Installation and maintenance
Mounting the bracket
A pre-mounted hanging bracket is provided, with screwknobs at both sides of the scanner. This
bracket can be used to install the unit to a fixed structure, such as a T-bar or truss.
Installing the scanner in a hanging position
When you wish to hang the scanner against a wall, ceiling or beam, make sure to use proper
installation tools and let a skilled technician install the scanner for you.
When you wish to install the scanner to a lighting stand or truss system, use a G-clamp or halfcoupler
for optimal, safe and stable fixation. Check the technical specifications of your light stand or truss
system to gather more information on maximal loads and other safety precautions.
Safety eye:
When installing this fixture in a hanging position, the unit must be secured using a safety cable. The
safety eye on the bottom on the scanner is intended for this and is capable of carrying the weight of
the scanner. The safety cable holds the scanner if the original mounting hardware breaks, preventing
injury and damage. Every lighting fixture that is used hanging should be provided with a safety cable.
Transport
When using this fixture in mobile setups, provide sufficient protection during transport. Use the original
packaging of this unit, or use a professional flightcase with proper foam inlay. This way the electronics,
optics and housing are protected against severe shocks, exterior damage and failing electronics.
Make sure the moving parts of the scanner (pan and tilt motors) are secured during transport. Shocks
and fierce movement of mirror and stepping motors may cause permanent damage.
After use, let the unit cool down for at least 10 minutes. When using DMX, use the 'black out' option on
your DMX controller. This way the unit is positioned in a static stand-by mode and the internal fan is
able to cool down the internal electronics, which decreases the chance of damage during transport.
Replacing the internal fuse
First check whether a failing power supply may be the cause of malfunction. When you suspect that
the internal fuse is broken, the fuse can be replaced by removing the fuse cover, located directly below
the power inlet.
WARNING: Before changing the fuse, always disconnect the fixture from your wall outlet or any other
power supply to prevent electric shocks.
Always replace a broken fuse with a fuse that has the same type and rating. After the fuse has been
replaced, always close the fuse-cover. Reconnect the fixture to your power supply and check whether
the problem is solved. When this does not solve your problem, contact your local dealer for help.
Spare parts
This unit has no user serviceable parts inside. When any damage to internal components occur,
contact your local dealer or a specialized technician in order to repair the fixture.
Cleaning:
Clean the housing of the fixture frequently with a damp cloth, to remove dust and/or dirt. WARNING:
Always disconnect the fixture from your wall outlet or other power supply and let the fixture dry before
reconnecting it. This prevents possible electrical shocks.
