Adjusting Aiming (Pan And Tilt) - Martin Pro Compact Sicherheits- Und Installationshandbuch

Secondary attachment
If a secondary attachment is required for reasons of safety (in entertainment venues, onboard marine
vessels or in temporary installations, for example), you must obtain a Safety Cable Attachment
Bracket accessory from Martin by ordering P/N MAR-90590050 and install it on the fixture, then install
a safety cable that is approved for the weight of the fixture using the bracket:
1. See illustration on right. Fasten the Safety
Cable Attachment Bracket to the bottom of
the fixture in the location shown (see arrow)
using the supplied Torx screws.
2. Fasten a safety cable that is approved for
the weight of the fixture to the Safety Cable
Attachment Bracket and to a secure
anchoring point so that the cable will catch
the fixture if the primary method of
attachment fails. Remove as much slack as
possible from the safety cable (by looping it
more than once around the anchoring point,
for example). Make sure that if the primary
method of attachment fails, it will be impossible for the fixture to drop any significant distance
before the safety cable catches it.

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.
To adjust the aim of the fixture:
1. Note the 70° limit for mounting the fixture in wet conditions given under 'Mounting the fixture' on
page 29.
2. If possible, set the fixture to project a gobo with a sharply defined pattern.
3. Put on heat-resistant gloves.
4. See 'Anchoring to a surface or structure' on page 30. Loosen the bolts in the center hole A and
curved slots C of the fixture's yoke slightly, just enough to let you rotate the fixture.
5. See illustration on right. Loosen the tilt lock Allen (hex)
screws (arrowed) on both sides of the yoke slightly, just
enough to let you tilt the fixture in the yoke.
6. Pan and tilt the fixture until it is aimed correctly.
7. Use a torque driver and tighten the tilt adjustment screws on
both sides of the yoke to a torque of 9 – 10 Nm.
8. See 'Anchoring to a surface or structure' on page 30. On the
fixture's yoke, tighten the bolts in the center hole A and
curved slots C and install bolts in holes B. Check that the
fixture will be held securely in all wind and weather
conditions.
