SYSTEM COMPONENTS

One System, many Components

The Pitagora 4.0 electric system is composed of three main elements:

Shaft & Top of Car components

From main elements to ancillary devices, the Pitagora 4.0 electric system includes many components which are paramount to the correct functioning of the lift. See the main ones here

Pre-wired Fixtures

A wide range of car and hall fixtures, equipped with the best DMG components, starting from pushbuttons, displays and electronic devices. See all products on our website

CONTROLLER

This is the heart of the system, available in multiple layouts, power sizes and models, for both traction and hydraulic installations. See all the available models click here

TOC BOX

The Pitagora 4.0 Top-of-Car box is designed to match all requirements of EN81.20/50 code. It includes the remote inspection box  and cables to main devices installed on the top of the car (door operator, etc.).
Inside the box, the TOC board manages the serial communication between the controller and all the devices installed in the car.

POSITIONING SYSTEM

The Pitagora 4.0 system ensures smooth rides and great stopping accuracy at floor thanks to the way it handles the car position signal. There are fundamentally four types of car positioning system available:

For more demanding applications and complete modernizations, the optional Absolute Encoder allows for extra-accurate car positioning in all conditions. Furthermore, its certification eliminates the need for all electro-mechanical safety devices in the shaft.

Quick to install, simple and reliable, the DMG rope-and-pulley Encoder ensures accurate reading of car position. Top/bottom magnetic limit switches provide the reset signal. With this cost-effective solution, the Pitagora 4.0 offers great stopping accuracy and remarkable direct-to-floor approach also with open loop systems. This system is suitable in combination with the DMG UCMP solution, when requested.

This is the built-in solution for the car positioning system whenever a gearless machine is present in the installation. Like in the case of the DMG rope-and-pulley encoder, top/bottom magnetic limit switches provide the reset signal. This solution cannot be used in conjuction with the DMG UCMP system.

Only available for simpler installations with speeds up to 1 m/s, this conventional system to detect car position is fundamentally based on magnetic detectors positioned on the top of the car and a set of magnets at each floor.
