Shaping The Beam - ETC CE Source Four jr User Manual

Shaping the beam

You may shape the beam with the shutters, a pattern, or an optional
drop-in iris (ETC part #7062A1011).
Pattern projection
The pattern holder slot is on the top side of the barrel, immediately in
front of the shutters. It accommodates the M-size pattern holder
shown in Figure 7 . The M-size pattern holder's handle should bend
away from the shutter handle at a 30° angle. If your pattern holder's
handle is straight, you may bend it far enough to not interfere with the
action of the shutter handle.
Use an optional donut (ETC part #7060A1037) in the accessory holder
to enhance pattern projection.
Drop-in iris slot
The drop-in iris slot is on the top side of the front barrel, immediately in
front of the pattern holder slot. See Figure 6 . When it is not in use, a
small sheet metal cover secured with two crosshead screws prevents
light leakage and retains the iris assembly. To install an iris, follow
these steps.
Caution! Be certain the luminaire is not hot before installing the
iris.
1. Use a crosshead screwdriver to loosen the screws on the drop-in
iris slot cover. Do not remove the screws.
2. Slide the cover completely forward, exposing the slot.
3. Insert the iris. The flat side must be toward the shutters and the iris
handle should extend out of slot.
4. Slide the slot cover back toward the shutters until it meets the iris
handle. Leave enough space to move the iris handle. Tighten the
screws.
