Control system for adjustment devices powered by electric motors and method for generating error-free control signals for adjustment devices powered by electric motors

摘要

The control system comprises a control unit (3), a power supply unit, and a patient manual switch (1) with operating elements for generating control commands. The patient manual switch is connected to the control unit by two signal lines (9). A processor (6) is provided for generating switching commands for controlling the adjustment device. An independent claim is also included for a method for generating fail-safe control signals for electric motor actuated adjustment device for beds, particularly for hospital beds or patient beds.
