012

WARNING

Avoid personal injury or equipment damage from sudden release of process fluid and improper valve operation. Before reversing the action:

D Wear protective clothing, gloves, and eyewear whenever possible.

D Do not remove the actuator from the valve while the valve is still pressurized.

D Disconnect any operating lines providing air pressure, or a control signal to the actuator. Be sure the actuator cannot

suddenly open or close the valve.

D When disconnecting any of the pneumatic connections, natural gas, if used as the supply medium, will seep from the

unit and any connected equipment into the surrounding atmosphere. Personal injury or property damage may result from fire or explosion if appropriate preventative measures are not taken, such as adequate ventilation and the removal of any ignition sources.

D Use bypass valves or completely shut off the process to isolate the valve from process pressure.

D Vent the actuator loading pressure and disconnect positioner supply pressure.

D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.

D Check with your process or safety engineer for any additional measures that must be taken to protect against process

media.

Changing to Direct Action

1. Unscrew the four captive cover screws, and remove the cover (key 41, figure 28).

2. Loosen the reversing plate screw (key 49, figure 25), and adjust the reversing plate (key 23, figure 13) to expose the letter D and cover the letter R. Tighten the screw.

Note

Direct acting 3610J and 3620J positioners require use of the counter spring (key 125, figure 25). Reverse acting 3610J and 3620J positioners set up for 60 degree valve rotation, or reverse acting 3611JP and 3621JP positioners set up for 11 mm (7/16‐inch) actuator travel do not require use of the counter spring. Refer to the parts list for the counter spring part number to be ordered.

3. Refer to the note above to determine if a counter spring is needed. If a counter spring is required, install the counter spring (key 125, figure 25) by first removing the machine screw (key 127, figure 25), and the spring seat (key 126, figure 25). Then install the counter spring and replace the spring seat and machine screw.

4. If using characterized cam B or C, refer to the Changing Cams procedures.

5. Perform the Zero and Span adjustment procedure.

6. Replace the cover.

Changing to Reverse Action

CAUTION

Do not use bypass when the valve positioner is reverse‐acting. In this case, bypassing the valve positioner sends the input signal directly to the actuator. Such a change will affect the desired operation and possibly upset the system. Use bypass only when the input signal range is the same as the valve positioner range required for normal actuator operation.

Instruction Manual

D200149X012

3610J and 3620J Positioners

September 2017

1. Unscrew the four captive cover screws, and remove the cover (key 41, figure 28).

2. Loosen the reversing plate screw (key 49, figure 25), and adjust the reversing plate (key 23, figure 13) to expose the letter R and cover the letter D.

3. For 3610J and 3620J positioners set up for 60 degree valve rotation, or 3611JP and 3621JP positioners set up for 11 mm (7/16‐inch) actuator travel or less, a change to reverse action also requires that the counter spring (key 125, figure 25) be removed and discarded. To remove the counterspring, remove the machine screw (key 127, figure 25), the spring seat (key 126, figure 25), and the counter spring (key 125, figure 25). Then replace the spring seat and machine screw.

4. If using characterized cam B or C, refer to the Changing Cams procedures.

5. Perform the Zero and Span adjustment procedure.

6. Replace the cover.

Split‐Range Operation

CAUTION

Do not use bypass when the valve positioner is in split‐range operation. In this case, bypassing the valve positioner sends the input signal directly to the actuator. Such a change will affect the desired operation and possibly upset the system. Use bypass only when the input signal range is the same as the valve positioner range required for normal actuator operation.

Split‐range operation is possible with 3610J and 3620J positioners. With split‐range operation, the input signal from a single control device is split between two or three control valves. The positioners will fully stroke the actuator with an input signal span of 0.2 bar (3.2 psig) minimum to 2.0 bar (28.8 psig).

The zero adjustment of the positioner is continuously adjustable between 0.07 to 1.5 bar (1 and 22 psig).

Table 12 shows some typical split ranges for the positioners. Refer to tables 8 through 11 and figure 15 for the correct range spring and range spring hole selection for the desired coarse span adjustment. Contact your Emerson sales

office or Local Business Partner for input signal ranges not shown in table 12.

Note

The following is an example of range spring and range spring hole selection in tables 8 through 11. Assume a 0.2 to 0.6 bar (3 to 9 psig) input. This is equivalent to a span of 0.4 bar (6 psi) [0.6 bar - 0.2 bar = 0.4 bar (9 psig - 3 psig = 6 psi)]. Therefore for a 90 degree valve rotation and a span of 0.4 bar (6 psi), select a blue range spring. Place the range spring in hole number 2 on the summing beam assembly.

Characterized Cams for 3610J, 3610JP, 3620J, and 3620JP Positioners

3610J, 3610JP, 3620J, and 3620JP positioners are available with any one of three cams: a linear cam (cam A) and two characterized cams (cams B and C).

When the linear cam is used, there is a linear relationship between an incremental input signal change and the resultant valve rotation. The flow characteristic is that of the control valve.

When either of the characterized cams are used, the relationship between an incremental input signal change and the valve rotation is changed. Curves illustrating the relationship between the input signal and the valve rotation, and between the input signal and the flow characteristic of an equal percentage valve, are shown in figures 16, 17, and 18.

Principle of Operation

3610J positioners accept a pneumatic input signal and 3620J positioners accept a DC current input signal from a control device. 3620J electro‐pneumatic positioners use a 3622 converter to provide a pneumatic input to the pneumatic portion (3610J) of the positioner. 3610J positioners are force‐balanced instruments that provide a control valve position proportional to the pneumatic 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. The principle of operation for 3611JP and 3621JP positioners is similar except the feedback linkage does not use a cam.

Refer to the schematic diagrams as indicated:

D 3610J—figure 19

D 3610JP—figure 20

D 3611JP—figure 21

D 3620J—figure 22

D 3620JP—figure 23

D 3621JP—figure 24

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 actuator upper cylinder pressure and relay A to exhaust actuator lower cylinder pressure to atmosphere.

As a result, the actuator rod extends and the actuator rotary shaft rotates clockwise. This causes the feedback lever to pivot clockwise increasing the force applied to the summing beam by the range spring. This force, which opposes the downward force on the summing beam caused by the increasing input signal 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 input signal pressure results in an upward force on the summing beam, pivoting the summing beam clockwise and causing relay B to exhaust actuator upper cylinder pressure to atmosphere and relay A to increase actuator lower 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 on 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.

The 3620J positioner is a combination of a 3610J 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 to 20 milliampere DC input signal. The 0.2 to 1.0 bar (3 to 15 psig) output pressure becomes the input signal pressure to the 3610J pneumatic positioner.

Removing the Positioner from the Actuator

Refer to figure 28 or 29 for key number locations, unless otherwise indicated, while removing the positioner from the actuator.

1. Unscrew the four socket head screws (key 54), and remove the positioner from the actuator or positioner adaptor (key 113—the positioner adaptor is used only on selected actuator types and sizes).

2. Release all pressure to the positioner. Disconnect the supply, instrument, and output tubing.
