2. It is a condition of safe use that the equipment
must be mounted in position between upward and
horizontal such that the vent is facing downwards or
horizontally.
3. It is a condition of safe use that the irrelevant
explosion protection marking codes on the
certification label are permanently scribed off upon
completion of commissioning.
Refer to table 7 for additional information, and
figure 35 for the SAA approvals nameplate.
Mounting 3610J, 3610JP, 3620J, and
3620JP Positioners
During the following mounting procedures, refer to
figure 3 for part locations. Refer to figure 28 for key
number locations unless otherwise indicated.
1. Mark the positions of the travel indicator and
actuator cover. Then, remove the actuator travel
indicator machine screws, travel indicator, and
actuator cover cap screws.
2. Remove the positioner plate from the actuator
housing.
3. For actuator styles A and D, proceed to the note
before step 7. For actuator styles B and C, continue
with step 4.
4. Disconnect the actuator turnbuckle from the lever
arm.
Do not change the position of the rod
end bearing on the end of the
turnbuckle.
5. Loosen the lever clamping bolt in the lever.
6. Mark the lever/valve shaft orientation, and
remove the lever.
Cams A, B, and C have the letter D
(direct acting) on one side and the
letter R (reverse acting) on the other
side. Always install the cam with the
letter D on the same side as the cam
mounting screw heads (key 83,
figure 3).
7. 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.
8. For actuator styles A and D, proceed to step 11.
For actuator styles B and C, continue with step 9.
9. Slide the lever/cam assembly (cam side first)
onto the valve shaft. Orient the lever with the shaft
as noted in step 6, and tighten the lever clamping
bolt.
Refer to the appropriate actuator
instruction manual to determine the
distance required between the housing
face and the lever face and to
determine the proper tightening torque
for the lever clamping bolt.
10. Connect the turnbuckle and the lever arm.
11. 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.
12. Replace the actuator cover and the travel
indicator in the positions that were marked in step 1.
CAUTION
To avoid parts damage, do not
completely stroke the actuator while
the actuator cover is removed.
To avoid personal injury from moving
parts, keep fingers and tools clear
while stroking the actuator with the
cover removed.
To aid cover alignment on 1051 and
1052 actuators, use a regulated air
source to move the actuator slightly
away from its upper travel stop. If hole
alignment is still not possible,
temporarily loosen the cap screws that
secure the housing to the mounting
yoke, and shift the housing slightly.
