Scroller Cartridges and Beam Containment Devices

The Source Four Revolution fixture is provided with a removable scroller cartridge. You can

swap whole cartridges, or you can replace only the gel string within the cartridge. The

Scroller Cartridge also contains an accessory slot that may be used for a single standard

7.5” color frame or a beam containment device such as a top hat, half-hat or egg-crate. An

attachment point is provided on the underside of the fixture head for safety tethers on

installed beam containment devices.

C A U T I O N :

To ensure optimum pan/tilt movement, beam containment devices must not

exceed .45kg (1 pound) of weight at a center of mass 76mm (3”) from the front of

the fixture. Most standard tophats, half-hats, and egg-crates should fall into this

acceptable category. Barndoors and other heavy accessories or devices should be

avoided.

Removing and replacing the Scroller Cartridge:

Step 1:

Pull the latch on top of the scroller cartridge forward and pull the scroller up out

of the head. The gel string is held in tension and may roll back after being

released from the head.

Step 2:

To insert a scroller cartridge, align the metal tabs on the fixture with the slots on

the back of the scroller cartridge and slide the cartridge back onto the tabs.

Step 3:

Pull the latch on the top of the cartridge forward and press the cartridge down into

place.

Step 4:

Release the latch. It is spring-loaded and will slide back into the locked position

upon release.

Step 5:

Recalibrate the fixture after replacing the scroller cartridge.
