Mounting 3610J and 3620J Positioners on 2052 Actuators
During the following mounting procedures, refer to figure 3 for part locations. Refer to figure 28 for key number
locations unless otherwise indicated.
1. Remove the actuator cover plate from the actuator housing.
Note
Cams A, B, and C have the letter D (direct acting) on one side. Always install the cam with the letter D on the same side as the cam
mounting screw heads (key 83, figure 3).
2. Install the desired cam (key 82) on the actuator lever with the cam mounting screws (key 83). Cams B and C use the
cam adjustment indicator (key 84) between the screw heads and the cam. Align the cam adjustment indicator with
the desired total valve rotation indication on the cam. Cam A does not use the cam adjustment indicator and does
not require adjustment.
3. Remove the positioner cover (key 41) from the positioner. Slide the positioner into the actuator housing so the cam
roller (key 39) rests on the cam. Insert and tighten the socket head screws (key 54) to secure the positioner to the
actuator housing.
4. Replace the positioner cover (key 41) on positioner.
CAUTION
To avoid parts damage, do not completely stroke the actuator while the actuator cover is removed.
WARNING
To avoid personal injury from moving parts, keep fingers and tools clear while stroking the actuator with the cover
removed.
Note
The travel stop for 1051 and 1052 actuators are different for 2052 acuators. Refer to the appropriate instruction manual for 1051
and 1052 actuator mounting details.
