Focusing the Fixture
Once you have mounted and linked the fixtures together, you must
focus each fixture. Trackspot has a manual focus which cannot be
adjusted by a controller.
To focus the fixture:
1. Place the fixture in setup (focus) mode by setting personality
switch 2 ON.
2. Power up the fixture. The fixture performs its homing operation
and turns on the lamp. (During the homing operation you will hear
clattering sounds as the wheels, shutter, and mirror seek their
home position.)
3. Manually swivel the mirror until the beam is pointed at a flat
surface you intend to illuminate.
4. Toggle address switch 1 ON and OFF to select a gobo pattern that
helps you clearly see the effects of your focusing adjustments.
5. Loosen the lens adjustment thumbscrew and carefully slide the
lens tube in and out while watching the beam projected on the flat
surface (see Figure 2-12). When the beam has a sharp edge,
tighten the thumbscrew to secure the lens tube in place.
Caution:
You must tighten the lens adjustment
thumbscrew firmly. The lens tube may fall
from the fixture if it is not secured.
