Elevator control system circuit diagram

  • Do elevators use PLC?

    The Elevator PLC System is designed for existing Schindler and Westinghouse relay-controlled hydraulic and traction elevators.
    A trained Schindler technician can install the efficient and reliable Elevator PLC upgrade in far less time, and at a fraction of the cost, of a major modernization..

  • How do elevator control systems work?

    The primary function of the elevator controller is essentially to receive and process a variety of signals from several different components of a whole elevator system.
    It is able to send signals in response to the ones it receives in order to operate all of the other components in the system..

  • What is elevator circuit?

    An elevator safety circuit has a series chain of contacts connected between at least one safety relay and an electric power supply and a monitoring device monitoring the voltage and current in the series chain.
    A signal from the safety relay is transmitted to an elevator control..

  • What is inside an elevator control panel?

    Besides floor selection buttons, which are used to decide where the elevator will stop, the car operating panel includes other operation and emergency buttons.
    Those extra buttons include further functions and controls such as door open, door close, emergency stop, emergency alarm, or telephone..

  • Control buttons: Even in smart elevators, there will still be a few essential button functions in the cab.
    Elevator controller buttons include the door open, door close, emergency call, and emergency stop buttons.
  • The elevator system can be divided into machine room part, hoistway part, floor station part and elevator case part.
    The core control system of elevator control system based on PLC is the main phase l of PLC.
    Our signal input is transmitted to the PLC host through the PLC interface.
The ASM chart is a convenient tool that translates the system specifications to an information diagram in which the sequence of operations and the conditions 

How does an elevator control system work?

If the elevator reaches the correct floor, the elevator-control system sends the signals to a motor driver, which stops the motor, and then the pumping of fluid is halted at that position

While lowering, the car stays on exact floor by controlling the signals to the valve mechanism to open or close the valve

What is controller-datapath approach in elevator control circuit?

To my colleagues; for helping me whenever in doubt

In the design procedure of the elevator control circuit, the controller- Datapath approach was used

In this approach, all the functional and memory are concentrated in the Datapath while the control signals are generated by a simpler sequential machine(controller)

What is the elevator main control board interface?

The elevator main control board interfaces to other parts of the elevator system using a wired interface

A CAN or RS-485 transceiver may be used to interface to the elevator system bus

The wired interface may include isolation

An Elevator is a vertical transport system that carries people or goods between the floors of building safely and efficiently. There are d…
