6 .4 .4 Adjusting the IR Reflex Film Break Sensor
Position the sensor (arrow) in a way that it “looks” vertically towards the film surface.
The sensor’s view must be perpendicular to the film.
• To adjust the sensitivity of the sensor
thread a film and turn the plastic screw
(arrow) with a screw driver until the red
LED (adjusting aid) blinks.
• Then turn the screw until the LED surely
lights steadily.

The skate lifting device essentially consists of a rotation shaft
with a flat side which
is driven by a solenoid.
$
When active the round side of the shaft presses against a metal plate
Á
and releases
the pressure from the film (the skate is lifted).
$
When not active the flat side of the shaft points towards the metal plate, but does not
touch it - pressure is exerted on film.
$
When the skate is lifted (reverse running or pausing) the gap between the skate and
the runners should range between 0.5 and 1 mm in the area of the upper ceramics
roller.
• The skate lifting can be adjusted by turning the grub screw
Â
(Allen key 2).
The contact areas of the shaft and the plate should be slightly greased.
