Mr. Hidenori Sekine, Elevator Development Dept. Hitachi, Ltd. Building Systems Business Unit: “Hitachi’s PES-02 electronic safety controller is a SIL 3 certified electronic safety device that is intended to be applied as an ‘add-on system’, independent from the elevator control system. It is able to fulfill several safety functions like amongst others check of emergency terminal slowdown and ascending car overspeed and detection of unintended car movement with open doors.
