The FILTER WHEEL movement and position is controlled by a stepper motor driver (U8) located
onboard to the Power board that drives an stepper motor model 23LM-C304-76W ( for mono
cuvette ) or an stepper motor model 103-547-52500 ( for double cuvette ) and an optical sensor
barrel that informs when the arm is at home position.
The movement from the motor to the wheel is transferred ( for the mono cuvette ) by a mechanism
driven from a belt and two pulleys.
The movement from the motor to the wheel is transferred ( for the double cuvette ) directly.
