Lamp adjustment
The lampholder is aligned at the factory. Due to differences between lamps, fine adjustment may improve
light performance.
Strike the lamp, open the shutter and the iris, set the dimmer
intensity onto 100 % and focus the light on a flat surface (wall).
Center the hot-spot (the brightest part of the beam) using the 3
adjustment screws
"A, B, C”
. Turn one screw at a time to drag
the hot-spot diagonally across the projected image. If you cannot
detect a hot-spot, adjust the lamp until the light is even.
To reduce a hot-spot, pull the lamp in by turning all three screws
"A, B, C”
clockwise ¼-turn at a time 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, the lamp is too far back in the reflector. "Push”
the lamp out by turning the screws
"A, B, C”
counterclockwise
¼-turn at a time the light is bright and evenly distributed.
Inserting/Exchanging gobos
DANGER!
Install the gobos with the device switched off only.
Unplug from mains before!
If gobos are to be exchanged, please follow the instructions below:
CAUTION!
Never unscrew the screws of the rotating gobo
as the ball bearing will otherwise be opened!
Remove the fixation-ring with an appropriate tool. Remove the gobo and insert the new gobo. Press the
fixation-ring together and insert it in front of the gobo.
Rigging
The installation of the projector has to be built and constructed in a way that it can hold 10 times the weight
for 1 hour without any harming deformation.
The installation must always be secured with a secondary safety attachment, e.g. an appropriate catch net.
This secondary safety attachment must be constructed in a way that no part of the installation can fall down
if the main attachment fails.
When rigging, derigging or servicing the fixture staying in the area below the installation place, on bridges,
under high working places and other endangered areas is forbidden.
The operator has to make sure that safety-relating and machine-technical installations are approved by an
expert before taking into operation for the first time and after changes before taking into operation another
time.
