9. Check that the goboholder is held securely. Rotate the whole gob wheel with your finger and
check that the goboholder rotates in the wheel while you rotate the gobo wheel. If the
goboholder does not rotate, it is not correctly installed and its teeth are probably not engaged
correctly in the teeth in the gobo wheel. Lift the goboholder out of the gob wheel and reinstall it
correctly.
10. Reinstall the top cover as described under ‘Removing and reinstalling the top cover’ on page
32.
Installing a glare shield accessory
A glare shield is available as an optional accessory for the Exterior Projection 500. The shield
protects from stray light and can help protect the fixture from damage caused by the sun shining
on the front of the fixture. The glare shield can be installed in seconds.
To install a glare shield:
1. See illustration below. Use a 3 mm Allen key (hex wrench) to remove the five screws (arrowed)
from the front of the fixture.
2. Fasten the glare shield securely to the fixture using the five screws as shown in the illustration.
Use a torque driver and cross-tighten to a torque of 0.7 – 1.1 Nm.
Installing a framing module
A four-blade manual framing module is available as an optional accessory for the Exterior
Projection 500. The framing module can be installed in place of the gobo module (which contains
the gobo wheel and the gobo animation wheel).
Each of the four framing blades can be manually adjusted at both ends. The module lets you form
the projection into a wide range of shapes and sizes including regular squares, trapezoid
rectangles and triangles. This lets you restrict the light output to a specific area or target – the
façade of a building, for example. Light output can be prevented from striking neighboring
buildings or dazzling pedestrians at street level, for example.
The framing effect is not intended to mask areas with sharp edges: it is not possible to obtain
sharp focus on all four framing blades simultaneously.
