Repair Scanner Filter Wheel LH_MO01 The filter wheel stepper motor is connected to the filter wheel by a toothed belt. The filter wheel can hold eight filters (in cw order): 1. free 2. RED-Negative 3. RED-Slide 4. GREEN-Negative 5. GREEN-Slide 6. BLUE-Negative 7. BLUE-Slide 8. Light dimmer The zero position is reached with light sensor LH_LS01. The motor is energised by different currents via LH_MO01_I0 and LH_MO01_I1: A B Arrow dlabr153 Zero position (position for the 1 st exposure) Initialisation position (Position LH_LS01) Direction of rotation I0 0 1 0 1 I1 0 0 1 1 Current 100% 72% 38% 0% The motor runs in half step mode: − Step angle 1,8° − Transmission of 3:1. The filter wheel is turned through 0.3° per step. 150 steps must be performed between the filters. − Direction of rotation of the filter with a cw turning motor: RED-Negative, RED-Slide, GREEN- Negative, etc. − Zero position of the light sensor with a cw turning motor: 6° before the RED-Negative filter − Clock: Indicated by LH_MO01_CLK − Direction: Can be selected by LH_MO01_DIR − When the lamphouse opens, the stepper motor is switched off.

Functions and Properties of the Components in the Exposure Path<br />
Lamphouse<br />
− KG5+IR-UV: Cold glass and IR absorption for<br />
heat filtering<br />
− RG850 for Infrared Scan<br />
− Light dimmer (Mask filter)<br />
− Light shutter<br />
− Exposure filter wheel with 8 positions:<br />
red, green, blue always for frame and slide, light<br />
dimmer, free<br />
Halogen Lamp<br />
The lamp is subject to warming up and ageing<br />
effects. The Prescanner is used instead of a<br />
sensor to measure the lamp brightness<br />
(calibration measurement of each film).<br />
Filters<br />
The lamp drift is compensated by the white<br />
balance in comparison with the RGB colour filters<br />
and the calibration of the Prescanner (only<br />
negative, no slide).<br />
The RG850 filter for the IR-Scan has also to be<br />
calibrated. As the KG5 filter is always in the light<br />
path upon the RGB Scan, it is always calibrated<br />
automatically as well.<br />
Colour Filter Wheel: 50% Filter<br />
For the fast mirror box 135, the 50% filter in the<br />
colour filter wheel has to be moved in for the<br />
Prescan; also for the calibration of the Prescanner<br />
in order to prevent thermal overload of the film<br />
(Fading).<br />
The 50% filter itself need not be calibrated.<br />
