Reverse direction call cancellation:
The system automatically cancels the reverse direction calls once the elevator reaches the top or bottom floor to prevent unnecessary trip.

Button card key exclusion:
If the call button is damaged due to damage to the key or external force, the elevator door will not be closed. After a certain time, the system automatically cuts off the button signal, so that the elevator can close the door to continue serving other floors.

Anti-tampering function:
The system can be equipped with a weighing sensor to automatically determine the number of passengers in the car. If too many floor buttons are registered, the elevator will automatically cancel the call of other floors in the car after running 3 floors to avoid unnecessary operation services.

Overload and full load detection:
When the passenger or the load exceeds the rated load of the elevator, the buzzer in the car emits a warning sound and keeps the elevator door open to avoid the danger of the elevator due to overload operation. The system can be equipped with a weighing sensor to automatically determine the number of passengers in the car. If the load exceeds 80%, the elevator will automatically pass the stop without accepting the call of the ride, to avoid adding invalid operation stops.

Automatic level correction:
Due to the change of the carriage load and the extension of the steel cable, when the deviation from the ground level is greater than 1.5 cm, the system can automatically fine-tune and correct it.

Arrival notice:
When the elevator is about to stop at the station, the floor display will flash and notify passengers with an electronic ringtone.
Customers can also choose "Voice Announcer" to facilitate people with reduced mobility to use the elevator.

PARK shutdown operation:
In commercial buildings at night or holidays, etc., when elevator management needs to be shut down, the key switch (or computer monitoring) is used to control the elevator to return to the main floor, stop running, and automatically turn off the lighting and fans.

Lamp fan automatically turns off:
When the elevator is not used within a set time, the lighting and fans in the car will be automatically turned off to save power.

Dedicated (VIP) service:
After the dedicated (VIP) service is started, the elevator will give priority to the VIP floor and open the door to wait, providing priority service for VIP. The display on each floor shows "dedicated". The elevator does not serve calls from other floors. If it is not used for more than 30 seconds, the elevator will automatically return to normal use.

Special floor control:
When some floors of the elevator need to be controlled for access, you can use a key switch or a preset specific time (or computer monitoring) to stop the service of a specific floor. (You can also choose a credit card machine for control)

Time-sharing and layered services:
In the case of continuous control of multiple elevators, the service of cutting off some floors can be preset within a specific time, so that the elevator can serve the floors with higher load capacity in a centralized manner.

Dot matrix LED display:
16x24 dot-matrix LED display in case of elevator failure, maintenance, full load, special use, fire protection, the floor display can display information in easy-to-understand Chinese (or English) to inform passengers waiting in the boarding station, and understand the operation of the elevator status.

MIB computer monitoring:
In the management room, a PC computer is used to monitor the operation status of all elevators in real time. If a failure or abnormality occurs, a red warning and failure content will appear on the elevator screen, and an alarm sound will be issued to notify the management , And archive the monitored abnormal information in real time to serve as reference data for customers or elevator maintenance personnel to diagnose elevators. The detailed operation status of each elevator is displayed in a dynamic graphic synchronization, such as elevator status, control status, fault information, car position, door opening and closing status, call status of each floor. Elevator control such as fault reset, fire recall, elevator lock and stop, special operation, floor control, elevator call to any floor, all can be operated by computer. (Optional)
