5 See Figure 6. With the nipple on the bulb facing the back,
insert the right end of the new lamp in the socket. Pull up
on the left spring and snap the other end into place.
6 Lift the lamp assembly so that lamp is level with the center
of the reflector. Push the assembly straight in until it seats,
making sure the lamp passes through the reflector opening.
Lock the 4 quarter-turn fasteners.
7 When installing a new lamp, reset the lamp hour and lamp
strike counters as described on page 14.
Aligning the lamp
1 Switch on the MAC 2000 Profile II 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.
3 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.
4 Repeat step 2.
Replacing the lamp socket
A corroded lamp socket can lead to a bad contact, causing
damage to the lamp. Damage caused by lack of maintenance of
the lamp socket is not covered under warranty.
Inspect the lamp socket each time the lamp is changed, and
replace it if its gold coating has corroded (turned a deep black
color). We recommend routine replacement of the socket after
maximum 4000 hours of use (replace one socket for every five
lamps).
