Replacing a rotating gobo
Important: Different screw sizes and types are used on the modules and components inside the head.
Make sure that you do not mix them up. Apply a small quantity of Loctite 222 to the threads of all the screws
mentioned in this section when you reinstall them.
To replace a rotating gobo:
1. Remove both head covers as described in the previous section.
2. See Figure 11. Position the head so that the effects cooling fan A is facing you. You are now looking at
the bottom of the head.
3. Unplug the effects fan connector B, remove and keep the fan’s two retaining screws C and remove the
fan from the head.
4. See Figure 12. Locate the effects module connector (arrowed) and disconnect it from the PCB on the left
of the head. Let the connector and wireset hang free.
