Varyscan
You should clean the optical parts of your Varyscan
scan. After having opened the casing as explained above, take out the effect wheel slide-in (see
sketch page 4) and put it on an underlay in front of you. Take a fuzz-free rag and a detergent for
windows and clean the effect filters on the effect wheel.
Subsequently clean both lenses (sketch page 4). In order to clean the lens easily, loosen the screw
which fixes the lens and remove the lens. Now it is easy to clean from the outside and the inside. Take
out the colour wheel slide-in in order to clean the dichroitic filters. Put in the lens, the effect wheel slide-
in and the colour wheel slide-in. Do not forget to tighten the screw which fixes the lens.
2. Cleaning of ventilation
You should check regularly the function of the ventilators. Above all take care that ventilation inlets and
the interior of the Varyscan* are free from fuzzes and other dust. Open both lids of your Varyscan
screwing off the screws from the lids. Now clean your Varyscan* carefully with a vacuum cleaner. Now
screw down the lid. Take care that you use the sheet metal screws for closing the smaller lid.
Attention:
Take care that you do not twist or damage any parts while cleaning
your scan!
3. Oiling of rotating gobos
Procure a syringe with a thin needle, customary in trade (grind off the tip, so it will be blunt - no risk of
injury!!), and fill it with our special oil. On no account use another kind of oil, because our oil is a
special mixture. Now syringe the oil between the brass gear wheels and the brass plate and turn the
rotating gobos by hand.
Attention: Do not use too much oil!
General Information about DMX512 record
The DMX512 record is devided in 512 addresses. You have 512 addresses for your disposal. To be
able to connect different appliances with a DMX-controller, it is necessary to determine the number of
DMX-channels for every appliance. The occupation of channels of a scan could be like that for
example:
channel 1
x-movement
channel 2
y-movement
channel 3
gobo/effect wheel
channel 4
colour
channel 5
shutter/dimmer
channel 6
iris/gobo positioning/gobo rotation
In order that not every connected DMX-appliance performs same functions, the appliances are
addressed in series; i.e. for the first appliance the first 6 addresses are used (be right for an
appliance with six channels), for the second one (appliance with six channels) the next 6 addresses of
all the DMX-addresses are used (see for example Varyscan
