Absolute Position Detection

Hoistway “GPS” to monitor the car position and speed in real time

ZFS–ELE200 uses absolute position detection to replace the conventional incremental indirect position detection, which enables the safety and control system to obtain the car position and speed more accurately. “Indirect measurement and estimate conversion” has become a thing of the past.

Industry-leading SETS Technology

Effectively reduce pit depth and overhead

ZFS–ELE200 integrates Smooth Emergency Terminal Slowdown (SETS) technology to ensure safety when the terminal slowdown system fails to work properly, and effectively reduce the pit depth and overhead of the hoistway. In addition, this technology also reduces requirements for civil engineering as well as the construction cost of buildings.

Integrate over 30 Safety Features

Ensure all-around operational safety at the system level

ZFS–ELE200 realizes various safety features, including car position and speed protection, unintended car movement protection and door lock contact detection. Its design optimizes the system structure, reduces the complexity of safety circuits, and improves the reliability for the entire elevator.

Improve Leveling Accuracy

Improve real-time performance and resolution of car position detection

LEHY–Pro uses absolute position sensors and traction machine encoders for control, realizing millisecond detection delay and position capture with a resolution of less than 0.03 mm and improving the leveling accuracy to no more than ± 5 mm.

Use High-performance Dual-core MCUs and Independent Physical Communication Channels

Secure, reliable and real-time safety assurance

ZFS-ELE200 adopts a dual-channel structure with diagnostics, with the logic part equipped with multiple safety MCUs that achieve SIL3/ASILD certification to provide signal monitoring and safety protection.

ZFS-ELE200 uses physical channels designed for safety communication to separate safety signals from non-safety signals to ensure information is transmitted in a reliable and timely manner and safety integrity meets SIL3 requirements.

  Passengers can ride an elevator through Bluetooth on their phone, without an IC card. They do not need to touch any button and can ride an elevator more safely.
• Identify and ride an elevator via QR code
  Passengers can ride an elevator by scanning the QR code with their phone, without an IC card. When they have visitors, they can generate a QR code and send it to the visitors to ride the elevator.

EleLink App (optional)

Maintenance Staff

In case of a fault, authorized maintenance staff can locate and fix the fault more quickly through the EleLink App, minimizing the impact of shutdown.

EleCare App (optional)

Attendant

• Property management staff can connect their phones with elevators through Bluetooth and use the electrical device control function on EleCare App to control all electrical devices in the car without any remote, including turning on/off and mode setting of lighting, fans and air conditioners. They can manage elevators more easily on the App.
  For example, they can set and adjust the color temperature and brightness intelligently on the App to create a more comfortable ride environment, and can easily control the lights as they like to create different atmosphere in the car at different periods through various pre-set modes.

• Property management staff can connect their phones with elevators through Bluetooth and use the elevator door control function on EleCare App to set common door functions, such as Independent Service Operation, IC Card, Attendant Service Operation, and Non-Service to Specific Floors. They can complete elevator settings more easily on the App.
  For example, when they enable Attendant Service Operation on the App, the elevator will be exclusively operated by the attendant. When Non-Service to Specific Floors is enabled, they can set which floors the elevator does not stop.
  

Water Ion Air Conditioners and Fans (optional)

Cleaner

• Equipped with Panasonic nanoeTM X water ion generator imported from Japan, which can kill attached bacteria and viruses.
• Equipped with high-sensitivity VOC sensors, which enable the fan to switch to the maximum speed for quick ventilation when smoke or unpleasant smell is detected.

More User-friendly

• Fan speed can be adjusted according to the load: The fewer the number of passengers is, the slower and the quieter the fan is.
• Fan speed can also be adjusted from a mobile app.

28.6" touch-screen operating panel (optional)

Industrial Capacitive Touch-screen

Use a 28.6" industrial capacitive touch-screen operating panel, creating strong visual impact and offering three UI designs to meet the requirements of different application scenarios and customers.

Fully Physically Toughened Glass Panel

When riding the elevator with a pet, a passenger can press the pet button to provide a visual indication for passengers at other floors.In so doing, passengers at other floors can decide to or not to ride the elevator as needed, to effectively avoid unexpected pet disturbance.

More accurate and reliable and safer intelligent MBS

• More intensive light beams to deliver more accurate detection: pairs of light posts > 35, number of light beams 169 (comply with EN81-20), providing better protection for passengers when they come in and out of the door zone.
• Intelligent MBS self-check mode ensures the MBS can function properly when the doors open each time to prevent dangers. (If the self-check fails, the doors will be closed slowly to reduce the kinetic energy and an alarm will be triggered.)
• Intelligent MBS can detect an disconnection or adhesion fault to avoid missed detection of an MBS fault.
• MBS is used to help detect whether the doors are closed to prevent the risk of man-made short circuit of the door interlock switch, providing better safety protection.

Intelligent Safety Features

• 24-hour self-check: Self check braking torque and balance coefficient automatically to ensure the healthy functioning of the elevator system.
• Car slide safety protection: When the car slides suddenly, the three-phase winding of PM traction machine is shorted to reduce the speed the car slides to minimize safety risks.
