Mounting 3611Jp And 3621Jp Positioners On 585C And 585Cr Actuators - Emerson Fisher 3610J Instruction Manual

Instruction Manual
D200149X012
10. With the actuator still at mid‐travel and the top edge of the feedback lever assembly perpendicular to the actuator
stem, install the adjuster assembly/roller in the appropriate stem bracket slot with the button head screw (key 173)
so the roller is centered over the correct actuator travel marked on the feedback lever assembly (key 170) as shown
in figure 4.
11. Tighten the button head screw (key 173) and replace the range spring (key 150, figure 25).
12. For size 100 actuators with greater than a 51 mm (2 inch) travel, install the feedback lever spring (key 185).
13. Replace the positioner cover.
14. Replace the front actuator cover plate.
15. Discard the actuator blanking plate and the four screws.
Mounting 3611JP and 3621JP on 585C and 585CR Size 25 and 50
Actuators
The 3611JP pneumatic positioner and the 3621JP electro‐pneumatic positioner can be mounted on either a 585C or
585CR piston actuator. A positioner adaptor (key 113) attaches to the back of the positioner and serves as the
interface to the mounting bracket (key 194). Refer to the 585C and 585CR actuators instruction manual
(D102087X012) for additional information on the actuator.
Refer to figure 5 for parts identification.
1. Stroke the actuator from the top stop to the bottom stop, and record the travel distance.
2. Loosen the four captive cover screws and remove the positioner cover (key 41, figure 28).
3. Mount the stem bracket (key 195) to the actuator with two hex nuts (key 197).
4. Disconnect the positioner range spring (key 150, figure 25) from the range spring hanger (key 130, figure 25).
5. Attach the feedback roller (key 175) to the stem bracket (key 195) with the button head screw (key 173).
6. Attach the positioner adaptor (key 113) to the mounting bracket (key 194) with four hex nuts (key 197) and four
hex socket cap screws (key 54).
7. Remove the positioner cover. Attach the 3611JP or 3621JP positioner to the positioner adaptor/mounting bracket
assembly with four hex socket cap screws (key 54).
8. Apply pressure to the actuator piston and move the actuator to approximately the mid‐travel position.
9. Thread one of the three hex head cap screws (key 196) into the yoke leg threaded hole approximately two (2) turns.
10. Install the assembly from step 7 to the 585C or 585CR actuator by sliding the mounting bracket slot (see figure 6)
onto the yoke leg cap screw. As you attach this assembly to the actuator, center the spring‐loaded feedback arm
under the feedback roller (key 175) on the stem bracket (key 195). Align the mounting bracket top holes (see
figure 6) with the cylinder holes and install the remaining two hex head cap screws (key 196). Tighten all screws.
11. With the actuator still at mid travel and the top edge of the feedback lever assembly perpendicular to the actuator
stem, install the adjuster assembly/roller in the appropriate stem bracket slot with the button head screw (key 173)
so the roller (key 175) is centered over the correct actuator travel marked on the feedback lever assembly.
12. Tighten the feedback roller button head screw (key 173) and replace the range spring (key 150, figure 25).
13. Replace the positioner cover.
