Projector Status: Mechanic position is not known

Projector is energized

The MICROCONTROLLER starts the initialization routine:

-load the look-up tables

-look at the accessory slot and projector address

-sets the ECONOMY LAMP RELAY to 82V

-completes a Hardware reset

SLIDE LIFT MOTOR rotates clockwise (max. of 805 steps = one SLIDE LIFTER cycle).

If SENSOR SIGNAL changes from not actuated to actuated, the SLIDE LIFTER is in up position.

Yes = Start tray MOTION.

No = Begin a failure routine, after it has advanced 805 steps without sensor signal change.

slide tray moves forward about 3,5 slides (with software version above 4.2).

Details about tray motion can be obtain from page 3-9.

If the ZERO SENSOR is not actuated, the tray reverses

If the ZERO SENSOR is not actuated, the slide tray continues to advance.

The SLIDE LIFT MOTOR moves clockwise.

When the CAM SENSOR changes from actuated to not actuated, the LIFTER is in the down position.

If the SLIDE IN GATE SENSOR is actuated, the SHUTTER opens.
