    ORCA

    The installation friendly elevator control system

    We started the development of the elevator control unit in May 2008 to create a product with modern technology that matches today’s standards. Our product is suitable for controlling geared traction (single-speed or two-speed), regulated traction or hydraulic elevators.

    This elevator controller is a distributed intelligence system which is made up of the following units: central electronics, car inspection station, faceplates and hall stations. The components are communicating via the ORCA bus which is a 4-core cable. Only one 24-core travelling cable is needed between the controller cabinet and the elevator car.

    Upon request the shaft cables, the travelling cable, the faceplates, the door drive cables and the car inspection station may be pre-assembled so the control system can be assembled quickly by connecting them to the appropriate sockets.

    The failure of the individual components does not cause the total shutdown of the control system, only the affected area will be out of service. Of course there are requisite components like the position sensors, the safety controller and monitoring system. Without the units mentioned above the elevator control system cannot operate, resulting in immediate shutdown.

    The main idea of this project came from Dr. László Zákány who unfortunately passed away before the development finished. May he rest in peace.
  2. Main features of ORCA elevator control system:

    The system meets the following standards:
    1. MSZ EN 81-1/2
    2. MSZ EN 12015
    3. MSZ EN 12016
    4. MSZ EN 50178
    5. EC 95/16

    The control panel includes safety circuits for open-door levelling and correction runs.

    Suitable for the following drives:
    1. Rope-traction drives (single-speed and two-speed)
    2. Hydraulic drives:
      1. Direct start
      2. Star-Delta start
      3. With soft starter
    3. Regulated drives
      1. Asynchronous and synchronous engines
      2. Frequency regulated drives
      3. Voltage regulated drives
      4. Open-loop and closed-loop applications

  3. Other features of ORCA elevator control system:

    1. Group control system up to 4 elevators
    2. Service up to 31 stops in lunch time (two-way) mode by default
    3. Short-levels
    4. Extensive parameterization
    5. Macro functions: the basic parameters of the controller are set automatically according to the drive system, only minor fine-tuning is required
    6. Advanced information display on the controller card displaying the following information:
      1. System status
      2. Position of car
      3. Direction of travel
      4. Stored calls
      5. Status of door-drive (open, closed)
      6. Status of door-drive interlocks
      7. Status of safety circuits
      8. Status of position sensors
      9. Occurring error messages
    7. The last 32 errors (with timestamp) caused the elevator to stop or prevented it from start
    8. The last 32 errors (with timestamp) not caused the elevator to stop nor prevented it from start
    9. Only one 24-core travelling cable is need
    10. Only one 4-core cable is needed for the faceplates (upon request prefabricated cabling available)
    11. Pre-assembled interlocks, faceplates and maintenance controllers which are easily connected to the appropriate socket of the car inspection station
    12. Monitoring the temperature of the engine
