3610J and 3620J Positioners
only), and 185 [585 actuator, size 51- through
102-mm (100 with 2- through 4-inch) travels only,
see figure 29].
5. Changing from a 3610J to a 3611JP or a 3620J
to a 3621JP requires installing a parallel flexure (key
179, figure 25). The parallel flexure is not used on
positioners for 585 size 100 actuators. Earlier
3611JP positioners do not have this part. Therefore,
the summing beam assembly (key 123, figure 25) or
relay assembly (key 122, figure 25) or both may be
required if they are not drilled and tapped to accept
this parallel flexure. The following parts are required:
keys 179, 180, and 181, figure 25.
6. Changing from a 3610J to a 3611JP or a 3620JP
to a 3621JP may require a positioner adaptor (key
113, figure 28). Use four socket head screws (key
54, figure 28) to mount the adaptor.
7. Changing from a 3611JP to a 3610J or a 3621JP
to a 3620J requires the following feedback parts:
keys 38, 39, and 60 in figure 28.
8. Changing from a 3611JP to a 3610J or a 3621JP
to a 3620J, requires a cam (key 82, figure 28).
Mount the cam with two screws (key 83, figure 28)
and a cam adjustment indicator (key 84, used only
with characterized cams B or C, figure 28). Refer to
the Mounting 3610J, 3610JP, 3620J, and 3620JP
Positioners procedures for correct cam mounting.
9. Changing from a 3611JP to a 3610J or a 3621JP
to a 3620J requires a pipe plug (key 78, figure 26) to
plug output A. Apply sealant (key 154) to the threads
of the pipe plug.
10. The range spring (key 150, figure 25) may need
to be changed depending on actuator type and size.
Refer to tables 8 through 11 for range spring
selection and hole position on the summing beam
assembly for coarse span adjustment.
