Replacing a gelstring
At some point you may find that you need to replace the gelstring
in your Color Changer, either because the old one wears out, or
because you want a different selection of colors. ColorSource’s
Autoload procedure makes this easy by walking you through the
procedure, step by step.
Note: The gelstring must be ten frames long for proper operation.
If a frame is damaged, do not remove a frame and splice the
gelstring. Replace the gelstring.
Note: You may install a gelstring with or without a DMX512
source connected to the Power Supply.
Warning: Do not force the rollers to turn when turning them by
hand. If they do not turn easily, you have not disconnected the
DMX512 cable, and should do so immediately.
To replace a gelstring, follow these steps. Press [Menu/No] at any
point in the process to cancel loading.
Remove old gelstring
1. Place the Color Changer on a flat surface with the ColorSource
logo facing up. The power/signal cable connector should be
facing you, with the cable connecting it to output 12 on the
Power Supply (labeled AUTOLOAD).
2. Unscrew the two thumbscrews at the top right and left
corners of the front panel as shown in first picture at left. Lift
the panel by the screws and remove it from the Color Changer.
3. If you are connected to a DMX512 source, set the gelstring to
the DMX512 = 100 position.
4. Disconnect power cable from Color Changer.
5. Gently roll the gelstring all the way onto the right roller, expos-
ing the clear trailer taped on the left roller.
6. Untape trailer from left roller. Remove tape from trailer and
save it.
7. Roll gelstring into a tube, slowly rolling it off the right roller.
8. When you reach the clear leader, untape it from the roller.
Remove the gaffer’s tape from leader and save it. If you expect
to reuse the old gelstring, reroll it in the opposite direction, so
the trailer is on the outside.
