4. Installation
a) Fitting the lamp
To insert the MSD250/2 lamp open the top cover of the projector-head by unscrewing the 3 screws on the cover.
Then open the small lamp cover by unscrewing the 2 fastening screws. If changing the lamp remove the old lamp
from the socket. Insert the lamp in the socket. Do not install a lamp with a higher wattage! A lamp like this generates
temperatures the device is not designed for. Do not touch the glass bulb with bare hands during the installation.
Make sure that the lamp is installed tightly into the socket. Adjust the optimal distance 1-1.5mm from the lens by
turning screw A (see fig. 1 “Lamp Adjustment” below) on the rear panel of the head. Then close the small lamp cover
by screwing the 2 fastening screws tight. Close the top cover of the head and tighten the 3 screws.
b) Lamp adjustment
The lamp holder is aligned at the factory. Due to difference between lamps, fine adjustment may improve light
performance. Strike the lamp, open the shutter and the iris, set the dimmer to 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 screw “A”), it is necessary to adjust only the second position by turning screw “B”, in order to centre the
hot-spot (the brightest part of the beam). If the light on the edge seems to be too bright, you can lower intensity by
moving the lamp closer to the reflector. Do so by turning screw “A” until the light is evenly distributed. If the Light on
the edge seems to be brighter as in the centre, 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.
c) Inserting / Exchanging gobos
Turn off the lamp and allow it cool for at least 10 minutes. Disconnect the fixture from power. To insert the gobos
open the top covers of the head by unscrewing the 3 screws on the top cover and follow the instructions below:
Rotating gobo-wheel
