Align Lamp for Flat Field
The design of the VL2402 optical system is based on a flat field. A flat field is one
where there is no detectable hot spot.
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 and/or use tools to prevent burns.
To align lamp:
1. Using internal menus select Lamp test to set beam. See “Lamp” on page 70
for more information.(If using console, set intensity to 100% and adjust
diffusion to produce a tight beam.)
2. Position beam on a white wall at a distance of 10' to 20'.
3. At backcap, using Vertical and Horizontal knobs, adjust hot spot to center of
beam.
4. Using Focus knob adjust beam for flattest field.
