Control system for electrically controlled installations

A control system (1) for electrically controlled installations, comprising

• at least one electronic control device (7) for monitoring and controlling an installation (2) and/or installation components (3),
• at least one portable, mobile manual control unit (9) for displaying information and for inputting control commands, with an internal power supply unit (14) for the temporary, electrical power supply of the manual control unit (9),
• a wireless communication connection (8) between the at least one control device (7) and the manual control unit (9) for transmitting information and control commands between the manual control unit (9) and the control device (7),
• wherein
• at least one form-flexible, material coupling means (15) with a limited maximum longitudinal extension is provided, which coupling means (15) is provided via at least one coupling device (17) activated without the use of tools for the optional creation and disconnection of a physical link between the manual control unit (9) and at least one spatially fixed machine-side coupling counterpart (16), and
• at least one coupling state monitoring device (23) is designed for the continuous detection and monitoring of a mechanical coupling state of the at least one coupling device (17) and/or for the continuous detection and monitoring of a signaling connection state via the coupling means (15) between the manual control unit (9) and the at least one coupling counterpart (16),
• wherein the control system (1) is designed for enabling the input of supervisory-relevant control commands, in particular control commands to be monitored directly by an operator on the manual control unit in case of the detection of a created coupling state or an existing connection state and for blocking the input of supervisory-relevant control commands via the manual control unit in case of the detection of a disconnected coupling state or an interrupted connection state.
