Figure 4 displays the Star governor's Beta parking system. It is mainly made up of a coil, which operates the
governor's interlocking system in case of UCM, and an inductive sensor, which indicates the interlocking system's
positioning to the D-Box.
The protection of this system against UCM is as follows: The D-Box electronic system compares, at all times, the
status of the car doors and the floor level via input signals from the installation. These signals are:
•
Doors closed.
•
Floor level,
•
