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].

Overview

Elenessa is a standard machine room less elevator model sold for overseas market with 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 unique stator-core structure and built-in double brakes.

The slim control board 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 positioned in a box in the wall behind the hall station on the top floor[2], so as not to compromises the aesthetic of the hall[3]. The top floor hall station has a silver keyhole which is used to unlock the control board[4].

On Elenessa elevators, the control board is hidden behind the top floor hall station, and there is a silver keyswitch below the call button to unlock the control board.

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 "Universal Design" and it is also used in NexWay series. This design is also used on Elenessa elevators manufactured by Shanghai Mitsubishi.

Sometime in the early 2010s, the fixtures design was changed again, this time to match with 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[5].
