Optimizing Lamp Alignment:
This procedure centers the lamp in the
reflector. Proper optimization will increase lamp life and ensure a bright
crisp output. Improper optimization may add a yellow tint to the lamp
output and reduce intensity.
NOTE: The lamp adjustment screws
are labeled 1, 2, and 3.
1. Be sure main power is disconnected and allow the unit to cool. If
the you have just installed a new unit you can obviously skip this
step.
2. Make a preliminary adjustment: Turn the three lamp adjustment
thumb screws completely in (clockwise). Then back them each
out (counter-clockwise) about three complete turns.
3. Turn the unit on and allow it to reset.
4. Using either a DMX controller or the control panel on the unit,
strike the lamp and focus the light on a flat surface.
6. Center the hot-spot (the brightest part of the beam) using the 3
adjustment screws. Turn one screw at a time to drag the hot-spot
diagonally across the projected image. If you cannot detect a hot-
spot, adjust the lamp until the light is even.
7. To reduce a hot-spot, pull the lamp in by turning all three screws
clockwise 1/4-turn at a time until the light is evenly distributed.
8. If the light is brighter around the edge than it is in the center, or if
light output is low, the lamp is too far back in the reflector. “Push”
the lamp out by turning the screws.
