2. Fasten the safety cable to a secure anchoring point, by looping it around the truss chord, for
example. Remove as much slack as possible from the safety cable by looping it more than once
around the truss chord, for example. Then fasten the safety cable to the attachment bracket on the
fixture with the cable's carabiner clip. Make sure that the cable will catch the fixture if a primary
means of suspension fails.
Adjusting 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.
Tilt adjustment can be carried out
with the fixture powered on as
follows:
1. Put on heat-resistant gloves.
2. See illustration on right. Loosen,
but do not remove, the tilt lock
screws (arrowed) on both sides
of the yoke.
3. Tilt the fixture to the desired
angle and retighten the screws.
You can tilt the fixture up to 45°
forward or 45° backward. A scale
is printed on the yoke to ensure
accurate adjustment.
Installing a microlens beam angle accessory
Optional microlenses that modify the beam angle are available from Martin (see the Exterior Wash Pro
pages on the Martin website at www.martin.com for details and
ordering information). The following options are available:
•
Narrow (8°)
•
Medium (15°)
•
Wide (25°)
•
Very Wide (50°)'
•
Asymmetric (5 x 60°)
Note that the nominal beam angles given above are for reference
only. The effective beam angle is a combination of the nominal
microlens angle and the fixture beam angle defined by the lens.
Located close to the edge of the microlens is a marking that gives
the microlens's nominal beam angle and indicates which side of
the microlens must face outwards (see illustration on rightFigure
4). Note that the marking can be partially hidden under the
microlens's silicone gasket.
The asymmetric microlens also includes markings with arrows and beam angles indicating the
orientation of the microlens.
The microlens is held in place on the front of the fixture by the fixture's trim frame or, if installed, by a
Baffle Snoot accessory.
To install an optional microlens:
1. Shut down power to the fixture and allow it to cool.
