4. Installation
4.1Fitting the lamp
To insert the lamp (MSD/HSD 250 or MSD250/2) open the cover by loosening the fastening screws at the sides
of the cover.
Do not install a lamp with a higher wattage! A lamp like this generates temperatures the device is not designed for.
Damages caused by non-observance are not subject to warranty.
Insert the lamp now. Do not touch the glass bulb with bare hands during the installation! Please follow the lamp
manufacturer's notes!
Before you close the cover again, make sure that the lamp is installed tightly into the lampholder system.
Adjust the optimal distance 1-1.5 mm from the lens by turning the screw "A" (see the drawings "Lamp adjustment"
below) on the rear panel of the fixture.
Reclose the housing and tighten the fastening screws.
Before striking the lamp, reset the "LAti" counter in the main menu of the control board, by pressing the "+ " and
"-" buttons at the same time and then confirming with the "Enter"-button.
Do not operate this fixture with opened housing-cover!
Lamp adjustment:
Screw"B"
The lampholder is aligned at the factory. Due to differences between lamps, fine adjustment may improve light
performance.
Strike the lamp, cancel all effects, open the shutter and set the dimmer intensity onto 100 % and focus the light
on a flat surface (wall).As the optimum distance of the lamp from lens was adjusted during the installing 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 hot-spot (the brightest part of the beam).
If the hot spot seems to be too bright, you can lower its intensity by moving the lamp closer to the reflector. Do so
by turning the srew "A" until the light is evenly distributed.
If the light on the edge seems to be brighter as in the center, the lamp is too close at the reflector. In this case, you
need to move the lamp away from the reflector until the light is evenly distributed and the beam appears bright
enough.
Install the lamps with the device switched off only.
