Temporarily install the mounting bracket at 90° from normal (see Figure 12)
so that the adjustment hole is accessible.
5.
Put the clamp ring back on and attach the valve or valve/standoff assembly.
Plug in the actuator power cord and align the valve as nearly as possible, as
described in Section 5.4, Alignment Procedure.
6.
Unplug the power cord.
7.
Use a 7/64 hex driver to loosen the 6-32 cap
screw on the gearshaft crank. (Figure 14)
8.
Use a screwdriver to
slightly
move the gearshaft
crank pin. (Figure 15) To
increase
the stroke,
rotate it slightly (1/16 turn) in the direction which
has the most resistance. To
decrease
the stroke,
rotate it in the direction which has the least resis-
tance.
9.
Lock the 6-32 cap screw on the gearshaft.
10. Plug in the power cord. Cycle the valve several times and check the
alignment. If the valve rotation is still incorrect, loosen the gear shaft crank
screw and readjust the gear shaft crank pin to set rotation correctly.
11. When the rotation is correct, unplug the power cord and reassemble the
electric actuator and valve with all the parts in proper orientation.
12. Realign the valve as described in Section 5.4, Alignment Procedure.
