4) Construction
4.1) Mechanical Construction of the Projector
The light sheet metal housing with double wall heat isolation system is mounted in a
stable support yoke (8). Fine adjustment (2) is accomplished by means of adjustable
telescoping rails on either side (7). The image plane with slide carrier can be
r/- 90° by losening the clamping lever (9) on the upper part of the housing.
The 18x 18 cm diapositives individually can be exactly adjusted with the aid of
adjustment screws. The slide carrier is held in exact position by means of a spring
loaded locking pin (11). By lifting the ball knob (11), the slide may be freely moved
into the new position where it locks into position automatically.
4.2) Electrical Assembly of theProjector
The complete electrical section is located in the black finished lower housing area; It
is mounted to the green main housing with 4 screws.
4.3) Slide Carrier and Slide Cooling Fan
The slide cooling fan has two mounting configurations (It is mounted with 2 captured
hex head screws- No. 4 hex wrench included):
The upper position, closest to the slide, provides optimum cooling, the slide carrrier
can however be rotated only +/- 6°.
When choosing the lower position, the slide carrrier can be rotated ± 90°.
ATTENTION:
Slide cooling with the fan in the lower position is less efficient!
4.3.1) Electrical Connection of the Slide Cooling Fan
The electrical connection of the slide cooling fan is accomplished with a 5- pole
connector, so that the fan housing can be removed from the projector both
mechanically and electrically. 2 contacts in this connector are wire in such a way that
when the connector is not plugged in the projector is shut down.
4.3.2) Mode Switch "TURBO - Standard - Low Noise"
A "TURBO - Standard - Low Noise" mode switch is located on the slide cooling fan
housing (12).
ATTENTION:
Use "Low- Noise" Mode only when silent operation is necessary, as
cooling efficiency is reduced. Do not project dark slides or slides with large dark
regions in this case. Use “TURBO” Mode if noise doesn´t matter and dark slides
should be protected for lasting projections.
