Shaft access For systems with encoder counting it is possible to activate the access procedure in the shaft without the system being stopped due to the interruption of the safety chain (opening of the landing doors). It is also helpful in EN81-1 installation. With the lift in normal operation: Keep…

The system has the following inputs for firefighters’ operations: POM input (key of floor): closing towards GND (NC / NO) I = 5mA CPOM input (elevator key): closing towards GND (NC / NO) I = 5mA Reference standards EN81-72:2015 – Firefighters lift (Europe) The EN 81-72 standard establishes the safety…

Procedures for system safety testings and for space-time measuring elevator car movement are described here. The following tests and measures may facilitate controls and tests to be performed before putting the installation in service (EN81-X D) and during the periodic maintenance interventions (EN81-X E). Some measures can be performed only…

Timing diagrams of the running commands according to the type of system.

Door command The door command board can command either one or two doors with alternative, selective or passage through opening. Output and inputs are available on the jst connectors on the TOC board and on APPO board (in the controller). The doors can be automatic, semi-automatic or manual: DOOR A…

Motherboard The control board of the Pitagora 4.0 system is based on 32-bit electronic technology and operates all types of electric and hydraulic lifts. Serial and/or parallel connections to pushbutton panels (cabin and floor) may be added. It is particularly suitable for VVVF electrical installations, also those equipped with the…

Learning procedure of floors If the Controller is equipped with Absolute Encoder or DMG Encoder or Motor Encoder it is possible to take advantage of the floor position learning feature, which allows for a faster system configuration and fine tuning. The procedure is different according to the type of encoder,…

The Pitagora 4.0 control panel can manage multiplex systems up to 6 lifts.The solution requires the use of a Q40.MULX electronic board mounted on the DIN rail of each control panel of the multiplex system. Each Q40.MULX multiplex board is equipped with two connectors (PREV / NEXT) and an ethernet…
