2. See Figure 5. Fasten the omega
bracket to the fixture’s mounting
bracket at
A (or to the fixture housing
itself at B ) with quarter-turn fasteners.
Fastening to the mounting bracket is
preferable, as this will let you adjust
the aim of the fixture.
3. See Figure 6. Make sure that
quarter-turn fasteners are turned a full
90° to the fully locked position.
4. Block access under the work area.
Working from a stable platform, hook
the clamp over the truss chord and
tighten the clamp enough to prevent
the fixture from falling off the truss but
leave the clamp loose enough for the
fixture to hang freely.
5. If you have fastened the omega
bracket to the fixture’s mounting bracket, adjust the
orientation of the fixture to obtain the desired aiming by
loosening the tilt adjustment wheels (see Figure 1 on page
7), adjusting the aim of the fixture and retightening the tilt
adjustment wheels.
6. Keeping the fixture in the position where it is now hanging
freely, tighten the rigging clamp completely so that the
fixture is fastened securely to the truss.
7. If the fixture can fall and cause injury or damage if the
primary attachment fails, attach an approved safety cable
to a secure anchoring point and to one of the fixture’s
safety cable attachment points on the fixture (see “Fixture
overview” on page 7).
8. If you need to adjust aiming further (and if you have
fastened the omega bracket to the fixture’s mounting
bracket), loosen the rigging clamp on the truss chord slightly, loosen both tilt adjustment wheels, adjust
the position of the fixture, retighten both wheels, applying firm hand pressure only, and then retighten the
rigging clamp on the truss chord with the fixture in the position where it hangs freely.
Atomic Colors scroller
A DMX-controlled gel scroller, the Atomic Colors, is available for the Atomic 3000 LED. Your Martin supplier
can give details. See Figure 7. The scroller installs on the front of the fixture and winds different colored gels
past the front of the fixture, adding color changing to the effects that can be controlled via DMX.
