When an electronic selector is used a _______ representing the exact location of the floor is stored in memory.

• A. floor location data
• B. pulse count
• C. memory index
• D. step count

Answer: (B)

The exact vertical position is stored as a pulse count. A stable reference point is established (home), and a pulse generator counts how many pulses occur as the car moves. That count translates directly into a precise floor location, so the memory holds the number of pulses corresponding to that floor. This lets the controller know exactly where the car is and stop at the correct floor, regardless of speed changes or brief delays. Other terms like floor location data or memory index don’t convey a precise, repeatable measure of position, and a step count isn’t the standard way elevators encode position in most electronic selectors.
