The MICROCONTROLLER energizes the TRAY MOTOR for 47 steps (80 tray) or 27 (140 tray) for each slide.
The MICROCONTROLLER checks feedback from tray MOTION CONTROL CIRCUIT.
If more than 4 feedback pulses are missed, exit to the failure routine.
For RANDOM ACCESS: The TRAY MOTOR ON until the position is reached.
For FORWARD/REVERSE BUTTONS:
-tray moves only for one slide
-slide is projected
-if transport button is still pressed,
a slide is lifted up and the tray moves until button is released but stops at the ZERO POSITION.
The MICROCONTROLLER sets the next position into memory.
The SLIDE LIFTER Down procedure starts.
