Gobo Timing Adjustments
The index timing belt must be aligned so that the mechanism "clocks" properly. This belt is installed
around the index gear (top gear) of the gobo wheel. The wheel position belt is installed around the
wheel position gear (bottom gear) of the gobo wheel, and does not require alignment. Each belt is also
routed around one motor pulley.
For the following steps, refer to Figure 2-27 and Figure 2-28 .
To time gobo wheels:
Step 1. Align all holes in wheels as shown below.
Step 2. Insert a 3" long #4 or M3 screw (or 0.125" diameter pin) completely through aligned holes
in wheel and bulkhead plates as shown. This will lock the wheels in the "open" position.

Step 3. To time Gobo Wheel 1 (VL3015 spot) or Rotating Gobo Wheel (VL3515 spot), first align
outside planet gear timing mark with notch 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.
Step 4. To time Gobo Wheel 2 (VL3015 spot only), first align outside planet gear timing mark with
mark in sun gear. Notch in wheel should be centered between opposite planet gear teeth.
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.
Step 5. To time Gobo Wheel 3 (VL3015 spot only), 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 as shown. 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.
