Align Lamp
The design of the VL3000 luminaire optical system allows for a flat or peaked field. A flat field is one
where there is no detectable hot spot and a peaked field is one where the intensity of the beam is
greater at the center of the beam than at the perimeter.
After a new lamp is installed, it will be necessary to align the lamp to optimize the beam. Knobs
located at the luminaire’s backcap will allow adjustment.
WARNING: Backcap and adjustment knobs will be HOT during lamp operation. Wear gloves to
prevent burns.
To align lamp:
Step
1. Power-up luminaire.
Step
2. At Menu Display, select Lamp from Config menu (refer to
“Menu Operation” on page 42
).
(If using console, set intensity to 100%, open beam size iris and focus for hard edge.)
Step
3. Position beam on a white wall at a distance of 10 to 20 feet.
Step
4. At backcap, using X, Y and Z adjustment screws, adjust beam as required.
