To align the lamp
Important! Align the lamp carefully. An excessive hot-spot
will damage optical components.
1. Switch on the MAC 550 Profile and allow it to reset.
Using either a controller or the control module, turn on
the lamp and project an open white beam on a flat
surface.
2. Center the hot spot vertically using the top Allen-head
adjustment screw in the center of the rear plate. (See
Figure 5.) If there is significant hot spot, turn the bottom
adjustment screw counterclockwise until the light is
evenly distributed. If the light is brighter around the
edge than it is in the center, or if light output is low, turn
the bottom adjustment screw clockwise until the light is
bright and evenly distributed.
