● 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.

Notes: * 1. When the capacity and speed exceed the range shown in the left page, the operation system 2C-2BC should be 2C-ΣAI-22.* 2. Please consult our local subcontractor, when 2C-ΣAI-22 system is required instead of 2C-2BC system.

ΣAI-22＆ΣAI-2200C Group Control SystemsThe 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.

STANDARD INSTALLATION

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℃.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.

ELECTRICAL INSTALLATION

Traction-Machinery Power SupplyIt 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 EquipmentA 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 LightingLighting 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 EquipmentThe 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 OutletsThese 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

● Power Feeder Data

Notes: * 1. If the power supply voltage is other than 400V, the FLU and FLAcc current vary inversely with power supply voltage as follows. (Current at E volts) = (Current at 400 volts) x (400 / E) where, E: power supply voltage

REFERENCE DATA FOR ELEVATOR PLANNING

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 SpeedThe 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.
