Lamp Optical Alignment
The proper focus of the luminaire occurs when the source of illumination
(lamp) is on the optical axis of the reflector. The optical alignment can be
achieved by moving the hotspot to the center of the beam using the
horizontal and vertical adjustment knobs on the lamp access plate of the
luminaire.
WARNING: Luminaire gets extremely hot. An insulated glove or #2
Philips screwdriver is recommended when making knob adjustments. If
screwdriver is to be used, alignment should be performed with luminaire at
ground level. Adjustments requiring tools should not be performed on
equipment suspended in the air.
To optically align lamp:
Step 1.
Using ACS Rack and repeater or cheater repeater, connect
luminaire to control console.
Step 2.
Apply power to luminaire and console.
Step 3.
Start lamp and allow few minutes for lamp to warm up.
Step 4.
Choose flat surface such as floor or wall onto which to direct
light beam. This makes light beam hotspot visible.
Step 5.
Focus beam on flat surface with no color and no diffusion.
Step 6.
At console, turn BEAM knob fully clockwise and EDGE knob
fully counterclockwise.
Step 7.
At luminaire rear cover, open rear door.
Step 8.
At beam adjustment knob (Figure 2-2), turn knob until hotspot
can be clearly identified.
