Built-in functions
Automatic return to floor
The controller can be programmed to automatically take the car to a pre-set floor after a period of inactivity, thus optimizing passenger waiting times at the busiest floor.
Time zoning
Same as the AUTOMATIC RETURN TO FLOOR function, but with the possibility of programming up to four daily time slots in which to move the lift to the selected floor. This feature is particularly suitable for high-traffic duplex/multiplex systems to reduce waiting times and increase efficiency.
Code-protected floors
This function allows the creation of a custom code. Calls to protected floors will be enabled only after the custom code is entered using the buttons in the car panel.
Antinuisance
This function is designed to counteract small acts of vandalism in lifts. It allows you to set the number of stops at floors without passengers entering or leaving the car. Beyond this number, all remaining calls are considered nuisance calls and are therefore canceled.
Stay at floor
By pressing a combination of buttons on the car button panel ([FLOOR BUTTON] + 3x [DOOR OPEN]), the lift can be programmed to stop at the current floor for 5 minutes, preventing calls from other floors.
It therefore facilitates loading and unloading operations, for example during a move. The function is instantly canceled by making any car call.
Door pre-opening
It is possible to set the car doors to open just before the lift has fully stopped at a floor, speeding up and optimising lift waiting times (in some cases, a safety circuit and UCM protection is required).
Optional functions
Integrated load weighing device
For GEARLESS tractions lifts up to 1000kg, this innovative software feature, built-in the controller motherboard, allows to eliminate the need for conventional load-weighing devices.
This system accurately tells the cabin weight by reading the current output in the inverter immediately before the car moves.
Penthouse + Guest
Enjoy greater security and privacy with direct access to your private apartment or penthouse. This optional feature can be used to temporarily enable a car call button, normally protected by a key, allowing your guests to reach you directly using the lift.
Live+, video surveillance system
LIVE+ is a simple yet effective video surveillance system, fully integrated into your Pitagora 4.0.
It allows passengers to monitor one or more “at risk” exit floors (e.g. the exit to the garage or street level) directly via the in-car Matisse display.
The doors only open based on express consent from the passenger using the door open button.
Automatic emergency operation
In the event of a power outage, the lift is repowered via a UPS system to take the car to the nearest (or predetermined) floor and open the doors, allowing passengers to evacuate. A simpler system is also available for gearless traction elevators: the brakes are opened in a controlled way to gently bring the car to the nearest floor by gravity and open the doors.
Fire evacuation
In case of fire, this function offers two different evacuation options: single floor or multi floor.
Single-floor evacuation: the lift returns to a designated floor.
Multi-floor evacuation: multiple fire evacuation floors can be programmed in cascade. If one is
not available because of a fire alarm, the next one becomes the destination.
Floor priority
This key-secured function allows taking control of the lift cabin by giving priority to car calls while all landing calls are disabled.
This is vital for lifts located in special buildings such as hospitals.
Energy saving
When idle for a prolonged period, the PITAGORA 4.0 controller progressively enters “sleep” and “deep sleep” mode, turning off the car lights, the VVVF inverter, the position indicators and other devices.
In this way the energy consumed during stand-by (when typically the lift absorbs up to 90% of the total consumption) is optimized.
Functions for maintenance technicians
Automatic call test
This function allows your maintenance technicians to streamline and optimise their interventions on the system, carrying out automatic call tests without the technician actually being present. These tests are feasible both with the system in service and excluding the doors.
Prohibited floors
When you need to exclude access to one or more floors, you can enable this function remotely or on site.
Lift off function
Via a button on the external button panel, this function can call the car to a preset floor, putting the system in OUT-OF-SERVICE mode; the lift can be reactivated and put back into operation using the same simple process.
Other functions developed to verify that the main system devices are correctly installed.
