Lamp Adjustment - GLP YPOC PRO 250 Instruction Manual

5.3 Lamp adjustment

The optimum distance between the lamp and the lens must be controlled after
every lamp change. The lower deviation amount is min. 1.0mm. Running the
fixture within a lower deviation can cause damages of lamp and/or lens.

between lamps, fine adjustments may improve light performance.
Pease follow this procedure:
1. Strike the lamp (for example in the
intensity of the lamp.
2. Direct the beam straight on a flat and bright surface/wall (beam open, white, no
gobo, no effects).
Remark: As the optimum distance of the lamp from lens was adjusted during
the installation or changing the lamp (by turning the screw A), it is necessary to
adjust only the second position by turning the screw B, in order to center the
so-called 'Hot-Spot' (the brightest part of the beam).
3. If the Hot-Spot is not in the middle, you can adjust this by turning the screw B.
4. If the Hot-Spot is too bright and the beam not even, you can adjust this again
by turning the screw A. clockwise (get nearer towards the reflector). Remark:
A complete even beam can't be reached because of the design of the lamp.
5. Appears the beam more bright at the edge, you can adjust this by turning the
screw A counter-clockwise (get nearer towards the lens).
Attention: Never remain the minimum distance between lamp and lens
(1.0 mm). Is there any doubt, open the fixture and control the distance!
