ELEVATOR INSTALLATIONS
NexWay

● Control, Door and Operation Systems
Selective collective (2BC)
The system consists of call buttons in the car, and a
riser of up and down destination floor buttons installed
at each elevator hall (single button at terminal floors),
which connect electrically with microprocessors
supervising floor selection and direction of travel. A car
will respond to those car and hall calls that comply with
its direction of service.
When there are no more calls registered for the car’s
direction of travel, the car’s service direction is
reversed.
∑AI-22 & ∑AI-2200C Group Control Systems
The systems, which employ an intelligent expert
system and fuzzy logic, are specially designed for
group control of 3 to 8 elevators (as described above).
Practical information required for group control is
stored in the system's memory as a “Knowledge
Database”. Drawing from this database, various traffic
conditions are monitored and analyzed applying
IF-THEN decision rules to maximize the effectiveness
of each elevator operation.
The systems perform assignments to the most-used
locations, and thereby provide superb efficiency and
service.
In addition to the above, ΣAI-2200C system performs
optimal car allocation using Dynamic Rule-set
Optimizer.

Notes:
*1: Please consult our local agents if the maximum travel exceeds the values specified in the above table.
*2: For the rated capacity 2250kg to 3000kg, please consult our local agents for maximum travel.
*3: For some elevator specifications, the floor height (distance between floors) must be a minimum of 2500mm.
Please consult our local agents if the floor height is less than “Entrance height HH + 700mm”.
Notes:
*1: The symbol shown in the table indicates that a technical inquiry is required.
The symbol ● shown in the table indicates that a technical inquiry is required depending on conditions.
*2: Refer to page 5 to 12 for the hoistway and machine room layout plans for the models with specifications marked in gray ( ).
For the layouts for models with other specifications, please consult our local agents.
BASIC SPECIFICATIONS OF THE NexWay
1 2

● Elevator installations should be properly
planned according to such factors as the
size and nature or kind of the building,
the traffic flow and peak traffic demand
or conditions, the location of public
transportation facilities and stores.
● Dispersing elevators in different areas of
a building adversely affects their
passenger-carrying efficiency. Therefore,
elevators should, as far as possible, be
concentrated in the center of the
building.
● When two groups of elevators face each
other, ample space should be left
between the groups.
● The number of elevators in each group
should be decided on the basis of the
physical arrangement of the elevators
and the floors served.
● As much as possible, all the floors
served by one group of elevators should
be functionally and structurally similar.
Dissimilarity among the floors served will
result in a drop in service level.
● In residential buildings, hotels, and the
like, it is not desirable for the elevator
hall to be located farther than 50 meters
from any apartment or room.
● In steel-reinforced concrete
buildings, design the hoistways so
that concrete walls are at least
120mm thick.
● Hoistways must be no more than
30mm out of plumb.
● No wiring or distribution panels
should be built into or mounted on
hoistway walls.
● It is forbidden under most building
codes to install any conduit work or
piping in hoistways except as
required for the elevator itself.
● Pit-depth and overhead-height
dimensions must always be at least
the minimum shown in the drawings.
● If it proves necessary to make use of
space below the pit, contact our
local subcontractor.
● When the building is to be of steel
construction, our local
subcontractor should be brought
into the discussion at the earliest
possible moment.
● Provide the recommended width
and height to assure that there will
be sufficient room for inspection and
maintenance.
● Since the elevator drive equipment
generates considerable heat,
sufficient ventilation and or air-
conditioning capacity must be
provided to assure that the
machine-room temperature does
not exceed 40°C.
Refer to elevator site requirements
at page 18 for details.
● When occupied areas of the building
are in close proximity to the
machine room, such as in the case
of elevators for the low and middle
floors of a high-rise building, it may
be desirable to provide additional
soundproofing or intervening walls.

Elevator traffic reaches a peak when people employed
in the building arrive for work in the morning, when
they break for lunch at midday, and when they leave
for home in the evening. Obviously, the elevators must
be capable of handling the increased traffic during
these peaks. And during actual business hours, the
elevators must be able to respond promptly to serve
the people who are on the move inside the building as
well as those who arrive at or leave the building. So
that the elevators best suited to the conditions and
environment at hand can be selected, Mitsubishi
Electric applies computer simulation, traffic
computation, and other techniques based on its wealth
of experience in this field to offer a wide range of
elevator consulting services. Given below are reference
data useful for general planning.
Selecting the Elevator Speed
The maximum number of floors served in a building
serves as the criterion for selecting the speed at which
the elevators should travel. To select elevators using
the chart below, if the building has 23 floors, select
elevators with a speed of 3.5m/sec or 4.0m/sec.
Note: The following chart shows the recommended elevator
speed per maximum number of service floors. The best
suited speed varies depending on the following factors:
*Building usage;
*Single-tenant building or multi-tenant building;
*Floor heights;
*Population in the building;
*Number of elevators in the group; or
*Capacity of the elevator.
Please consult our local agents for details.

● Power Feeder Data *1
FLU: current during upward operation with full load at power supply voltage of 400V.
FLAcc: current while accelerating with full load at power supply voltage of 400V.
Notes:
*1: The values in the table above are for the case where power supply voltage is 400V. If the power supply voltage is within the range of
380 to 440V (except for 400V), calculate values by referring to page 16. If the power supply voltage is not within the range of 380 to
440V, please consult our local agents.
*2: If power supply voltage (E) is a value other than 400V, FLU current and FLAcc current are obtained via the following formula.
(FLU/FLAcc current (A) at E (V)) = (Current at 400V) × (400/E (V))

ELECTRICAL INSTALLATION
15 16

Traction-Machinery Power Supply
It is necessary to install power-supply equipment of
sufficient capacity to ensure the elevators accelerating
smoothly and landing accurately.
The power supply should be kept within a voltage-
fluctuation range of +5 ~ -10%, and a voltage-
imbalance factor of 5%.
When selecting protective breakers on the power-
supply side, be guided by voltage ratings of the
no-fuse breakers supplied with the elevators.
Ventilation Equipment
A machine-room ventilation device having a sufficient
capacity to keep the room temperature below 40°C is
required.
A ventilation window should also be installed at the
opposite side of ventilation fan.
Power Supply for Lighting
Lighting for the elevator cars and indicators, where
possible, should be supplied via a separate circuit that
will not be affected by power failures elsewhere.
Intercom (where necessary)
This is essential to establish the communication
between elevator passengers and outside in case of
emergency.
The master station transceiver is usually in a location
readily accessible to the supervisor, in the central
supervisor's room or elevator lobby. The wiring work
between the master station and the elevator machine
room is not included in the elevator contract.
To facilitate piping and wiring, it is desirable to decide
on the position of the master station at the earliest
stage of building design.
Lighting Equipment
The machine room should be fitted with good lighting
for maintenance work. The light switch should be
positioned close to the machine-room entrance.
Inspection Power Outlets
These should be installed in the machine room and pit
for use during inspection and maintenance.
● Electrical Equipment Required for Elevator Operation
Notes:
*1: The minimum size of ground wire is determined according to the ampere rating of the NF
breaker installed at the power source side.
*2: The ampere rating of the power-source NF breaker should be of one step larger than of
the receiving-box NF breaker installed in the elevator machine room.
NF breaker *2
Ground wire *1
The following items are excluded from Mitsubishi Electric’s elevator installation work, and are therefore the
responsibility of the building owner or general contractor:
• Construction of the elevator machine room with proper beams and slabs, equipped with a lock, complete with
illumination, ventilation and waterproofing.
• Access to the elevator machine room sufficient to allow passage of the control panel and traction machine.
• Architectural finishing of the machine room floor, and the walls and floors in the vicinity of the entrance hall after
installation has been completed.
• Construction of an illuminated, ventilated and waterproofed elevator hoistway.

• The laying of conduits and wiring between the elevator pit and the terminating point for the devices installed
outside the hoistway, such as the emergency bell, intercom, monitoring and security devices, etc.
• The power consumed in installation work and test operations.
• All the necessary building materials for grouting in of brackets, bolts, etc.
• The test provision and subsequent alteration as required, and eventual removal of the scaffolding as required by
the elevator contractor, and any other protection of the work as may be required during the process.
• The provision of a suitable, locked space for the storage of elevator equipment and tools during elevator
installation.
• The security system, such as a card reader, connected to Mitsubishi Electric's elevator controller, when supplied
by the building owner or general contractor.
* Work responsibilities in installation and construction shall be determined according to local laws. Please consult our local agents for details.
Work Not Included in Elevator Contract
• The temperature of the machine room and elevator hoistway shall be below 40˚C.
• The following conditions are required for maintaining elevator performance.
a. The relative humidity shall be below 90% on a monthly average and below 95% on a daily average.
b. The machine room and the elevator hoistway shall be finished with mortar or other materials so as to prevent
concrete dust.
c. Prevention shall be provided against icing and condensation occurring due to a rapid drop in the temperature in
the machine room and elevator hoistway.
• Voltage fluctuation shall be within a range of +5% to -10%.
Elevator Site Requirements
Please include the following information when ordering or requesting estimates:
• The desired number of units, speed and loading capacity.
• The number of stops or number of floors to be served.
• The total elevator travel and each floor-to-floor height.
• Operation system.
• Selected design and size of car.
• Entrance design.
• Signal equipment.
• A sketch of the part of the building where the elevators are to be installed.
• The voltage, number of phases, and frequency of the power source for the motor and lighting.
