Regardless of the use or purpose, the NEXIEZ is a best match solution for virtually any elevator installation.

Reusing Energy Max. energy-saving effects: 35% Regenerative Converter (PCNV) (Optional) Elevators usually travel using power from a power supply (powered operation); however, when they travel down with a heavy car load or up with a light car load (regenerative operation), the traction machine functions as a power generator. Although the power generated during traction machine operation is usually dissipated as heat, the regenerative converter transmits the power back to the distribution transformer and feeds it into the electrical network in the building along with electricity from the power...

Efficiency Forecasting a Near-future Hall Call to Reduce Long Waits Group Control Systems: ΣAI-22 and ΣAI-2200C When a building is expected to have heavy traffic, optimum car allocation suited for every condition makes a big difference in preventing congestion at a lobby floor and reducing long waits. Average waiting time Cooperative Optimization Assignment When a hall call is registered, the algorithm assumes a near-future calls that could require long waits. Through evaluation of the registered hall call and the forecasted call, the best car is assigned. All cars work cooperatively for optimum...

Variable Traveling Speed Elevator System (VSE) (Optional) Machine-room-less Elevators With Mitsubishi Electric’s industry-first variable traveling speed elevator system, an elevator can travel faster than its rated speed according to the number of passengers, ultimately reducing waiting and traveling time. As all equipment is installed within the hoistway, there are fewer restrictions on building design except for the actual space required for the hoistway. Architects and interior designers have more design freedom. Waiting Time Reduction Traveling Time Reduction 1.0m/sec Waiting time reduction...

Safety For Safe Boarding Emergency Situations Door Safety Devices Emergency Operation Our reliable safety devices ensure that the doors are clear to open and close. Depending on the type of sensor, the detection area differs. Please refer to page 16 for details. To ensure passenger safety, our elevators are equipped with functions for emergencies like a power failure, fire or earthquake. Power failure Mitsubishi Emergency Landing Device (MELD) (Optional) Upon power failure, a car automatically moves to the nearest floor using a rechargeable battery to facilitate the safe evacuation of passengers....

Standard Design For front return panel ■ EMERGENCY OPERATIONS AND FEATURES Mitsubishi Emergency Landing Upon power failure, a car equipped with this function automatically moves to and stops at the nearest floor using a rechargeable battery, and the doors open to facilitate the safe evacuation Device (MELD) of passengers. (Maximum allowable floor-to-floor distance is 10 meters.) Operation by Emergency Power Upon power failure, predetermined car(s) use the building’s emergency power supply to move to a specified floor, where the doors then open to facilitate the safe evacuation of passengers....

Down Peak Service (DPS) If a car has stopped between floors due to some equipment malfunction, the controller checks the cause, and if it is considered safe to move the car, the car will move to the nearest floor at a low speed and the doors will open. Controls the number of cars to be allocated and the timing of car allocation in order to meet increased demand for downward travel during office leaving time, hotel check-out times etc., to minimize passenger waiting time. Forced Floor Stop (FFS) If the elevator doors do not open fully at a destination floor, the doors close, and the car automatically...
