The list of optional features provided here are not meant to be exhaustive and the customer is encouraged to approach the sales personnel on additional features that are not described here.
Group Control System
The group control system for three or more elevators employs artificial intelligence and fuzzy logic. The highest refined knowledge and experience harnessed in the field of group control have been incorporated into the microprocessors, allowing car assignments to the most used location and thereby providing superb elevator efficiency and optimum service. The following main features are included in the group control system.
Up Peak Service in Group Control
The option only available with the in group control by time relay setting or by manual switch. When more than three up going call are registered on the main landing, the up peak service traffic mode will be actuated, whereby all the elevators will immediately return to the main landing with door open as soon as they accomplished the up peak service mission. This up peak service will regain to normal service when the up peak service time is over which is determined either by time relay setting or by manual switch.
Down Peak Service in Group Control
The option only available with the in group control by time relay setting or by manual switch. When the situation in which elevators descend to the main landing fully loaded appears, the down peak service travel mode will be actuated, whereby all the elevators will immediately return to the top landing with door open as soon as they accomplished the up peak service mission. This down peak service will regain to normal service when the up peak service time is over which is determined either by time relay setting or by manual switch.
Zoned Waiting Service
This option only available with the in group control. When every elevator stayed waiting more than 60 seconds, the group control activated the zoned waiting service for example, a) if no elevator is located on the main landing and the landing below it, the system will assign an elevator with easier access to the main landing, waiting there with door closed. b) if two of the elevators are in the normal service while no elevator is located on any of the upper floors above the intermediate one, the system will assign an elevator with easier access to the predetermined upper landing, waiting there with door closed.
Operating By Emergency Power (Source- Automatic)
When the normal power supply fails, this optional feature will direct each elevator automatically to a specified floor, on-by-one, powered by the building's standby generator. When the elevators car arrives at the specified floor, the doors will open to allow passengers to disembark and then the elevator will shut down. If required, one or more designed elevators can respond to car and hall calls under the normal operation mode but powered by the building standby generator.
Voice Synthesizer / Announcer
The synthesized voice announcer makes a voice announcement of the approaching floor during every leveling time, elevator travel direction, door closing, playing pre-recorded music and etc.
Uninterrupted Power Supply (UPS)
During normal power failure, the uninterrupted power supply (UPS) converts stored energy from its bank of rechargeable batteries to drive the elevator car to the nearest floor and opens the elevator doors to let the passengers out. The UPS optimizes the use of the stored battery power by selecting the direction which requires the least effort. (This device is suitable for those buildings without an emergency power source allocated for the elevator.)
With this panel, the building superintendent can monitor elevator operations and control emergency operations from the building's control room or electrical room. Position indicators, direction lights and intervenes can be installed on this panel if requested . Additional features can also be accommodated where possible.
Floor Identification by IC Card in Car
The car reader is integrated in the car operating panel for identification check in to the floors which access is permitted by authorization only. There are two ways IC card control in the car available as follows; 1) The card allows for a specific floor only so that the card bearer can have access to all the free access floors and the one which entry is permitted by his card. 2) A specific card allows for the access to several controlled floors so the card bearer can register his or her destination floor within a predetermined time delay after checked in with his card in the elevator car.
Auxiliary Car Operating Panel
An auxiliary car operating panel can be installed on the unoccupied front return panel in large capacity elevators or elevators in high occupancy buildings to provide easier access to passengers in the car. Special auxiliary car operating panels with features catered to the handicapped are also available upon request.
Non- Service of Specified Floor
A key switch can be installed on the maintenance recess panel, which is located on the lower part of the car operating panel, to suspend elevator service to specified floor(s) when activated. This feature allows the client to selectively suspend elevator service to selected floors for various reasons such as unoccupied floors, after office hour's operation or even for security reasons.
VIP Priority Service
With VIP priority service, a VIP landing is preset, where a VIP switch is integrated in the landing call button panel. A VIP service is activated by resetting the switch once, whereby all the landing and in car registration are cancelled immediately and the elevator travel directly to the VIP landing with door open when arrived. Both the automatic door closing and landing calls are blocked to enable the VIP passenger to select the destination floor and closing the door by pushing the door closing push button constantly until the door fully closed. The elevator will regain normal operation once the VIP passenger left the elevator car.
Earthquake Sensor Device
With the earthquake sensor device, a contact signal generated by the earthquake detector is sent to the controller in the event of earthquake. The control system will in turn order the elevators in service to land to the nearest landing with door open to release the passengers.
Floor Identification by IC Card at Landing
The car reader is integrated in the hall call button panel on every landing for identification check in to the floors which access is permitted by authorization only. There are two ways IC card control on the landing available as follow; 1) The card allows its bearer to register a call for the specific floor only on the landing so that the card bearer can have a access to all the free access floors and the one which entry is permitted by his card. 2) A specific card allows for the access to several controlled floors so the card bearer can register his or her destination floor within a predetermined time delay after checked in with his card in the elevator car.
Community Monitoring System
The elevator community monitoring system is to establish a platform for intelligent elevator monitoring cell. The use of anti-interference ability of the CAN bus real-time transmission of date; obtain elevator's fault and base information so that we can monitor the fault information for processing and analysis . This community monitoring system network are flexible with 4 CAN interface and each interface can connect up to 25 elevators which have ability to monitor a total of 100 elevators. When the elevator broke down and records a timely tip, this powerful database features all the fault information and can be collated for analysis in order to guide the maintenance of elevators.
Energy Re generator Variable Frequency Drive System
In case the motor is in action while releasing the mechanical energy of the system, the regenerative electrical energy can charge the DC capacitor bank via the switch of inverter which will cause DC pump voltage. When the pump voltage reaches the set value, the external regenerative energy inverter can start working and rapidly and effectively convey the DC pump energy consumed in the braking resistor to power grid through active inverting. This system implemented for cost saving and environmental friendly.
Voltage Compensating Alternative Stabilizer
The voltage compensating alternative stabilizer is required if the fluctuation of voltage or load changes frequently occurs which will damaged the elevator electrical parts and cause elevator to breakdown. This device will automatically function to maintain the stability of the output voltage before going to the elevator system.
