Tighten the cap screws (key 12).
Note
The following procedure (steps 21 through 23) adjusts link 2 to ensure that it will always be in tension to eliminate possible
instability due to lost motion.
21. Disconnect link 1 from the input element, noting the hole location if the controller has a capsular input element,
and manually position the process pointer to the process scale upper limit. Tape the pointer in this position.
22. Adjust the length of link 2 by turning the adjustment screw, shown in figure 6‐10, clockwise to increase the length
or counterclockwise to decrease the length, so that the pin on the end of the link is approximately one‐half of its
diameter short of aligning with the hole in the flapper assembly, as shown in figure 6‐11.
