Adjusting Aiming (Pan And Tilt) - Martin Exterior Projection 500 User Manual

3. Adjust the fixture's pan angle (side-to-side beam aiming) as described later in this chapter.
Adjusting pan is best carried out with power applied to the fixture so that the projection is
visible. Once pan is correct, fasten two 12 mm (1/2 inch) shaft diameter bolts to the surface
with one bolt passing through each of the holes B. Once bolts have been installed in holes B,
pan adjustment is no longer possible.

Secondary attachment
If a secondary attachment is required for reasons of safety (in
entertainment venues, onboard marine vessels or in temporary
installations, for example), see drawing on right. Loop a safety
cable that is approved for the weight of the fixture through the
secondary attachment point (arrowed) in the fixture and attach
the safety cable to a secure anchoring point so that the cable
will catch the fixture if the primary method of attachment fails.

Adjusting aiming (pan and tilt)

Warning! The fixture can become hot. Wear heat-resistant gloves if you adjust
the aim of the fixture when it is (or has recently been) powered on.
Fixture aim adjustment is best carried out after the fixture has been
connected to power and in weak light conditions so that the
projection from the fixture is clearly visible.
See illustration on right. If you require very precise aiming and setup,
we recommend that you order the projection setup gobo available
from Martin for the Exterior Projection 500 (see 'Accessories' on
page 55) and install it in the gobo wheel while you adjust fixture aim,
focus, etc.
To adjust the aim of the fixture:
1. Set the fixture to project a setup gobo (see above) or another gobo with a sharply defined
pattern. You can select the image remotely either via DMX or by using the MANUAL TEST
menu in the fixture's control panel (see 'Manual test' on page 20).
