OPERATIONAL FEATURES

Description

Power-on re-leveling (PORL)

If a car stops at a door zone due to the failure of normal power, the car will re-level to secure the floor level with the doors open after normal power has recovered. 

Safe landing (SFL)

If there is a malfunction and the elevator stops between floors, the controller performs a diagnostic check before moving the elevator to the nearest floor.

Next landing (NXL)

If the elevator doors cannot open fully at the destination floor for any reason, the doors will close and the elevator proceed to the next floor.

Continuity of service (COS)*

A car experiencing trouble is automatically withdrawn from group operation to protect overall group performance.

Automatic bypass (ABP)

An overloaded car will bypass hall calls in order to maintain maximum operating efficiency.

Overload holding stop (OLH)

The elevator buzzer rings to indicate the car is overloaded.

Automatic hall call registration (FSAT)

If one car cannot carry all waiting passengers, another car is automatically dispatched for the remainder.

Car call canceling (CCC)

When a car responds to the final car call in either direction, the system automatically checks and clears the remaining calls from memory.

False call canceling - Automatic (FCC-A)

If the number of car calls registered does not correspond to the number of passengers, all calls are canceled to avoid unnecessary stops.

Car light/fan shut off - Automatic (CLO-A/CFO-A)

If there is no call within a preset time period, the car light/fan is automatically shut off to conserve energy.

Backup operation for group control microprocessor  (GCBK)*

The backup function installed in the system prevents the loss of group control due to failure of a microprocessor or transmission line.

FEATURE

DESCRIPTION

Car call erase (FCC-P)

If the wrong floor button is pressed, it can be canceled by pressing the same button again.

Hall call erase (FHC-P)

If the call button is pressed accidentally, it can be canceled by pressing the button again.

Remote-control car stop (RCS)

With a key switch, a car can be called to a specified floor (on completion of service) and automatically withdrawn from service.

Secret call service (SCS-B)

Car buttons can be locked and accessed only by entering a secret code in the car-operating panel.

Non-service to specific floor - Car button type  (NS-CB)

Service to specific floors can be suspended by locking floor buttons on the car-operating panel.

A given number of cars can be taken out of service for maintenance or energy saving via a key switch installed at a specified floor.

Return operation (RET)

A car can be called to a specified floor for independent use using a key switch installed on the supervisory panel (option).

Attendant service (AS)

Operation mode is switch able between fully automatic and attendant service using an override switch in the car operating panel.

Independent service (IND)

A car can be isolated from group service and used without interruption using the override switch in the car-operating panel.

FEATURE

DESCRIPTION

Expert system and fuzzy logic*

The system performs group control using expert knowledge, which is programmed applying the expert system and fuzzy logic, to maximize the effectiveness of each elevator operation.

Psychological waiting time evaluation*

This system predicts the psychological waiting time of passengers for each hall call, and allocates cars to minimize them. Moreover, psychological waiting time evaluation rules are changed automatically according  to actual service conditions

Strategic overall assignment*

The system predicts near-future car positions and hall calls. Car assignment is performed considering not only current but also these predicted data.

Car travel time evaluation

To reduce car travel time, each car is allocated to hall calls with consideration to the number of car calls.

Distinction of traffic flow with neural networks (NN)

The system uses neural networks to recognize the distinctive patterns of traffic flows in real time with high precision. This results in optimizing the selection and cancellation of operation

Car allocation tuning (CAT)

The system controls the number of cars allocated or parked to the crowded floors according to traffic conditions on each floor and car status.

Dynamic rule-set optimizer (DRO)

Using Neural Network technology, the system predicts traffic flow in the building. The optimal rule-set for group control will be selected through real-time simulations according to the predicted traffic.

Destination oriented prediction system (DOAS-S)

When a passenger presses a destination floor button on the Hall Operating Panel, the service car will be immediately indicated next to the destination floor button. The system dispatches the cars according to destination floors to improve traffic efficiency and minimize congestion. (Cannot be combined with IUP.)

Peak traffic control (PTC)*

To alleviate temporary traffic congestion, cars are automatically assigned (in preferential order) to floors with the heaviest traffic.

Cars, which have finished service, are made to stand by so that near-future stops and predicted calls do not lengthen.

Intense up peak (IUP)*

To improve carrying efficiency, the elevator group is divided into two banks of cars during peak periods to serve upper and lower floors.

Up peak service (UPS)*

Controls the timing and distribution of cars assigned to meet traffic demand during increased upward service.

Down peak service (DPS)*

Controls the timing and distribution of cars assigned to meet traffic demand during increased downward service.

Forced floor stop (FFS)

Each car in the elevator bank will stop at a specified floor on every trip--without being called.

Main floor parking (MFP)

An available car will park at the main floor with its doors open.

Energy-saving operation - Number of cars (ESO-N)

When elevator service is set to a higher level than warranted by the actual traffic conditions, the system reduces the number of cars in service.

Special floor priority service (SFPS)*

Provides preferential car service to a specified floor (e.g., VIP rooms) when a hall call is made at that floor.

Closest-car priority service (CNPS)*

With a bank of elevators, the car in the elevator shaft closest to the call button pressed will respond first.

Light-load priority service (UCPS)*

When traffic is light, empty or light-load cars will be given priority over full cars to minimize users' travel time.

Special car priority service (SCPS)*

Assigns priority to special cars (e.g., observation elevator or elevator with basement service) in the group control system. (Cannot be conbined with hall indicator.)

Congested-floor service (CFS)*

The system monitors the degree of traffic density or flows in the building and automatically assigns cars to the most crowded floors to alleviate traffic congestion quickly.

Bank-separation service (BSO)*

The hall buttons can be divided into groups, for independent group control to serve special needs or different floors.

VIP operation (VIP-S)*

A specified car can be withdrawn from group service for special or VIP service

Lunchtime service (LTS)*

Car assignment can adjusted to favor canteen or restaurant floors to accommodate high demand during lunchtime.

Main floor changeover operation (TFS)

The designated main floor can be changed by manual switch or time clock operation to suit buildings with alternating main floors.
