Adjusting the Film height of the cassette
The height of the films in the cassette is adapted by changing the position of
the horizontal film bar holder. For filmsizes: 24-25-26-27-28 inch around the
drum.
Adjust the Film position in left/right
First adapt the cassette to the correct filmwidth by changing the position of the
filmfeeder guiding bars. Check if the film is perfectly in the middle of the
drum.
You can adapt this by moving the complete feeder left or right. For this loosen
the eight screws of the two filmfeeder feet and position the complete feeder so
that the film is perfectly in the middle of the drum.
Take over cylinder
1. Check if the take-over cylinder hits the take-over bar.
2. This is very important because the film should remain upright during the load
process.
3. Ensure that the film feed bridge is down.
4. Proceed as follows:
LTL> 8 RFDREL (reset the solid state for film feed bridge up)
LTL> 1 RFDREL (reset the solid state for the take-over cylinder)
LTL> 8 SFDREL
Put a film in the cassette.
LTL> 8 RFDREL (wait until film bridge is completely down)
(move filmplate to suctioncaps)
LTL> 128 SFDREL
LTL> 8 SFDREL (wait until film bridge is completely up)
LTL> 1 SFDREL
LTL> 128 RFDREL
5. Now the film should hang by it self, without vacuum in the suction caps. If this is
not the case than you should decrease the distance of the bridge up position
towards the take-over plate. Decrease the distance in small steps and ensure that
the distance is equal on both sides.
6. Adapt the speed of the take over cylinder going forward if necessary by turning
the third speed controller.
Film bridge down adjustment
1. Bring the filmbridge in his down position.
2. Move the feederplate as far as possible to the front.(just before mechanical stops
which are installed in left and right top corner of cassette)
3. Adjust the position of the filmbridge so that the suctioncaps are halfway pushed
in.
4. Adjust the hydraulic shock absorber. See below.
5. Do not forget to fix all screws.
