System introduction
Gel rolls
The gel roll construction of the units consists of two spools, one with a gold knob and the
other with a black knob. The spool with a gold knob has a build-in spring which takes care
of tensioning the gels. You can easily prepare, mount and install gel rolls following the
instructions in this manual. Changing gel rolls in a unit is done without need of any tools in
amatter of minutes.
The units are factory trimmed foe a working range of 11 colours, or a total filter lenght of
3080 mm plus a leader and a tail of 320 mm each. The standard number of colours is
eleven because it gives one colour for each 10% control signal input to a unit. You are free
to change the lenght of each colour within the total lenght of the colour string without
need for readjusting the unit. If however you wish to change the total lenght of the colour
string, you will have to re-trim the unit with the trim pot in the back of the unit. This
described later in this manual. A unit can be trimmed for 2-16 colours.
If the colour string is shorter than the range it will be ripped of the spool and if it´s too
long you won´t be able to reach the end colours.
Cooling
To lenghten the life span of the gels we have fitted each unit with an internal fan. The fan
can run at two speeds, high or low. This is set with the fan switch on each scroller. Running
on low speed will shorten the life span of the gel string and should be used only when
extremely quiet operation is needed.
Rigging a Rainbow scroller system
The units are mounted on the lighting instruments of your choice. You can mount the
splitterbox and the power unit (1 per 24 units) in the truss with G-clamps. The power is fed
into the splitterbox and distributed from there to each unit. The distribution and the
splitterbox depend on if your system is controlled digitally (DMX512) or Analog (0-10V).
The cables used for distribution to the units are of the same sort in both systems.
Standeard four pin XLR connectors are used. (seepage17 on Power/control cables).
On the base of each unit there are three LED indicators. The red LED indicates, trat power
is on. The yellow LED shows the input signal to the unit. The green LED indicates, trat the
incoming DMX data is correct. If the red LED is flashing, it indicates ”auto motor shut off” is
activated – the scroller for some reason cannot reach it´s position.
