3. Installation
3.1. Fitting/Exchanging the lamp
DANGER!
Install the lamp with the fixture switched off.
Unplug from power supply before opening unit!
To insert the lamp, open the small cover at the head’s rear panel (see the drawings) by loosening the 2
Phillips screws on the cover.
Gently pull out the lamp assemby.
Remove the old lamp from the socket and
insert the new lamp.
Do not install a lamp with a higher wattage
as it may generate temperatures that the
fixture was not designed for.
Damages caused by non-observance are
not covered by the warranty. Please follow
the lamp manufacturer‘s notes!
Do not touch the glass bulb barehanded
during the installation! Make sure that the
lamp is installed tightly into the lamp
assembly.
Reinsert the lamp assembly and tighten
the 2 screws.
Before striking the lamp, reset the
"LAti"
counter in the main menu of the Control Panel by pressing the
[Up]
and
[Down]
keys in one time and then confirming with the
[Enter]
key.
Do not operate the fixture with the housing open!
Lamp adjustment
The
ARENA COLOUR WASH
lamp holder is aligned at the factory. Due to
differences between lamps, fine adjustment may improve light output.
Strike the lamp and focus the light on a flat surface (wall). Center the hotspot
(the brightest part of the beam) using the 3 adjustment screws
A, B, and C
(see the drawing). Turn one screw at a time to drag the hotspot diagonally
across the projected image. If you cannot detect a hotspot, adjust the lamp
until the light is even.
To reduce a hotspot, “pull“ the lamp in by turning all three screws
A, B, and C
clockwise ¼ turn one 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 the light
output is low, then the lamp is too far back in the reflector. “Push“ the lamp out
by turning the screws
A, B, and C
counterclockwise ¼ turn one at a time until
the light is brighter and evenly distributed.
