Shaping the beam

You may shape the beam with the shutters, a pattern, an optional drop-in
iris, and/or by rotating the barrel.
Pattern projection
The pattern holder slot is on the top side of the barrel, immediately in front
of the shutters. It accommodates A-size, B-size and glass pattern holders.
Use an optional donut (model #400DN) in the accessory holder to enhance
pattern projection. Donut diameter should be 64mm to 70mm for 19º
70mm
through 50º lenses.

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. It accommodates either a drop-in iris or a
motorized pattern device. 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:
1. Use a crosshead screwdriver to loosen the screws on the drop-in iris
slot cover. Do not remove the screws.
Iris
2. Slide the cover completely forward, exposing the slot.
3. Insert the iris or motorized pattern device. If you install an 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.
Rotating the barrel assembly
1. Loosen the barrel rotation knob directly behind the shutters on the
underside of the reflector housing.
Caution: Do not remove the barrel rotation knob.
2. Rotate the barrel to the desired position (up to 25° in either direction
from centred position.)
3. Once the barrel is positioned, tighten the barrel rotation knob to lock it
into position.
