Mitsubishi Elenessa is the current machine room less elevator model produced by Mitsubishi Electric and Shanghai Mitsubishi. It was introduced in October 2001[1] as a successor of Mitsubishi GPQ and was later succeeded by NEXIEZ-MRL in 2011[1].

Description

Elenessa is a standard machine room less elevator model sold for overseas market. It is mainly used for low to mid rise commercial and residential buildings, as well as transportation facilities such as train stations and airports. It is equipped with a thin permanent magnet (PM), synchronous cylindrical machine installed on the top of the hoistway. This machine has a joint-lapped core technology which produces high-density magnetic fields and able to lower the energy use as well as reducing CO2 emissions. Other features of the machine are the unique stator-core structure and built-in double brakes.

Elenessa complies with EN81-20:2014, EN81-50:2014 and other codes such as GB standards in China[2] and Hong Kong's Code of Practice[3] (which is stricter than those standard) except North America where it doesn't comply with ASME A17.1[4].

Slim control board

The model features a slim control board, which features a VVVF inverter, high-accumulation LSI, and low-noise PWM inverter. It is installed inside the hoistway near the PM machine. There is also an Integrated Power Unit (IPU) which acts as a high-efficient power supply circuit for the machine drive. Unlike any other machine room less models, the control board is installed in a box on the wall behind the landing hall station on the top floor. The top floor hall station has a lock which is used to unlock the control board[5]. This unique configuration was meant to save space and not compromising the building's interior aesthetic[6]. With this configuration, a separate cabinet to house the control board is no longer needed.

In Hong Kong, China, the Elenessa still requires a separate control cabinet. This is because the model conforms with Hong Kong's "Code of Practice", which requires the main power supply switch and security camera monitor to be implemented with the original compact control board console.

Universal Design

Elenessa was one of Mitsubishi's two elevator models (the other one being NexWay-S Series AW) to adopt the company's "Universal Design" principle, a new elevator interior design to provide a safer and more comfortable ride for all passengers. This new design includes a number of new features, such as newly redesigned buttons with tactile legend and enlarged door open button, enlarged interior floor indicator, and thicker handrails.

Elenessa Series-IP/AP Version 2

The Elenessa Series-IP/AP was upgraded in 2009 into Version 2. This version received several new features, such as regenerative converter (optional), energy saving features (examples; reduced numbers of cars, allocation control, car light/fan shut off, etc.), variable traveling speed elevator system (VSE, optional), and DOAS destination dispatch as an option. It is also equipped with AI (Artificial Intelligence) Neural Network technology, divided into two basic group control systems; (Sigma)AI-22 System (for 2-4 cars in each group, for small to medium-size buildings) and (Sigma)AI-2200C (for 3-8 cars in each group, for large buildings). For Series-IP, it received an extended rated capacity from 1600 kilograms to 2500 kilograms.

Signal fixtures

The design of the fixtures for early Elenessa (and also ELEPAQ-i in Japan) elevators installed from 2001 to early 2010s have been changed drastically. The font of the number on the button has been changed from Helvetica to Gill Sans Medim. The buttons are now barrel shaped, colored black and has orange illuminating tactile legend to make it easier to operate by the visually-impaired people. The door open button has been enlarged 1.6 times to prevent confusion with the door close button. In addition, although the LED dot matrix display (which has been used since the GRANDEE model was launched in 1990) is continuously used for the floor indicators, the size of the letters has been enlarged 1.6 times except for those found on the car station for the wheelchair, making it easier to see. For elevators with the car station installed on the side wall, the alarm button is positioned in one row with the door control buttons below the floor buttons. The button for main/exit floor is green and raised about 5 mm than the rest of the buttons. Mitsubishi introduced this design as part of their "Universal Design" principle to provide a safer and more comfortable ride for all passengers. It is also used in NexWay series.

In 2013, Elenessa received a new design of fixtures which is also currently used on the NEXIEZ series. The buttons are now round stainless steel with tactile and yellow orange illumination. In addition of yellow orange, a blue and white illuminations have also been added for the buttons. Indicators now uses LED segmented display as standard, although the LED dot matrix and LCD ones are also used as an option. For car station installed on the side wall, it follows the same configuration found in Elenessa and NexWay models; the alarm button is positioned in one row with the door control buttons below the floor buttons. There is no green button for the main/exit floor, except in European countries where it is mandatory[8].
