Electrical safety installation, e.g. electrical steering installation, control device, has micro-controller preventing data communication between control and safety installations and charging data transmission line

摘要

The device has a control installation (30) that generates a control signal to control an electrical safety installation (10) e.g. electrical steering installation. The control signal is transmitted by a data transmission line (18). A micro-controller (32) prevents data communication between the control installation and the safety installation and charges the transmission line to a positive potential and a reference potential.
