Gobo Timing Adjustments (continued)
1)
Position index pulley so large flange is
centered in optical sensor
2)
Insert a 3" long #4 or M3 screw (or
0.125" diameter pin) completely
through aligned holes in wheels and
both bulkheads as shown. This will lock
the wheels in the "open" position.
3)
Adjust individual wheels as follows...
First align planet gear timing mark with
hole in wheel. Loosen index belt just
enough to slip teeth and rotate index
pulley to center slot in optical sensor.
Reset tension on belt and verify that
pulley slot is still centered in sensor
and sensor is centered between two
guide marks on pulley flange.
