Electric Components Overview

The elevator electrical system manages all control, communication, and safety functions. Inside the car, the push button allows passengers to select floors, while the COP LOP HOP (Car Operating Panel, Landing Operating Panel, and Hall Operating Panel) provide centralized control interfaces. The control cabinet accessories include relays, circuit breakers, and power supplies that support the main controller. Depending on building traffic, the serial controlling system connects devices with minimal wiring, the parallel controlling system coordinates two elevators to share calls efficiently, and the homelift controlling system offers simplified logic for residential applications. Various electrical parts such as switches, sensors, and connectors ensure reliable daily operation. The load weighing device measures car occupancy to prevent overload. An access control system restricts floor access using RFID or keypads. An ARD & transformer & EL (Automatic Rescue Device, transformer, and emergency lighting) provide backup power during outages. The inspection box & advertising allow maintenance technicians to run the car at reduced speed while displaying commercial content on integrated screens. Finally, the elevator cable (traveling cable) flexibly connects the car to the fixed building wiring, carrying power and signals for all car-mounted electrical devices.
