The RoboScan Pro 518 comes fully adjusted from the factory, however, readjustment of the
lamp may be necessary due to differences between lamps. The lamp is adjusted by turning
the 3 Phillips-head screws on the lamp access plate. Turning these clockwise pulls the lamp
back towards the rear and vice versa. Keep adjustments small to avoid pulling the lamp so
far off center that it hits the reflector.
W A R N I N G !
The fixture must be cool and disconnected from AC power.
1. Remove the 3 thumbscrews from the lamp access plate and remove the lamp
assembly.
2. Make a preliminary adjustment: turn the adjustment screws so that the
inside-to-inside measurement between the lamp socket mounting plate
and the lamp access plate is 13 mm (1/2 in). Replace the lamp assembly.
3. Flip DIP-switch pins 8 and 10 on. Flip all other pins off.
4.
Apply power to the RoboScan Pro 518. After it has reset, it produces a
white light with an open gobo for adjustment purposes. Wait approxi-
mately 5 minutes for the lamp to reach full brightness.
5. Manually position the fixture and/or mirror so the light shines on a flat
surface and focus the beam.
6. If there is an off-center “hot spot,” the lamp is not centered in the reflec-
tor. “Pull” the hot spot into the center of the field with small adjustments
of one or more of the screws.
7. If the light is significantly brighter in the center of the field than it is at the
edge, the lamp is too far forward in the reflector. Pull the lamp in by turn-
ing all three screws clockwise 1/4-turn at a time until the light is evenly
distributed.
