Universal, flexible and scalable programmable electronic platform , which serves as a starting point for the design of any PESSRAL and UCM device according to UNE-EN81-20 and UNE-EN81-50.
This PESSRAL platform meets all safety requirements Functional in both hardware and software and serves as a reference for the development of new elevator safety devices and systems.
The platform is proposed as a system with the capacity to reach different SIL integrity levels, with the minimum necessary functionalities of so that certain dangerous situations can be provoked or simulated and check the correct operation of the safety system, avoiding such dangerous situation and allowing the elevator to remain in a safe state.
The system consists of two main security functions:
Two PESSRAL functionalities have been implemented at . The first of these detects the overspeed in the car of an elevator installation and activates the car detection means by means of an electrical setpoint. The second one has the function of detection of the uncontrolled cabin movement (UCM) and activation of the safety function.
These functionalities are considered parts of a basic system to which can add new functions, add or design new safety sensors, increase the number of actuators, etc., as required.
Due to the regulatory changes that have occurred in the elevator sector (elevator directive 2014/33/EU) and the increased complexity of functionalities and performance of elevators PESSRAL systems based on programmable electronics are emerging as the solution to reliably address these new challenges in the sector.For more information: activostecnologicos@itainnova.es.
