Replacing Gobos and Filters

The Static Wheel Module and the Rotating Wheel Module both use the same gobo/filter

retention method. In each case, the gobo/filter is secured with a spring.

Replace a gobo/filter:

Step 1:

Power-down the fixture. See

Step 2:

Remove the module from the fixture. See

C A U T I O N :

Screws securing the modules, and the wheels themselves, may be hot if the fixture

has recently been lit. Allow the module to cool before installing gobos or filters.

Step 3:

Remove the spring securing the gobo/filter you want to replace or install. Use the

diagram below to determine the frame numbers on each wheel. In newer

modules, notches have been cut into the wheel close to the positions, indicating

the position’s number. In older modules, these notches do not exist. If you have

an older module, use the diagram below to find the position number.
•

Magnets are found in the alignment holes for frame #3 in each wheel. The

Rotating Wheel Module has two magnets, one for calibrating the wheel

position, and one for calibrating the index position of the frames.

Step 4:

Remove the gobo/filter, if present.

Step 5:

Insert the new gobo/filter in the frame. Use the hole in or near the frame (see

below for alignment hole locations) to align your gobo, if required.

C A U T I O N :

To prevent cracking of glass gobos and for best image contrast, the silver reflective

surface of the gobo must face the lamp and the black surface of the gobo must face

the lenses. Prolonged use of the Rotating Wheel Module in the Rear Bay may

cause the belt within the module to degrade. To ensure peak performance of the

RWM, use it in the Front Bay.
